CATALYST MONITORING cont.
CATALYTIC COMBUSTOR, REPLACEMENT
BLAZE KING RECOMMENDS YOUR DEALER PERFORM THIS TASK
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 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 27.
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 stove 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. Pay particular attention to
orientation as there is a top and bottom edge to the fl ame shield.
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 27.
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 stove. 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.
