Wall Mounted Thermostat
WARNING: Do not connect 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 23. 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.

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 forseveral 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. Peri- odically 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 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 23)
•see Troubleshooting, page 27

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 instal- lation 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 instal- lation to ensure proper installation and performance.
Figure 55 shows a typical flame pattern for these models. If burner flame pattern differs from that described:
•turn fireplace off (see To Turn Off Gas to Appliance, page 23)
•see Troubleshooting, page 27
