APPENDIX D: CROSSFIRE THEORY OF OPERATION
BURN PHASE
Multiple heat lights indicate the control panel burn phase. There are five lights (4 yellow and one red) used to
indicate the relationship to the system’s heat settings. Pushing the control panel’s HEAT LEVEL switch will
cause a heat light to cycle one level up from Heat 1 through Heat 5. Once the Heat 5 setting has been reached,
if the HEAT LEVEL button is pushed again, the heat setting will cycle over again starting at Heat 1. The
operator controls the heat output of the stove by utilizing Heat 1 through Heat 5 settings. Heat 1 setting
provides the lowest heat output from the system and the longest time between refills of the fuel hopper. Heat 5
provides the maximum heat output from the system and the shortest time between refills of the fuel hopper.
Changing any heat setting up or down by one increment will cause a delayed (it takes time for both the fuel
and air adjustments to impact the burn chamber) increase or decrease in the heat output of the system.
Changing any heat setting up or down by two or more increments will require an increased amount of time
before the burn rate of the stove stabilizes.
The control system automatically adjusts to the requested heat settings without further intervention of the
operator. NOTE: The control panel display immediately reflects the final heat setting requested by the
operator regardless of how many incremental changes occur but the operator should remember that it takes
“time” for the stove to stabilize to the new heat setting.
COOL DOWN PHASE
Any time the system is switched off by holding the on/off switch for more than 3 seconds during normal stove
operation, the control system will revert to the cool down phase. During the cool down phase the room,
exhaust, and stir pot motors will be operated at high speed. The auger motor will cease to operate thereby
ensuring minimal time for the burn phase to be extinguished. During the cool down phase the heat indicator
lights will step down from red (5
th light being on) to the first yellow light being on. This process will be
repeated until such time as the control system senses that the stove has been properly cooled down. The auger
and igniter lights are both off during the cool down phase.
