UNDERSTANDING THE CONTROL BOARD

CONTROL PANEL

Turning the heater OFF/ON, as well as adjustments for the fuel feed rate and room fan speed are performed by pressing the appropriate button(s) on the control panel which is located on the lower left-hand side of your American Harvest heater. The insert model 6039I is located on the left facade.

This unit can be changed between an automatic operation or a manual operation. The controller comes default in the automatic mode.

Pressing the “ON” button on the control panel will begin the start- up sequence for the heater. Fuel will begin to feed through the auger feed system after 3 minutes. Pressing and holding the “ON” button will rotate the auger continuously until button is released, which feeds additional fuel.

Pressing the “OFF” button on the control panel will cause the heater to enter its shut-down sequence. The fuel feed system will stop pulling fuel from the hopper and, once the fire goes out and the heater cools down, the fans will stop running.

Pressing the “Heat Range” arrows, up or down, will adjust the amount of fuel being delivered to the burnpot.

The draft fan (exhaust) will come on as soon as the “ON” button is pressed. The fan will automatically adjust its speed in accordance to the heat range setting. However, this speed can be manually

operated by pressing the “Draft Fan” arrows up or down. “Draft Fan” when pressed, the display will show “Df-A”, which is automatic. Press the arrows again to adjust fan speed. When the heater is in the manual mode, the optional thermostat will not properly control the unit. When adjusting the Draft Fan setting, try only 1 setting above or below the heat setting. It is better to leave the stove in the automatic mode and adjust the manual draft slide to control the combustion air.

The room fan will come on once the unit has reached operating temperature (110°F). By pressing the “Room Fan” buttons, the display will show “Rf-A” which is automatic or "Rf-1" through "Rf-9" for manual settings. In auto mode, the room fan’s speed will automatically be adjusted in accordance with the heat range setting. By pressing the “Room Fan” up arrow, you can adjust the fan speed setting up to "Rf-9". The fan speed can be adjusted to a higher setting than the heat setting but not lower.

The “Aux” button is for Agitator operation. When the unit is “OFF” and the stove is cool, pressing the “Aux” arrows will rotate the agitator for easy removal for cleaning. The agitator, when in Automatic mode, will operate at set intervals. However, these can be changed by pressing the arrows on the “Aux” button. The agitator can be adjusted from 0 to 9, setting “0” is off and setting “9” is high.

The “Auger Delay” button can be used to pause rotation of the Auger and Agitator for approx. 1 minute. This can be cancelled by pressing the “ON” button. The “Auger Delay” is normally used only during the start up cycle to slow the fuel delivery down during the initial ignition.

The “Mode” button is used to switch between manual and automatic mode. When in auto mode, the fan, auger, and agitator will operate at preset intervals unless changed manually using the buttons mentioned above. When in manual mode, the draft fan (exhuast) will operate at full speed (100%), so the air must be controlled with the manual slide damper just below the viewing door.

During normal operation, the unit is constantly monitored for problems. In the event of an error condition, the unit will stop and an error will be displayed. See the list of error codes found at the end of this manual.
