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.

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.

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).
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. You
may wish to relocate the appliance or to offset,
as shown in Diagram 2 to avoid cutting load
bearing members.
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". 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.
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
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.
