OPERATING OPTIONAL

BLOWER ACCESSORY

Locate the blower controls by opening the lower louver panel on
the fireplace. Blower controls are located on the left side of the
switch bracket to the left just inside the louver panel.

The BK manual blower and the BKT thermostatically-con-
trolled 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 fireplace 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 blower 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.

OPERATING OPTIONAL GWMT1

WALL MOUNTED THERMOSTAT

Light the fireplace as instructed in 

Lighting Instructions

 on page

25. Set wall thermostat to desired temperature.

This thermostat has been electronically calibrated at the factory
and requires no adjustment or leveling.
Upon installation, the thermostat must be allowed 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.

 WARNING: Do not connect the thermostat to a power

source. Electrical shock and/or a fire hazard will occur.

INSPECTING BURNERS

Check pilot flame pattern and burner flame patterns often.

PILOT ASSEMBLY

The pilot assembly is factory preset for the proper flame height.
Alterations may have occurred during 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 54. 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 requirements:
• turn fireplace off (see 

To Turn Off Gas to Appliance

, page 24)

• see 

Troubleshooting

, pages 28 through 30

BURNER FLAME PATTERN

Burner flames will be steady; not lifting or floating. Flame patterns
will be different from unit to unit and will vary depending on
installation type and weather conditions.

If the vent configuration is installed incorrectly, the flames will lift
or "ghost". This can be dangerous. Inspect the flames after installa-
tion to ensure proper installation and performance.

Figure 55 shows a typical flame pattern.

If burner flame pattern differs from that described:
• turn fireplace off (see 

To Turn Off Gas to Appliance

, page 24)

• see 

Troubleshooting

, pages 28 through 30

The receiver continuously receives signals from the hand-
held remote to control the room temperature. If the hand-
held remote is misplaced, obstructed, or for any reason
cannot transmit to the receiver, the receiver will shut off
the fireplace after 8 minutes.

Key Pad Lock Feature

This feature allows the user to lock/unlock the keypad on the
hand-held remote in the MANU or AUTO mode to prevent
inadvertent operation (i.e. children operating the hand-held re-
mote control, etc.). The keypad is locked in either on or off. Press
the POWER and LOCK buttons together to turn the unit on or off.
