SMOKES OUT FUEL DOOR WHEN OPEN (SEE ✸ ✸ ✸ ✸)
1. The primary air control is closed.
2. The chimney is too cool. Set the primary air control on
"HIGH" for a few minutes before opening the fuel door.
3. Excess creosote will not only restrict your draft but it will
create a risk of a creosote fire. Strictly adhere to mainte-
nance requirements as outlined in this manual. If excess
creosote has built up on the inside of the firebox sides
and door, burn a small hot fire at intervals that are more
frequent with air control on HIGH for a few minutes.
4. Deposits may have built up in the chimney and are re-
stricting the draft, or the spark arrester on top of the
chimney may be plugged.
5. Chimney diameter too large or too small to provide ade-
quate draft.
6. The house is too airtight (usually takes 20 to 30 minutes
for problem to appear as stove lowers air pressure in
house). Crack a window open or provide an outside
source of air near stove.
7. Insufficient vertical height to chimney to achieve adequate
draft.
DOES NOT PRODUCE ENOUGH HEAT (✸ ✸ ✸ ✸)
1. Using green or insufficiently cured wood.
2. Excessive draft.
3. High ceilings (heat rises quickly, but can be recirculated
by a well-placed ceiling fan with a winter/summer switch).
4. The area to heat is too large (square foot heating esti-
mates are based on "average" climates and home de-
sign).
5. There is an obstruction in the chimney.
6. The chimney or chimney cap is restricted by creosote
preventing enough draw to sustain a "high" heat output
rate.
DOES NOT MAINTAIN A FIRE (✸ ✸ ✸ ✸)
1. Soft wood does not burn as long or as well as seasoned
hardwood resulting in a short burn time.
2. Wood size too small. Burns at too rapid a rate.
3. The gasket seal on the fuel door, or glass is leaking air.
Repair or replace it if necessary.
4. Excessive Draft.
5. There may be an obstruction in the chimney.
BACKPUFFING (✸
✸ ✸ ✸)
1. Downdraft in the chimney (a special wind cap may be
needed).
2. The house is too air tight (ventilation is needed).
1. Insufficient vertical height to chimney to achieve adequate
draft.
ODORS
1. Creosote accumulation in firebox (brush out on next
cleaning).
2. Chimney downdraft when stove is not operating (close
the primary air control).
2. Paint curing on first several burns.
DIRTY GLASS (✸
✸ ✸ ✸)
1. Poor draft conditions.
2. Long burn periods at low draft settings.
3. Burning wet, pitchy or spongy wood.
4. Poorly arranged logs (too close to glass).
✸ ✸ ✸ ✸ Draft problems; if installing into a larger flue, it may
be necessary to use a full length liner to achieve ade-
quate draft for the appliance. A draft gauge should read
a minimum of .05" w.c. (inches water column) not to
exceed .07" w.c. for optimum performance (See Draft
Requirements, page 8).
OVERFIRING DAMAGE
If the heater or chimney connector glows, you are overfiring.
Other symptoms may include: Cracking, warping or burning
out of components, stove glass may develop a haze, which
will not come off with cleaning.
Overfiring of a stove is a condition where excessive tem-
peratures are reached, beyond the design capabilities of the
appliance. The damage that occurs from overfiring is not
covered under the manufacturers limited warranty.
The following are a few conditions that should be evalu-
ated and (corrected if necessary) if an overfiring condition
is suspected:
Overfiring Caused From Improper Installation - Ensure
that all installation requirements have been met as outlined
in the installation manual. The chimney should be clean and
in good repair. A draft test should be performed to determine
if the draft requirements of the appliance are being met. A
draft gauge should read between .05 and .07 inches water
column (" W.C.). Excessive draft (above .07 " W.C.) will al-
low too much combustion air to be pulled in which results in
hotter burns. Too little draft (below .05 " W.C.) will not allow
enough combustion air delivery to maintain a fire (this may
result in improper operation of appliance, i.e. wont maintain
fire unless fuel door is left open. See below, Overfiring
Caused From Improper Operation).
Overfiring Caused From Improper Operation - Operate
this appliance only as outlined in this manual. Never burn the
appliance with the fuel door open or ajar. Do not operate this
stove with the Air Control in the "open" position (pulled out)
for extended periods. This wastes fuel and can cause dan-
gerous overfiring conditions. NEVER leave the stove unat-
tended on high settings.
Overfiring Caused From Improper Maintenance - Strictly
adhere to all maintenance requirements at frequent intervals
as prescribed in this manual including cleaning of flue and
stove. Should the fuel door or glass gaskets become worn or
damaged, they should be replaced.
Overfiring Caused From Improper Fuel - This appliance is
approved for use with natural dry well seasoned wood only
(ask your authorized dealer what are approved fuels for your
area). Do not burn garbage, particleboard scraps, or pressed
logs using bonding agents because they can produce condi-
tions that will deteriorate metal. Do not overload or use kin-
dling wood or mill ends as primary fuel as this may cause
overfiring.
