The four wood screws provided should
be replaced with appropriate fasteners for
stucco, brick, concrete, or other types of
sidings.
Note: If installing termination on a sid-
ing covered wall, a vinyl siding
standoff or furring strips must
be used to ensure that the ter-
mination is not recessed into the
siding.
7. Before connecting the horizontal run of vent
pipe to the vent termination, slide the Wall
Thimble over the vent pipe.
8. Slide the appliance and vent assembly
towards the wall carefully inserting the
vent pipe into the vent cap assembly. It is
important that the vent pipe extends into the
vent cap sufficient distance so as to result
in a minimum pipe overlap of 1-1/4 inches
(32 mm). Secure the connection between
the vent pipe and the vent cap by attaching
the two sheet metal strips extending from
the vent cap assembly into the outer wall
of the vent pipe. Use the two sheet metal

screws provided to
connect the strips
to the pipe section.
See Diagram 6.

1. Maintain the 1-1/4" (32 mm)
clearances (air spaces) to
combustibles when passing
through ceilings, walls, roofs,
enclosures, attic rafter, or
other nearby combustible
surfaces. Do not pack air
spaces with insulation. Check
for the maximum vertical rise
of the venting system and
the maximum horizontal
offset limitations.
2. Set the gas appliance in
its desired location. Drop
a plumb bob down from
the ceiling to the position
of the appliance flue exit, and mark the
location Diagram 1
where the vent will penetrate the ceiling.
Drill a small hole at his point. Next, drop
a plumb bob from the roof to the hole
previously drilled in the ceiling, and mark
the spot where the vent will penetrate
the roof. Determine if ceiling

3. A Firestop spacer must be installed in the
floor or ceiling of every level. To install the
Firestop spacer in a flat ceiling or wall, cut
a 10 inch square hole. Frame the hole as

shown in Diagram 3 and install the firestop.
4. Assemble the desired lengths of pipe and
elbows. Ensure that all pipes and elbow
connections are in the fully twist-locked
position and sealed.
5. Cut a hole in the roof centered on the small
drilled hole placed in the roof in Step 2. The
hole should be of sufficient size to meet
the minimum requirements for clearance
to combustibles of 1-1/2" (38 mm). Slip the
flashing under the shingles (shingles should

This allows for small adjustments.
overlap half the flashing) as per Diagram 4.
6. Continue to assemble pipe lengths.
Note: If an offset is necessary in the attic
to avoid obstructions, it is important
to support the vent pipe every 3 feet
(0.91m), to avoid excessive stress on
the elbows, and possible separation.
Wall straps are available for this
purpose (Diagram 2).
Galvanized pipe is desirable above the roof line
due to its higher corrosion resistance. Continue

to add pipe sections through the flashing until
the height of the vent cap meets the minimum
height requirements specified in Diagram 5 or
local codes. Note that for steep roof pitches,
the vertical height must be increased.
