The BK manual blower and BKT thermostatically
Note for BKT Only: If you are using BKT blower with optional thermostat (wall mounted or remote control) for fireplace, your fireplace and blower will not turn on and off at the same time. Fireplace may run for several minutes before blower turns on. After heater modulates to the pilot position, blower will continue to run. Blower will shut off after firebox temperature decreases.
The blower helps distribute heated air from the fireplace. Periodically check louvers of 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 thermopile must be 3/8" to 1/2" above pilot flame as shown in Figure 49. The thermocouple must be at a height of about 1/8" above pilot flame. Flame from pilot burner must extend beyond both thermocouple and thermopile.
