Purpose of usage 
Ecological warmwater boiler 
Ecological warmwater boiler Attack DPX is designed for heating of dwelling 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.  The boiler cannot be used  for  burning filedust and small  wooden  debris. 
This can be burnt only in small amount together with logs (max. 10%). Due to its large feed hopper 
you  can  avoid  the  most  demandable operation  of  preparation  and  cutting  the  wood  into  smaller 
pieces.Location of the boilers in living spaces (including halls) is inadmissible! 
Technical description 
The boiler is designed for combustion of wood on the principle of wood gasifying using a flue gas 
fan sucking flue gas from the boiler. 
The body of the boiler is a weldment of metal steel plates of 6 mm thickness. It includes a feed 
hopper with a  heatproof shaped piece that has an oblong opening for transition of flue gas and gas. 
Under it in the after-combustion space there is an ash pan  In the  rear part of the boiler there is 
there is a pipe exchanger with turbulators joined by vertical flue channel with a fuel cut-off flap in 
the upper part. There is also a suction branch for connection to the flue. 
In the front wall in the upper part there is a feeding door and in the bottom part there is an ash door. 
Between the door, under the front cover is the flap of the primary and secondary air.  In the left 
cover, in the level of the feeding door, there is a pull rod of the heating up flap controlled by the 
door and the exchanger cleaning lever. 
 The  body  of  the  boiler  is  from  the  outside  insulated  by mineral  fleece  put  under  the  covers  of 
outside  jacket.In  the  upper  part  of  the  boiler  there  is  a  control  board  for  electromechanical 
regulation.

Operation prescriptions 
Preparation of the boiler for operation 
Before  putting  the  boiler  into  operation  make  sure  whether  the  system  is  filled  with  water  and 
deareated.  Make  also  sure,  that    it  does  not  come  to  decrease  of  heating  water  pressure.  Check 
sensors of boiler, safety  thermostats and manometer, placed in  casings in the rear  boiler part, 
rearward. Check tightness and construction of flue gas ducting. The boiler can be operated only in 
accordance with these instructions in order to work properly. It can be operated only by an adult. 
When  installing  the  boiler,  lay  something  under  the  rear  part  to  elevate  it  in  10  mm  for  better 
flushing and deareating. Boiler must be attended only by the trained adult person with completed 
elementary education. 
Attention 
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. Otherwise the fan can be
