This heating appliance does not just have automatic ignition, it has total automatic temperature control. The

Accentra has an input heat range from 0 to 40,000 BTU's.  This patented feed system has a maximum feed rate of 5 lbs.
per hour and a minumum (maintenance) feed rate of .75 lbs. per hour and then "off" if necessary. The hopper holds
approximately 50 pounds of fuel. The unit has an easy to clean combustion system with an ash pan that holds ash from
1 ton of burned premium pellets.
The control is designed for easy and efficient operation. It has 2 automatic modes of operation and 2 manual modes of
operation.

The Accentra uses a small room sensor rather then a wall thermostat for a more accurate temperature control.

This unit is equipped with several different safety devices which will be explained later in this manual.With its specially
designed burn pot and the "Advance Ignitor" Automatic Ignition System, the unit can burn a large variety of biomass fuels
with varying ash content. The accordian style cast iron heat exchanger system allows maximum surface area for the
most efficient heat transfer in a smaller firebox.
