Burner Flame Pattern
The position and pattern of the pilot flames in relation to the sens- ing devices should be as shown in Figures 64 and 65 respectively.
The pilot flame may need adjustment in order for the thermocou- ple, thermopile and/or the ignition system to sense the pilot flame.
If your pilot assembly does not meet these requirements:
•turn fireplace off (see To Turn Off Gas toAppliance, page 26 or 27)
•see sections under Troubleshooting, pages 31 through 35

BLOWER ACCESSORY
Blower control is located on the ignitor bracket to the right of the gas control behind the lower louver panel.
The BK manual blower and the BKT thermostatically con- trolled blower have a control knob to turn on the blower and adjust the fan speed. Rotating the knob approximately 1/4 turn will switch the blower ON in the high position. Turning the knobfurtherwillreducetheblowerspeedtothelowestposition. To turn the blower off, rotate the knob back until it clicks off.
Note for BKT Only: If you are using a BKT blower, the blower will not turn on until the fireplace has been burning for several minutes and is sufficeintly heating. The blower control works independent of the gas control, wall mounted switch or remote control s. For the BKT blower to operate automatically the speed control knob must be left in the on position prior to turning on the fireplace either manually or remotely.
The blower helps distribute heated air from the fireplace. Periodically check the louver of the fireplace 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.

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 dangerous. Inspect the flames after installa- tion to ensure proper installation and performance.
Figure 66 shows a typical flame pattern.
If burner flame pattern differs from that described:
•turn fireplace off (see To Turn Off Gas to Appliance, page 26 or 27)
•see Troubleshooting, pages 31 through 35
