WARNING: Never attempt to service heater while it is plugged in, oper-
ating, or hot. Burns and electrical shock could result. Only a qualified ser-
vice person should service or repair heater.
If any of the original wire as supplied with the appliance must be replaced, it must be
replaced with 105°C wire or it’s equivalent.
WARNING: Label all wires prior to disconnection when servicing con-
trols. Wiring errors can cause improper and dangerous operation. Verify
proper operation after servicing.
If any of the original wire as supplied with the appliance must be
replaced, it must be replaced with 105˚C wire or it's equivalent.
Operating the Blower
After final installation of your fireplace, light your gas appliance
with the blower off. After about 15 minutes, turn the blower on to
deliver heated air at the top louvers. The blower features a variable
control which allows you to select the speed you desire. In the OFF
position, the blower will not operate. In the ON position, the
blower will start when the thermostat senses a sufficient increase
in firebox temperature (approximately 10 to 20 minutes depend-
ing on heat setting).
Your gas logs and thermostat blower will not turn on and off at the
same time. The fireplace may run for several minutes before the
blower turns on. After the heater modulates to the pilot position, the
blower will continue to run. The blower will shut off after the
firebox temperature decreases.
It is safe to operate fireplace with blower turned off. However, the
blower helps distribute heated air from the fireplace.
Note:
Periodically check the louvers of the firebox and remove any
dust, dirt, or other obstructions.
WARNING: A qualified service person must con-
nect fireplace to gas supply. Follow all local codes.
WARNING: For natural gas units, never connect
fireplace to private (non-utility) gas wells. This gas is
commonly known as wellhead gas.
INSTALLING GAS PIPING TO FIREPLACE
LOCATION
WARNING: For propane/LP units, never connect
fireplace directly to propane/LP supply. This fire-
place requires an external regulator (not supplied).
Install the external regulator between the heater and
propane/LP supply.
WARNING: Failure to position the parts in accor-
dance with supplied diagrams or failure to use only
parts specifically approved with this heater may result
in damage or personal injury.
WARNING: A qualified service person must con-
nect fireplace to gas supply. Follow all local codes.
15. If gas connections have been made and checked, replace fireplace
floor assembly in fireplace. Feed flexible gas supply line into fire-
place base area while replacing fireplace floor assembly. Make sure
the entire flexible gas line is in fireplace base area.
IMPORTANT:
Do not pick up fireplace floor assembly by burners. This could
damage burners. Only handle base by grates.
Note:
Be careful of
all wires and components on underside of floor assembly.
16. Reattach fireplace floor assembly with screws removed in step
3 of Removing Fireplace Screen and Floor Assembly, page 8.
Note:
Discard the remaining hardware items. After assembly,
make sure all wires are completely clear of blower wheel.
17. Install logs (see Installing Logs, pages 21 through 23) and fire-
place screen (see Installing Screen, page 24).
