TROUBLESHOOTING
PAGE 21
CATALYST SUBSTRATE CRACKING
1. Normal operation, as long as combustor re-
mains intact. If cracking causes large pieces to
fall out, replace combustor.
2. Mishandling or abuse. Handle with care.
3. Warped housing (see Overfiring Damage on this
page).
CATALYST SUBSTRATE
1. Extreme thermal shock. Combustor is being
worked too hard.
2. Excessive draft. Correct installation (see Draft
Requirements, page 9).
CATALYST PEELING
Extreme Temperatures (over-firing) at combustor sur-
face can cause the catalyst to peel. Some minor peeling
does not affect function. Severe peeling would close cell
openings and cause a plugging problem. If peeling is
severe, replace combustor. Do not overfire appliance.
See Overfiring Damage on this page.
TAR AND LIQUID CREOSOTE LEAKING FROM
METAL FLUE JOINTS
1. No chimney cap on chimney. Install cap.
2. Metal flue assembled improperly. Top flue sec-
tions should be inserted into lower flue sec-
tions.
DENCE SMOKE LEAVING CHIMNEY
1. Water vapor (on cold still days water vapor may be
mistaken for smoke). Water vapor is normal and
should be of little concern.
2. Wet, pitchy woods being burned. Burn dry seasoned
wood only.
3. Bypass in open position. Close bypass.
4. Combustor not functioning. See Catalyst Replace-
ment, page 18.
OVERFIRING DAMAGE
If the heater or chimney connector glows, the appliance is
overfiring. Other symptoms may include: Cracking, warping
or burning out of components, catalytic combustor may dete-
riorate, stove glass may develop a haze which will not come
off with cleaning, catalytic combustor housing grate may
crumble, etc. Overfiring of a stove is a condition where ex-
cessive temperatures are reached, beyond the design capa-
bilities of the appliance. The damage that occurs from over-
firing is not covered under the manufacturers limited war-
ranty. The following are a few conditions that should be
evaluated and (corrected if necessary) if an overfiring condi-
tion is suspected:
Overfiring Caused From Improper Installation
The venting system must satisfy the draft Requirements of
the appliance. The appliance is merely one component of a
larger system. The other equally important component is the
venting system, which is necessary for achieving the required
flow of combustion air to the fire chamber and for safely re-
moving unwanted combustion byproducts from the appli-
ance. If the venting system’s design does not promote these
ends, the system may not function properly, which may cre-
ate performance problems as well as may be a safety haz-
ard. To 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 appli-
ance are being met. A draft gauge should read between .05
and .07 inches water column (W.C.I.). Excessive draft
(above .07 W.C.I.) will allow too much combustion air to be
pulled into the firebox, which results in hotter burns. Too little
draft (below .05 W.C.I.) will not allow enough combustion air
delivery to maintain a fire well or cause performance prob-
lems such as smoking (this may result in improper operation
of appliance, i.e. will not maintain fire well unless catalytic
bypass is left open, or with fuel door left open (see following -
Overfiring Caused From Improper Operation).
Overfiring Caused From Improper Operation
Operate this stove only as outlined in this manual. Never burn
the stove with the fuel door open or ajar. Do not operate this
stove with the air intake control in the "open" position for ex-
tended 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 fre-
quent intervals as prescribed in this manual including
cleaning of flue and stove. Should the fuel door or glass
gaskets become frayed, worn or damaged, they should
be replaced with same size and type as original.
Overfiring Caused From Improper Fuel
This appliance is approved for use with natural dry well sea-
soned wood only (consult your dealer for approved fuels in
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
overload or use kindling wood or mill ends as primary
fuel as this may cause overfiring. If any of the stove
body seams are found loose or damaged, the seams
should be cleaned with a wire brush then resealed with
furnace cement (this needs to be done annually, see
Stove Seams, page 18).
