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 auto-

matically 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 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 (Fig. 1). The unit's maximum 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 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 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 

regardless of room temperature (See Fig 4). The unit's 

maximum 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.

Automatic Ignition/Operation

Fig. 4

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.
