Overfiring — Caution!
Overfiring of your woodburning appliance represents a serious fire hazard.
Overfiring can also warp your stove, break welds, permanently discolour the
enamel and cause premature burnout of your stove. Repeated overfirings will
void the warranty of this appliance.
To prevent overfiring:
1. If the air intake has little effect on dampering the fire, excessive chimney draft is
the probable cause (especially on chimneys in excess of 20’). Normal chimney
draft is approximately 0.05" W.C. NOTE: Open damper before opening door
to prevent smoking.
2. Install a magnetic thermometer on the top of your stove near the flue collar or
a probe-type thermometer in the smoke pipe.
To prevent creosote buildup in the pipes, the stove should be run between
800°F and 900°F for 30-45 minutes each burning day.
3. Except for the initial period after lighting (5-10 minutes), do not operate your
stove with the door open.
4. Ensure the ash pan door is tightly closed during operation. An open ash pan door
will allow excess draft through the firebox, causing overfiring. When emptying
ashes, clean thoroughly behind the ash pan to allow complete closure.
5. Clean your chimney regularly to remove creosote buildup. A chimney fire is a
fire hazard and will overfire your stove. See page 20, "What to do if you have
a chimney fire"
6. During operation, if any parts of the stove or pipe begin to glow the stove is
overfired. Do not add fuel. Close all doors, dampers and draft controls completely
until glowing is eliminated and safe temperatures are restored. If overfiring
conditions persist on subsequent burnings, contact your dealer for remedial
action.
