CLEANFIRE OUTDOOR FURNACE • OWNER'S MANUAL
Adding Heat Load
NOTE: During initial start-up, a considerable amount of moisture from condensation
will collect inside the firebox and heat exchanger and may drip out of the Reaction
Chamber door. This is normal and the moisture will evaporate after the first couple
of fuel loads.
1. With no heat load draw in the system, monitor the operation of
the outdoor furnace until the water temperature reaches the water
temperature setpoint.
2. Turn on the pump(s); then start a heat load draw in the system by
turning up the thermostat in the house. Monitor the outdoor furnace for
one hour or until another cycle occurs (i.e., outdoor furnace goes from
combustion to idle mode). If the water temperature drops and does not
recover to the water temperature setpoint within one hour of starting
the heat load draw, the heat load draw should be shut off, allowing the
furnace to cycle to the idle mode again.
NOTE: The outdoor furnace will not operate satisfactorily if the heat load is higher
than the output capacity of the outdoor furnace.
3. At this point, there should be glowing coals established in the bottom
of the firebox. The firebox can be filled with dry, seasoned split wood.
Ash Removal Frequency
During the first week of operation, check the level of ash in the Reaction
Chamber every two days. Ash needs to be removed from the Reaction
Chamber before it obstructs the combustion air flow for efficient
operation. Clean the Reaction Chamber before it becomes 1/2 full of ash
(approximately 5" or 13 cm deep in any area of the Reaction Chamber).
Adding Wood
1. CleanFire 700/500 only - Slowly lift and push the bypass door handle
toward the back of the outdoor furnace to open the bypass door; then
wait for 15 seconds.
NOTE: The alarm is a reminder that the bypass door is open. During a cold start, it will
continue to sound.
Keep your face away and stay as far away as possible from the firebox door area
when opening the door.
