6) Continue to assemble pipe lengths.
Note: If an offset is necessary in the attic
to avoid obstructions, it is impor-
tant to support the vent pipe every
3 feet (0.9 meter), to avoid exces-
sive 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 in-
creased.

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.

Note:
Apply sealant
"Mill-Pac" to in-
ner pipe and
high temp sili-
cone sealant to
outer pipe on
every twist-
lock joint.

9) Install wall thimble in the center of the 10"
(254mm) square and attach with wood
screws (Diagram 6).

6) The arrow on the vent cap should be
pointing up. Insure that the 1-1/4"(32mm)
clearances to combustible materials are
maintained (Diagram 5). Install the termina-
tion cap.
Note: If installing termination on a siding
covered wall, a vinyl siding stand-
off or furring strips must be used
to ensure that the termination is
not recessed into the siding.
The four wood screws provided should be
replaced with appropriate fasteners for
stucco, brick, concrete, or other types of
sidings.
7) Before connecting the horizontal run of
vent pipe to the vent termination, slide the
Wall Thimble (Part # 942) over the vent pipe.
8) Slide the appliance and vent assembly to-
wards the wall carefully inserting the vent
pipe into the vent cap assembly. It is impor-
tant 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
(32mm). 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"(32mm) clear-
ances (air spaces) to com-
bustibles when passing
through ceilings, walls, roofs,
enclosures, attic rafter, or oth-
er nearby combustible surfac-
es. Do not pack air spaces
with insulation. Check pages
13-18 for the maximum verti-
cal rise of the venting system
and the maximum horizontal
offset limitations.
2) Set the gas appliance in its
desired location. Drop a plumb
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 (254mm) square hole. Frame the
hole as shown in Diagram 3 and install the
firestop.
bob down from the
ceiling to the position
of the appliance flue
exit, and mark the loca-
tion 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
joists, roof rafters or other fram-
ing will obstruct the venting sys-
tem. You may wish
to relocate the ap-
pliance or to off-
set, as shown in
Diagram 2 to avoid
cutting load bear-
ing members.
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 1-1/4"(32mm). Slip the
flashing under the shingles (shingles should
overlap half the flashing) as per Diagram 4.
Diagram 4: The upper half of the flashing is
installed under the roofing material and not
nailed down until the chimney is installed.
This allows for small adjustments.
