TROUBLE SHOOTING AND PROBLEM SOLVING
1. Problem:
Smoke puffs from furnace
Solution:
A. Check chimney draft. Check for blocked chimney
or flue pipe. Use mirror to check chimney clearance.
B. Check ash pit — if it is too full, empty.
C. Make sure furnace room is not too airtight.
D. Make sure all of chimney mortar connections are
airtight.
E. Check ash drawer. Make sure it’s airtight.
F. Check chimney for possible down-draft caused
by taller surrounding trees or objects. Correct with
proper chimney vent cap.
G. Check the possibility of a cold chimney forcing cool
gases backward. Remedied by properly insulating
chimney with non-combustible liner — non-combus-
tible insulation.
H. Fuel may be too green.
I. Make sure no other fuel burning devices are con-
nected to the chimney impairing the draft.
J. Check chimney draft, it should be .06 inches of
water column. This service is provided by a certified
chimney sweep.
2. Problem:

Solution:
A. Check home insulation — is it adequate?
B. Check hook-up to furnace — is it installed correctly?
C. Cool air inlet may be inadequate or furnace room
too airtight.
D. Your wood fuel may be too low grade. Hardwoods
are recommended.
E. Make sure your hot air duct (and other duct work)
is airtight.
F. If furnace room is warm but your home isn’t, check
back draft dampers.
G. Is air to the blower available?
3. Problem:
Excess smoke or flames coming out door when refueling

refuel.
B. Check length of flue pipe to chimney. Your unit
should be within six (6) feet of your chimney.
