PROBLEM - CREOSOTE PLUGGING
Possible Cause:
Burning materials that produce a lot of char and
fl y-ash.
Solution:
Do not burn materials such as garbage, gift wrap, or
cardboard.
Possible Cause:
Burning wet, pitchy woods or burning large
loads of small diameter wood with the combustor in the operating
position without the thermostat needle in the active zone.
Solution:
Burn dry, seasoned wood, don’t engage the bypass
until the temperatures are high enough to initiate light-off
(indicated by the thermostat needle in the active zone).
Possible Cause:
Combustor not functioning. If proper burning
procedures have been followed to no avail, the combustor is not
functioning.
Solution:
Replace the combustor with a genuine Blaze King
combustor (failure to do so will void your warranty).
PROBLEM - CATALYST PEELING
Possible Cause:
Extreme temperatures (above 1800°F, or
1000°C.) at combustor surface can cause the catalysts to peel.
Over fi ring and fl ame impingement on the combustor are primary
causes. Minor peeling photo shows minor peeling that is normal
and does not aff ect function. Severe peeling photo shows that are
closed or plugged.
Solution:
Avoid extreme temperatures and fl ame impingement.
If peeling is severe, remove and replace combustor.
PROBLEM - CATALYST DEACTIVATION
Possible Cause:
Burning large quantities of trash, pressure-
treated lumber, or painted woods.
Solution:
Burn quality woods available in your area. If you
decide the catalyst has been deactivated, replace combustor with
a genuine Blaze King combustor (failure to do so will void your
warranty).
