Harman Stove Company The Harman Accentra Pellet Insert manual Automatic Ignition/Operation

Automatic Ignition/Operation 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 roomsensor mode is recommended because of its efficiency. The unit can be switched between "AUTO" and "MANUAL" at any time during operation.

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.

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.

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 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 stopburning 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.
