THE SLIDER / DAMPER MUST BE SET AT TIME OF INSTALLATION, IT IS USED TO REGULATE
THE AIRFLOW THROUGH THE PELLET STOVE.
A Qualified Service Technician or Installer must set the Slider Damper.
The slider damper should be set only on a hot stove (operating for thirty (30) minutes or more) by placing
a Magnahelic Pressure Gauge in the firebox (test port is located in the center of the stove just below
the door opening). Set the slider damper so that the pressure reads 0.11” w.c. (.028 KPa) on HIGH
A) HI / LOW: When the
jumper is placed on
only one of the J9 pins,
then the control board
is in a HI / LOW mode
of thermostat operation
(factory setting).
Remove jumper wire and install thermostat
wires here
ON / OFF OPERATION: If
the control board is placed with
J9 jumped then the control
board is in a ON / OFF mode
of operation. In the ON /OFF
thermostat mode, when the
thermostat calls for heat, the
unit will go through an ignition
sequence and light the stove.
Once lit the unit will operate at
the selected setting displayed on
the control board Heat Output
Indicator. Once the thermostat
stops calling for heat, the unit
will stop feeding pellets and
begin its shut down sequence
until cold then turn off.
1. Install the Low Voltage
Thermostat (maximum
24V) in a location that is
not to close too the unit but
will effectively monitor the
desired area to be heated.

B) ON / OFF: If both
pins of J9 are jumped
(covered), the control
board is in an ON / OFF
mode of thermostat
operation.

This control board can be placed into two (2) different modes:
HI / LOW OPERATION: When the jumper J9 is not jumped then the control board is in a HI / LOW
mode operation. If the unit has been placed in the HI / LOW mode, the unit will be taken to a low or
idle setting when the thermostat is not calling for heat. When the thermostat calls for heat, the unit will
go to the setting that is displayed on the control board Heat Indicator. If the heating load is not great
enough when the stove is on low, the high limit switch will turn the stove off and the switch will have
to be manually reset. To reset the high limit switch, remove the right cabinet side. The switch is found
behind the control panel. Avoid setting off the high limit switch.
