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. See Troubleshooting section for detailed
instructions BEFORE attempting to remove catalyst.
This catalytic heater is equipped with the means to monitor catalyst operation. Properly functioning combustors
typically maintain temperatures in excess of 1000
o F. If catalyst temperatures are not in excess of 500 o refer to
Catalyst Troubleshooting section of this owner’s manual.
CAUTION AGAINST OVER-FIRING
Do Not Over-fire This Heater.
Attempts to achieve heat output rates that exceed heater design specifications can result in permanent damage to
the heater and to the catalytic combustor.
ASH REMOVAL
Whenever ashes build up in the firebox and when the fire has burned down and cooled, remove excess ashes.
Leave an ash bed approximately 1 inch deep on the firebox bottom to help maintain a hot charcoal bed. To
remove ashes the dump is located at the left inner bottom. By lifting the dump door, place the ashes through the
dump opening. The ashes fall directly into the ash pan. The ash pan is located at the left side under the hearth
behind the cover door.
NOTE: Be sure to turn the room air blower off before removing ashes. Open cover door and slide ash pan out.
NOTE: Fueling and ash removal door (s) must remain closed when in operation.
Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be
placed on a non-combustible floor or on the ground, away from all combustible materials, pending final disposal.
The ashes should be retained in the closed container until all cinders have thoroughly cooled.
NOTE: Be sure to turn room air blower back on when job is completed.
NOTE: The room heater is not to be connected to any air distribution duct.
CREOSOTE - FORMATION AND NEED FOR REMOVAL
When wood is burned slowly, it produces tar and other organic vapor, which combined with expelled moisture
forms creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a
result, creosote residue accumulates on the flue lining. When ignited this creosote makes an extremely hot fire.
NOTE: SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE.
