CLEANFIRE OUTDOOR FURNACE • OWNER'S MANUAL
TROUBLESHOOTING OTHER SITUATIONS
A. OUTDOOR FURNACE IS NOT OPERATING CORRECTLY
Review the information in the Adding Wood section, starting at step 5.
1 . Out of wood - Add wood as necessary . Use correctly sized, seasoned wood .
2 . Area directly below the charge tube or Combustor obstructed - Inspect and
clean as required .
3 . Combustion air inlets obstructed - Clean as required to prevent the combustion
air inlets from being obstructed .
4 . Combustion air fan obstructed or not running - Check the screen over the fan
inlet and the inside of the fan for any obstructions .
5 . Airbox leaking - The airbox cover must be properly secured . Determine the
cause and correct .
6 . Primary air actuator motor closed - If the primary air actuator motor is not
operating properly, determine the cause and correct .
7 . Reaction Chamber, heat exchanger or the chimney plugged - If the Reaction
Chamber, heat exchanger or chimney are plugged, determine the cause and
correct .
8 . Door open - If the display on the controller indicates Door Open, close the
firebox door. Make sure the firebox door is properly latched and check the
condition of the firebox door seal. If it is not sealing properly (indicated by a
uniform indentation), replace the seal .
9 . Low water - If the display on the controller indicates Low Water, the system
senses a low water condition. Check the water level at the sight gauge and, if
necessary, add water according to the Water Quality and Maintenance section . If
adding water does not correct the problem, contact your WoodMaster dealer .
NOTE: If water needs to be added, it is very important to identify the cause of water
loss and correct immediately. A leaky system or overheating commonly leads to
dilution of the corrosion inhibitor and water jacket corrosion.
10 . Low water temperature for too long a period of time - The display on the
controller will indicate Fire Out and the controller will shut down the furnace if
the water temperature has been too low for too long . Determine the cause of the
water temperature being too low .
11 . Alarm condition - Refer to the FireStar Combustion Controller Operation
Manual .
12 . Chimney not drafting properly - Draft is the force which moves air from the
appliance up through the chimney . The amount of draft in your chimney depends
on the length of the chimney, local geography, nearby obstructions and other
factors . Draft occurs when the temperature in the chimney is high enough to
cause a negative pressure that "pulls" the exhaust up and out the chimney .
Proper draft is necessary for the CleanFire to operate optimally . Too much draft
may cause excessive temperatures in the appliance . Inadequate draft may
cause backpuffing and plugging of the chimney.
