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 right just inside the louver panel.
The BK manual blower and the BKT thermo-
statically-controlled 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 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.

INSPECTING bURNERS

Check pilot flame pattern and burner flame pat-
terns often.
PILOT ASSEMBLY
The pilot assembly is factory preset for the proper
flame. Alterations may have occurred during ship-
ping and handling. The pilot is located on the left
hand side of the burner.
116237-01E
The flame must envelope 1/4" of top of the ignitor/
sensor and grounding stem.
If your pilot assembly does not meet these re-
quirements:
• Turn the adjustment screw marked PILOT
clockwise to decrease or counterclockwise to
increase the flame to proper size (see Figure 42,
page 28). Do not remove the adjustment screw.

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 45 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 28)
• see Troubleshooting, page 31
