Thermostat Operation:
Once installed, the thermostat can control the operation of the stove. Use a low voltage/millivolt thermostat.
(See "Optional Thermostat installation" on page 22) for installation instructions.
Important: When connected to a thermostat, it is necessary to push the ON/OFF button for the initial burn,
when the electrical flow to the stove is interrupted, or if the stove runs out of pellets and therefore shuts off
with a fault code.
• Manual Mode:
After the stove is burning (See "Opening the Door." on page 9), the heat level setting controls the
pellet feed rate and the stove’s heat output. Once set, the stove will continue to burn at this rate until the
heat level is changed or the stove is shut off.
• HI/LO Mode:
After the initial ignition sequence, when the thermostat calls for heat (the room temperature is less than
the temperature set on the thermostat), the stove will burn at the heat level setting. The higher the set-
ting, the quicker the room will heat up. Once the thermostat no longer calls for heat (the room is up to the
desired temperature), the stove will drop down to burn at the lowest HEAT LEVEL setting. This cycle will
continue until the stove is turned off or runs out of fuel.
• AUTO Mode:
When the thermostat calls for heat (the room temperature is less than the temperature set on the thermo-
stat), the stove will burn at the heat level setting. The higher the setting, the quicker the room will heat up.
Once the thermostat no longer calls for heat (the room is up to the desired temperature), the stove will
drop down to burn at the lowest HEAT LEVEL setting. The stove will continue to burn for 45 minutes at
the lowest setting. If the thermostat does not call for heat again during that time, the stove will shut off. It
will relight when the thermostat calls for heat. If, during that 45 min., the thermostat calls for heat again,
the stove will again burn at the HEAT LEVEL setting until the thermostat no longer calls for heat.
Damper Adjustment
The Damper is used along with the Combustion Blower control to regulate air flow through the stove.
THE DAMPER MUST BE SET AFTER INSTALLATION, DURING THE FIRST FIRING. This procedure
should be done by a Qualified Installer or Service Technician. (See "Setting the damper" on page
23)
Because of the differences in pellet quality, the Damper may need to be adjusted from time to time. If the
stove goes out contiually on low, the unit may need to have the damper closed slightly for reduced airflow at
the lower heat settings. If the stove continually buids up with ash/clinkers in the liner the damper may need
to be opened slightly for more airflow through the liner.
