Step 6. CONNECTING GAS LINE
All codes require a shut-off valve mounted
in the supply line. The orientation of the
shut-off valve should face the front. Figure
39 illustrates two methods for connecting the
gas supply. A sediment trap is recommended
in the gas piping within the home to prevent
moisture and debris in the line from damaging
the valve.
The flex-line method is acceptable in the U.S.A.
where local codes permit, however, Canadian
requirements vary depending on locality. Instal-
lation must be in compliance with local codes.
These appliances are equipped with a gas flex
line for use in connecting the unit to the gas line.
See Figure 39 for flex line description. The
flex line is rated for both natural and propane
gas. A manual shut off valve is also provided
with the flex line.
The gas control valve is located in the lower
control compartment.
Access the valve compartment by removing the
lower control compartment panel (see Figure
40) by lifting and pulling the panel forward.
The panel is mounted on supporting tabs at
the extreme right and left hand sides. Engage
the tabs into the reliefs in the panel.
The millivolt and electronic control valve has a
3/8" (10 mm) NPT thread inlet port.
Secure all joints tightly using appropriate
tools and sealing compounds (ensure propane
resistant compounds are used in propane ap-
plications). It is recommended to seal around
the gas line to prevent cold air leakage.
These appliances come from the factory with
the gas line access plate removed to provide full
access to the end of the gas flex line.
As designed, the glass door needs to be opened
to access the open gas access area.
Acquire the shut-off valve and gas flex line and
pull the assembly forward, out of the compart-
ment. Separate the shut-off valve from the gas
flex line. Determine the length of pipe needed to
route the gas line form the last fitting to a point
directly below the access plate opening.
Using pipe-dressing materials appropriate for
the gas type, securely affix the shut-off valve
to this determined pipe length at a convenient
location outside of the appliance lower control
compartment.
Refer to Figure 41 and insert the last length
of gas pipe with its attached shut-off valve
into the lower control compartment, and pass
it through the gas line access hole on the left
side of the appliance outer wrapper.
Using appropriate materials for the gas type,
thread the last length of pipe into the end of the
gas vent run and tighten in place using a pipe
wrench external to the appliance between the
appliance outer wrapper and the framing.
GAS CONNECTION
Note: The gas supply line must be installed in accordance with building codes by a quali-
of Massachusetts, installation must be performed by a licensed plumber or gas fitter.
Figure 39
Important: Turn the last piece of gas pipe in
the last fitting until the shut-off valve is posi-
tioned in a way that allows the shut-off valve
handle to be accessed in the lower control
compartment, easily operated throughout its
full range of motion.
Bring the flex line to the shutoff valve by hand
and align the flare fittings. Tighten the fittings
by hand, and then use wrench to tighten com-
pletely, 1/4 turn at a time.
