Stainless steel ATTACK burner works on principle of fuel -pellet falling from fuel feeder through supply hose and pipe on the grate to be combusted.

Burner works under fully automatic mode, from evaluation of heat supply need, fuel supply, electrical ignition, burning-up, burning, shutting-down, burning-out, cleaning and switching to the emergency regime.

Burner output is of the range of 8–30 kW, adjustable by 2 kW. Burner output range of 14–30 kW is set from production. There are three levels of output: 1 (14 kW), 2 (22 kW) and 3 (30 kW). Output range of two levels: 8–12 kW and 14–30 kW can be set in the advanced menu.

Burner is cleaned automatically – after every burning out or in particular time intervals, set by the user, the grate is cleaned by automatic movement towards the scraper. Dirts like ash and eschars fall out of the opening of the grate.
Burner body, grate, tinplate of ignitor and scraper are made from high quality refractory stainless steel.
