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. 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.

the center of the 10"
square and attach
with wood screws
(Diagram 7).

Unit Installation with Vertical
Termination
1. Maintain the 1-1/4" 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
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.

NOTE:
For best results and optimum
performance with each approved venting
system, it is highly recommended to apply
"Mill-Pac" sealant (supplied) to every inner
pipe connection. Failure to do so may result
in drafting or performance issues not covered
under warranty.
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 con-
nections 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". Slip the flashing under the shingles
(shingles should overlap half the flashing) as
per Diagram 4.
Diagram 1
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.
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, 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
