Page 4 ATTACK DP wood gasifying boiler is designed for economic and ecological heating of family houses, bungalows, small plants, workshops and similar objects. Specified fuel for ATTACK DP boilers is dry wood, e.g. logs of lengths, depending on the type of boiler. The wood gasifying boiler is the holder of 101 5 certificate.

Page 8 ATTACK DP Profi The asset of Profi version of ATTACK DP boilers comparing with Standard version is in more comfortable service and the possibility of heat output modulation and addition of control elements. The boiler temperature is kept at the level set by the user, by setting up number of revolutions of the flue gas fan.
Page 9 Purpose of use Ecological hot-water boiler Attack DP is designed for heating of family houses and similar objects. The boiler is designed for burning wood only. Any dry wood can be used for burning, mainly logs. Also wood of bigger diameter, blocks, can be used, which reduces nominal output but prolongs burning time.
Page 10: Warning
Warning After the first heating up, there can be condensation and condensate may leak. This is not a defect Condensation disappears after longer heating. When burning smaller wooden waste it is necessary to check the temperature of flue gas which must not overcome 320°C.
Page 11: Technical Description Of Dp Profi
Technical description of ATTACK DP PROFI: During the operation, the display is showing the current temperature of outlet heating water. Speed of the fan are controlled in this way: - if during burning up proces the boiler temperature is lower than 45 °C, the fan works with the...
Page 12 Overheating of the boiler If the temperature of the boiler raises to more than 95 °C, the regulator stops the flue-gas fan and the control light of boiler overheating shines on. For new start it is necessary to: wait until the boiler temperature falls remove the cause of boiler overheating (e.g.

Page 14 Note Logs of bigger dimensions is necessary to cut into halves or quarters (because of the requirement of operation to nominal output). You can burn hard as well as soft wood. Wood must be dried! Boiler output depends on the moisture content of wood. Output and function of the boiler is guaranteed for maximum moisture content of 20%.
Page 15: Protection Of Boiler Against Corrosion
Protection of boiler against corrosion Suitable solution to this problem is mixing appliance (Regumat ATTACK-OVENTROP) or a thermoregulation valve which enables separated boiler and heating circuit. This way you can prevent undercooling of boiler under 65°C and also decrease condensation of steam, acids and tars in the feed hopper.

Page 17 460 l (STN EN 303-5, clause 4.2.5 ). Protection and usefull life extention of the boiler 1. ATTACK Oventrop keeps the temperature of return heating water coming to the boiler on °C . Temperature of return heating water under 60°C causes the condensation of steams, acids and tars in the feed chamber and it is the reason of the boiler usefull life shortening.
Page 18: Protection Of Boiler Against Overheating
2. Connection with threeway thermoregulation valve Operational principle is the same as the connection with ATTACK Oventrop regulation system. When the temperature is higher that 65°C the thermoregulation valve opens the circuit in heating system. When the temperature is lower than 65°C makes this circuit closed and the boiler works in the short boiler circuit.
