ATTACK DPX – THE WOOD GASIFYING BOILER
Installation, heat-up test and user training must be performed by the technician trained by
producer. The technician must fill the protocol about the installation of the boiler.
By gasification of wood it comes to creation of tar and condensates (acids) in the fuel tank.
Due to this there must be a mixing device installed behind the boiler to keep the minimum
temperature of return water at 65 °C. The temperature of water in the boiler during its
operation must be within the range of 80 – 90 °C.
The boiler must not be permanently operated within the output lower than 50 %.
If the circuit pump is being used, its operation must be controlled by a separate thermostat
to ensure the prescribed minimum temperature of the return water.
Ecological boiler operation is related to its nominal output.
It is recommended to install the boiler together with the accumulation tank and mixing
device. This ensures the fuel saving of 20–30% and longer lifetime of the boiler and chimney.
If it is not possible to connect the boiler to the accumulation tank, it should be connected
with at least one equalization tank with the volume of approximately 25 l / 1 kW of the
boiler´s output.
By the operation with lower output (summer operation and D.H.W. preparation) it is
necessary to heat the boiler up every day.
Only the dry fuel of 12–20 % moisture can be used (by the higher moisture of fuel is the
boiler output decreased and its consumption increased).
The DPX boiler liner is equipped with the tubular exchanger, except of the 15 DPX boiler.
Tubes in the exchanger of the 15 DPX are cleaned by an appropriate kit delivered together
with the boiler.
Due to the economical operation and correct functionality it necessary to choose an
appropriate boiler output. The nominal output of the boiler has to be adequate to the
temperature loss of the heated object.
The boiler must be used only for the purpose that it is intended for and only in the way
given in this manual.
CAUTION – After disconnecting the boiler from electricity mains there is still fuel
burning. Do not open the boiler door until the temperature decreases below 40 °C.
The warranty for the boiler is not valid:
if it is not operated with the prescribed fuel – i.e. wood with the moisture lower than 20 %
if no mixing device Regumat ATTACK-OVENTROP is installed in the system to ensure the
return water temperature of at least 65 °C during the boiler operation

5
if no functional thermostatic valve is installed on the aftercooling circuit (WATTS STS20) of
the boiler, connected to the cold water inlet.
This device is not supposed to be used by persons (including children) with physical, sensual or
mental disability or insufficient experience due to which they are not able to use the device in a
safe way without being supervised or instructed about the boiler operation by the person
responsible for their safety. Do not to allow the children to play with the device.
If the power supply cable is damaged, it must be replaced with a special cable available by
producer or by a service technician!
Be careful by work with device! The Lambda sensor works by high temperatures (300 °C)
and there is a danger of getting burnt if you are not careful enough!
The warning sign
This warning sign appears in the manual when the health or property is threatened, in case that
the instructions are not exactly kept.
Two types of the warning signs and symbols are used in this manual:
WARNING – Information about the potentially dangerous situation that could cause
serious threat to health or property if advised actions are not taken.
CAUTION – Warns about the less safe way of work and procedures that may cause health
injury of material damage.

temperature decreases below 85 °C, it is necessary to undo the reset cover and to press the
restart button manually.
2. Fuse – boiler protection against short circuit
3. Main switch – boiler start and stop for the case of need
4. Flue gas thermostat – the fan is stopped after the flue gas temperature decreases below
the adjusted value
ATTENTION! Set this thermostat to 0 °C by heating up. After the fuel starts to burn, set the
flue gas thermostat to the „Operation“ position. When the temperature decreases under
the adjusted value, the exhaust fan is stopped. To start the fan again, set the lower
temperature value on the thermostat. The optimal setting for operation will be found by
experience.
5. Boiler thermostat – serves to set the max. temperature of water in the boiler (After
exceeding the adjusted temperature is the fan stopped and the boiler works at min.
output. After the temperature decreases below the adjusted value, the fan is started again
and the boiler works at max. output).

1.6 PURPOSE OF USE
The ecological warm water boiler ATTACK DPX is intended for heating the family houses and
other similar objects. The boiler is designed only for the use of wood logs. Any type of dry wood
can be used, especially the wood logs. It is also possible to use the blocks of wood with larger
diameter – then is the boiler output lower, but the time of burning is longer. The boiler is not
suitable to burn the saw dust and small wooden waste. Only small amount (approximately 10 %)
of such a material can be used together with the wood logs. Thanks to the voluminous feeding
chamber it is not necessary to do the most demanding work with wood – chopping into smaller
pieces.
It is not allowed to place the boiler in residential premises (including corridors)!
1.7 TECHNICAL DESCRIPTION
The boiler is designed to burn wood on principle of the wood gasification by using the exhaust
fan that sucks the flue gas from the boiler.
The boiler body is welded from the steel plates of 6 mm thickness. In the feeding chamber there
is a fireproof nozzle with longitudinal opening for the flue gas and gas passage.
In the burning chamber there is a fireproof ashtray. In the rear part of the boiler body is the
tubular exchanger with the flue gas collector and the heat up flap in the upper part. There is also
the flue connection in the rear part.
In the front parts there is a feeding door and at the bottom there is the ashtray door.
Between the doors there are the primary and secondary air inlets placed under the boiler
covering.
In the left covering at the same level as the middle of the feeding door there is a pull rod of the
heat up flap that is controlled by the feeding door and there is also the lever for exchanger
cleaning. The boiler body is insulated by a mineral wool, inserted under the external covering.
The control panel for electromechanical regulation is placed in the upper part of the boiler.

2TECHNICAL DESCRIPTION OF THE ATTACK DPX STANDARD
2.1 OPERATING PRESCRIPTIONS
Boiler preparation for operation
Before starting the boiler, it is necessary to check that the system is filled with water, deaerated
and the pressure of heating water does not decrease. Make sure that the sensors of the boiler,
safety thermostat and manometer are placed in casings on the upper rear side of the boiler.
Check the tightness and construction of the flue connection. The boiler has to be operated in
line with the instructions given in this manual to achieve its good service. By boiler installation
you can underlay it for 10 mm to enable better flush by water and deaeration. Only an adult
trained person with completed elementary education can operate the boiler.
Caution
By the first heat up it may come to condensation and leakage of the condensate – it is not a fault.
There will be no more condensate after heating for a longer time. In the case that the smaller
wooden waste is being burned, it is necessary to check the flue gas temperature which should
not exceed 320 °C. Otherwise it could damage the fan. By the gasification of wood it is normal
that tar and condensates are created.
If the boiler has been out of order for a longer period, it is necessary to be more careful by
starting it again. It could come to the pump blockage, leakage of water from the system or to the
boiler freezing in the winter.
Heating up and operation
Before igniting the fuel, open the feeding door and push the pull rod of the heat up flap back to
the basic position until is the latch fixed (like when the door is closed, see the picture).
Position after the feeding door is open.
Press backwards and downwards
Position after pressing backwards and downwards
Turn the flue gas thermostat to „0 °C“. Put one layer of the medium thick wood logs ( of approx.
50 mm length) through the upper door on a fire proof nozzle. Then, make the layer of thin wood

13
with the gap of 2–4 cm and lay splinters or wood wool and paper on it. Continue with 2 layers of
thin dry wood and complete it with the standard firewood. Turn the exhaust fan on and after the
wood is ignited, let the feeding door open for approximately 15 mm. Use the output regulator to
set the required water temperature (80–90 °C). When the fire is strong enough (after
approximately 10 minutes), close the feeding door. Set the flue gas thermostat to the operating
temperature (white mark upwards, approximately 90° to the right from the zero position – it
depends on the flue gas temperature required to stop the boiler after the fuel burns out).
WARNING: The pull rod of the heat up flap has to be pushed backwards to close the
heat up flap. Otherwise the fan could get damaged.
For wood gasification in the boiler it is necessary to keep the reduction layer during the
operation (the layer of wood coal on the nozzle in the feeding chamber). Therefore it is
necessary to burn dry wood of a suitable size. When the wet wood is burned, the boiler does not
work as a wood gasifying boiler, the wood consumption rises, the output is not sufficient and
service life of the boiler and of the chimney is shortened.
When there is a prescribed chimney draught, the boiler works up to 70 % of its output even
without the fan.
Electromechanical boiler regulation
The boiler is regulated by the boiler thermostat placed on a boiler panel which controls the fan
according to the adjusted output temperature of water. The required operating boiler
temperature should be set on the boiler thermostat. The flue gas thermostat placed on a panel
serves to stop the fan after the fuel burns out. Set the flue gas thermostat to “0 °C” when heating
up. When the fire is sufficient, set it to the operating position to let the fan run and to stop it after
the fuel burns out. The optimal position of the flue gas thermostat has to be found by
experience, adequately to the fuel used, chimney draught and other conditions. The output
temperature of water is indicated on thermo-manometer. The irreversible safety thermostat is
also placed on the front panel (the STANDARD and LAMBDA version).
Refilling the fuel
When refilling the fuel, open the feeding door. The heat up flap is opened at the same time. Do
not stop the fan. Always keep the feeding chamber full when heating up. Not to let the smoke
flow into the boiler room, refill the fuel after it is burned to approximately 1/3 of the feeding
chamber. Cover the glowing coal with a wide wood log and refill the fuel normally. Do not press
the fuel on the nozzle, otherwise it could get clogged and the parameters of burning would be
worse.
