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 3 sheet metal
screws.
9) Install wall thimble in the center of the 10"
square and attach with wood screws (Diagram
4).

Termination
1) Maintain the 1-1/2" 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 "Venting"
Sections 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 this 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.
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 2 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 3.
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.
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 3: 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.
Galvanized pipe is desirable above the roofline
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
Diagram 1
requirements specified in Dia. 4 or local codes.
Note that for steep roof pitches, the vertical
height must be increased. A poor draft, or down
drafting can result from high wind conditions
near big trees or adjoining roof lines, in these
cases, increasing the vent height may solve the
problem.
7) Ensure vent is vertical and secure the base of
the flashing to the roof with roofing rails, slide
storm collar over the pipe section and seal with
a mastic.
8) Install the vertical termination cap by twist-
locking it.

Note: Any closets or storage spaces,
which the vent passes through
must be enclosed.
Gas Line
Installation
The gas line is brought through the right side of
the appliance. The gas valve is situated on the
right hand side of the unit and the gas inlet is on
the right hand side of the valve.
The gas line connection may be made of rigid pipe,
copper pipe or an approved flex connector. (If you
are using rigid pipe, ensure that the valve can be
removed for servicing.) Since some municipalities
have additional local codes it is always best to
consult with your local authorities and the CSA
B149.1 installation code.
For USA installations follow local codes and/or
the current National Fuel Gas Code, ANSI Z223.1.
When using copper or flex connectors use only
approved fittings. Always provide a union so that
gas lines can be easily disconnected for servicing.
Flare nuts for copper lines and flex connectors
are usually considered to meet this requirement.
Important: Always check for gas leaks with a
soap and water solution or gas leak detector.
Do not use open flame for leak testing.
