TROUBLESHOOTING cont.
Combustor plugged or coated.
Clean combustor. See “CATALYTIC COMBUSTOR TESTING”
Combustor not functioning.
Check and test combustor. If needed replace combustor. See
“CATALYTIC COMBUSTOR, REPLACING”
Thermostat not operating properly.
Consult your blaze King Dealer.
By-pass door leaking or not closing completely.
Inspect and clean area around by-pass doors. Adjust or replace
gasket if necessary. Consult your Blaze King Dealer.
PROBLEM: Spots of creosote accumulation in chimney or chimney connector.
CAUSE
Air leaks in chimney or chimney connector.
SOLUTION
Inspect chimney and / or chimney connector. Repair or replace
as necessary. Check to be sure that the chimney connector is
installed correctly.
CAUTION: a leaking chimney connector is a fi re hazard and demands immediate attention.
Poor draft caused by an oversize fl ue, single wall
pipe, to many elbows, etc.
Measure draft with Manometer. See “DRAFTS”. Consult your
Blaze King dealer or a chimney sweep.
PROBLEM: Door glass quickly becomes coated with creosote.
CAUSE
Low thermostat setting or lowering the thermostat
setting too far, too quickly.
SOLUTION
Turn the thermostat to the warmest setting during the fi rst 20-30
minutes or until the fi re is well established after each reloading.
Poor draft caused by an oversize or short fl ue, etc.
Measure draft with Manometer. See “DRAFTS”. Consult your
Blaze King dealer or a chimney sweep.
Obstruction in chimney or cap screen.
Remove obstruction. Clean chimney and/or cap screen.
Strong, gusting winds causing downdraft in
chimney.
Install wind-resistant chimney cap.
Tightly sealed house, inadequate air supply.
Open a window, slightly, near the stove.
Burning poorly seasoned wet wood, or wood with
high pitch content.
Use seasoned wood with low pitch content, such as some types of
pine.
PROBLEM: The combustor temperature cannot be controlled. Turning the thermostat down often makes the
combustor temperature go up.
CAUSE
Turning the thermostat down, particularly in the fi rst half of the burn cycle, causes the fi re to emit more smoke, which is
fuel for the combustor. The combustor temperature therefore climbs for up to several hours. This is normal, and is of no
concern. As long as only the combustor temperature is elevated, there is nothing to worry about.
PROBLEM: Smoke spills from door opening when loading fuel
CAUSE
Spark arrestor screen on cap plugged.
SOLUTION
Clean spark arrestor screen to bare metal wire.
Chimney too cold.
Make certain double wall stove pipe is used in installation.
Not enough vertical rise.
Make certain a minimum vertical rise of 36” is observed prior to
elbows. Use two 45 elbows instead of 90 elbow.
Chimney not drafting.
Turn thermostat to highest setting, open bypass, leave loading
door closed and wait 5-10 minutes to increase chimney or fl ue
temperature.
