SCOTSMAN WOOD FURNACE – INSTRUCTION MANUAL
Scotsman Oct-06 17
M847 – Damper Motor
The damper door lever should be attached to the damper motor wheel with the chain
included. Be sure the damper door is fully closed and the damper motor is not
powered. Connect the chain to the damper door level and to the bottom hole in the
damper motor wheel. As a final adjustment bend the top chain link slightly to vary the
damper position.
L4064R – Wood Furnace/Limit Control
The fan and limit control mounted in the plenum controls the operation of the circulating
blower and limits the air temperature to prevent the furnace from overheating.
Set Points
1) “ON” is usually set to 140 ? F (60°C). It turns on the circulating blower when the air
temperature in the plenum reaches this temperature.
2) “OFF” is usually set to 100°F (38°C). It turns off the circulating blower when the
circulating air temperature in the plenum drops to this temperature.
3) “Hi limit” is preset to 280°F (138°C). This will over ride the room thermostat to
close fire damper door if the wood furnace overheats.
