TROUBLE SHOOTING
Problem:
Solution
Smoke puffs from
furnace
Check chimney draft. Check for blocked chimney or flue pipe. Use mirror to check chimney
clearance.
Check ash pit — if it is too full, empty.
Make sure furnace room is not too airtight.
Make sure all of chimney mortar connections are airtight.
Check ash drawer. Make sure it’s airtight.
Check chimney for possible down-draft caused by taller surrounding trees or objects. Correct
with proper chimney vent cap.
Check the possibility of a cold chimney forcing cool gases backward. Remedied by properly
insulating chimney with non-combustible liner — non-combustible insulation.
Fuel may be too green.
Make sure no other fuel burning devices are connected to the chimney impairing the draft.
Check chimney draft, it should be .06 inches of water column. This service is provided by a
certified chimney sweep.
Inadequate heat
being delivered to
your home
Check home insulation — is it adequate?
Check hook-up to furnace — is it installed correctly?
Cool air inlet may be inadequate or furnace room too airtight.
Make sure your hot air duct (and other duct work) is airtight.
If furnace room is warm but your home isn’t, check back draft dampers.
Is air to the blower available?
Excess smoke or
flames coming out
door when refueling
Wait 15 seconds and open door SLOWLY — then refuel.
Check length of flue pipe to chimney. Your unit should be within six (6) feet of your chimney.
Make sure chimney cap is not too close to the top of the chimney.
Check chimney draft — make sure chimney flue pipe is clean and chimney is of adequate height.
Slide baffle should be pulled out prior to load door opening.
Distribution blower
vibrating
Tighten blower wheel to motor shaft.
Check for bad fan bearings.
Distribution blower
continues to run or
will not run
Check fan limit or heat sensor and cable.
Check to see that blower is properly wired. (See Wiring and Assembly Instructions).
Check fuse box or power source.
Check power supply.
Odor from first fire The odor from new steel should disappear in a few hours.
If the odor remains, call you dealer immediately. A bad weld can cause a fume leak.
Excessive Creosote
Make sure your unit is serviced by its own proper chimney.
Check length of flue pipe and its connections.
Make sure you are burning the smallest, hottest fire to adequately heat your home.

If the fire goes out
or does not hold
over night
Poor Draft.
Incorrect damper settings.
Improper firing methods if burning coal.
More combustion air needed.
Coal not sized to the furnace. We recommend 1” to 3” diameter pieces of coal.
Ashes, if allowed to accumulate in the ash pit, will not allow passage of the required air for
combustion. Keep ash pit clean.
This furnace is not to be used with an automatic stoker unless so certified.
