barrier (see Notice, Page 30)
This fireplace comes with a barrier to reduce the
likelihood of burns from touching hot glass. If
the barrier is damaged, the fireplace should be
turned off immediately and the fireplace must
not be operated until a new, approved factory
barrier for this unit is installed.
NOTE: It will be nexcessary to remove the barrier
filler trim piece. Upon reinstall, insure that the
tabs on the barrier filler are engaged with the
slots in the base of the fireplace.
To remove barrier follow these steps.
1. Lift barrier up by the frame at the top.
2. Remove lower filler piece by pulling down
off of the barrier.
3. Lower barrier and push barrier to left to
release right side.
4. Pull the right side out of fireplace.
5. Remove barrier.

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 37 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 local codes.
See Figure 37 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 glass door assembly on
the control side (see Page 31) and the access
plate (see Figure 38).
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
applications). Seal around gas line to prevent
cold air leakage. Use sealants approved by
local codes for the application.

GAS CONNECTION
NOTE: The gas supply line
must be installed in accor-
dance with building codes
by a qualified installer
approved and/or licensed
as required by the locality.
In the Commonwealth of
Massachusetts, installation
must be performed by a li-
censed plumber or gas fitter.

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 using a
gas leak test solution (also referred to as bubble
leak solution).
NOTE: Using a soapy water solution is an effec-
tive 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. See the lighting instruc-
tions label in the fireplace control compart-
ment or 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
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. Reinstall the access plate, making certain the
gasket has not been damaged.
