Step 6. CONNECT 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 35 illustrates
two methods for connecting the gas supply.
A Sediment 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. In-
stallation 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 35 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 control side and the access plate (refer
to Figure 34).
The electronic control valve has a 3/8" (10 mm)
NPT thread gas supply inlet.
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.
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.

TEST ALL CONNECTIONS FOR GAS LEAKS
(FACTORY AND FIELD):
WARNING
Never use an open flame to
check for leaks.
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 is an effective leak test solution
but it is not recommended, because the soap
residue that is left on the pipes/fittings can result
in corrosion over time.
A. Light the appliance (refer to the lighting
instructions label in 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" posi-
tion. 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. Reinstall the access plate, making certain
the gasket has not been damaged.

Step 7. INSTALL FIREBOX LINER
PANELS
Install the ceramic or porcelain liner panels
per the instructions provided in the kit.
NOTICE: Panel liners must be
installed before operating fireplace.
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
Step 8. VERIFY 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 pilot lighting instructions provided.
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 neces-
sary, handling carefully).
Appliance Checkout
To light the burner, refer to the lighting instruc-
tions in the Care and Operation Instructions
manual or the lighting label located behind right
panel. Ensure the igniter lights the pilot. The
pilot flame should engulf the flame sensor as
shown in Figure 36.
