BLOWER ACCESSORY
Locate blower controls by opening lower
louver panel on fireplace. Blower controls are
located on the right side of switch bracket to
the left just inside louver panel.
The BK manual blower and BKT thermostati-
cally-controlled blower have an ON setting
and an OFF setting. Blower will only run when
switch is in the ON position. In the OFF posi-
tion, blower will not operate.
Note for BKT Only: If you are using BKT
blower with optional thermostat (wall mounted
or remote control) for fireplace, your fireplace
and blower will not turn on and off at the same
time. Fireplace may run for several minutes
before blower turns on. After heater modulates
to the pilot position, blower will continue to run.
Blower will shut off after firebox temperature
decreases.
The blower helps distribute heated air from the
fireplace. Periodically check louvers of firebox
and remove any dust, dirt or other obstruc-
tions that will hinder the flow of air.
