INSTALLATION
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 fl ex 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 fl ex connectors use only
approved fi ttings. Always provide a union so that
gas lines can be easily disconnected for servicing.
Flare nuts for copper lines and fl ex 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 fl ame for leak testing.

Diagram 3: The upper half of the fl ashing is in-
stalled under the roofi ng material and not nailed
down until the chimney is installed. This allows
for small adjustments.

TERMINATION
( MUST USE REDUCER
# 946-606 AND RIGID PIPE ADAPTOR
#770-994)
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 fl ue 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 fl oor
or ceiling of every level. To install the Firestop
spacer in a fl at ceiling or wall, cut a 10 inch square
hole. Frame the hole as shown in Diagram 2
and install the fi restop.
4) Assemble the desired lengths of pipe and
elbows. Ensure that all pipes and elbow con-
nections are in the fully twist-locked position
NOTE: For best results and optimum perform-
ance 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.
Silicone (red RTV) is optional.
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 suffi cient size to meet the minimum
requirements for clearance to combustibles
of 1-1/2". Slip the fl ashing under the shingles
(shingles should overlap half the fl ashing) as
per Diagram 3.
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 roofl ine
due to its higher corrosion resistance. Continue
to add pipe sections through the fl ashing until the
height of the vent cap meets the minimum height
requirements specifi ed 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 fl ashing to the roof with roofi ng 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.
