CATALYST MONITORING cont.
CATALYTIC COMBUSTOR, REPLACEMENT
BLAZE KING RECOMMENDS YOUR DEALER PERFORM THIS TASK
Th
e catalytic thermometer on lower left -hand side of the appliance should read in the active zone aft er the appliance
has been in operation for several hours. If the thermometer’s indicator needle does not stay in the active zone, even
with a hot fi re, over a 7-10 day period of regular use, the combustor may need replacement or cleaning, see “CATALYST
MONITORING” on page 28. 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.
1.
Th
e removal of a Blaze King Catalytic combustor requires a small fl at
blade screwdriver or pocket knife. Th
e appliance fi re must be out for
at least 12 hours prior to the removal process. A combustor can reach
1400°F and hold high temperatures for several hours even aft er the fi re
is out. Aft er waiting 12 hours, fi rst remove the fl ame shield by simply
lift ing the shield off the two tabs at either side.
2.
Once you remove the fl ame shield, you’ll fi nd the combustor. Th
e
honeycomb combustor can be made of diff erent materials such as
cordierite, mulite or even stainless steel. Th
ey are all the same with
regard to removal and caution should be taken so as to not drop or
damage the combustor. If your combustor has never been cleaned
according the manufacturers directions, you may wish to clean the
combustor before replacing it with a new combustor, see “CATALYTIC
COMBUSTOR CLEANING” on page 28.
3.
Th
e combustor has a metal tab across the bottom and on each
side of the combustor. Using a fl at blade screwdriver or pocket knife
blade, slide the blade behind the metal tab and the heavy steel dome of
the appliance. Th
e dome is the housing that surrounds the combustor.
Apply slight pressure until the combustor begins to move forward, about
1/4”. Repeat the process on the opposite end tab. By working back and
forth the combustor will work free of the dome housing. It is normal for
the gasket surrounding the metal band to fall apart during this process.
New combustors are shipped with a new gasket.
