Igniter Switch to "AuTO" / room Temp mode
In "Room Temp Mode" heat output is controlled automatically
by the Room Sensing Probe. When the Room Sensing Probe
calls for heat, the stove will increase output. When the Room
Sensing Probe is getting close to the set temperature, the
stove will begin to level off output and keep the fire burning
at just the right temperature to maintain that setting.
High output is determined by the feed rate setting. This
setting, generally on #2 (corn) or #4 (pellet), can be increased
if higher burn rates are necessary.
When burning corn the feed rate setting can be adjusted
anywhere within the yellow range with a #3 setting being the
maximum setting, #1 the lowest setting. This setting will vary
depending on the quality of corn used.
When burning pellets the feed rate setting can be adjusted
within the full range between #1 on the low side to #6 on the
high side.
Overfeeding is not a safety concern, but the fire may be
pushed off the burnpot and extinguish in the ash pan.
In "Room Temp Mode" a constant fuel consumption rate is
sacrificed for exact room temperature. Therefore, as it gets
colder more fuel will be burned automatically.
The distribution blower speed will vary according to the
position of the mode selector pointer, and fire size.
Igniter Switch to "AuTO" / Stove Temp mode
This allows for automatic ignition upon start-up only. The unit
can then be set at any desired setting. The heat output and
fuel consumption will remain constant regardless of room
temperature.
The unit's low burn or maintenance setting is as low as it will
go. It will not go out unless it runs out of fuel or is turned off.
Shut-down Procedure
To kill the fire or stop burning the stove, turn the Mode
Selector to "OFF". This will cause the fire to diminish and
burn out. When the fire burns out and the stove cools down
everything will stop. NOTE: The combustion blower motor
will be the last component to stop. This insures that all
fuel in the burnpot and ashes located in the ash pan are
completely cold before shut down of the combustion motor.
If you pull the plug to shut down the stove, all motors will stop.
This may cause incomplete combustion and smoke in the
firebox. If the load door is opened the smoke may escape.
The best way to shut down the stove is to simply let it run out
of fuel, then the stove will shut down automatically.
