Combustor – Use and Cleaning
This heater uses a combustor to improve efficiency and reduce emissions. To work at its
optimum, the combustor must be kept free of excessive ash. If the heater becomes sluggish
when the bypass is closed, flyash may be building up on the combustor. See the directions
below to inspect and clean the combustor with the included brush.
Inspecting & Cleaning the Combustor
The combustor becomes very hot during operation. Let the heater cool before cleaning the combustor.
The combustor is located directly above
the firebox opening. Make sure the
square openings are open for air to pass
through. If ash is accumulating, use the
brush to clear off visible flyash.
NOTE: To thoroughly clean the
combustor, use an ash vacuum to pull
flyash from the combustor (see page 34).
Testing your Combustor
A combustor that is not functioning may still show active temperatures during the medium and high burn rates with
the primary fire providing enough heat to hold output temperatures above 500°f. To check the combustor function
burn your fireplace for at least 2-3 hours on the medium to high setting ensuring a full coal bed covers the firebox
floor and the unit is at operating temperature. Set your burn rate to medium low and monitor the combustor output
temperature. The combustor should maintain a temperature above 500°f. If your combustor temp falls below 500°f
perform this test two or three times to ensure the results. If your results are the same your combustor may need
cleaning or replacement. Note: If you reload your fireplace before starting your burn test burn the new fuel load on
high for at least 20 min before setting your burn rate to medium low. If the combustor is determined to be inactive,
discontinue use of the appliance until the combustor is replaced.
