The burner is designed for ATMOS D80P, P80 special boilers. ATMOS burner A85 is equipped with pneumatic cleaning which cleanses the burner’s combustion chamber after every burn out or at regular intervals. Thanks to pneumatic cleaning you can check or clean the burner’s combustion chamber only once in a fortnight or a month.
Heating with pellets with the use of the ATMOS A85 pellet burner has a lot in common with natural gas or oil heating.
However, there is a difference that burning of pellets produces a certain quantity of ashes that must be removed from the burner and boiler in an interval to avoid impairment of efficiency or affecting the functionality of the burner.
The ATMOS A85 pellet burner is supplied with automatic fuel ignition as standard. The assembly of the burner, external conveyor and fuel bin work completely automatically during operation and is controlled by an electronic control unit with the use of a flame sensor (photocell). In the burner body the fuel and combustion air are supplied in such a way to ensure maximum efficiency and environment-friendliness of fuel burning.
