Manual Operation
After the stove is burning (see lighting instructions on Page 19), the heat
control dial controls the pellet burn rate and the stove's heat output. Turn-
ing the dial to the low setting allows the stove to burn about 1.8 pounds
of pellets per hour. Turning the dial to high allows the stove to burn 4.9
pounds of pellets per hour. Once set, the stove will continue to burn at
this rate until shut off.
Thermostat Operation
This stove will operate with a low voltage thermostat. See Page 11 for
instructions on installing the optional wall thermostat. Once installed, the
thermostat will control the operation of the stove.
IMPORTANT: When connected to a thermostat, it is necessary to turn
the heat control dial to your desired heat setting for the initial burn. After
the initial ignition sequence, when the thermostat calls for heat (the room
temperature is less than the temperature set on the thermostat) and the
heat control dial is not in the off position, the stove will burn at the heat
control dial 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 continue to burn for one additional
hour at the lowest setting. If the thermostat does not call for heat again
during that hour, the stove will shut off. During that hour, if the thermostat
calls for heat again, the stove will again burn at the heat control dial setting
until the thermostat no longer calls for heat. If the stove shuts off after
that hour it will relight when the thermostat calls for heat.

1. The stove has been switched on to your desired heat sequence #1 through #5.
Your stove is in IGNITE/START-UP mode which is a preset sequence which
will run 11 to 20 minutes and will switch to NORMAL HEATING mode when
sufficient temperature has been reached.

3. The hopper lid switch circuit is open which indicates the hopper lid is not
properly closed during the ignition sequence. If the hopper lid remains open,
the shutdown cycle will start within the time indicated on the display screen.
See Page 32 for more information about the hopper switch.

4. If the hopper lid remains open for more than 45 seconds the stove will enter
it's COOL DOWN mode followed by the FINAL SHUTDOWN mode. To reset,
turn the heat control dial to off and then back on to your desired setting. See

5. Your stove is equipped with a heat limit switch which senses a rise in the
operating temperature and will reduce the feed rate accordingly. This usually
occurs when the stove is in the high burn setting with the convection blower
set to minimum (which isn't the most efficient combination). When the stove
cools down it will automatically re-enter NORMAL HEATING mode at the setting
indicated on the heat control dial.

6. The room has reached the temperature specified by the thermostat. When the
thermostat quits calling for heat, the stove automatically enters the THERMO-

STAT IDLE mode and drops to the low burn setting. If the thermostat does not
call for heat again within the next hour, the stove will enter the COOL DOWN
mode, followed by the SHUTDOWN mode. If the thermostat calls for heat at
any point in the thermostat idle mode, the stove will resume operation in the
NORMAL BURN mode specified by the heat control dial.
