Step 5. REMOVE GLASS DOOR FRAME
Remove the glass door assembly. See Installa-
tion and Removal of Glass Door on Page 28.

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 36 illustrates two
methods for connecting the gas supply. A Sedi-
ment Trap is recommended to prevent moisture
and debris in gas 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 36 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 on the right
side of the unit.
When using solid gas line connector, access
the valve by removing the front door assembly
on the valve access side and the access plate
(see Figure 37).
The electronic control valve has a 3/8" (10 mm)
NPT thread gas supply inlet.
Bring the shutoff valve on the end of the flex-line
over to the hard pipe and tighten with wrenches
from above through the firebox opening.
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.

TEST ALL CONNECTIONS FOR GAS LEAKS
(FACTORY AND FIELD):
Never use an open flame to
check for leaks.
Turn on gas supply and test for gas leaks using a
gas leak test solution (also referred to as bubble
leak solution).
NOTE: Using a soapy water solution is an
effective leak test solution but it is not recom-
mended, because the soap residue that is left
on the pipes/fittings can result in corrosion
over time.

WARNING
NOTE: The gas supply line must
be installed in accordance
with building codes by a quali-
fied installer approved and/or
licensed as required by the
locality. In the Commonwealth
of Massachusetts, installation
must be performed by a licensed
plumber or gas fitter.

A. Light the appliance (refer to the lighting
instructions label in the control compartment
or in the Care and Operation Instructions
manual).
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
receiver or remote control to the "OFF" position.
Either tighten or refasten the leaking connection,
then retest as described above.
C. When the gas lines are tested and leak-free
be sure to rinse off the leak testing solution.
D. Re-install the access plate, making certain the
gasket has not been damaged.
Step 7. CHECKING APPLIANCE
OPERATION
Turn on burner then observe the individual
tongues of flame on the burner. Make sure all
ports are open and producing flame evenly
across the burner. If any ports are blocked, or
partially blocked, clean out the ports.
With gas line installed run initial system check-
out before closing up the front of the unit. Follow
the lighting instructions provided in the Care
and Operation Instructions manual.
NOTE: Lighting Instructions are also found on
the literature tag tied to the bracket above the
gas valve. To access the tag, reach into the
right side opening.
When first lighting the appliance, it will take a few
minutes for the line to purge itself of air. Once
purging is complete, the pilot and burner will
light and operate as indicated in the instruction
manual. Subsequent lighting of the appliance will
not require such purging. Inspect the pilot flame
(remove logs, if necessary, handling carefully).
Electronic Appliance Checkout
To light the burner, turn "ON" the optional remote
wall switch or turn the appliance mounted ON/
OFF switch to the "ON" position. Ensure the
igniter lights the pilot. The pilot flame should
engulf the flame sensor as shown in Figure 38.
