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 6041I is located on the left facade.
This unit has two fuel operation modes for different fuels, corn or pellet. It may also
be changed between an automatic operation or a manual operation in either of the
fuel modes. The heater comes from the factory in the corn mode.
Pressing the “ON” button on the control panel will begin the start-up sequence for the
heater. The start-up sequence differs depending on which fuel operation mode you
select. See Lighting Instructions for details. 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 re 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 adjusting the Draft Fan setting, try only
1 setting above or below the heat setting. It is better to leave the heater 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 (approx. 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 than the
corresponding heat range.
The “Aux” button is for Agitator operation. When the unit is “OFF” and the heater 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
(exhaust) will operate at full speed (100%), so the air must be controlled with the manual slide damper just below the viewing door.
When the heater is in the manual mode, the optional thermostat will not properly control the unit.
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.
