THERMOSTAT
WARNING: Do not con-
nect the thermostat to a power
source. Electrical shock and/or
a fire hazard will occur.
Light the fireplace as instructed in Lighting
Instructions on page 27. Set wall thermostat to
desired temperature.
This thermostat has been electronically cali-
brated at the factory and requires no adjust-
ment or leveling.
Upon installation, the thermostat must be al-
lowed to stabilize at room temperature for a
minimum of 30 minutes for proper operation.
To turn the fireplace off, adjust thermostat to
the lowest setting and turn the gas control knob
back to PILOT. The pilot will remain lit.
IMPORTANT: To turn the pilot off, turn the
gas control knob on the heater to the OFF
position.
OPERATING OPTIONAL
BLOWER ACCESSORY
Locate the blower controls by opening the lower
louver panel on the fireplace. Blower controls
are located on the right side of the switch
bracket to the left just inside the louver panel.
The BK manual blower and the BKT thermo-
statically-controlled blower have an ON setting
and an OFF setting. The blower will only run
when the switch is in the ON position. In the
OFF position, the blower will not operate.

Note for BKT Only: If you are using BKT
blower with optional thermostat (wall mounted
or remote control) for the fireplace, your fire-
place and 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 blow-
er will continue to run. The blower will shut off
after the firebox temperature decreases.
The blower helps distribute heated air from
the fireplace. Periodically check the louvers of
the firebox and remove any dust, dirt or other
obstructions that will hinder the flow of air.

INSPECTING bURNERS

Check pilot flame pattern and burner flame pat-
terns often.
PILOT ASSEMBLY
The pilot assembly is factory preset for the proper
flame height. Alterations may have occurred dur-
ing shipping and handling. Call a qualified service
person to readjust the pilot if necessary.
The height of the thermopile must be 3/8" to 1/2"
above the pilot flame as shown in Figure 48. The
thermocouple must be at a height of about 1/8"
above the pilot flame. The flame from the pilot
burner must extend beyond both the thermocouple
and thermopile.
If you pilot assembly does not meet these require-
ments:
• turn fireplace off (see To Turn Off Gas to Ap-
pliance, page 28)
• see Troubleshooting, page 33
