FBB4 VARIABLE SPEED BLOWER INSTALLATION
Attention: Install blower assembly before connecting gas inlet
supply line
NOTICE: Junction box on right side of fireplace must be pre-
wired at time of fireplace installation for use with blower

2. If applicable, turn OFF electric supply to fireplace.
3. Lower bottom louver on fireplace.

to complete wiring of junction box.
Attention: If installed, do not damage gas inlet supply line

Wiring
The appliance, when installed, must be electrically grounded in
accordance with local codes or, in the absence of local codes,
with the National Electrical Code, ANSI/NFPA 70, if an external
electrical source is utilized. This appliance is equipped with a
three-prong [grounding] plug for your protection against shock
hazard and should be plugged directly into a properly grounded
three-prong receptacle. Do not cut or remove the grounding prong
from this plug. For an ungrounded receptacle, an adapter, which
has two prongs and a wire for grounding, can be purchased,
plugged into the ungrounded receptacle and its wire connected
to the receptacle mounting screw. With this wire completing the
ground, the appliance cord plug can be plugged into the adapter
and be electrically grounded.
Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and dangerous
operation. Verify proper operation after servicing.
Blower Motor
The blower motor does not have oiling holes. Do not attempt to
oil the blower motor.
Blower Wheels
The blower wheels will collect lint and could require periodic
cleaning. If the air output decreases or the noise level increases,
it indicates a dirty blower wheel. Remove fan and clean blower
wheels.
Unplugging of blower accessory will not stop the heater
from cycling. To turn off gas to the heater (millivolt model):
push in gas control knob slightly and turn clockwise to
"OFF." Do not force. To turn off gas on direct ignition model,
turn gas line valve to "OFF."
