TROUBLESHOOTING
PROBLEM
CAUSE
REMEDY
Smoke puff back when loading,
poor burning, insufficient heat
1. Insufficient draft.
2. Insufficient make-up.
1. Debris or creosote could be blocking flue.
Inadequate chimney height or design could be
causing downdrafts. Check chimney connector for
air leaks and seal with furnace cement. Adjust
barometric regulator to higher setting.
2. The house could be so well insulated that
infiltration air is not getting in to replace air used in
combustion. Open a window slightly in furnace
room or install a vent to the outside in furnace area.
Poor heat throughout house
while burning wood
1. Poor quality wood.
2. Cold air return closed or
blocked.
3. Duct joints leaking air.
4. Check flue gas temperature.
5. Fan control not adjusted
properly.
1. Burn only wood which has been air-dried for at
least six months, preferably a year or more. Use
hardwoods such as hickory, oak, maple, etc. for
highest heat value per load.
2. Check to insure that all cold air return vents are
open and not blocked with furniture, etc.
3. Make sure that all duct joints are airtight. Apply
duct tape to seal.
4. Normal operating range is 300-600
F. Lower
temperature would indicate insufficient draft or
inadequate combustion air. To check flue gas
temperature, we recommend that a smoke pipe
surface thermometer or probe-type thermometer be
used.
5. Insure that primary furnace blower is turning on
to distribute heat effectively. Lower “FAN ON”
settings on primary furnace fan control to start
circulation earlier.
Auto Damper Control won’t hold
setting
1. Auto damper control not in
adjustment.
1. Adjust tension on shaft by tightening only the
shaft nut closest to the coil spring. Using a 7/16”
open end or adjustable wrench, turn tension nut
counter-clockwise moving it only a quarter of a turn
at a time. Check tension on knob. Do not over
tighten.
Loose Knob on Auto Damper
Control
1. Loosened through usage.
1. With furnace in cool mode, turn shaft so that
a
rm of coil spring is in 10 o’clock position. Turn
loose knob to 12 noon position. Tighten set screw
with 5/64” Allen wrench.
Paint discoloration
(whitish appearance)
1. Overheating.
1. Paint is rated for 900
F surfaces. Overheating
of furnace will cause a whitish appearance on
outside of combustion chamber surfaces (it is
normal around back & door). Reduce chimney
draft to control overheating. Pink or white
discoloration on chimney also is normal.
NOTE:
To cover discoloration, obtain a high-combustion
flat black spray paint from hardware store or
fireplace shop.
Creosote Formation
1. Burning too cool of a fire.
2. Auto Damper setting too low.
