Control of the secondary heat source (either electric or oil) is done by a combination of a selector switch
on the main furnace control panel and a second thermostat located beside and at the same height as the
wood furnace thermostat. The selector toggle switch needs to be switched to the appropriate back up
furnace installed (can be switched to either oil or electric depending on energy rates if both backups are
installed). The thermostat for the back up heat source should be set 4°f to 5°f (2°C to 3°C) below the
setting for the wood thermostat. Thus once the heat from the wood section starts to decline, the corre-
sponding decline in room temperature will cause the second thermostat to call heat from the secondary
heat source. 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).
NoTE
The control of the "add on" style installation is the same as the fore mentioned paragraph except for the
position of the selector toggle switch being redundant.

a summer fan switch has been added to the main electric control box. This will provide low speed air
circulation during the summer time when the furnace is not being used. depress rocker switch to “Summer
fan” position, the switch will light and the fan will run.
expansion / contraction noises during heating up and cooling down cycles are normal and to be expected.
When first installed, the furnace brick and metal are cold and must become hot before the appliance will func
-
tion well. During the break-in period (the first 2 or 3 fires) create only small, hot fires using kindling; this will
allow the firebrick to cure. Do not be alarmed if small hairline cracks develop in the firebrick. This is a normal
occurrence and does not pose a safety hazard. The paint may also smell a little for the first few fires as it
cures and you may wish to open a door or window to alleviate the smell.
There are many different ways to start a fire, review the hints and warnings in this section to ensure the fire is
started properly.
