Fuel is burned in the stainless steel burner, intended for combustion of the wood pellets. Fuel is automatically ignited by electrical spiral, built into the burner. Optimal burning conditions and output regulation are provided by electronically controlled fuel feeding and air inlet, following the parameters of heating and d.h.w. warming, required and set by the user. Burner, combustion chamber and exchanger are constructed to ensure optimal burning of all combustible materials. Boiler body is isolated with mineral wool, design is completed with powder-treated coating.
SMART Boiler control
The ATTACK PELLET 30 AUTOMATIC Plus pellet combustion boiler is controlled by a clear, fully graphics 4.5” touch screen on the upper covering plate of the boiler. The new control allows to expand with an internet module * through which the boiler can be connected to WIFI or LAN and controlled using a mobile device or computer (* optional accessory).

Basic part of the boiler is a water cooled boiler body. Welded piece of the body is made from special boiler steel plates of 6 mm thickness, which guarantees long lifetime of the boiler. Exchanger is tubular, with turbulators improving heat transfer into the heating water and enabling exchanger cleaning to ensure balanced efficiency.
The boiler is equipped with spiral fuel feeder (1,5 m), ensuring continual fuel dosing. The ATTACK Pellet 30 Automatic Plus boiler can be delivered with pellet container of 450 l volume (dimesions: 1.024 x 705 x 830 mm). The „big-bag“ – the external textile tank can be used as an alternative.
The ATTACK Pellet Automatic Plus boiler is equipped with automatic system for ash removing into detachable box. Box of appropriate volume has to be emptied one time pro heating season, according to the season and intensity of boiler operation. Boiler can be also accessorized with electrical heating device of 2,4–6 kW output.
Boiler constructively consists of combustion chamber with partitions and tubular heat exchanger. Beyond the heat exchanger, the flue gas goes into collector with chimney, that can be horizontally or vertically oriented by turning the flange for 180°C. There is a wood pellet burner built-into the boiler body.
FUEL – PELLETS
The pellets are a by-product of wood processing. Their advantage is the extreme density and very low water content. They are used as a substitute to fossil fuels in boilers, furnaces and fireplaces are quality and environmentally friendly fuel. Their properties make them suitable for use in boiler rooms with automatic operation.
By wood pellets combustion in the ATTACK boiler, there is minimal ash production. Amount of ash depends on quality of pellets and represents approximately 1 % of the consumed fuel. Recommended fuel for the ATTACK Pellet 30 Automatic Plus are wood pellets with max. humidity of 12 %, diameter of 6 – 8 mm and max. length of 35 mm. Recommended ash content is 1 %. Heat value of the prescribed fuel should be 15 – 17,5 MJ / kg.
