FORGE OUTDOOR COAL FURNACE • OWNER'S MANUAL
• Reduce RESET CYCLE UNDER AIR DURATION (Menu #11). is will
shorten the time it takes the under air actuator to reach its maximum opening
position.
• Reduce RESET CYCLE OVER AIR DURATION (Menu #15) or RESET
CYCLE OVER AIR START SETTING (Menu #13). is may result in
slightly more smoke, but will force more air through the coal bed.
• Reduce PULSE CYCLE DELAY SETTING (Menu #19). is will reduce
the amount of time between pulses. Especially helpful if there will be longer
periods of down time, but may also result in a high temperature alarm.
• Increase PULSE DURATION (Menu #20). Helps to maintain glowing coals,
especially during extended periods of down time, but may also result in a high
temperature alarm.
CONDITION: Outdoor furnace overheats and/or
repeated high temperature alarms.
RECOMMENDED ACTIONS:
• Make sure over and under air actuators are not stuck open.
• Make sure rebox and ash removal doors are closed and have a proper seal.
• Lower the water temperature setpoint.
• Increase PULSE CYCLE DELAY SETTING (Menu #19) and/or reduce the
PULSE DURATION (Menu #20).
• Reduce STANDARD RUN MODE UNDER AIR SETTING (Menu #10).
• Adjust the RESET CYCLE OVER AIR START SETTING (Menu #13)
and RESET CYCLE OVER AIR END SETTING (Menu #14). Setting the
RESET CYCLE OVER AIR END SETTING to zero will eliminate most
of the natural draft when the outdoor furnace is in Idle Mode and prevent a
constant climb in temperature. is is especially true when there isn’t a large
heat draw, such as during warmer months.
