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
“METALBESTOS MDV 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 FT (30.5 cm) to 3 FT (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.
If extra elbows are being used, overall allowable length will be reduced by 3 ft (91.5 cm) per
additional elbow.

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 rooine. 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.

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 7.
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. 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.

vent cap, so the decorative wall thimble will
conceal it (see left image in Figure 9).
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 9).
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 10). 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 10), 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” 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.

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
rooine. Galvanized pipe and elbows may be utilized in the attic, as well as above the rooine. The
galvanized nish is desirable above the rooine, 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.

oors (see Figure 14). The opening should be framed
to 10” (25.4 cm) x 10” (25.4 cm) inside dimensions,
in the same manner as shown in Figure 14.
(2) Any occupied areas above the rst oor, including
closets and storage spaces, which the vertical vent
passes through, must be enclosed. The enclosure
may be framed and sheetrocked with standard
building materials. However consult the appliance
manufactures installation instructions for the
minimum allowable clearance between the outside
of the vent pipe, and the combustible surfaces of the
enclosure. Do not ll any required air spaces with
insulation.

Installation.
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 rooine, 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”.
