GENERAL INFORMATION
BLOWER KITS
FBK-100 AND FBK-200
These blower kits may be used with various models of fireplaces. The
FBK-100 blower kit is used when wall-mounted ON/OFF blower switch
is desired, and the FBK-200 when wall-mounted variable speed blower
control is desired. The blower is installed beneath the firebox. Room air
is drawn in through the bottom area of the fireplace, heated as it passes
across the firebox, and discharged through the upper panel/louver area
at the top of the fireplace. Kit FBK-100 contains one blower, two Velcro
strips and these instructions. Kit FBK-200 contains one blower, one
speed control switch, two Velcro strips and these instructions.
Note: Velcro strips are for use in Step 6 D on page 2 only.
