APPENDIX D: THEORY OF OPERATION (cont’d)

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 (5th 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.

FAULT PHASE

The fault phase is indicated by all lights except the Country Flame logo light flashing on and off at a rapid pace. This event signifies that the control board has encountered an improperly operating system and requires intervention by either the operator or a properly trained service technician. In the event that the fault phase continues to flash lights, the operator should not try any repairs except those listed below without contacting their dealer or an authorized and properly trained service technician. Country Flame has made every effort to ensure the safety of the homeowner through proper use of this system. Any attempt to modify or circumvent the safety features of this product is prohibited by the manufacturer. In the event that the fault phase does not reset with the manufacturers recommended procedures, please contact your local authorized Country Flame service representative.

RESET CONDITION

Reset Condition #1 requires the system to properly proceed through cool down phase. By allowing cool down to occur the control panel will automatically shut off the system. In order for system shut off to occur all electronic controls must sense safe system temperatures. In the event “safe temperatures” are not sensed by the system, the control panel will continue to operate in the cool down phase until such time that safe temperatures are achieved or the operator intervenes. In order to perform a “hot restart” from the cool down phase, Reset Condition #2 must be followed.

Reset Condition #2 assumes the operator has shut down the system and has now decided that a restart of the system is required. In order to perform a restart the operator must press and hold the up heat (red) arrow for a minimum of 15 seconds. This will return the system to startup phase. Please refer to startup phase for specifics. All procedures in the startup phase should be followed in order to ensure burn phase is properly achieved from the hot restart phase. NOTE: A HOT RESTART CAN ONLY BE ACHIEVED FROM A COOL DOWN PHASE. In the event of a “fault phase” no hot restart can be initiated.

SYSTEM MAINTENANCE

There are two functions built into the control board that can be used to assist with maintenance or troubleshooting a system. These two control board functions are:

a)Prime State

b)Manual Control

The Prime State is utilized upon installing a new stove or after a fuel bin (hopper) has been depleted of fuel. The prime state can be entered by pressing and holding the on/off switch for a minimum of 15 seconds. By holding the on/off switch on for 15 seconds or more, the auger light (green) will be turned on and the heat lights will be sequenced from lowest to highest light being consecutively turned on to signify the auger being filled with fuel. This prime state will remain on for a maximum of 10 minutes or until the operator presses the
