OPERATING OPTIONAL
BLOWER ACCESSORY
Locate the blower controls by opening the lower louver panel on
the fireplace. Blower controls are located on the left side of the
switch bracket to the left just inside the louver panel.
The BK manual blower and the BKT thermostatically-con-
trolled blower have an ON setting and an OFF setting. The
blower will only run when the switch is in the ON position. In the
OFF position, the blower will not operate.
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 for several 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.
Periodically check the louvers of the firebox and remove any
dust, dirt, or other obstructions that will hinder the flow of air.
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 52 shows a typical flame pattern.
If burner flame pattern differs from that described:
• turn fireplace off (see To Turn Off Gas to Appliance, page 25)
• see Troubleshooting, pages 28 and 29

INSPECTING BURNERS
Check pilot flame pattern and burner flame patterns often.
PILOT ASSEMBLY
The pilot assembly is factory preset for the proper flame. Alterations
may have occurred during shipping and handling. The pilot is
located on the back right hand side of the burner.
The flame must envelope 1/4" of top of the ignitor/sensor and
grounding stem.
If your pilot assembly does not meet these requirements:
• Turn the adjustment screw marked PILOT clockwise to decrease
or counterclockwise to increase the flame to proper size (see
Figure 49, page 25). Do not remove the adjustment screw.
• see Troubleshooting, pages 28 and 29
