Harman Stove Company The Harman Accentra Pellet Insert - Manual (Page 4)

5
The Accentra 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
Accentra 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 au-
tomatically by the Room Sensing Probe. When the Room
Sensing Probe calls for heat, the stove will increase out-
put. When the Room Sensing Probe is getting close to
the set temperature, the stove will begin to level off out-
put and keep the fire burning at just the right temperature
to maintain that setting.
High output is determined by the feed rate set-
ting. This setting, generally on #4, can be increased if
higher burn rates are necessary (Fig. 1). The unit's maxi-
mum burn rate should not create less than 1" of ash on
the burn pot front edge(See Fig.2). Overfeeding is not a
safety concern, but fuel may be wasted if unburned pel-
lets 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 automati-
cally.
The distribution blower speed will vary according to
the position of the mode selector pointer, and fire size.

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 regard-
less of room temperature (See Fig 4). The unit's maxi-
mum feed rate should not create less than 1" of ash on
the burn pot front edge. See Fig 2.
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 automati-
cally.

Room Temperature M ode: 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.
