OPERATIng fireplace

Continued

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.

If you pilot assembly does not meet these require- ments:

•turn fireplace off (see To Turn Off Gas to Ap- pliance, page 32 or 35 depending on model)

•see Troubleshooting, page 38

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 position and pattern of the pilot flames in rela- tion to the sensing devices should be as shown in Figures 66 and 67 depending on model.

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 danger- ous. Inspect the flames after installation to ensure proper installation and performance.

Figure 68 shows a typical flame pattern.

If burner flame pattern differs from that de- scribed:

•turn fireplace off (see To Turn Off Gas to Ap- pliance, page 32 or 35 depending on model)

•see Troubleshooting, page 38
