Emergency Procedure
Soot or Chimney Fire
1. Close damper door by unhooking chain.
2. Close fire door.
3. Do not remove flue pipe before fire is completely out.
4. Call the fire department.
Run-A-Way Fire
1. Close damper door by unlocking chain.
2. Close fire door.
3. Close off all air from entering the firebox.
4. Fully open barometric damper to reduce draft.
Power Failure
1. Close damper door by unhooking chain.
2. Close fire door.
3. Remove lower side panel to allow air circulation.
3. Open all air registers fully and furnace room door to
give better circulation.
NOTE: This furnace is designed for limited operation dur-
ing a power failure using gravity circulation. See “Gravity
Firing Instruction”.
DO NOT CHARGE FIRE BOX HIGHER THAN ONE
QUARTER OF THE WAY UP THE FIRE DOOR UN-
DER GRAVITY FIRING OPERATION.
Creosote - Important Woodburning Information
Creosote is the tar-like substance that forms on the heat
exchanger, flue pipe and chimney when burning wood.
Wood combustion is never complete, a visible sign is
smoke coming from your chimney.
Wood when freshly cut can contain as much as 50% mois-
ture, depending on the type. Air dried wood, when under
ideal conditions, will still contain approximately 20%
moisture. The moisture, along with flue gas products, are
vented outside by way of the flue pipe and chimney. Flue
gas products, when chilled, condense into liquid creosote
which may become a crystal (solid form) as temperatures
increase with heat requirements.
The heat control method on furnaces when burning wood,
is the size of the fuel charge along with the control of
combustion air, to increase or decrease the rate of burning
which governs the heat output.
To help prevent creosote in both grate and base burners,
burn dry seasoned wood, hard wood is more desirable
than soft wood. Govern your wood load with the heat
output required. Spring and fall require frequent small
charges. A small intense fire produces less creosote.
Short flue pipe runs help to keep the gases above the dew
point.
The interior chimney holds and retains heat longer result-
ing in less condensation than the exterior chimney.
A good draft produces a hotter fire and exhausts the flue
gases outside more rapidly at higher temperatures pre-
venting condensation of flue products.
A solid fuel furnace in need of cleaning, will have poor
draft creating a lazy fire and eventually, if ignored, may
smoke around the doors.
(Poor draft in a clean system can also produce smok-
ing around the door). This choked condition with soot
and creosote can only be relieved by cleaning the entire
system as frequent as necessary, if neglected it will cause
a chimney fire, which could result in property loss and
danger to lives of occupants.
Wood burning equipment must be vented into a factory
built OR masonary chimney. Chimneys must be built to
Building and Energy Board standards. Do not neglect
cleaning, or deliberately set your chimney on fire to burn
out the soot and creosote. If no damage is done to the
house, there will be damage to the chimney caused by
extreme heat. Not even the best chimneys are designed for
withstand repeated chimney fires.
