CATALYTIC COMBUSTOR, CLEANING
Under certain conditions, ash particles may become attached to the face of the combustor. Th
ese may be seen
while the combustor is in the glowing stage, or when the fi re is out. Any deposit on the visible face of the
combustor should be removed. Wait until the fi re is out and the stove is cold. (Hot ash in a vacuum cleaner bag
will burn.) Brushing the combustor with a soft bristle paint brush will remove some deposits. Passing a plastic
vacuum cleaner wand or brush near the face of the combustor will remove most deposits. Never scrape the
combustor with any hard tool or brush. Some stove owners have run pipe cleaner through every individual cell
of the combustor. Th
is is not needed, and may actually do more harm than good. Limit cleaning to the face of
the combustor.
NOTE:
Never remove a combustor without approved combustor gasket in hand as original gasket will fall apart
when removed from stove. Remember to re-install the Flame Shield (the perforated plate) in same position it
was found.
TIP:
A nice hot fi re will usually prove to be the best method of cleaning the combustor of deposits.
CATALYTIC COMBUSTOR, REPLACEMENT
Th
e catalytic thermometer on top of the stove should read in the active zone aft er the stove has been in operation
for several hours. If the thermometer’s indicator needle does not stay above the 1/3 mark in the active zone, even
with a hot fi re, over a 7-10 day period of regular use, the combustor may need replacement. If the combustor
needs replacing then discontinue use of the appliance until the combustor is replaced. If the combustor must be
examined or replaced contact your Blaze King dealer.
CATALYTIC COMBUSTOR, TESTING
(Conduct test with fans off ) Test the combustor in your Blaze King as follows:
Build a fi re using the same technique (paper, kindling, logs) you have used in the past. Leave the thermostat
knob on a
MED
setting. When the fi re is well established (within one to three hours) turn the thermostat knob
between
LOW
and
MED
. A properly operating combustor will remain active, and the combustor thermometer
will remain in the “active” zone until the wood load is mostly consumed. A “tired” or “dead” combustor will,
with the thermostat on
MED
or lower, go out completely, and the thermometer needle will fall into the “inactive”
zone. Repeat this procedure several times over several days. (Remember that the combustor thermometer
has a built-in lag of 4-8 minutes.) If, aft er several test burns, the thermometer will not indicate an “active”
combustor, it may require cleaning or replacement. Contact Blaze King for a replacement combustor, read
“
REPLACEMENT PARTS”.
It is also possible that the thermometer, itself, may not be reading accurately.
Before condemning the combustor, read
“THERMOMETER”.
