Furnace Operation

SAFETY

WARNING: If this furnace is not properly installed, a house
fire may result. For your safety, follow the installation
directions. Contact local building or fire officials about
restrictions and installation requirements in your area.
NOTE: We strongly recommend installers to be WETT or
WHERF certified.
To ANYONE using this furnace:
These DO's and DO NOT's are for your safety.
1. DO read this instruction manual before lighting your first
fire.
2. DO burn seasoned wood fuel only. DO NOT burn:
- driftwood (salt corrosion is not a warranty item)
- treated wood
- coal
- garbage
- plastic
Also DO NOT use construction scraps (e.g., 2x4 or plywood
scraps) as your only supply of fuel, as you may overheat and
seriously damage the furnace.

3. DO NOT use gasoline type lantern fuel, kerosene, charcoal
lighter fluid or similar liquids to start or freshen up the fire in
this furnace. Keep all such liquids well away from the furnace
while it is in use.
4. DO keep the furnace door shut at all times when a fire is
burning. Open the door only to load or check the fire.
5. When checking or loading wood into the fire, DO pull open
the bypass lever first, then open the door very slowly.
6. DO keep all combustible materials (firewood, shoes etc.) at
least 18 inches away from the furnace.
7. Do not use a grate or elevate the fire.

CREOSOTE

When wood is burned slowly, it produces tar and other
organic vapours, which combine with expelled moisture to
form creosote. The creosote vapours condense in the rela-
tively cool chimney flue of a slow burning fire. As a result,
creosote residue accumulates in the flue lining. When ignited,
this creosote makes an extremely hot fire.
A chimney fire occurs when creosote in the chimney
ignites, usually when the furnace is turned up high after a
period of low burn.
