E. Automatic Ignition
Room Temperature Mode: This setting will produce a room temperature
of 70 degrees with the distribution blower at medium speed.
Stove Temperature Mode
This setting will produce medium heat with the distribution
blower on "low".
This setting will produce continuous maximum heat output
with the distribution blower at full speed.

The XXV Pellet Stove is more than just automatic ignition, it
is also automatic temperature control. The automatic system
will allow the fire size to be adjusted to match the heating
needs and even put the fire out if necessary. If heat is needed
after the fire is out, the XXV Pellet Stove will automatically
re-ignite and adjust the fire size to match the heating need.
The totally automatic room sensor mode is recommended
because of its efficiency. The unit can be switched between
"AUTO" and "MANUAL" at any time during operation.
Igniter switch to "AUTO"
Room Temperature 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 #4, can be increased if higher burn rates
are necessary (Figure 4.6). The unit's maximum burn rate
should not create less than 1" of ash on the burn pot front
edge (Figure 4.7). Overfeeding is not a safety concern, but
fuel may be wasted if unburned pellets fall into the ash pan.
In "Room Temp Mode" a constant fuel consumption rate is
sacrificed for exact room temperature. Therefore, as it gets
colder more pellets 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 Temperature 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 maximum feed rate should not create
less than 1" of ash on the burn pot front edge. Figure 4.7.
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.
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 simply let it run out
of pellets, then the stove will shut down automatically.
