The Accentra 52i Pellet Insert 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 Pellet
Insert 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.
NOTE:
At the end of the season the best way to shut down
the stove is simply let it run out of pellets, then the stove will
shut down automatically.
Room Temperature Mode:
This setting will produce a room
temperature of 70 degrees with the distribution blower at medium
speed.
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.
