Figure 4. Possible Vent Congurations; Vertical and
Horizontal Terminations.
VENT CONFIGURATIONS:
Figures 4 shows the range of venting options, it shows
possible vent congurations if the unit is top vented,
for vertical and horizontal terminations, any layout that
remains within the shaded area is acceptable. Having the
fewest number of elbows is ideal, as they tend to disrupt
air movement. Using 45˚ elbows is preferable to using 90˚
elbows. Also, a shorter vent system will perform better than
a longer one.
NOTE: The total length of the vent pipes can not exceed
33 feet (10.1 m). Any combination of rise and run can be
used as long as it lays within the shaded area (a total of
three (3) 90° elbows or six (6) 45° elbows can be used).
In addition to what is shown, if a 90° elbow is used in the
horizontal plane, 3 feet (91.4 cm) must be subtracted from
the allowable horizontal run (for each 45° elbow, 1 feet
must be subtracted from the allowable horizontal run).
VENT RESTRICTOR RING:
A vent restrictor ring is supplied with each direct vent replace. This
restrictor ring is to be installed when the vertical chimney installation
is over 15 feet (4.57 m). Before the chimney is placed onto the stove,
place this vent restrictor ring into the 4 inch (10.2 cm) ue pipe (as
shown), once the vent restrictor ring has been installed, the vertical
sections of chimney can be installed.

VENT PARTS:
This replace have been tested and certied for use with SIMPSON DURAVENT TYPE GS PIPE FOR GAS STOVES.
SELKIRK DIRECT-TEMP SYSTEM SECURITY CHIMNEY’S “SECURE VENT DIRECT VENT SYSTEM” and SELKIRK
“DIRECT TEMP VENT SYSTEM” kits are available for horizontal venting. When using Simpson Duravent, it is
recommended that, before installation, a bead of RTV High Temperature Silicone should be applied to each outer
vent joint, and Mil-Pac to each inner joint. When planning an installation, it will be necessary to select the proper
length of vent pipe for the particular requirements.
A MINIMUM VERTICAL LENGTH OF 24” (61 cm) TO THE FIRST 90° ELBOW IS REQUIRED. WITH THIS
MINIMUM VERTICAL RISE, HORIZONTAL RUNS OF FROM 1 FOOT (30.5 cm) to 3 FEET (91.5 cm) ARE PERMITTED
TO REACH THE OUTSIDE VENT TERMINATION.
BEFORE BEGINNING THE INSTALLATION TAKE CARE TO ENSURE AN APPROPRIATE OUTSIDE LOCATION FOR THE
VENT TERMINATION CAN BE ACCOMMODATED. FOLLOW THE VENT LENGTH DIAGRAM PRECISELY.
VENTING TERMINALS CANNOT BE RECESSED INTO A WALL OR SIDING.

PLANNING YOUR INSTALLATION:
When planning your installation, it will be necessary to select the proper length of vent pipe for your particular
requirements. It is important to note when passing through a wall, the maximum allowable wall thickness is
10 inches (25.4 cm), 1 inches (3.8 cm) clearance to combustibles must be maintained. Select the amount of
vertical rise desired for “vertical-to-horizontal” type installations. To determine the length of vent pipe required for
vertical installations, measure the distance from the appliance ue outlet to the ceiling, the ceiling thickness, the
vertical rise through the attic or second story, and allow for sufcient vent height above the roof line. For two story
applications, a re stop is required at each oor level. If an offset is needed in the attic, additional pipe and elbows
will be required. To connect the venting system to the appliance ue outlet, a twist-lock adapter is built into the
appliance at the factory. Refer to ‘Vent Conguration and Restrictor Settings’ for venting parameters.
Your total vent pipe length must be within the shaded area of Figure 4. If a 90° elbow is used in the horizontal
plane, 36” (91.4 cm) must be subtracted from the allowable horizontal run.
There are three (3) basic types of Direct Vent System installations. The two (2) types of installations are:
Figure 6: Common Horizontal Installation.
Figure 7: Common Vertical Installation.

HORIZONTAL INSTALLATION:
STEP 1. Set the appliance in the desired location. Check to determine if wall studs or roof rafters are in the way
when the venting system is attached. If this is the case, you may want to adjust the location of the
appliance.
STEP 2. Direct vent pipe and ttings are designed with special twist-lock connections. Assemble the desired
combination of black pipe and elbows to the appliance adapter with pipe seams oriented towards the wall
or oor, as much out of view as possible.
Place a bead of Mil-Pac on the
outer edge of the inner exhaust
pipe (non-ared end). Place a bead
of high temperature silicone on the
male edge of the outer pipe. Push
the pipe sections completely together,
then twist-lock one section clockwise
approximately  turn, until the two
sections are fully locked. The female
locking lugs will not be visible from the
outside, on black pipe. They may be
located by examining the inside of the
female ends as shown in Figure 8.
Notes:
(1) Twist-lock procedure: four indentations, located on the female end of the pipes and ttings, are designed to
slide straight onto the male ends of adjacent pipes and ttings, by orienting the four pipe indentations so they
match and slide into the four entry slots on the male end.
(2) Horizontal runs of vent pipe must be supported every three feet. Wall straps are available for this purpose, also
when running horizontal pipe minimum clearances to combustibles must be maintained; 2 inches (5.1 cm) at
top, 1 inches (3.8 cm) at sides, 1 inches (3.8 cm) at bottom.
STEP 3. With the pipe attached to the stove in the correct location, mark the wall for a 10” (25.4 cm) x 10” (25.4
cm) square hole (refer to Figure 9). The center of the square hole should match the centerline of the
horizontal pipe. Cut and frame the 10” (25.4 cm) x 10” (25.4 cm) hole in the exterior wall where the
vent will be terminated. Refer to Figure 8. If the wall being penetrated is constructed of non-combustible
material i.e. masonry or concrete, a 7 inches (17.8 cm) hole is acceptable.

of the sheet metal straps back towards the
vent cap, so the decorative wall thimble will
conceal it (see left image in Figure 10).
STEP 7. Slide the decorative wall thimble up to the
wall surface and attach with the screws
provided. Apply decorative brass or chrome
trim if desired (see right image in Figure 10).
NOTES:
(1) The four wood screws provided should be replaced
with the appropriate fasteners for stucco, brick,
concrete, or other types of siding.
(2) For buildings with vinyl siding, a vinyl siding
standoff, should be installed between the vent cap
and the exterior wall (see Figure 11). Attach the
vinyl siding standoff to the horizontal termination.
The vinyl siding standoff prevents excessive heat
from possibly melting the vinyl siding material.
Note that the horizontal vent termination bolts
onto the at portion of the vinyl siding standoff
(shaded area in Figure 11), so that an air space will
exist between the wall and the vent termination.
NOTES:
(1) The horizontal run of vent pipe must be level and
should have a  inch rise for every one foot
of run towards the termination. Never allow
the vent to run downward. This could cause high
temperature and may present the possibility of a
re.
(2) The location of the horizontal vent termination
on the exterior wall must not be easily blocked
or obstructed. Refer to “Initial Installation - Vent
Termination Restrictions” section.
(3) When installing a vent pipe in a chase the minimum
clearance to combustibles is 2” (5 cm).

STEP 4. Position the horizontal vent termination in the center of the 10” (25.4 cm) x 10” (25.4 cm) hole, and attach
to the exterior wall with the four screws provided. Before attaching the vent termination to the exterior
wall, run a bead of non-hardening mastic around the edges, so as to make a seal between the termination
and the wall. The arrow on the vent termination should be pointing up, insure that the proper clearances
to combustible materials are maintained.
STEP 5. Before connecting the horizontal run of the vent pipe to the vent termination, slide the black decorative
wall thimble cover over the vent pipe.
STEP 6. Slide the appliance and vent assembly towards the wall, carefully inserting the vent pipe into the cap
assembly. It is important that the vent pipe extend into the vent cap a sufcient distance with a minimum
of 1” (3.2 cm) overlap. Secure the connection between the vent cap pipe and the vent cap by attaching
the two sheet metal straps extending from the vent cap assembly into the outer wall of the vent pipe. Use
the two sheet metal screws provided to connect the straps to the vent pipe. Bend any remaining portion

STEP 2. Set the gas appliance in the desired location.
Drop a plumb bob down from the ceiling to the
position of the appliance ue exit, and mark
the location where the vent will penetrate the
ceiling. Drill a small hole at this point. Next,
drop a plumb bob from the roof to the hole
previously drilled in the ceiling, mark the
spot where the vent will penetrate the roof.
Determine if ceiling joists, roof rafters, or
other framing will obstruct the venting system.
You may wish to relocate the appliance, or to
offset, to avoid cutting load bearing members.
STEP 3. To install the Round Support Box/Wall Thimble
in a at ceiling, cut a 10 inch (25.4 cm) square
hole in the ceiling, centered in the hole drilled
in Step 2. Frame the hole as shown in Figure
14.
STEP 4. Assemble the desired lengths of black pipe and
elbows necessary to reach from the appliance
adapter up through the Round Support Box.
Insure that all pipe and elbow connections are
in their fully twist-locked position.
Do not interfere with the structural integrity
of the walls.

the exposed sections, bend
the support straps outwards,
and push the elbow strap
down to the roof level, as
shown in Figure 15. Tighten
the clamp around the pipe
section. Use a level to make
sure the pipe is truly vertical.
With roong nails, secure the
support straps to the roof.
Seal the nails holes heads
with non-hardening mastic.
Trim the excess length of the
support straps that extend
out beyond the edge of the
ashing.
STEP 7. Slip the ashing over the pipe
section protruding through
the roof. Secure the base
of the ashing to the roof
with roong nails. Use a
non-hardening sealant between the uphill edge
of the ashing and the roof. Insure the roong
material overlaps the top edge of the ashing as
shown in Figure 15. Verify that you have at least
the minimum clearance to combustibles at the
roof line.
STEP 5. Cut hole in the roof centered on the small hole placed in the roof from Step 2. The hole should be of
sufcient size to meet minimum requirements for Clearance to Combustibles, as specied. Continue to
assemble lengths of pipe and elbows necessary to reach from the ceiling support box up through the roof
line. Galvanized pipe and elbows may be utilized in the attic, as well as above the roof line. The galvanized
nish is desirable above the roof line, due to the higher corrosion resistance.
STEP 6. Once the pipe sections have been joined, and run up through the hole in the roof, slip an elbow strap over

STEP 8. Continue to add pipe sections until the height of the vent
cap meets the minimum code requirements. Refer to
Figure 16 and Table 3. Note that for steep roof pitches, the
vent height must be increased. In high wind conditions,
nearby trees, adjoining roof lines, steep pitched roofs,
and other similar factors can result in poor draft, or down
drafting. In these cases, increasing the vent height may
solve the problem.
STEP 9. Slip the storm collar over the pipe, and push it down to
the top of the roof ashing as shown in Figure 15. Use
the non-hardening sealant around the joint between the
pipe and the storm collar.
STEP 10. Twist-lock the vent cap.
NOTES:
(1) If an offset is necessary in the attic to avoid obstructions, it
is important to support the vent pipe every 3 feet (91 cm), to
avoid excessive stress on the elbows, and possible separation.
Wall straps are available for this purpose (see Figure 17).
(2) When ever possible, use 45° degree elbows instead of 90°
degree elbows. The 45° degree elbow offers less restriction to
the ow of ue gases and intake air.

STEP 1. Follow installation steps 1 & 2 under ‘Vertical Installation’.
STEP 2. Using the plumb bob, mark the centerline of the venting
system on the ceiling and drill a small hole through the
ceiling and roof at this point. From the roof, locate the drill
hole and mark the outline of the “Cathedral Ceiling Support
Box”.
STEP 3. Remove shingles or other roof coverings as necessary to
cut the rectangular hole for the “Support Box”. Cut the hole
” larger than the “Support Box” outline.
STEP 4. Lower the “Support Box” through the hole in the roof
until the bottom of the “Support Box” protrudes at least 2
inches (5 cm) below the ceiling. Align the “Support Box”
both vertically and horizontally with a level as shown in
Figure 19. Temporarily tack the “Support Box” in the place
through the inside walls and into the roof sheathing.
STEP 5. Using tin snips, cut the “Support Box” from the top corners
down to the roof line, and fold the resulting aps over the
roof sheathing (Figure 20). Before nailing it in to the roof,
run a bead of non-hardening mastic around the top edges
of the “Support Box”, to make a seal between the box and
the roof. Clean out any combustible material from the
inside of the “Support Box”.
STEP 6. Complete the cathedral ceiling installation by following the
same procedures outlined in Steps 4 through 9 for “Vertical
Installation”.

ADJUSTING THE VENTURIES:
• Remove the ash shelf by undoing the screw at each end, pull
shelf towards you.
• Remove one screw from the cover plate located below the
ash shelf. Loosen the other screw (do not remove) swing the
cover plate out of the way and tighten screw down to hold it in
place.
• With along screwdriver rotate spring clips to open or close the
shutter to the desired setting.
The venturies allows the amount of air coming into the replace to
be adjusted in order to accommodate different climates and venting
arrangements. Start the pilot and then the burner. Make sure the
pilot ame is burning normally and none of the burner ports are
plugged. Let the replace burn for roughly fteen minutes and
then examine the ames, compare the ames to Figure 37.
The ideal ame will be blue at the base and light orange above. The ames should be of medium height. If the
ames look like this, no venturi adjustment is needed. If the ames are fairly short and mostly blue, the replace
is getting too much air. Therefore, the venturies should be closed slightly until the correct ames are achieved.
Flames that are very orange, with tall, dark, stringy tips, are not getting enough air. Open the venturi until the
ames clean up. If the venturi is opened, or closed all the way, and the correct ames cannot be attained, turn off
the gas and contact the dealer.
Warning: Incorrect venturi adjustment may lead to improper combustion, which is a safety hazard. Contact the
dealer if there is any concern about the venturi adjustment.
