ATTACK DPX - Wood gasifying boiler

- Assembly, control heat up and attendance training is perfomed by field engineer trained by

producer, who also fills in the protocol about boiler installation.

- At wood gasification, it comes to formation of tar and condensates (acids) in the fuel chamber.

Therefore the mixing device has to be installed with the boiler to keep minimum temperature of the

return water into boiler at 65°C.

Operation temperature of the water has to be in the range of 80-90°C.

- The boiler cannot permanently operate in the outout range lower than 50%.

- When using the circuiting pump, its operation has to be controled by detached thermostat to

ensure prescribed minimum temperature of return water.

- Boiler operation is ecological at nominal output.

- Therefore we recommend to install boiler with accumulation tanks and mixing device, which

ensures fuel saving of 20-30% and longer boiler and chimney life-time, together with more

comfortable attendance.

- If you cannot connect the boiler into accumulation, we recommend connect the boiler at least with

one equalisation basin with approximate volume of 25l per 1kW of the boiler´s output.

- Daily heating-up is necessary, when the boiler operates at lower output (summer operation and

D.H.W. heating).

- Use only dry fuel with humidity of 12-20% (output decreases with increasing humidity and fuel

consumption is increased).

- Correct boiler choice, i.e. its heating output is very important condition for economical operation

and correct boiler function. The boiler has to be chosen by nominal output adequate to temperature

losses of heated object.

- Boiler can be used only for purpose that it is intended to and only in the way described in

this manual.

- WARNING – After disconnection of operating boiler from electricity mains, the

burning continues further in attenuation regime. Do not open boiler door, until the

boiler temperature decreases under 40°C.

Guarantee for boiler is not valid if:

-it is not operated with prescribed fuel -not with wood of humidity lower than 20% or if it is used

with the fuel that is not prescribed by producer

- the mixing device Regumat ATTACK-OVENTROP is not installed in the system to ensure

temperature of return water into boiler at least at 65°C

- functional thermostatic valve is not installed in the aftercooling circuit of the boiler (WATTS

STS20), connected to the cold water source.

This device is not intended for usage by persons (including children) that are physically, sensually,

mentally or due to unsufficient experiences and knowledge unable to use it safely without being

under control or being instructed to use by person responsible for their safety. It is necessary not to

allow children to play with the boiler.

If the electrical cord is broken, it has to be replaced with special cord, available from

producer or service technician!

Be carefull while using the device! The Lambda probe works at high temperatures (300°C)

and by uncareful manipulation there is a danger of scorch!

Warning sign

This warning sign always appears in the instruction manual, when it is necessary to warn about

possible bodily injury and material damages, if this manual is not kept properly.

Two types of warning signs are used in this manual:

WARNING Warns about life-dangerous situations and situations that may cause bodily

injury and damages, in case that necessary actions were not kept.

ATTENTION warns about less safe work methods and processes that may cause bodily

injury or material damages.

ATTACK DPX STANDARD

The wood gasifying boiler "ATTACK DPX Standard" is controled by boiler and flue gas

thermostat.

1 – Emergency

thermostat with reset

2 - Fuse

3 - Main switch

4 - Flue gas thermostat

5 - Boiler thermostat

6 –Thermomanometer

Description:

1. Emergency thermostat with reset - boiler protection against overheating (after reaching

temperature higher than 110°C it comes to boiler disconnection from electricity mains) after

decrease of water temperature under 85°C it is necessary to push the restart button manually

after removing cover of reset .

2. Fuse - boiler protection against short circuit

3. Main switch - boiler start and complete boiler stop for the case of need.

4. Flue gas thermostat - at decrease of flue gas temperature under adjusted value is the fan

switched off

ATTENTION! While heating-up, set this thermostat to 0°C. After fuel burn-out set the flue

gas thermostat to „Operation“. When the temperature decreases under adjusted value, the

suction fan is switched off. If you wish to turn the fan on again, set the lower temperature on

the flue gas thermostat. It is necessary to test the optimum setting for operation.

5. Boiler thermostat - serves for setting of max. temperature of water in boiler (after exceeding

of adjusted value is the fan switched off and boiler works at minimum output, after decrease of

given temperature is the fan switched on again and boiler works at maximum output).

6. Thermomanometer - indicates outlet water temperature from the boiler and operation pressure.

Pull rod of the chimney flap - serves to open and close the heat-up flap (everytime the feeding door

is opened).

Lever for exchanger cleaning - serves for cleaning of exchanger´s tubes

ATTACK DPX PROFI

The ATTACK DPX Profi version in comparison with Standard version represents higher attendance

comfort, possibility of output modulation and possibility of connection of control and regulation

elements.

The boiler temperature is kept at the level set by the user, by setting up number of rotations of the

flue gas fan. The ATTACK PROFI boiler regulator measures the temperature of water in the boiler

continuously and indicates its value on the display, controlling pump of central heating at the same

time. There is a possibility to connect a room thermostat to boiler regulator. The room thermostat

ensures regulation of temperature of heated rooms. Control of gear of the four-way mixing valve is

possible as well.

Control light 1:Lights, when the boiler was switched on by „+“(5), expires automatically after

burning out (fuel is gone and boiler is switched off). Expires also in case, when the

boiler was switched off manually by „-“ button (6).

Control light 2: Lights, when following errors occure:

oincorrectly measured values of the flue gas temperature

osee chapter Errors and warnings

Control light 3: Lights or flickers, when error or warning occurs:

oSTB on - Reset (error, message (3)lights)

oincorrectly measured values of boiler temperature(error, message (3)lights)

oToo high temperature of flue gas (warning, message (3)flickers)

oOverheating – do not open! (Boiler temperature over 90°C, warning flickers

display 3)

osee chapter Errors and warnings

Display 4: Diplays operation data for different settings at errors. In case that the boiler is switched

off and no error is displayed, illumination of display expires after 15 minutes.

Button 5 (+): After first key depression, the dipslay illumination is on. Boiler is switsched on after

repeated depression of the key - heating up or loading is possible afterwards. Also

another settings given in the menu can be done via this button (see below - button 7).

Button 6 (-): Serves to switch the boiler off. This function is used only for emergency shut down,

e.g. if there is no water in the heating system or if the sensor for overheating is not

working. . Also another settings given in the menu can be done via this button (see

below - button 7).

Button 7 (←): After first key depression, the dipslay illumination is on. Enter the „Selection“

menu via repeated depression of the key. Afterwards, by „+“ (5) or „–“(6) button it is

possible to get several information and to perform different settings.

! Buttons 5 and 6 have different functions.

Button 8: Reset of the emergency thermostat button (STB)

If the STB was switched on because of too high boiler temperature (≥95˚C) and the

boiler temperature decreased to 85°C, it is possible to reset the STB by removing cover

(8) and pressing the key underneath (8). Error is removed automatically. If fault occures

again, it is necessary to inform technician.

Reasons:low warmth offtake, power failure, circuiting pump - faulty mixing valve. To

decrease temperature to 85°C, regulators switches connecting pump on.

If the flue gas fan is not working, the boiler door must not be opened!
