Enclosures & Clearances
Building Heating Appliance Chimney and Grease Duct systems are intended to be installed unenclosed or with non-combustible enclosures and are
not for use in one- or two-story family dwellings.
If the Chimney or Grease Duct passes through any zone or story of a building outside of which the connected appliance or hood is located, it is to be
enclosed in non-combustible construction having a fire rating equal to or greater than that of the wall or ceiling though which it passes. Check with
the local code authority (AHJ) for material with an appropriate fire rating. Do not wrap or place any type of insulation in the required
clearances space surrounding the Chimney in an effort to reduce the clearance to combustibles or to create some sort of fire protective enclosure.
Follow NFPA-96 regarding methods of reduced clearances for Grease Ducts.
Where, according to local code, no chase enclosure is required, Model DWKL/DWFL may be installed adjacent to a wall of combustible construction
at the minimum airspace clearance specified on each pipe section and in the individual Listing as shown in the following tables.

Vent Size
Refer to the appliance manufacturer’s installation instructions for proper sizing and vent configuration – contact Jeremias Technical Support for
assistance in this regard.
Horizontal Installation Requirements / Vent Slope
Any horizontally installed portion of a venting systems shall have a slope upwards not less than ¼” (6.4mm) every 12” (305mm) and be installed so
that condensate flows back toward the appliance or drain. The install must be such to prevent collection of condensates, formation of ice buildup or
blockage at any location of the assembly. Condensate must flow freely and may not be retained in any part of the vent system. Refer to appliance
manufacturer’s installation instructions for further details regarding the installation of condensate drain fittings and the pitch of the system. See Fig.
1-3. As an option, the installer may also use Jeremias 87° elbows and fittings that will create a slope of ⅝” (15.9mm) per every 12” (0.64mm). For
Kitchen Ventilation System, see Section 7 for slope requirements.
Application Minimum Slope
Condensing Gas Vent ¼” (6.4mm) Rise per 12” (305mm) Horizontal Run
Kitchen Grease Duct 1/16” (1.6mm) Rise per 12” (305mm) Horizontal Run
Vertical or Through-the-Roof Installation
Determine an appropriate path to route the vent system. See Termination
Requirements section for guidance on location. See Table 2-2 (DIM C) and Fig 2-1
for Maximum vertical unsupported height above the roof. If the vent length exceeds
this figure, it must be re-supported with a Guy Section or other horizontal support. If
necessary, cut holes in floors and ceilings to frame firestop plates. Exterior portions
of the vent located below the roof line should be enclosed to limit condensation in the
system. As an alternate, Model double-wall FL or KL may also be used.
Termination Requirements
Gas Vents
Location of the termination of the venting system should comply with the National
Fuel Gas Code, ANSI Z223.1, manufacturer's recommendations and/or applicable
local codes. See Diagram for typical terminal locations. See Fig. 1-4 & 1-5.
A. When venting through a sidewall, terminate the system not less than 12”
(.3m) above the ground and above the snow line in areas where snow
accumulates. The termination area must be kept clear of snow and ice at
all times.
B. Terminate the system at least 7’ (2.1m) above a public walkway or
driveway, no less than 6’ (1.8m) from the combustion air intake or any appliance or 3’ (.9m) from any other building opening, gas utility
meter, service regulator or the like. It must also terminate at least 3’ (.9m) above any forced air inlet within 10’ (3.1m) and terminate at least
4’ (1.2m) below, 4’ horizontally from or 1’ (.3m) above any door, window or gravity air inlet into any building as provided in the National Fuel
Code ANSI Z223.1 and NFPA 54. Proper judgment may require greater distances depending on the size of the equipment installed or to
allow for snow drift or fall from overhead roofs or trees.
C. The termination shall be far enough away from trees, shrubs or decorative items to avoid damage.

Model KL
Models DWKL and SWKL are
cylindrical, factory built, modular
exhaust systems that incorporate a
steel to steel conical joint and clamp
system for quick and easy assembly
in the field. The conical joint is
tapped in place creating a gas and
liquid tight seal where sealant is not
needed.
The conical joints have a 2.2” wide
steel to steel surface overlap area at
each connection allowing greater
stiffness, sealing, and durability.
The double wall Model DWKL is
insulated with 1¼” thick compressed
fiber which allows the inner and outer
pipes to stay aligned, without the use
of additional clips or brackets,
eliminating hot spots at the joint
connections.
Features of Model DWKL double wall and fiber insulated include:
• Easier to clean than field welded rectangular
• Reduced clearance to combustibles
• Reduced outer pipe skin temperatures
• Reduced building heat gain
• Increased efficiencies of energy recovery systems
• Reduced noise levels caused by high velocity exhausts
The single wall Model SWKL can be used as an option for Unlisted Metal Chimneys
(Smokestacks) or single wall Steel Pipe Connectors as defined by NFPA-211. Model SWKL is
intended for an entirely non-combustible surrounding and must be installed in strict accordance
with NFPA-211 requirements for single wall stacks and connectors.
Further features of Model SWKL single wall include:
• No field welding
• All stainless-steel construction
• Smooth flowing inner liner
• Wide array of accessories such as supports and drains
• May be connected to and from DWKL
Joint Assembly – Model KL
The Model KL joint system is designed for a quick and easy installation. The procedure for DW Double-
wall and SW single-wall are identical. See Figs 1-5 to 1-10.
To Assemble:
1. Clean the inner side of the female end and the outer side of the male end of each inner liner.
Apply the KL Paste to the female end.
2. Position both pipes so they are in alignment. Engage the pipes and press them together as much as possible by hand.
3. Position the Wood Plate (supplied with shipment) and on the end of the assembly.
4. Tap Wood Plate 2-3 times. Make sure to push both inner and outer pipes at the same time; the inner should not be more than 1/8” longer
than the outer pipe once the male/female conical ends are engaged.
5. Position the Locking Band (LB) around the joint and ensure grooves in LB are seated in the Pipe grooves.
6. Secure LB, using 5/16” nut driver or flat-head screwdriver to tighten gear clamps

Installed Vent Length
Due to the engagement of the vent sections, the effective installed length of any vent pipe or fitting is 2-3/16” less than the described length.
KL Paste
KL Paste is a ceramic lubricating and assembly paste. The purpose is to help guide the pipe connections to assure the best s teel to steel
connection. It also seals the joint by allowing the ceramic to fill any microscopic steel imperfections. On fitting s it will help the installer rotate to the
correct position before tapping in place.
Use approximately 1 teaspoon of paste per 24” length of joint
perimeter. Example: 10 inch diameter has 31” of perimeter length,
so use about 1.3 teaspoons per each 10 inch joint connection.
Below table allows for a 20% waste.

Joint Assembly – Model FL
Model FL inner connection has 1.25” overlapping joint with ½” rolled flanges that are connected with
a V-Band. The overlapping “spigot” facilitates alignment of pipe sections, provides support during
assembly and protects the sealed joint during cleaning. The spigot should always be positioned
down, back toward the appliance. Follow the flow direction arrow on the product label. If necessary,
it is permissible to remove the spigot (with a cutting wheel or similar) to allow installation in tight
spaces.
To Install:
1. Position the pipe so the UP/FLOW arrow is in the direction of the flue gas flow
2. Select correct sealant based on flue gas and application:
a. J-2000 Sealant for Flue Gas temperatures up to 2,000F. High temperature
Heating system or Engine exhaust
b. J-600 Sealant for Flue Gas temperatures up to 600F. Low temperature heating
system or Grease Duct.
3. Prepare all surfaces where sealant will be applied. Be sure all surfaces are
clean of dirt and oil. Follow preparation instructions included with
corresponding sealant.
4. Apply J- Sealant continuously (1/4” bead minimum) to the flange surface of the
pipe (See Fig 1-11)
5. Join Flanged surfaces together. Ensure the Flow arrows are in the direction of
the flue gas flow
6. Apply sealant to the inner groove of the V-Band (see Fig 1-11)
7. Position the V-Band around the joint, capturing the flanges in the groove of the
V-Band
8. Install fasteners in V-Band retainer and tighten hardware. Tap the V-band to
allow it to seat tightly against the flange.
9. Wrap the joint with insulation (DWFL+ only). See Fig 1-12.
10. Position the Locking Band (LB) around the outer pipe (DWFL Only)
11. Tighten hardware on Locking Band to secure (flat head screw driver or 5/16”
nut driver)
12. For exterior installations, apply Dow 732 (grey) sealant around the
circumference of the locking band seam. See Fig 1-13.

It may be suspended by threaded rods or angle iron. See Full Angle Ring
(FAR) for outdoor or vibrating installations. See Fig 2-10.
Full Angle Ring (FAR)
The Full Angle Ring is used as a vertical guide to keep system aligned and
provide horizontal support. It is braced to the building structure by the
installing contractor. It can also be used in horizontal configurations where
exposed to weather (wind) or on vibrating or high-pressure applications such
as engine exhaust. See Figs 2-11 & 2-12
Light Support Band (LSB)
The Light Support Band can be used on low pressure and low temperature
applications such as heating boiler stacks (not for use with engine or turbine
exhaust) for support/guide in horizontal or vertical installations.
The band firmly clamps around the pipe outer jacket and includes four (4) ¼”
x 20 stainless steel nuts and bolts. Remaining hole in the middle where
wires or threaded rods (by the installing contractor) are used for support or
guiding back to the building structure. See Fig 2-13.
Guy Wires Band (GWB)
The Guy Wires Band permits easy connection for three (3) guy wires at 120
degrees apart. The band firmly clamps around the pipe outer jacket and
includes three (3) ¼” x 20 stainless steel nuts and bolts. See Fig 2-14.
The actual guy wires are by others, the structural engineer should select
wire size and guy tensioners in accordance with good engineering practice
to suit each specific application. See Fig 2-15.
Rigid Bracing
Rigid bracing is advantageous over guy wire
bracing, as less maintenance is required to
accommodate for thermal expansion. Rigid

SECTION 3 – PIPE & OTHER LENGTHS
Fixed Pipe Lengths (__L)
Models KL and FL are available in a variety of fixed pipe lengths (e.g., 6”, 9”, 12”, 18”, 24”, 30”, 36”, 42”, &
48”). Refer to the catalog for available sizes. Additionally, where required, custom lengths may be ordered
from Jeremias Inc. Refer to the corresponding Joint Assembly section for installation instructions.
Adjustable Length (AL) [Model FL]
The AL is used where odd length of vent is required. It is not intended to accommodate thermal expansion.
The AL includes a Slip Section, an RCO and a Clam-Shell style outer jacket (Double-Wall only). The
minimum installed length is 8” long. The Maximum installed length is 22” long.
To Install (See Figs 3-2 & 3-3):
1. Loosen Clamp on RCO and adjust/slide the Flange to the required location.
2. Clean/Prepare surface and apply sealant between the Slip Section and RCO to create a seal.
3. Tighten RCO clamp to secure it in place.
4. Install AL assembly to the adjacent pipe. The Slip Section will slide to the inside of the adjacent pipe. If the Slip Sectio n is too long and
interferes with elbow or other component, the extra length can be cut off.
5. Join the flanged ends to the adjacent pipe sections with V-Band. Refer to Joint Assembly section for proper sealant usage and joint
connection method.
6. Wrap the inner flue with provided insulation (DWKL/FL+1 option only)
7. Install outer around AL (DWFL options only). The outlet end of the Outer jacket has a chamfer that will seat in the bead. The Lower end of
the Clam Shell is clamped flush against the outside of the pipe.
Adjustable Length (AL) [Model KL]
The Model KL AL is used where odd length of vent is required and incorporate a telescoping
length that compensates inner thermal expansion. These adjustable lengths ship completely
assembled, and no modifications are required in the field.
Adjustable Lengths (AL) are intended to be used in negative internal pressure applications
only. For positive pressure applications use Adjustable Lengths w/ Gasket (18AG or 30AG),
Adjustable Lengths w/ Graphite Packing (18ALG or 30AG), or Lined Bellows Length (LBL).
• The minimum installed length of the 18AL is 10.5”.
• The maximum installed length of the 18AL is 15.5”.
• The minimum installed length of the 30AL is 22.5”.
• The maximum installed length of the 30AL is 27.5”.

Adjustable Length with Graphite Gasket (ALG) [Model FL]
The ALG is used to accommodate for thermal expansion and where odd length of vent is required.
The Adjustable Length with Graphite Packing has been evaluated by UL and confirmed
suitable for positive internal static pressures up to 8” WC (2000 Pa).
The adjustable length incorporates a telescoping inner liner that accommodates thermal
expansion in longer runs of pipe. It telescopes into a larger diameter stationary length
and is sealed by a heavy gage clamp/graphite packing sealing system. It is finished off
with a clam shell outer jacket.
When also using the Adjustable Length to make up for an odd length, you must remove
the outer jacket and loosen the clamp/graphite seal to allow the telescoping inner to
easily slide further into the stationary length. The insulation may need to be trimmed
back also. Tighten the sealing system back in place.
The minimum installed length of the 24 ALG is 6”. The maximum installed Length is 22”.
Do NOT extend the telescoping inner outwards beyond the maximum installed Length.
In horizontal Adjustable Length installations, always add guides near each end to assure
correct alignment. In vertical installations, place the Adjustable Length just below a
Support as the Adjustable Length is not load bearing.
To Install (See Fig 3-5, 6, 7 & 8):
1. Remove bolts and separate the Lower 2-Piece ring from the Graphite
sealing system.
2. Wrap the Lower 2-Piece ring around the inner liner (just below the flange)
of the adjacent stationary section.
3. Slide the ALG Slip Section down, inside the adjacent stationary length
with Lower 2-Piece ring from Step 1.
4. Join the Upper Ring with Containment Lip to the Lower Ring. The
Graphite Band and Flange from Stationary Length should be sandwiched
between Ring sections.
5. Secure Rings together with bolts provided
6. Tighten all hardware on Containment Rings.
7. Wrap inner flue pipe with insulation provided (DWKL/FL+1 only)

Adjustable Lengths W/ Graphite Packing (__ALG) [Model KL]
Adjustable Lengths with Graphite Packing have two functions: to serve as an
expansion joint and to make up for a required odd length. The adjustable length
incorporates a telescoping inner liner that accommodates thermal expansion in
longer runs of pipe. It telescopes into a larger diameter stationary length and is
sealed by a heavy gage clamp/graphite packing sealing system. It is finished off
with a clam shell outer jacket.
Adjustable Lengths ship completely assembled at the “maximum Installed Length”
shown herein, and no modifications are required in the field when used only as an
expansion joint.
When also using the Adjustable Length to make up for an odd length, you must
remove the outer jacket and loosen the clamp/graphite seal to allow the telescoping
inner to easily slide further into the stationary length. The insulation may need to be
trimmed back also. Tighten the sealing system back in place.
To assure correct engagement of the inlet and outlet ends, the Adjustable Length
must be installed to the connecting pipe or fitting while the graphite seal is tightened
(either before loosening as the adjustable ships or after tightening when used to
make up an odd length).
The Adjustable Length with Graphite Packing has been evaluated by UL and
confirmed suitable for positive internal static pressures up to 8” WC” (2000 Pa).
• The minimum Installed Length of the 18ALG is 11.3”
• The maximum Installed Length of the 18ALG is 15.8”
• The minimum Installed Length of the 30ALG is 17.3”
• The maximum Installed Length of the 30ALG is 27.8”
The above figure shows Model SWKL which is the same as the inner liner of Model
DWKL.
Do NOT extend the telescoping inner outwards further away from the stationary
length than the above “maximum Installed Length”.
In horizontal Adjustable Length installations, always add guides near each end to
assure correct alignment. In vertical installations, place the Adjustable Length just
below a Support as the Adjustable Length is not load bearing.
Adjustable Length with Gasket (AG) [Model KL]
Adjustable Lengths with Gasket incorporate a telescoping length that compensates
inner thermal expansion. These adjustable lengths ship completely assembled, and
no modifications are required in the field.
• The minimum installed length of the 18AG is 10.5”.
• The maximum installed length of the 18AG is 15.5.
• The minimum installed length of the 30AG is 22.5”.
• The maximum installed length of the 30AG is 27.5”.
A gasket is factory installed to provide a maximum 0.8” W.C. (200 Pa) of positive
pressure capability. The Adjustable Lengths w/ Gaskets are also limited to
natural/propane gas and 400°F (200°C) maximum continuous internal operating
temperatures (this part is not for use with solid fuel or oil). For higher positive
pressures and/or temperatures use Lined Bellows Length (LBL).

Cut Length (18” & 30”CL) [Model KL only]
Cut Pipe Lengths are specifically
engineered to be field cut to desired
length. This permits the greatest
flexibility for complicated installations.
CLs are available in 18” & 30” length.
• Minimum installed length of
18CL and 30CL is 5.3”.
• Maximum installed length of the
18CL is 15.8”.
• Maximum installed length of the
30CL is 27.8”.
Cut Pipe Lengths are used in all
applications and have been evaluated by
UL and confirmed suitable for positive
internal pressures up to 60” W.C. (15000
Pa).
IMPORTANT: Proper installation of the
Cut Pipe Length involves a procedure of
very careful measurement and cutting
(either in the field or shop) of the outlet
end(s) of the Cut Pipe Length with
appropriate equipment and technique to
achieve a clean, burr free, straight
end(s). Experienced sheet metal
tradesmen are familiar with such
equipment and techniques and should be
used for such purpose.
Examples of equipment commonly used
for such purpose include:
Type 27 Right Angle Grinder Cutting
Wheels for stainless steel and NOGA
Model DB1000 double edge deburring
tool for thin sheet metal.
Cut pipe length ships as a standalone
item. Arrow shows direction of flue gas
flow, or up direction.
To Install (See Fig 3-13 & 14.).
1. Field measure required
distance to fill between two
pipe ends.
2. Add 4.4” to determine the
overall cut pipe length required.
The minimum overall permitted
length is 7.5”.
3. Measuring up from the inlet end
of the cut length, mark and create a line around the perimeter of the cut length at the desired location for the cut.
4. Using the line as a guide, cut the extra material (outer wall, insulation, and inner liner) away leaving the desired overall length.
5. Deburr the edges of the inner and outer cut.
6. On the outer wall of the cl, measure and create a second line 2.2” back from the cut end.
7. Apply kl paste to the outer surface of the connecting inner pipe.
8. Tap the adjoining length or cut length into place using the supplied wood plate. Proper engagement is achieved when this dim ension (*)
becomes zero.
9. Install the locking band (lb.) from the adjoining pipe section over the field cut joint location.

SECTION 4 – FITTINGS, TEE CAPS & INCREASERS
Special Considerations for Fittings
Notice: Tees, Elbows and other fittings must be protected from forces caused by
thermal expansion and system weight. Where thermal expansion exceeds 0.375”
prior to the fitting, it must be anchored with a support and provisions for thermal
expansion be provided. After the fitting, the system is to be re-supported to
accommodate weight from additional vent lengths. See Fig 4-2.
Elbow (__EL)
Elbows are used to provide changes in direction. They are available in a variety of
standard angles (1.5°, 3°, 15°, 30°, 45°, 70°, 87°, & 90°). Refer to the catalog for
available sizes. Additionally, where available, custom lengths may be ordered from
Jeremias Inc. Elbows are installed similar to standard pipe. Refer to the
corresponding Joint Assembly section for installation instructions.
TEE (__T)
Used as a manifold entry Tee, offset with one of the access cap options, or base Tee
with one of the drain tee caps options. Snout can be same or any size smaller than
the body.
87° & 90° Boot Tee (__Bt)
Jeremias Boot Tees offer the added 45-degree gore that directs the flue gases
towards the outlet at a 45-degree angle. Most others still allow the flue gases to enter
the outlet branch at 90-degrees. Snout can be same or any size smaller than the
body.
45° Double Tee (45DT)
Used as a two-way manifold entry Tee, offset with one or two of the access cap
options, or base Tee with one of the drain tee caps options. Snouts can be any size
smaller than the body. See Fig 4-4.
90° Wye Tee (90WT)
Used for two-way entries where a tee cap or access cannot be used due to the
application or as a 90° that can have an access cap at the middle. See Fig 4-5.

Tee Cap Access (TCA)
Tee Cap Access permits access to the inside of the vent for inspection and/or
cleaning. It can be placed at the end of a snout of any three or four-way fitting.
Gasket and hardware are included so that the internal cap may be removed and
reinstalled. See Fig 4-6.
Increasers and Reducers
Reduction fittings are typically used in manifold applications when needed.
There are many options for increasers and reducers.
Tapered Increaser & Reducer (TI & TR)
Tapered Increasers and Reducers keep the same centerline. Be cautious of
using these in the horizontal, due to increased or decreased diameter changes
this will cause a low point in the exhaust where condensate can trap. Use the Eccentric increaser and
reducer in horizontal installations instead.
Tapered Eccentric Increaser & Reducer (TEI & TER)
Tapered Eccentric Increasers and Reducers keep the same low point or are flat on bottom. They also create
a slight centerline offset if used in the vertical installation
Stepped Increaser & Reducer (SI & SR)
Stepped Increasers and Reducers can be used in tight situations and are available in all steps.
The stepped increasers and reducers are non-structural part and must not be subject to loads in either the
axial or lateral directions.
Be cautious of using these in the horizontal. Increased or decreased diameter changes will cause a low point
in the exhaust where condensation can trap. Use the Eccentric increaser and reducer parts in horizontal
installations instead.
Stepped Eccentric Increaser & Reducer (SEI & SER)
Stepped Eccentric Increasers and Reducers can be used in tight situations and are available in all steps.
The Stepped Eccentric Increasers and Reducers are non-structural part and must not be subject to loads
in either the axial or lateral directions.
Condensate Drains – Universal Drain Length (UDL), Drain Tee Cap for Support (DCSS), Drain Tee
Cap Side (DCS), Drain Tee Cap Bottom (DCB)
If appliance instructions or local code calls for a condensate drain, use a Jeremias drain fitting and tubing
of appropriate size to route the condensate into the sanitary sewer drain.
Installation requirements:
A. Install this drain fitting as close to the appliance flue collar as possible.
B. When transitioning from horizontal to vertical, install Drain Tee Cap Side (DCS) or Drain Tee
Cap Bottom (DCB) at bottom of Tee.
C. For a straight horizontal run, install Universal Drain Length (UDL). Rotate fitting so that the
drain tube points downward.
D. Connect Condensate Drain Tube to fitting. Form drain tubing into a loop. Loop must be a
diameter that is at least 4 times the appliance's rated stack pressure in inches of water
column.
E. Prior to final assembly prime the drain loop by pouring a small quantity of water into the
drain tube.
F. Follow all local and national codes and regulations for the draining of acidic condensate.
G. Do not install drain tube in cold areas where ice can form causing potential damages and
hazardous conditions.
H. Do not use copper as a drain as it may corrode.

DRAIN TEE CAPS (DCB & DCS)
Two styles of Drain Tee Caps are available. Each includes a 1” NPT Nipple for
a drain line attachment by the installing contractor or use of Jeremias’ Drain
Tube Kit.
The DCB (B for Bottom) has the nipple at the base. The DCS (S for Side) has
the nipple on the side which is convenient in certain applications where the
horizontal appliance outlet is very low to the floor.
Drain Tube Kits (5dk & 10dk)
The Jeremias Drain Tube Kits contains:
1. 1” N.P.T to ⅝” hose coupling
2. Hose clamp
3. ⅝” Silicone Tube in 5’ or 10’ length
4. Two (2) cable ties
When installing the Drain Tube Kits be sure make a trap by forming a 5” diameter loop and secure with the
provided cable ties. Fill the trap with water before attaching the tube to the coupling and securing the hose clamp.
Check local codes/regulations to determine how the condensate fluid is to be drained. Local regulations may
require the use of a neutralizer kit when using a condensate trap. A condensate pump may also be required.
Contact the appliance manufacturer or local distributor if the neutralizer kit and/or condensate pump is required.

Terminations
See SECTION 1 - GENERAL INFORMATION for termination height above roof requirements.
There are two options to most terminations:
No Screen (N) or With Screen (S).
Jeremias uses 1” x 1” x 0.059” thick stainless-steel wire mesh for termination screens. The
purpose of a screen is to not allow debris or personnel into the exhaust and also used to
restrict rodents or birds from entering the exhaust.
Horizontal Terminations
There are several terminations available to terminate a horizontal system. Horizontal termination
options include Exit Cone (EC), Miter Cut Termination (MCS), Tee Termination w/ Screen (90TT),
30° & 90° Elbow Termination w/ Screen (30ET / 90ET) and Opened Termination (OTN). All
horizontal terminations must extend a minimum of 6” from the wall. Reference Joint Assembly

No-Loss Weather Head (NLWH)
The No-Loss Weather Head (NLWH) incorporated as part of the Jeremias Inc. DW KL/FL and SWKL/FL
product offering is the same type and construction as no loss weather head style terminations used for vent
applications in North America and other parts of the world for decades.
It is a very popular style of termination that provides the unique combination of appreciable rain protection
without any obstruction to the vertical exit of the flue gases. It is detailed in American Conference of
Governmental Industrial Hygienists (ACGIH) and American Society of Heating, Refrigeration and Air -
Conditioning Engineers (ASHRAE) handbooks.
At present (June 2014), Underwriters Laboratories, Inc. (UL) has no safety standard for these devices so
although they are shown in this document and condoned by NFPA, Jeremias Inc. and others, UL has not
independently investigated this product.
If the total height exceeds the freestanding distance (Dimensions C) as shown in Section 1 – Support and
Guiding, the structural engineer should support and guy the No-Loss Weather Head in accordance with good
engineering practice to suit each specific application.
The No-Loss Weather Head incorporates the Open Termination (OTN) at the base and connects to the

pipe I.D. plus 6”. The maximum wall
thickness is 11½”.
High Temperature Thimble (HTT)
This roof thimble provides safe installation against combustible materials. It is part of the Unvented and the
Vented Roof Assemblies (see Figure 6-6). Only for DWKL/FL use.
The thimble is fiber insulated and includes a lateral pipe guide with hardware at the top. The thimble extends
12” from the installation brackets. Hardware to connect brackets to the roof or wall is not included.
Roofs with A Slope or Pitch
When using the roof thimble with sloped roof construction, the installing contractor has two choices:
1. Fabricate a flat, horizontal curb for installation of the roof thimble shown. The curb extends out from
the high side of the roof opening.
2. Order a special version of the roof thimble that has the brackets factory installed to match the
desired roof pitch.
In all cases, it is important to ensure that the thimble body extends down at least 1” past the
lowest portion of the roof framing when installed. Thimbles with extended length bodies are
available on special request from the factory.
Flashings
A flashing is used to seal off the opening where the vent passes through the roof. Choose the
correct flashing to match the vent size and pitch of the roof.
To install (See Fig 6-7 & 8):
1. Ensure the proper clearance to combustibles is maintained.
2. Position the flashing over the vent. The upper end of the flashing is installed
underneath the roofing material. The lower end of the flashing is installed on top of
the roofing material.
3. Seal the flashing in place and secure with appropriate roofing fasteners.
Flat & Pitched Roof Flashings (FRF & PRF) & Storm Collar (SC)
The Flat Roof Flashing and Pitched Roof Flashing can be used for non-combustible
construction and also fit over the Roof Thimble (HTT) as part of the Roof Assembly with
Thimble when DWKL/FL is used for chimney or vent applications with 1000°F flue gases
or less. The Storm Collar flashes above the roof flashing and is sealed to the outer jacket
(but not attached to the flashing permitting expansion).
Flat & Pitched Cone Flashings (FCF & PCF) & Storm Collar (SCCF)
The Flat Cone Flashing and Pitched Cone Flashing can be used for non-combustible
construction. The Storm Collar for Coned Flashings flashes above the Cone Flashings
and is sealed to the outer jacket (but not attached to the flashing permitting expansion).

Unvented Roof Assembly
UL has determined the Roof Thimble (HTT) alone, without ventilation, provides a safe
installation through a combustible roof for Model DWKL/FL applications with 1000°F flue
gases or less. This also applies to enclosed Special Gas Vents, Type B Vents, and
Type L Vents. In this manner, the Flat Roof Flashing (FRF) in conjunction with the
standard Storm Collar (SC) is used. (See Fig 6-10).
Ventilated Roof Assembly
Ventilated Roof Flashing (VRF) and the Ventilated Storm Collar (VSC) are used in
conjunction with the HTT High Temperature Insulated Thimble to provide a safe
penetration through a combustible roof for all UL-2561 applications (1400°F maximum
continuous temperature). (See Fig 6-11).
Ventilated roof flashings

The Ventilated Roof
Flashing is larger than the
Flat Roof Flashing and
incorporates tabs to allow
air to flow under the
Ventilated Storm Collar.
Firestop Spacer (FS)
FIRESTOP SPACER (FS)
The Firestop Spacer is for use when penetrating a non-fire resistance rated ceiling or floor in
installations where a separate fire rated enclosure is not required. Available in all diameters for
DWKL/FL, only 3” and 4” diameters for SWKL/FL.
To Install:
1. Establish the correct framing dimension (See Table 1-2)
2. Nail the Fire Stop to top of the joist to prevent insulation from falling into the joist.
3. Route the vent through the Fire Stop plate.
4. Keep all attic insulation the proper minimum clearance from pipe by installing an enclosure
or similar around the pipe.
Storm Collar
A Storm Collar is used to seal off the opening between the vent and flashing.
To Install (See Fig 6-9):
1. Position Storm Collar around vent and against the opening of the flashing.
2. Tighten worm gear to secure Storm Collar in place.
3. Apply sealant around seam between Storm Collar and vent.
Roof Jack
The Roof Jack is required where single-wall model SWKL/FL passes through a combustible roof structure.
To Install (See Fig 6-13):
1. Slide the Roof Jack down inside the Flashing.
2. Position the tabs on the Roof Jack so that it is suspended from the top edge of the flashing.

Heat Shield (HSDW)
The Heat Shield is a light weight ventilated shield intended to
lower the skin temperature of an installed DWKL/FL double wall
exhaust system where personnel might be able to touch the
installed exhaust system.
The Heat Shield has been UL evaluated to provide a maximum of
70°F rise skin temperatures with flue gas temperatures at 1000°F
continuous or less.
IMPORTANT:
• Not for use with single wall SWKL system.
• Not used to change required surroundings and air
space clearance to combustibles as shown in Part 1
General Information.
The Heat Shield consists of a ventilated shell that wraps around
an installed DWKL/FL pipe. Spacing clips center the Heat Shield
around the DWKL/FL pipe. The Heat Shield increases the DWKL outside diameter by 3”. Total width of the
DWKL/FL insulation and added Heat Shield, or distance from inside of pipe to outside of installed Heat-
Shield is 2¾”.
To Install:
1. The DWKL/FL system must be completely assembled and supported before installing the Heat
Shield.
2. Unwrap the Heat Shield. The Heat Shield is factory packaged and delivered in a tighter roll
(typically inside a DWKL/FL pipe length, or by itself with straps holding its cylindrical shape).
3. Place Heat Shield around the installed DWKL pipe.
4. Tighten the worm gears to a snug fit, the spacing clips will hold the Heat Shield in place in both
horizontal and vertical installations.

SECTION 7 – Kitchen Ventilation Systems
Single Wall
In Grease Ducts, the single wall Model SWKL & SWFL are intended to
be an alternative option to field welded kitchen exhaust ducts as defined
by NFPA-96. In this application these models have the same air space
clearance to combustibles as field welded.
Slope
Mechanical codes and good practice require that some slope (back to a
grease reservoir or kitchen hood) be created to prevent pooling of grease
within horizontal portions of grease duct systems. Per code, grease duct
systems are required to incorporate a minimum ¼” per foot slope. Some
codes require ¼” per foot for runs less than 75’ in length and 1” per foot
for runs of 75’ and more.
While such slopes are critically important for flat bottom grease ducts in
order to prevent pooling, it is well acknowledged that cylindrical ducts
prevent pooling with far less slope.
Engineering analysis, including hydraulic fluid calculations and tests
confirm that pooling of grease within factory-built, cylindrical grease duct
systems can be achieved with far less slope compared to flat bottomed
systems, due to the physical characteristics of their construction.
As such, per the terms of the UL Listing and in accordance with UL1978,
Jeremias recommends a minimum slope of 1/16” per foot (0.3 degrees)
for horizontal segments of the KL / FL grease duct systems. Normal
system components will permit such slopes to be achieved on horizontal
offsets of at least 2’ in dimension. Shorter runs require no slope. Where
a specific slope is desired, Jeremias offers various options including
1.5°, 3° and 87° elbows as well as 87° tees.
Access for Cleaning Grease Ducts
Follow NFPA-96 for required openings in Grease Duct for accessibility required for thorough cleaning. Following are some openings requirements as
mentioned in NFPA-96:
1) Openings at changes of direction, if not accessible from the duct entry or discharge.
2) Access panel openings for installation and servicing of fire-extinguishing systems.
3) Access for cleaning and inspection where fans with ductwork connected on both sides within 3’ of each side of fan.
Horizontal grease ducts only:
4) Opening for thorough cleaning at 12’ intervals, where opening is not large enough for personnel entry.
Vertical grease ducts only:
5) Access at the top of a vertical riser to accommodate personnel descent.
6) Where personnel entry is not possible, access at every floor.
Model DWKL and SWKL have two standard options for access panels in Grease Duct systems. These are no-tool in design and specifically tested
and Listed for Grease Duct use.
Inline Access Door (IAD), see Section 3.
Grease Duct Tee Cap Access (GTCA), see Section 4.
For Model SWKL single wall installations, it is permissible to install Listed Grease Duct Access Doors provided they are installed in accordance with
the manufacturer’s installation instructions.
Interconnection with Field Welded Grease Ducts
Model DWKL/FL and SWKL/FL systems are intended to be installed as a complete system without the use of other manufacturer or field fabricated
components. However, Jeremias recognizes the occasional requirement for a rectangular portion of grease duct due to space constraints at certain
locations in a system, or when making modifications or additions to an existing grease duct. In such a case, it is permissible to transition to and from
Model DWKL/FL and SWKL/FL Grease Duct to a code compliant, rectangular or round, welded steel grease duct and back again. In such a case,
Jeremias will manufacture and supply a custom single wall stainless steel transition, meeting code thickness requirements, that permits field welding
to or from the field welded duct section(s). Maintain the minimum air space to combustibles of 18” with these custom transitions. Follow NFPA-96
regarding methods for reduced clearances for these single wall custom transitions as well as the field fabricated grease ducts.

Grease Duct Tee (__GT & __GBT)
Grease Duct Tee fittings have a reversed snout that permits accessibility
for cleaning. This is available in every tee option; the arrows below
dictate exhaust flow.
Grease Tee Cap Access (GTCA)
Grease Duct Tee Cap Access permits access to the inside Grease Duct
for inspection and/or cleaning. It can be placed at the end of a snout of
any three or four-way fitting and incorporates a 1½” tall dam to prevent
liquid or grease from dropping out when opening.
Gasket and hardware are included so that the internal cap may be
removed and reinstalled without tools.
Inline Access Door Length (IAD)
The Inline Access Door is for the Grease Duct application and provides
an easy and no-tool access to the inside exhaust for cleaning and inspection. The Inline Access Door ships fully assembled, and no modifications
are required in the field.
To open the door, and gain access to the Grease Duct, follow these steps:
1. Unlatch the outer jacket clips and open the door (hinges are on the opposite side of the clips).
2. Remove the precut insulation blanket.
3. Loosen and remove the wing nuts.
4. Remove the inner door.
5. Access the Grease Duct.

SECTION 8 – High Pressure Exhaust Systems
18” LINED BELLOWS LENGTH (LBL)
The Lined Bellows Length (LBL) incorporated as part of the Jeremias Inc. DWKL and
SWKL product offering for engine exhaust applications is the same type and
construction as bellows lengths that have been used for engine exhaust applications
in North America and other parts of the world for decades.
These devices incorporate fully welded tubes (for the inner flue) of the same
(stainless steel) material as the rigid chimney lengths and contain corrugations in the
tube wall that provide for reducing the effective length via compression when force is
applied at each end.
They incorporate a slightly smaller diameter rigid length (internally) through which the
exhaust gases pass. Bellows lengths are fitted with the same inlet and outlet end
construction and dimensions incorporated in fixed lengths making them completely
compatible with other components.
Used between rigidly fixed supports, bellows lengths provide a very important means
of accommodating thermal expansion of other parts in the system (due to the high temperature exhaust gas within) by compressi ng while maintain
pressure and temperature capability without leakage.
At present (October 2018), Underwriters Laboratories, Inc. (UL) has no safety standard for these devices so although they are shown in this
document and condoned by Jeremias Inc. and others, UL has not independently investigated this product.
Pressure Relief Valve (PRV)
The Pressure Relief Valve (PRV) incorporated as part of the Jeremias Inc. DWKL/FL
and SWKL/FL product offering for engine exhaust applications is the same type and
construction as pressure relief valves that have been used for engine exhaust
applications in North America and other parts of the world for decades.
Pressure relief valves are recommended by Jeremias Inc. and (other chimney
manufacturers) on their chimneys - when used for engine exhaust applications - in
order to provide protection in the unlikely, but possible, event of a delayed ignition of
unburnt fuel in the system due to a malfunction of the engine. NFPA37 the
“Standard for Standard for the Installation and Use of Stationary Combustion
Engines and Gas Turbines” specifies the use of such a device in chimneys used for
engine exhaust applications.
At present (October 2018), Underwriters Laboratories, Inc. (UL) has no safety
standard for these devices so although they are shown in this document and
condoned by NFPA, Jeremias Inc. and others, UL has not independently investigated this product.
Option to Reinforce Fittings
An option to requiring the use the Pressure Relief Valve in engine exhausts is to add external reinforcement to each fitting in the system.
This is accomplished by using the Anchor Plate Support (APS) on the entry and exit
sides and then reinforcing with external 2” x 2” x ¼” angle. Use the Heavy-Duty
Base (HDB) to minimize field supplied framework.

Engine Flip Top (EFT & EFTH)
The Engine Flip Top / termination cap (EFT) shown herein and incorporated as part
of the Jeremias Inc. DWKL/FL and SWKL/FL product offering is the same type and
construction of cap that has been used for engine exhaust applications in North
America and other parts of the world for decades.
At present (June 2014), Underwriters Laboratories, Inc. (UL) has no safety standard
for these devices, so although they are shown in this document and condoned by
Jeremias and others, UL has not independently investigated this product.
The Engine Flip Top is designed to be installed either on a vertical or horizontal
exhaust. If installed in a horizontal configuration, the hinge must be on the top side.
A counter balanced weight opens the cap when there is a slight exhaust pressure.
For installation see corresponding Joint Connection section.
SECTION 9 – FINISHING STEPS, INSPECTION & MAINTENANCE
Final Check
Before completing assembly, recheck all joints to ensure the locking band has been properly installed and has captured the be ad. For
Category III and IV check joint for gas tightness. Confirm all clearances and support spacing is correct.
OPERATING PRECAUTIONS
Creosote and Soot – Formation and Need for Removal
When wood is burned slowly, it produces tar and organic vapors which combines with expelled moisture in the flue gases to for m creosote. The
creosote vapors condense in the cool chimney flue of a slow burning fire. As a result, creosote residue accumulat es on the inner pipe. If ignited, this
creosote makes an extremely hot fire.
For this reason, the chimney should be inspected at least once every two months during the heating season to determine if a c reosote or soot
buildup has occurred. If creosote or soot has accumulated, it should be removed to reduce risk of a chimney fire.
Important Notice
The UL listing for this product is void if components other than the Listed Components are used. All warranties, stated or implied, are void if the vent
or appliance is installed in a non-conforming manner. After installation, check all joints and supports to assure they are secure and functioning as
intended and are properly sealed for containment of flue gases.
Maintenance
Jeremias recommends that the entire system be checked by a qualified inspector at least once a year after the system is place d in service.
The installation must conform to the requirements of the appliance manufacturer’s instructions, the National Fuel Gas Code and local codes and
regulations.
