Turn the circuit breaker switch on the electric control
panel to the “on” position. fasten the controls cover
to the main electrical control panel using hex head
screws supplied with hmfk-ef10 kit.
mount the thermostat for the electric furnace beside the wood furnace thermostat. run 24v control wire to
the hmf100 and feed the wire back to the furnace. drill feed thru the hole into the panel beside location of
feed thru for wood thermostat control wires. install grommet into feed thru hole before pulling wires thru panel
(grommet should provide both abrasion protection and strain relief for the control wires).
connect control wires to terminals #3 and #4 of terminal strip (iv) (terminal strip mounted on furnace floor).
See wiring diagrams in Section 4.5.4, on page 20.
locate and fasten the blower division cover and the blower door onto the furnace and energize both 120v and
240v power sources at the resident disconnect.
NOTE
The electric furnace thermostat should be maintained approximately 3°f (-16°c) lower than the wood
thermostat, so if the wood furnace cannot maintain the required temperature the electric furnace will come
on when the room temperature drops.
CONNECT
HARNESS
connect the plastic harness connector of the supply
harness coming off the electrical control board to the
mating bulk head connector protruding thru the bot-
tom of the blower division bulk head.
