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
Page 5
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 of 110 °C is the boiler disconnected from electricity mains). After the
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.

2 TECHNICAL 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
Page 13
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.

3.3 CONNECTION OF THE REGULATOR BY HYDRAULIC SCHEMES
The regulator can control several types of hydraulic schemes. Parameters in the service menu
must be correctly set adequately to the type of the hydraulic scheme.
Note: The additional thermal probe to control the additional output is connected by production
and it is rolled in the control panel of the boiler. To use the probe it is necessary pull it out from
the control panel through the prepared plastic bushing. This action can be performed only by a
qualified person or by a person trained by producer. The regulator is set by production for the
simple control of heating circuit following the scheme 3.1. On the below mentioned schemes
there is connection of the pumps and sensors. Correct connection of the pumps and sensors is

3.4 REGULATOR CONTROL AND OPERATING MODES
Turning on the controller is signalized by a brief switching on all the light indicators on display
to enable to check their status. If the regulator gets suddenly disconnected from electricity
mains (e.g. by power failure), it is switched to the last mode used, when the failure occurred. All
the settings made are saved even after the power failure.
The basic setting of the controller is the adjustment of the boiler temperature by the knob. Other
functions are controlled adequately to the service parameters set in the service menu.
The boiler is turned on by pressing the START (17) button that starts the fan. The STOP (16)
button switches the boiler off by turning the fan off.
The sign displayed behind the numeric temperature indication (7) is related to the current
mode of the PID PROFI regulator:
[50°–] – indicates the stand-by mode
[50 °C] – indicates the winter operating mode
[50 °C] – indicates the winter operating mode when the boiler temperature is achieved
[50°U] – indicates summer operating mode intended only for D.H.W. preparation
[50°u] – indicates summer operating mode when the boiler temperature is achieved
[70°d] – indicates mode of elimination the legionella bacteria, when the temperature of D.H.W.
is increased to 75 °C
[50°P] – indicates that regulator is blocked by pellet burner of the COMBI PELLET boiler
The PROFI PID regulator has an advantage of regulating the flue gas temperature to the required
value.
The controller struggles to achieve the adjusted flue gas temperature and after it is achieved, the
required boiler temperature is to be reached. Thereby is the fuel used in the best way and the
high efficiency is achieved.
When loading the fuel, it is necessary to hold the START button (for approximately 3 sec.).
Rotations of the fan are increased to 100 %. Therefore it is ensured that the flue gas created in
the loading chamber is sufficiently sucked and no smoke gets into the boiler room. The fan gets
back to the regulation of rotations after the period defined by the parameter Md3.

[C 45] – Adjusted boiler temperature – this is the value of boiler water temperature the
regulator is going to reach while in the WORK mode. It is set by turning the thermostat knob
manually (8) and shown briefly on the display (6).
[co C] – WINTER/SUMMER mode – the winter mode is indicated by the ‘C’ letter. Then is the
circuit pump controlled by the room thermostat and distributes the heat into the heating
system. The summer mode is indicated by the „–“ sign. Then is the circuit pump out of order and
the heat generated by boiler is only used to heat the D.H.W. tank. If there is not D.H.W. tank in
the system (additional sensor is not connected), it is not possible to select the SUMMER / WINTER
mode.
[cu u] – Mode of D.H.W. tank warming – the regulator enables the casual D.H.W. tank warming
„u“ or the mode to eliminate the legionella bacteria „d“. After the „d“ mode is selected, the
temperature of 75 °C is achieved in the D.H.W. tank. When this temperature is achieved, the
controller switches into the mode of the casual D.H.W. tank warming „u“. The option of
elimination the legionella bacteria is not available, if the additional outlet and sensor are not set
for the D.H.W. warming.
CAUTION! Not to get hurt by the hot water, it is recommended to set this mode, when
the D.H.W. is not being used (e.g. during the night).
[u50°] Temperature of additional sensor – this is the value of current temperature of the
D.H.W. tank or of the accumulation tank of the heating system. This temperature is not displayed

3.7 DESCRIPTION OF PARAMETERS
[Π100] Maximum fan output – the highest fan output possible
[n 40] Minimum fan output – the lowest fan output possible
[Πh 5] Ratio of changing the fan rotations – this parameter influences the fan rotations, if the
adjusted boiler temperature is going to be achieved in a short time. For example, if the value 4 is
set, the fan will work at full output [Π100] (if the function of flue gas temperature control is not
active), up to 4 degrees before achieving the required boiler temperature. Then, by every
increase of the boiler temperature for 1 °C, the fan rotations are gradually decreased until the
minimum fan output is reached [n 40].
[Πr 0] Automatic regulation of changing the fan rotations – the fan rotations are increased /
decreased by setting this parameter within the range of 0–10 to ensure the required boiler
temperature. If this parameter is set to „- -“, the rotations are not controlled and the fan works at
full output according to the parameter [Π100]. Setting the parameter within the range of 0–10
relates to the time period (in minutes), during which are the fan rotations gradually increased
from the parameter of the minimum fan rotations [n 40] up to the parameter [r 100]. This
ensures the fluent heat-up of boiler.
[Πn 5] Frequency of exhaust fan blow-through – this frequency defines, how often the fan is
started to the full output [Π100] to take the flue gas out from the boiler, if the fan was stopped
due to the boiler temperature achieved.
[Πu 6] Duration of exhaust fan blow-through – during this period must the fan exhaust the
flue gas following the parameter [Πn 5].
[r 100] Fan output by ignition – this parameter defines the fan output by boiler heat-up. If the
parameter " Πr " is set to [Πr 0], then this parameter is not available.
[rh 5] Hysteresis of boiler stop by ignition – defines, how many degrees before reaching the
required boiler temperature will be the heat-up phase finished or (if the flue gas temperature
sensor is connected), how many degrees before reaching the required flue gas temperature are
relevant to stop the heat-up phase. After deactivation of the heat-up phase there is a casual
operating mode.
[P 30] Temperature to start the circuit pump – if there is not D.H.W. tank in the system [ur 0] or
it is in the mode [ur 2], then the parameter defines the boiler temperature for starting the circuit
pump of the heating system. If the parameter is set to „- -“, then too low temperature does not
influence the operation of the circuit pump. Anyway, the pump is always started, when the
boiler temperature exceeds the parameter [H 85] of the maximum boiler temperature.
If there is accumulation tank in the system (parameter [ur 4]), then this parameter defines the
temperature measured in the accumulation tank by which is the circuit pump of the heating
system started.
[Ph 2] Hysteresis of circuit pump – defines the temperature difference under which must the
boiler temperature or temperature in the accumulation tank decrease in comparison with the
temperature defined by the parameter [P 30] to stop the circuit pump.
Page 25
25
[Pc --] Interval of unlock function of circuit pump –when controller is in the stand-by mode or
the room thermostat is disconnected, the circuit pump is started for 30 seconds after each [Pc --]
minutes to prevent the pump blockage caused by its inactivity. The unlock pump function is not
active, when the Pc is set to „- -“.
[ur 0] Operation of the additional output – this parameter defines the operating mode of the
additional output (pump for D.H.W. tank or accumulation tank warming).
[ur 0] Additional output without function – defines that the additional output and pump are
not connected and the additional output is not used in this case.
[ur 1] Priority D.H.W. tank warming – by this setting is the pump for D.H.W. tank warming
connected to the additional output and the sensor of D.H.W. is connected to the additional inlet.
Then, if the temperature in the D.H.W. tank decreases under the value of hysteresis
[uh 5] from the temperature adjusted [u 60], the pump of D.H.W. tank warming is started. After
the temperature in the D.H.W. tank reaches the set value [u 60], the pump is stopped. The pump
is also stopped, when the temperature in boiler is lower than the temperature in D.H.W. tank.
The [ur 1] mode means that the D.H.W. warming has priority, i.e. the pump of the heating circuit
is started after the D.H.W. is prepared.
[ur 2] Parallel charging the D.H.W. tank – similar principle as by the [ur 1], just the D.H.W. is
prepared by the parallel operation of the circuit pump of the heating circuit.
[ur 3] Unused
[ur 4] Charging the accumulation tank – due to this setting is the additional output used as
a pump to heat the accumulation tank and the additional sensor measures its temperature.
When the temperature in the boiler exceeds the hysteresis [uh 5] over the current temperature
of accumulation tank, the pump for charging is started. The pump is stopped, when the
temperature in the boiler is same or lower than the temperature in the accumulation tank, or
when the temperature in boiler decreases under the minimum boiler temperature defined by
the parameter [L 65].
[u 30] Operating temperature of the D.H.W. tank or accumulation tank – temperature to
control the additional output [ur ].
[uh 5] Hysteresis of the D.H.W. tank or accumulation – this parameter defines hysteresis of
the additional output [ur ].
[uP 5] Boiler temperature increase by D.H.W. preparation – this parameter is relevant, when
the additional output works under the mode of D.H.W. tank charging. It defines, for how many
degrees will the adjusted boiler temperature be higher than parameter [u 50] during the D.H.W.
tank warming.
[L 65] Minimum boiler temperature – defines the minimum boiler temperature that can be set
by a knob.
[H 85] Maximum boiler temperature – defines the maximum boiler temperature that can be
set by a knob.
Page 26
26
[h 2] Hysteresis of boiler temperature – defines the difference between the adjusted and the
current boiler temperature for which must the boiler temperature decrease to start the
controller again after the adjusted boiler temperature is achieved.
[A 99] Temperature of boiler overheating – defines the value of boiler temperature to activate
the alarm of the boiler overheating.
[Fd60] Duration of boiler stop by ignition and fuel shortage – this parameter defines the
maximum time between starting the controller by the START button and achieving the
controller´s operating mode (reaching the flue gas temperature of [c 90]). If the temperature of [c
90] is not reached during the heating up, the fan is stopped and the alarm FUEL (fuel shortage) is
displayed.
[Fb30] Duration of boiler stop by flue shortage and burn-down – the fuel amount test is
activated in the operating mode, when the flue gas temperature decreases under the parameter
[c 90] or (if the flue gas sensor is not connected) when the boiler temperature decreases under
the adjusted parameter [L 45]. If the temperature does not exceed the necessary limit during this
period, the controller displays FUEL alarm.
[Ar 0] parameter – indicates start of the automatic boiler (e.g. gas or pellet boiler). When the
controller is started and the boiler generates heat, the automatic boiler is stopped. Operation
of the automatic boiler is blocked by the controller in the operating mode. The automatic
boiler is started by controller, when the fuel is burned down in the boiler and the FUEL alarm
is displayed.
[Ar 1] parameter – indicates that the additional multifunctional output will be used for error
messages like boiler sensor failure, overheating or fuel shortage.
[c 240] Adjusted flue gas temperature – the controller will struggle to reach and to keep this
value. The flue gas temperature sensor is turned off, if this parameter is set to „- -“.
[c h5] Hysteresis of flue gas temperature – defines the difference for which must the flue gas
temperature decrease to increase the fan rotations.
[
c
t 5] Time constant of stabilization the flue gas temperature – defines the period of
adjusting the fan rotations during stabilization of the flue gas temperature. If the flue gas
temperature exceeds the value given by the parameter [
c
240], the controller starts to decrease
the fan rotations gradually, until the flue gas temperature decreases to the adjusted value. If the
flue gas temperature decreases to the value of flue gas temperature hysteresis, the controller
starts to increase the fan rotations gradually.
[c F10] Blower speed jump while stabilizing exhaust gas temperature – defines the change
of rotations to achieve the adjusted flue gas temperature.
[c 90] Flue gas temperature by fuel shortage – the message „FUEL“ for fuel shortage is
displayed after the flue gas temperature decreases under this value.
3.8 TESTING THE REGULATOR OUTPUTS
It is possible to make a check to test the correct functionality of the regulator and devices
connected. The correct function of fan is tested by selecting the [outΠ] on display and holding
the „OK“ button. Test of the circuit pump is done by selecting the [outP]. Select the [outu] to
start the additional output and [outr] for multifunctional additional output.

3.9 RESET OF THE REGULATOR´S PRODUCTION SETTINGS
There is a possibility to reset the production settings of the regulator by selecting the [Prod] in
the service menu and confirming by „OK“ button. Then is the regulator set to the values given in
the Table 3.
3.10 EXIT FROM SERVICE MENU
Select the [End] on display and press the „OK“ button to exit from service menu.
3.11 ERROR MESSAGES
The connection of all sensors of the regulator is permanently monitored. If the regulator detects
that some of the sensors is not connected, the error messages are displayed. Messages about the
boiler overheating or fuel shortage are also displayed.
Error messages displayed
[FUEL] – is displayed, when there is not enough fuel in the boiler. The sufficient amount of fuel is
defined by the parameter c90, where the figure 90 is related to the adjusted value 90 °C. Then, if
the flue gas temperature decreases under this adjusted value within the time Fb30 (time of
boiler stop by fuel shortage), the regulator displays the [FUEL] message. To start the boiler again,
it is necessary to remove the message by the STOP button and then to press the START.
[HOT] – is displayed, when the flue gas temperature exceeds the maximum permitted value set
by the parameter c300 (means 300 °C). The ventilator is stopped in this case. After the
temperature decreases under the adjusted flue gas temperature, the ventilator is started again.
[E 1] – is displayed, when the boiler temperature sensor fails or when it is not connected. In such
case is the regulator taking actions to ensure the safety of the boiler – the fan is stopped (if it is
currently in operation) and the circuit pump is started for eventual safe boiler cooling. After the
cause of error is removed, the error message can be erased by the STOP button.
[E 2] – is displayed, when the boiler temperature exceeds the boiler overheating temperature
A99. The regulator stops the flue gas fan and starts the circuit pump. The error message can be
removed by the STOP button after the boiler temperature decreases to the safe value.
[E 8] – is displayed, when the additional sensor fails (in the D.H.W. tank or accumulation tank). If
this sensor works for the D.H.W. tank, the warming is blocked. If the sensor works for the
accumulation tank, the pump will be permanently working. This error message cannot be
removed by the STOP button. It is automatically erased after the sensor failure is repaired.
[E128] – is displayed, when the flue gas temperature sensor fails. In this case is the boiler control
switched to regulate according to the boiler temperature. The error message is erased
automatically after the fault of the flue gas temperature sensor is solved.
[E 3] If several failures occur in one moment, their total is displayed. In such case it is necessary to
check the functionality of all sensors.

4 TECHNICAL DESCRIPTION OF THE ATTACK DPX LAMBDA
4.1 REGULATION OF BURNING
The boiler output is regulated according to the flue gas temperature by the air inlets to the
particular oxygen value. The flue gas temperature for burning down is adjusted. If there is a lot of
fuel (totally full feeding chamber) and the boiler temperature achieves 90 °C (overheating), the
flue gas fan is stopped, flap for primary air is closed and flap for secondary air is open for 25 %.
When the boiler temperature decreases to less than 88.5 °C, the flap for secondary air is for 30
seconds open for 100 % (chimney cleaning) and the primary air flap is regulated according to the
requirement for the flue gas temperature.
Automatic boiler stop: After the fuel burns out, the boiler can be stopped automatically or by
setting the flue gas temperature (TAG) or by a setting the value for oxygen (optional function).
Boiler stop by setting the flue gas temperature: When the fuel burns out and the flue gas
temperature decreases to less than 25 % of the adjusted value, the boiler stops after 15 minutes.
This is recommended only when the big or wet wood logs are being used.
Stop by the oxygen value: If the boiler works for more than 45 minutes and the oxygen value
exceeds 14 % for more than 15 minutes, then the boiler stops. This should be a standard function,
when the boiler cooling by chimney is limited. Ignition with remaining coal is easier and there is
less smoke by heating up.
When the boiler stops, the flue gas fan is stopped, the primary air flap is closed, the secondary air
flap remains open for 25 % until the flue gas temperature decreases below 100 °C.
Automatic restart after the power shortage: After the power shortage, the secondary air flap is
open for 100% for 30 seconds to let the chimney clean.
Overheating (boiler temperature above 90˚C): The secondary air flap remains open for at least
25 %.
After turning the boiler off (automatically or manually): The primary air flap V1 is closed (0%),
the flue gas temperature is above 100 °C, the secondary air flap remains open for at least 25 %
and function of the automatic operation is inactive.
4.2 IGNITING AND REFILLING THE FUEL
Basic instructions:
Check the pressure (and level of water) in the heating system before igniting.
The fuel has to be prepared in the boiler.
Ignite the fuel (see the prescriptions for boiler operation) and the rest of fuel in the feeding
chamber
4.3 IGNITING OR REFILLING THE FUEL
If it is possible due to the requirement for heat and the rest of the fuel in the feeding
chamber, check the thermometers in the feeding chamber.
Effect: Maximum utilization of fuel
Beginning: When the boiler is stopped (the indicator light 1 does not flash), make the fire as first.
4.4 REFILLING THE FUEL DURING THE BOILER OPERATION
Refill the fuel quickly and close the door immediately.
Page 30

4.5 FUNCTION AND DISPLAYING THE TEXT BY IGNITING OR
REFILLING THE FUEL
After pressing the „+“button it comes to the following procedure:
The boiler is started the indicator light 1 flashes and the ignition is running
The text is displayed:
DO NOT OPEN!
WAIT
the flue gas fan and regulation of burning are started
the supply pump and regulation of the return and supply valve are started
the generator of an alternative energy is stopped by the switch
after 5 seconds appears the text:
FUEL DOOR UNLOCKED
and in 10 seconds is the electromagnetic door-lock released (is it is disposable)
after 10 seconds appears the text:
CAUTION!
OPEN SLOWLY!
after 5 seconds appears the text:
IGNITION
Prepare and ignite the fuel following the instructions on the page 11, close the feeding door
partly. If the bar chart is full, the fuel is ignited, close the door.
If the bar chart is full and ignition or process of fuel loading takes more than 15 minutes, it is
switched to the operating display mode.
The regulator stops the boiler after 15 minutes, if:
There was no ignition and the regulator started the burning process despite of that fact,
because it was accidentally started by the „+“button.
The fire extinguished after closing the door, because there was lack of wood splinters or the
fuel is too wet.
4.6 DISPLAY OF THE OPERATING MODE BY THE BOILER STARTED
Text on display:

4.7 EXCESSIVE FLUE GAS TEMPERATURE
If the flue gas temperature exceeds 300 °C because the feeding door, the door for ignition or the
ashtray door was open for too long time, then appears the text excessive flue gas temperature –
(see display)
In this case: CLOSE THE DOOR IMMEDIATELY!
If the flue gas temperature exceeds 350˚C, the flue gas fan is stopped from safety reasons and
after the temperature achieves 299 °C or less, the flue gas fan is started again. Thereby is the flue
gas fan and the flue gas sensor protected against damage.
4.8 BOILER OVERHEATING
When the feeding chamber is totally loaded with too much of fuel, the boiler temperature rises to
90 °C and more. Then it comes to the state of overheating and the flue gas fan is automatically
stopped. Display flickers with the text:
Overheating
DO NOT OPEN
The boiler door must not be opened. By overheating it comes to the high fuel consumption and
ecological damages.
4.9 DISPLAY OF THE OPERATING MODE WHEN THE BOILER IS OUT
OF ORDER
When there is no more fuel left, the boiler is automatically stopped by regulator or it can be
stopped manually by the „+“button (this serves only for safety stop, e.g. when there is no water in
the boiler). After the boiler is stopped, the following text is displayed immediately:
BOILER TEMPERATURE
˚C
The display illumination is turned off after 15 minutes.
4.10 FUNCTIONS OF THE AUTOMATIC PROTECTION
If the boiler did not heat for 7 days, the flue gas fan is started for 2 minutes and the boiler is
„blown through“ by the fresh air to get dried. The reverse and supply valve are working as well
and the supply pump is started for 10 seconds. The following text is displayed during this
procedure:

4.16 MAINTENANCE OF THE HEATING SYSTEM AND THE BOILER
It is necessary to check, eventually to refill the water in the heating system at least 1x in 14 days.
If the boiler is out of order during the winter period and the water could freeze in the heating
system, then the water should be replaced with an antifreeze mixture approved by the producer
or it should be discharged out of the system. Normally should be the water discharged only in
urgent cases and for ash short time as possible. At the end of the heating season it is necessary
to clean the boiler properly and to replace the damaged parts. Twice a year it is necessary to
dismantle the fan, to clean the radial impeller and to clean the fan air chamber.
Exchange of the sealing cord of the door
Undo the worn sealing cord by the screw driver and clean the groove, where it was laid. Take the
new sealing cord and put its ends into the horizontal parts of the groove. Use your hand,
eventually a hammer to press the cord into the groove around the door.
Adjusting the hinges
After a particular period is the sealing cord in the door pressed. To ensure its tightness is
necessary to change the position of the door by screwing the door hinges. The feeding door and
the bottom door are fixed to the boiler body by two hinges that are connected to the door by
a long joint. To adjust the hinges, it is necessary to remove the joint and to turn and to screw the
joint. Fix the door and put the joint into the hinge.
Replacement of the nozzle
The nozzle is laid in the boiler body on the holder. In the bottom part is the nozzle sealed by
a boiler sealant and in the upper part there is a sealing cord around. When replacing the nozzle,
remove the sealing cord from the groove by a screw driver. Take the nozzle out and clean the
holder properly from tar and old sealant. Then treat the bottom part of the nozzle with the
fireproof sealant and put the nozzle on the clean holder with the arrow towards the rear boiler
part. There should be the same space on the both sides of the nozzle. Take the new set of the
sealing cords for the nozzle and press it lightly into the gap just around the nozzle.
Adjustment of burning in the boiler
The burning is adjusted by the primary and secondary regulation flap. Producer sets the boilers
to the optimum conditions of burning with reference to the emissions and flue gas temperature.
Only the service staff trained by producer can make the adjustment.
Optimum setting of the regulation flaps:
Primary / secondary air flap in [%]:
DPX15 – 100/25
DPX25 – 50/40
DPX30 – 50/25DPX35 – 50/50
DPX40 – 100/60
DPX45 – 100/60

2 – secondary air flap
Operation with permanent burning
It is possible to keep the permanent burning, i.e. the fire in the boiler for the whole night without
need to heat up during the day, but only in the winter period. For the operation with permanent
burning it is necessary to prepare the boiler in the following way:
Lay some bigger wood logs (4–6 pcs.) on a glowing layer of fuel
Close the mixing valve partly – temperature of water in the boiler achieves 80–90 °C
The regulation flap controlled by thermal regulator is automatically closed and the fan is
stopped.
After the boiler is prepared in this way, the burning is kept for more than 12 hours. When the
boiler is in the operation of permanent burning, the water temperature must be 80–90 °C.
Page 40

4.17 BOILER CLEANING
The boiler has to be cleaned regularly and properly, otherwise there is a risk of its wrong
functionality, shortened service life or damage.
Always clean the boiler when it is out of order. It is recommended to turn the exhaust fan on
while cleaning. Detailed description for boiler cleaning is given in the attached „Manual for
correct installation, operation and cleaning the boilers ATTACK DPX“.
The frequency of cleaning the particular boiler parts is given in the table below:
Cleaning*
Daily
Weekly Annually
Ash removing 1×
Space around the ash tray 1×
Space under the exchanger 1×
Lever of turbulators 5–6×
Flap 1×
Space of the fan 1×
Radial impeller of the fan 1×
* The minimum recommended intervals of cleaning. They can be shorter, according to the
intensity of operation.
ATTENTION – Regular and proper cleaning is important to ensure the permanent output and
service life of the boiler. The warranty is not valid if the boiler is not sufficiently cleaned and
damaged.
4.18 PRESCRIBED FUEL
The prescribed fuel is dry chopped and log wood with diameter of 80–150 mm, moisture of 12 %
(min.) – 20 % (max.) and heat value 15 – 17 MJ/kg-1. It is also possible to burn big pieces of the
wooden waste together with rough wood logs.
Note
The wood logs of higher diameter must be chopped to halves or to quarters (due to the
requirement for the boiler operation at nominal output). It is possible to burn soft or hard wood.
The wood must be dry!
The boiler output depends on the wood moisture. The boiler output and function are ensured
by the max. wood moisture of 20 %. The warranty is not valid if the boiler is operated with the
fuel of higher moisture than 20 %.

4.19 ASSEMBLY AND INSTALLATION OF THE BOILER
Boiler installation
Only a person with valid authorization for installation and assembly of the heat technology
devices can install the boiler. The installation requires an appropriate project that is in line with
the valid prescriptions and this instruction manual. Before installing the boiler must the
technician check, if the data given on the production label are in conformity with the data in the
project and the documentation attached to the boiler. The boiler must be connected in line with
the valid prescriptions, regulations and this instruction manual.
The producer takes no responsibility for damages caused by wrong connection or
operation.
Placing the boiler
The boiler is intended to be installed and operated in the premises with the basic environment
(AA5/AB5) following the STN 33 2000-3 norm. By the boiler installation it is necessary to keep the
safety distance of its surface from flammable materials according to their degree of flammability:
from materials of the flammability degree B, C1 and C2 200 mm
from materials of the flammability degree C3 400 mm
from materials of the flammability degree not approved by the STN 73 0853 400 mm
Examples of classification of the building materials by their degree of flammability:
degree of flammability A inflammable (bricks, blocks, ceramic tiles, mortar, parging)
degree of flammability B partly flammable (heraklith, lignos, board from basalt felt, novodur)
degree of flammability C1 difficult to ignite (hardwood (oak, beech), plywood, werzalit,
hardened paper)
degree of flammability C2 normal combustibility (softwood (pine, spruce), chipboard,
solodur)
degree of flammability C3 easily ignited (wood fibre boards, polyurethane, PVC, foam rubber,
polystyrene)
The sealing board or protection covering (on the protected item) must exceed the boiler edge
for at least 300 mm. Also other items from flammable materials must be protected in this way, if
they are placed near the boiler and it is not possible to keep the safe distance.
If the boiler stands on a flammable surface, it must be protected by an inflammable, heat
insulating mat, which exceeds the edge on the side of the feeding door and the ash tray door for
at least 100 mm. All materials of the A flammability degree can be used as an inflammable, heat
insulating mat.
The boiler must be placed in a such way ensuring sufficient space of at least 1 m from the front
and 0,5 m from the left (right) and rear side. It is necessary to leave the space of at least 1 m
above the boiler.
This space is necessary for basic operation, maintenance and eventual service of the boiler. It is
not allowed to place the boiler in dwelling premises (including corridors). There must be an
opening for the air inlet for burning of at least 200 cm2 depending on the boiler output.
CAUTION! The items from flammable materials must not be laid on the boiler and in the
distance shorter than the permitted (safe) one. The boiler must be turned off, if there is
a danger of fire or explosion due to the work (e.g. work with painting materials, glues, etc.).
Page 42
42
Air inlet
For correct operation of the boiler it is necessary to ensure sufficient air supply for burning.
There must be an opening for the air inlet for burning of at least 200 cm2 depending on the
boiler output.
Boiler connection to the heating system
Only a trained technician can install and service the ATTACK DPX boiler. Before installing the
boiler, it is necessary to flush (to clean) the whole heating system. The system can be filled only
the water treated to the values under the STN 07 7401: 1992. Callosity of the water must not
excess 1mmol/l and concentration of the Ca²Ѐ must be lower than 0,3 mmol/l.
If these conditions are not kept, the warranty is not valid!
Chimney
Connection of the appliance to the chimney hole must be always done with permission of the
appropriate chimney sweep association. The chimney must generate sufficient draught and take
the flue gas out into the atmosphere under the all operating conditions.
Correct dimensions of the chimney hole are important the correct boiler function, because the
burning, output and boiler life-time are influenced by the draught. The chimney draught directly
depends on its diameter, height and roughness of the internal wall. It is not allowed to connect
any other appliance to the chimney, where the boiler is connected. Diameter of the chimney
must not be smaller than the connection part on the boiler. The chimney draught must achieve
the prescribed values, but it cannot be too high, not to decrease the boiler output and interrupt
the burning (flame). If there is too strong draught, install the throttle flap into the chimney hole
between the boiler and the chimney.
Prescribed dimensions of the chimney section:
20×20 cm min. height 7 m
20 cm min. height 8 m
15×15 cm min. height 11 m
16 cm min. height 12 m
The exact chimney dimension is defined by the STN 73 42 10. The prescribed chimney draught is
given in the Technical parameters.
Flue gas connection
The flue connection must lead into the chimney hole. If it is not possible to connect the boiler to
the chimney hole directly, then the appropriate extension should be as short as possible, of up
to 1 m length, without any additional heating area and it should ascend in direction to the
chimney. The flue connection must be mechanically tight (it should be mounted to the boiler
and tightly fixed by screws) and tight against the flue leakage. The flue connections must to lead
through the foreign dwelling or commercial premises. The internal diameter of the flue
connection must not taper in direction to the chimney. It is not suitable to use the elbow
connectors.
Boiler connection to the electricity mains
The boiler is connected to the electricity mains of 230V/ 50Hzby an electrical cord with plug. In
the case of need, the power supply cord of the M type must be replaced with an adequate one
by the service organization.
The appliance must be placed in the way enabling to reach the connection plug. The boiler must
be connected to the 16A socket circuit by a circuit breaker (following the STN EN 60 335-1 +
A11:1997).
Page 43
43
Choice and connection of the control and regulation components
The boiler is delivered with the basic regulation and control equipment. Connection of these
items is given on the scheme of connection. We recommend extending the boiler regulation for
the next regulation components for more comfortable and economical operation. Each pump in
the system must be controlled by an individual thermostat not to let the temperature of the
heating water decrease under 65 °C.
The electrical installation related to the additional boiler equipment has to be done by
a specialist and following the valid regulations.
Connection of the next components is solved by a project architect according to the specific
conditions of the heating system. The electrical installation related to the additional boiler
equipment has to be done by a specialist and following the valid regulations.
Warning: the heating system must be equipped with a safety valve against
overpressure.
4.20 BOILER PROTECTION AGAINST CORROSION
Use of the mixing device (Regumat Attack – Oventrop) is a suitable
solution of the problem with corrosion. It enables creation of the
separate boiler and heating circuit. Thereby is the boiler protected
against undercooling below 65 °C and the creation of water
steams, acids and tars in the boiler´s feeding chamber is eliminated.
The Regumat Attack – Oventrop device keeps the constant
temperature of the return heating water flowing into the boiler
over 65 °C by setting the thermostatic head to the level 5–6.When
the individual thermal regulation mixing valve is used, it is possible
to control the temperature of the heating water independently on
the temperature of water in the boiler by setting the flap. The
temperature in the boiler has to be kept in the range of 80–90 °C.

4.23 BOILER CONNECTION
The boiler must be permanently operated by nominal output. If the boiler works at the output that is
lower than the nominal output, then for the case of the heat outtake it is necessary to connect it to
the accumulation tank with the volume of at least 460 l STN EN 303-5, article 4.2.5)
.
Connection with the accumulation tanks
Connection system is based on principle of heating up of water in accumulation tanks, where
the warmth is gradually taken away from the tanks according to the request from the heating
system. By the operation with several heating ups at full performance, accumulation tanks will
be heated for the temperature of 90–100 °C. Heating with accumulation tanks in connection
with the ATTACK DPX boiler brings more advantages. To the main advantages belongs longer
boiler life-time and also lower consumption of fuel.
Recommended volumes of accumulation tanks according to boiler output are following:
DPX15: 800–1 000 l
DPX25: 1 500–2 000 l
DPX35: 2 000–2 500 l
DPX45: 2 500–3 000 l
4.24 OPERATION WITH ACCUMULATION TANKS
When the boiler is heated up and working at the full output, it warms the water in the
accumulation tank to the average temperature of 80 °C, after 1–3 loadings. After the fuel burns
out, the heat is taken from the accumulation tank from the three-way valve. The time of outtake
depends on the size of the tank and on the external temperature. During the heating season it
can take 1–3 days (if the min. prescribed volume is kept). If it is not possible to use the
accumulation tank of the prescribed volume, then we recommend to use at least one tank with
the volume of 500 l to let the boiler run and to after run. The minimum volume of the
accumulation tanks is given in the table of technical parameters.

Advantages
The installation of the boiler with accumulation tank brings several advantages:
lower fuel consumption (even for 30 %). The boiler runs at full output until the fuel burns out
by keeping the optimum efficiency.
longer service life of the chimney and the boiler, minimum creation of acids and condensate
