Blower controls are located on the left side ofthe switch bracket to the right just inside the louver panel.The BK manual blower and the BKT thermostatically-controlledblower have an ON setting and an OFF setting. The blowerwill only run when the switch is in the ON position. In the OFFposition, the blower will not operate.Note for BKT Only: If you are using BKT blower with optionalthermostat (wall mounted or remote control) for the fireplace,your fireplace and blower will not turn on and off at the sametime. The fireplace may run for several minutes before the blowerturns on. After the heater modulates to the pilot position, theblower will continue to run. The blower will shut off after thefirebox 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.BURNER FLAME PATTERNBurner flames will be steady; not lifting or floating. Flame patternswill 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 liftor "ghost". This can be dangerous. Inspect the flames after instal-lation to ensure proper installation and performance.Figure 45 shows a typical flame pattern.If burner flame pattern differs from that described:• turn fireplace off (see To Turn Off Gas to Appliance)• see Troubleshooting, page 26Figure 45 - Typical Flame PatternPilot BurnerIgnitor/SensorINSPECTING BURNERSCheck pilot flame pattern and burner flame patterns often.PILOT ASSEMBLYThe pilot assembly is factory preset for the proper flame. Altera-tions may have occurred during shipping and handling. The pilotis located on the left hand side of the burner.The flame must envelope 1/4" of top of the ignitor/sensor andgrounding stem.If your pilot assembly does not meet these requirements:• Turn the adjustment screw marked PILOT clockwise to decreaseor counterclockwise to increase the flame to proper size (seeFigure 42, page 23). Do not remove the adjustment screw.• see Troubleshooting, page 26Figure 44 - Correct Pilot Flame PatternSensing RodOPERATING FIREPLACEContinued
