BLOWER INSTALLATION
Remove the 2 screws from the receptacle cover plate on the lower right side of the firebox. Insert the supplied
receptacle into the slot with the receptacle facing the inside of the firebox. Replace the cover plate leaving the
Black, White & Green (ground) wires through the access hole in the cover plate for wiring.
Remove the fan cover plate from inside your firebox by removing screws as illustrated below.
Once the fan cover plate is removed you will be able to access the 2 wires connected to the therm-O-Disc.
Using 2 wire nuts connect the therm-O-Disc wires to the 2 receptacle wires and then tuck these wires out of
the way of the blower.
Install the HFB-BB blower assembly by first plugging power cord into receptacle located to the right under
the hearth pan. Using the same ten screws, secure blower cover plate to the hearth pan.
Blower operates thermostatically when the gas logs are in operation.
NOTICE: Blower motor is permanently lubricated; it does not require oiling.
Remove ten screws from existing cover plate.
