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
