NOTICE
IMPORTANT:

This furnace must be installed according to CSA Standard B365 “Installation Code for Solid-Fuel
Burning Appliances and Equipment”.

The solid fuel side of this furnace is designed to burn wood only, unless equipped with grates thus
allowing the burning of coal. Burn anthracite coal only.
 Proper flue draft must be maintained to allow combustion gases to flow freely out the chimney.
FOR SAFE OPERATION:
 Load fuel carefully or damage may result.

Do not load solid fuel higher than the fire box liner.
 Do not use chemical or fluid fire starters.

Do not attempt to light a fire when there is oil vapour present.

Minimum flue draft - .03” W.C.

Maximum flue draft - .05” W.C.

Do not burn garbage, manufactured fire logs, gasoline, naptha or crankcase oil.
 Keep the furnace doors tightly closed except for refueling and cleaning.

To maintain furnace efficiency and prevent soot fires, clean the heat exchanger, flue pipes, and
chimney at the end of each heating season and as frequently as required during the heating season to
prevent soot accumulation. The furnace and flue must be in good condition. Turn off power to the
furnace when cleaning the furnace and flue.

Do not store fuel or combustible material within the furnace clearances.

Do not use salt wood (driftwood gathered from the seashore).
TO PREVENT DAMAGE
:

Do not set the flue draft above - .05” W.C.

Do not open the furnace door slide plate damper during normal operation.

Furnaces with grates must have ashes removed daily.

Furnaces without grates require a minimum of 2” of sand or wood ash in bottom of firebox.
SPECIAL PROCEDURES
POWER FAILURE
:
1. Remove the blower access door and air filters for better air circulation. If the furnace is in an enclosed
area (furnace room) open the door to the room.
2. To control the fire, open the slide plate damper in the furnace door. THIS DAMPER SHOULD BE
CLOSED FOR NORMAL OPERATION.
3. Do not load the firebox higher than half way up the fire box liner.
SOOT FIRE
Close all sources of air that can reach the fire through the furnace and draft regulator. Insure the draft fan
above the fire door is turned off. Do not attempt to take the flue pipes down until the fire has been
completely extinguished.
RUNAWAY FIRE
This can be caused by too high a flue draft or excessive fueling.
1. Close all sources of air to the furnace. Insure draft fan is turned off.
2. Set the barometric draft regulator wide open to reduce draft. The excessive heat caused by a runaway
fire may damage the furnace safety controls. Their operation should be checked before the furnace is
returned to service. After a soot or runaway fire inspect chimney connection and chimney.
MINIMUM INSTALLATION CLEARANCES FROM COMBUSTIBLE MATERIAL
Fire door end 48”
One side 6”
Other side (walkway) 24”
Blower door end 30”
Flue Pipe 18”
Plenum and takeoff ducts to 6’ from furnace 6”
Duct beyond 6’ from furnace 1/2”
Floor non-combustible
