Installation of Optional Equipment
Back Draft Damper
OPTIONAL ACCESSORY PART # AMBD-8 Back Draft Damper
The Back Draft Damper may be installed in either a vertical or horizontal section of the
8" round hot air duct. It should be positioned as close to the plenum opening of the
FC300 as practical. Press the female end of the damper over the FC300 furnace collar or
male end of the duct pipe. When properly positioned, the arrows on the air flow decal
point
"away"
from the FC300.
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 heat to rise off of the furnace.
Installing Hot Water Coil
OPTIONAL ACCESSORY PART #TB-24S Water Coil with Hole Saw
1. Drill two, one inch holes at the rear of the furnace just above the firebrick inside of
the firebox using the template and hole saw provided in the Water Coil Kit.
2. Place one nut on each end of the water coil and thread each as far as they will go.
3. Open the loading door and insert the coil through the holes at the end of the firebox.
4. From the rear of the furnace, thread on the remaining two nuts and tighten securely.
5. Have a qualified plumber connect your domestic hot water pipe to the coil
with the appropriate fittings.
