10.5 Manual or thermostat control
From factory, the opening and closing of the air inlet damper is manually activated by the
means of a switch located at the rear of the furnace. The switch has two positions; opened
and closed.
Position of the air control rod when the switch in
the “closed” position (-).
For added comfort, the installation of an optional wall thermostat is recommended since it
will open the air inlet damper when the room temperature is below the set point of the
thermostat and will close the air inlet damper as the desired temperature is reached (see
Appendix 1: Optional thermostat installation).
If the heat sensors detect any overheating in the air jacket of the furnace, the air inlet
damper will close automatically regardless of the type of control used.
The thermostat mode will work properly only if the air control damper switch is in
closed position.
10.6 Ash drawer
Your furnace is equipped with an ash drawer to collect ashes produced by the combustion
of wood. The ash drawer is provided with two (2) wing nuts to hold the door in a close
position. Operating the furnace with the ash drawer open may seriously damage the
furnace. The drawer must be emptied regularly.
