4. OPERATING INSTRUCTIONS
Control system
On the wood furnaces only, the thermostat controls the air inlet damper. When the thermostat calls for heat, the
damper opens and the fire burns up. When the furnace gets hot enough, the combined limit control activates the
blower motor at the speed selected for wood heating.
The chain that links the air inlet damper to the motor must have a play of 1/8 inch. When there is no call for heat,
the air inlet damper must be completely closed and the chain must be affixed to the servo-motor at “8 o’clock”.

LIGHTING:
1. Open the door
Note: In the case that there is a bed of coals in the bottom of the furnace, go to step b) Pre-heating.
2. Place one or two dry kindlings at the front of the furnace.
3. Place newspaper strips on top of the kindlings.
4. Cover the newspaper with more kindlings and small pieces of dry wood.
5. Add newspaper strips, then light the fire a low as possible and leave the door 1/2" (13 mm) opened. If you fail
lighting the fire, you might experience a back draft through the air inlets.
PREHEATING
1. Once the kindling is well ignited or the coals revived, put 2 or 3 fire logs in such a way that the flames can interlace
between the logs then close the door. It is important to respect these loading sequences so that the wood will burn
from the front to the back of the furnace.
2. Wait 15 to 20 minutes, then proceed with loading the furnace.
