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.

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 on page 10).
OVERFIRING DAMAGE
If the heater or chimney connector glows, you are overfir-
ing. Other symptoms may include: Cracking, warping or
burning out of components, gold doors may turn color, 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 manufacturer’s limited warranty.
The following are a few conditions that should be evalu-
ated and (corrected if necessary) if an overfiring condi-
tion 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 de-
termine 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 allow 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 or ash drawer 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 or ash drawer 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 dangerous overfiring conditions. NEVER
leave the stove unattended on high settings.
Overfiring Caused From Improper Maintenance - Strictly
adhere to all maintenance requirements at frequent inter-
vals as prescribed in this manual including cleaning of flue
and stove. Should the fuel door, ash drawer or glass gas-
kets 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 conditions that will deteriorate metal. Do not over-
load or use kindling wood or mill ends as primary fuel as
this may cause overfiring.
