1. Door seal faulty or door frame obstructed - If there is smoke coming from
between the firebox door and the front of the door frame for more than a short
time after reloading, scrape the face and surface area of the door frame to remove
any deposits. Check the condition of the firebox door seal and replace if necessary.
2. Door hinges and/or latch need adjusting - Adjust the hinges and/or latch

E. OUTDOOR FURNACE IS OVERHEATING
1. Air entering through the firebox door or smoke coming out of the firebox
door when the door is closed
- Make sure the firebox door is properly latched
and check the condition of the firebox door seal. If it is not sealing properly

close tightly, adjust using the appropriate procedure (see Owner Serviceable
Items).

NOTE: If the outdoor furnace is operated with the door open, the firebox door seal may be damaged.
2. Solenoid and/or air regulating disc stuck open or obstructed - Remove any
obstructions. Lubricate with WD-40 or similar type of lubricant. If replacement
is necessary, refer to Fig. 71 for the factory settings for the air regulating discs.
NOTE: If the outdoor furnace loses water from boiling, the problem should be identified and
repaired immediately. Under normal operation, little or no water needs to be added. Adding water
to the furnace may cause corrosion if not immediately treated with Corrosion Inhibitor Plus™ to
the proper pH and nitrite levels. In addition, the amount of dissolved solids in the system (due to
adding additional water) can cause problems.
3. Water is not circulating - Check to make sure the pump is operating and water
is circulating continuously through the supply and return lines to keep water
temperature uniform in the outdoor furnace.
4. Circulation valve(s) closed - Be sure the proper valves in the system are open to
allow circulation.
