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 termina-
tion 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.

9. Install wall thimble
in the center of
the 10" square and
attach with wood
screws (Diagram 7).

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 appli-
ance in its desired
location. Drop a

tape
from the ceiling to

the position of the

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
framing will obstruct the venting system. You
may wish to relocate the appliance or to offset,
as shown in Diagram 2 to avoid cutting load
bearing members.
NOTE: For best results and optimum perfor-
mance 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 com-
bustibles of 1-1/2". 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.

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.

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).
