CONNECtING GAS LINE Codes require a shut-off valve mounted in the
supply line. Figure 12 illustrates two methods
for connecting the gas supply. The flex-line
method is acceptable in the U.S., however,
Canadian requirements vary depending on
locality. Installation must be in compliance
with local codes.
These appliances are equipped with a gas flex
line for use (where permitted) in connecting the
unit to the gas line. A gas flex line is provided
to aid in attaching the direct vent appliance to
the gas supply. The gas flex line can only be
used where local codes permit. See Figure 12
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 under the
refractory cover in front of the burner.
To access the valve, lift out the center refrac-
tory and remove the access cover (see Figure
13 ).
The control valves have 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
applications).
Turn on gas supply and test for gas leaks, us-
ing a gas leak test solution (also referred to as
bubble leak solution). Note: Using a soapy
water solution (50% dish soap, 50% water)
is an effective leak test solution but it is not
recommended, because the soap residue that
is left on the pies/fittings can result in corro-
sion over time. Never use an open flame to
check for leaks.
A. Light the appliance (refer to the lighting
instructions label in the control compartment
or in the Homeowner's Care and Operation
Instructions).
B. Brush all joints and connections with the gas
leak test solution to check for leaks. If bubbles
are formed, or gas odor is detected, turn the
gas control knob to the “OFF” position. Either
tighten or refasten the leaking connection and
retest as described above.
C. When the gas lines are tested and leak free,
be sure to rinse off the leak testing solution.
