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 CAN/CGA B149 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.

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.

1. Maintain the 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 ver-
tical 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 previ-
ously 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 11 inch square hole. Frame the hole as
shown in Diagram 2 and install the firestop.
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 connec-
tion. Failure to do so may result in drafting
or performance issues not covered under
warranty.
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 2". Slip the flashing under
the shingles (shingles should overlap half
the flashing) as per Diagram 63.
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.
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 requirements specified in Dia.64 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.
Note: All vertical terminations are vent-
ed using 5" x 8" venting and rigid pipe
adaptor #770-994.
* Clearances noted below must be maintained;
except when passing through a wall, ceiling or at
the termination where the use of a firestop or wall
thimble reduces clearance to 1-1/2" (38mm).
