1) Maintain the 1-
1/4"(32mm) 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
the "Rigid Pipe Venting
Arrangements" section 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 fl ue
exit, and mark the location 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 framing
will obstruct the
venting system.
You may wish
to relocate the
appliance or to
offset, as shown i n
Diagram 2 t o
avoid cutting
load bearing members.
3) A Firestop spacer must be installed in the
fl oor or ceiling of every level. To install the
Firestop spacer in a fl at ceiling or wall, cut
a 10 inch (254mm) square hole. Frame the
hole as shown in Diagram 3 and install the
fi restop.
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 (0.9 meter), 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 roofl ine
due to its higher corrosion resistance. Continue
to add pipe sections through the fl ashing until
the height of the vent cap meets the minimum
height requirements specifi ed in Diagram 5 or
local codes. Note that for steep roof pitches,
the vertical height must be increased.

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: For best results and optimum
performance with each approved venting
system, it is highly recommended to apply
“Mill-Pac” sealant (supplied) to every in-
ner pipe connection. Failure to do so may
result in drafting or performance issues not
covered under warranty. Silicone (red RTV)
is optional.

9) Install wall thimble in the center of the 10"
(254mm) square and attach with wood
screws (Diagram 6).
Diagram 5
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
termination cap.
Note: If installing termination on a siding
covered wall, a vinyl siding standoff
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
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 suffi cient 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.

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 suffi cient size to meet
the minimum requirements for clearance
to combustibles of 1-1/4"(32mm). Slip the
fl ashing under the shingles (shingles should
overlap half the fl ashing) as per Diagram 4.
Diagram 4: The upper half of the fl ashing is
installed under the roofi ng material and not
nailed down until the chimney is installed.
This allows for small adjustments.
