• in the case of a power outage it is possible to increase the output of the firebox by manually adjusting the
primary air control shutter. remove bottom cover from front of the furnace. gently pull
down on the vertical chain attached to servo motor, until it stops. latch the nearest
chain link into protruding chain lock finger, situated just above servo motor. this will
continuously maintain the maximum combustion air being fed into the fire box (furnace
must be monitored to prevent over firing). the burn rate can then be adjusted using the
air control lever located on the top front panel of the furnace. although the blower fan
will be inoperable in a power out situation, convection air flow through to the house will
move under gravity circulation.
• the air filter must be removed from the filter rack when operating in a power out
condition to help promote gravity circulation and prevent excessive heating of the duct
work.
• do not load firebox more than half full and never create a flash fire in a power outage.
• When electrical power returns, remove the draft control chain from the chain lock finger
for automatic draft control.

• control of the secondary heat source (electric) is done by a second thermostat located beside and at the
same height as the wood furnace thermostat. the thermostat for the electric furnace should be set 4°f
(2°c) to 5°f (3°c) below the setting for the wood thermostat. thus once the heat from the wood section
starts to decline, the corresponding decline in room temperature will cause the second thermostat to call
heat from the electric furnace. note that interlocks in the control system will force the secondary heat source
to shut down if the temperature in the supply plenum of the wood furnace exceeds the set value of the "high
limit" switch (250°f) (121°c).
THE ELECTRIC FURNACE HAs BOTH AUTOMATIC AND MANUAL REsET CONTROLs. THE MANUAL
REsET Is A FUsIBLE LINk AND sHOULD BE REpLACED BY A qUALIFIED INsTALLER/sERvICE
