VII. CATALYTIC COMBUSTORS
1. GENERAL INFORMATION
(A) TAMPER WARNING
This wood heater contains a catalytic combustor, which
needs periodic inspection and replacement for proper
operation. It is against the law to operate this wood
heater in a manner inconsistent with the operating
instructions in this manual, or if the catalytic element is
deactivated or removed.
(B) MANUFACTURER AND WARRANTY INFO
The combustors supplied with this heater are Applied
Ceramics Versagrid Catalytic Converter. Consult the
catalytic combustor warranty also supplied with this
heater.
Warranty claims should be addressed to:
Applied Ceramics - Warranty Department
P .O. Box 29664
Atlanta, GA 30359
(404) 448-6888
Warranty Claims MUST have the following items:
1. Warranty Claim Form
2. Dated Proof of Purchase
3. Check for proper amount (including postage and
handling)
4. APPLIED CERAMICS Catalytic Combustor
2. CATALYST MONITORING
It is important to periodically monitor the operation of
the catalytic combustor to ensure that it is functioning
properly and to determine when it needs to be replaced.
A non-functioning combustor will result in a loss of
heating efficiency and an increase in creosote and
emissions.
Check these items periodically:
* Visually inspected combustors at least three times
during the heating season to determine if physical
degradation has occurred. Actual removal of the
combustor is not recommended unless a more detailed
inspection is warranted because of a decrease in
performance. If any of these conditions exist, refer to
the Catalyst Troubleshooting Guide.
* This catalystic heater may be equipped with a
temperature probe to monitor catalyst operation.
Proper functioning combustors typically maintain
temperatures in excess of 500 degrees Fahrenheit and
often reach temperatures in excess of 1000 degrees
Fahrenheit. If catalytic temperatures are not in excess
of 500 degrees, refer to the Catalyst Troubleshooting
Guide or further information located in this manual.
* To determine if the catalyst is working, compare the
amount of smoke leaving the chimney when the smoke
is going through the combustor and catalyst light-off
has been achieved to the amount of smoke leaving the
chimney when the smoke is not routed through the
combustor (bypass mode - damper open).
1. Light the stove in accordance with instructions given
on how to achieve catalyst light off.
2. With smoke routed through the catalyst, go outside
and observe the emissions from the chimney.
3. Engage the bypass mechanism (open the damper)
and again observe the emissions leaving the chimney.
Significantly more smoke should be seen when the
exhaust is not routed through the combustor (bypass
mode - damper open). Be careful not to confuse smoke
with steam from wet wood.
The 52 Bay was designed to allow the owner to
monitor the catalyst temperatures. A small port is
located on the top of the stove, inside the unit. From
that port, wires may be led out of the unit to a
temperature monitoring device. Some Gemini models
have this wiring already done. The port is positioned
to allow for temperatures to be taken approximately 1"
behind the right catalyst. The thermocouple and
monitor should be compatible and should read
temperatures to approximately 1800 degrees F.
Front Mounted Catalytic Probe
Locate screw above the door and to the left of the
damper. Remove the screw and insert catalytic probe.
