CATALYST MONITORING
CATALYTIC COMBUSTOR, REPLACEMENT
BLAZE KING RECOMMENDS YOUR DEALER PERFORM THIS TASK
The catalytic thermometer on top of the stove should read in the active zone after 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 fire, over a 7-10 day period of regular use, the combustor may need replacement or cleaning, see
“CATALYST MONITORING”. 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.
The removal of a Blaze King Catalytic combustor requires
a small flat blade screwdriver or pocket knife. The stove fire
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 after the fire is out. After waiting 12 hours,
first remove the flame shield by simply lifting the shield off the two
tabs at either side. Pay particular attention to orientation as there
is a top and bottom edge to the flame shield.
2.
Once you remove the flame shield, you’ll find the combustor.
The honeycomb combustor can be made of different materials
such as cordierite, mulite or even stainless steel. They 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”.
3.
The combustor has a metal tab across the bottom and on each
side of the combustor. Using a flat blade screwdriver or pocket
knife blade, slide the blade behind the metal tab and the heavy
steel dome of the stove. The 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.
