WARNING: THIS WOOD HEATER CONTAINS A
CATALYTIC COMBUSTOR, WHICH NEEDS
PERIODIC INSPECTION AND REPLACEMENT FOR
PROPER OPERATION. IT IS AGAINST FEDERAL
REGULATIONS TO OPERATE THIS WOOD HEATER
IN A MANNER INCONSISTENT WITH OPERATING
INSTRUCTIONS IN THIS MANUAL, OR IF THE
CATALYTIC ELEMENT IS DEACTIVATED OR
REMOVED
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. Following is a list of items that should
be checked on a periodic basis
-Combustors should be visually inspected at least
three times during the heating season to determine if
physical degradation has occurred. Actual removal of
the combustor is not recommended unless more
detailed inspection is warranted because of decreased
performance. If any of these conditions exists, refer to
Catalyst Troubleshooting section of this owner's
manual.
-This catalytic (or hybrid) heater is equipped with a
thermometer to monitor catalyst operation. Properly
functioning combustors
temperatures in excess of 500 °F, and often reach
temperatures in excess of 1,000 °F. If catalyst
temperatures are not in excess of 500 °F, refer to the
Catalyst Troubleshooting section of this owner's
manual.
-You can get an indication of whether the catalysts are
working by comparing the amount of smoke leaving
the chimney when the smoke is going through the
combustor and catalysts light-off has been achieved,
to the amount of smoke leaving the chimney when the
smoke is not routed through the combustor (bypass
mode).
1. Light stove in accordance with operator's
instructions
2. With smoke routed through the catalysts, go
outside and observe the emissions leaving the
chimney.

3. Engage the bypass mechanism and again
observe the emissions leaving the chimney.
Significantly more smoke will be seen when the
exhaust is not routed through the combustor

REMOVING REPLACING THE BAFFLE
1. Allow the stove and ashes to fully cool.
2. Remove the top baffle by gently lifting the baffle
and pushing the retainer clip up and away from
the baffle. Remove the baffle from the stove.

4. Use a small vacuum nozzle or soft bristled
brush to remove any accumulated ash or
soot on the face of the catalyst. Inspect the
catalysts for any unusual warping, corrosion,
or plugged openings.
6. If any unusual conditions are found, remove
the catalyst blocks – See replacing the
catalysts.
7. Replace the baffle.
