Installation of Optional Equipment
BACK DRAFT DAMPER
OPTIONAL ACCESSORY PART # AMBD-12 Back Draft Damper
The Back Draft Damper may be installed in either a vertical or horizontal section of the
12" round hot air duct. It should be positioned as close to the plenum opening of the
Fire Chief as practical. Press the female end of the damper over the Fire Chief Furnace
collar or male end of the duct pipe. When properly positioned, the arrows on the air
flow decal point
"away"
from the Fire Chief Furnace.
NOTE
: The back draft damper may cause the blower to cycle on and off frequently. If
this occurs, install a sheet metal screw inside of the damper to prevent the flapper from
closing completely. This will allow the heat to rise off of the furnace.
