ATTACK DP - Wood gasifying boiler

- Assembly, pre-heating and training of the attendance is perfomed by an assembly technician
trained by the manufacturer, who also fills in a document on the installation of the boiler.

-During wood gasifying, tar and condensates (acids) are created in the fuel bin. Therefore
behind the boiler the mixing appliance regumat must be installed to keep the minimum
temperature of return water of 65°C into the boiler.

- Operation temperature of water in the boiler must be of 80-90°C.

- The boiler must not be permanently operated with the output lower than 50%.

- When a circulation pump is used, it must be controlled by a separated thermostat in order to
keep the prescribed minimum temperature of return water.

- Ecological operation of the boiler is during nominal output.

- We recommend to install the boiler with storage reservoirs and Regumat which guarantees
economy in fuel in 20 to 30% and longer service life of the boiler as well as comfortable
attendance.

- If the boiler cannot be attached to the accumulation, we recommend to connect it at least with
one equalisation basin with the volume of about 25l for 1 kW of the boiler output.

- During the mode with decreased output (summer mode and water heating) it is necessary to
star t burning daily.

- Fuel must be used only dried of 12 - 20% moisture content (with a higher moisture content of
fuel the output of boiler decreases and its consumption increases)

- The choice of the right boiler size, that is its heating output, is a very important condition for
economic operation and right function of the boiler. The boiler must be chosen so that its
nominal output responds to heat loss of the heated object.

The guarantee does not apply for the boiler if:

- it is operated with wood exceeding 20% moisture content or with fuel not prescribed by
the manufacturer.

- if a proper mixing appliance Regumat is not installed in the system, which provides for
return water the temperature of 65°C.

- a functional thermostatic valve (WATTS STS20) is not installed on the cooling circuit of
boiler and connected to the source of cooling water.

This appliance is not suitable for using by those persons (including children), whose
physical, mental and sense- disability or the lack of skills obstucts the safe operation, if
they are not under restraint, or they were not trained by the responsible person for using
the appliance. It is necessary to look after the children to assure, that they will not play
with the appliance.

ATTACK PROFI

The ATTACK PROFI boiler version in comparison to the ATTACK STANDARD version
represents higher comfort of attendance, possibility of output regulation and possibility to
connect control and regulation elements.
Boiler temperature is kept at the level set at by user by means of control of the flue gas
ventilator´s rotations. Boiler regulator of the ATTACK PROFI boilers performs permanent
measuring of temperature of water in the boiler and indicates it on display. Regulator controls
rotations of the flue gas ventilator and the central heating (C.H.) pump adequately to this
temperature. To the boiler regulator, the flue gas thermostat is connected, that switches boiler
into the mode of the fuel shortage control, when the flue gas temperature decreases under the
set temperature. There is also an option to control the gear of the mixing 4-way valve.

Technical description and ways of regulation of the ATTACK PROFI boiler

Boiler temperature is kept at the level set at by user by means of control of the flue gas
ventilator´s rotations. Regulator measures temperature of water in boiler, indicates it on display
and controls suction fan and circuiting pump. Regulator is equipped with additional flue gas
thermostat and terminals to connect its sensor. Adequately to the situation, it is possible to use
thermostat to set the flue gas temperature for indication of fuel shortage and boiler stop, or for
setting of required temperature in the room. In dependence of the chosen usage, the sensor of
the flue gas temperature or the sensor of the room temperature should be connected into
terminals for connection of the flue gas thermostat and an adequate mode of regulation should
be chosen through parameter setting. From production is thermostat used for setting of flue gas
temperature. When it is set up for the first time, producer recommends to set value of the flue
gas thermostat in the range of 100-120°C. Temperature is set by button of the additional
thermostat in the temperature display mode. When the flue gas temperature decreases, the
boiler is switched into the mode of fuel shortage. Design of appliance also enables connection
of external contact thermostat into the terminals of the room temperature sensor.

Connection

Before you start appliance by the main switch, connect regulator, ventilator, circuiting pump
and connection cords into suitable sockets in the rear part of appliance. Sensor of boiler
temperature has to be placed into the boiler case.

WARNING! Before you connect regulator into the mains, check, if it is properly
grounded and if the terminal screws are fitted well.
ATTENTION! Max. total output of the appliances connected regulator must not exceed
450W.
ATTENTION! For extended function of regulator, it is possible to connect the UM-1
Module that enables control of additional boiler or C.H. pump. Connection of additional
appliances to module’s contacts have to be separated by appropriate relay.

The unused contacts of this module can stay unconnected.

Operation

After start of appliance, all points of display light for a while to check their correct function.
After reset, the regulator switches back to the last state before stop or power shortage.
Basic operation of appliance is controlled by setting of required boiler temperature set by
thermostat, all other functions are performed adequately to parameters programmed in the
service mode. In case that the boiler temperature setting is changed by the boiler temperature
button, the change is indicated on display for several seconds (e.g. [C 75] ) and this value
represents temperature that will the regulator struggling to achieve. This value can be checked
in the temperature display mode. In accordance to the type of installation and service settings
can be the button of additional thermostat used to set flue gas temperature or room temperature.
From production is this button intended to set the flue gas temperature. When the flue gas
temperature decreases under the set value, the regulator switches into the mode of fuel shortage
control and after the set time period - parameter [Fb30] - is the boiler stopped. This function
prevents from eventual discharging of accumulation tank after fuel burn-out in the boiler, when

- after expiration of time set by parameter [Fb30] - ensures boiler operation stop to avoid of
inverse heat flow from charged accumulation tank into cold boiler. Change of position of the
button of additional thermostat is for few seconds indicated on display, e.g. [100°].

Actual value of this setting can be also checked in the temperature display mode.
If the flue gas temperature is in the operation mode after burning-up lower than the value set by
the button of additional thermostat, then the suction fan and the circuiting pump are blocked,
which is signalized by flickering of additional thermostat´s control light. In this case it is
necessary to decrease the adjusted flue gas temperature value by the button of additional
thermostat, until the control light stops to flicker. Consequently it comes to restart of the
suction fan and circuiting pup operation.

When the fuel is being burned-down and the flue gas temperature decreases under the value set
by flue gas thermostat, the boiler is switched into the fuel shortage control mode and after
expiration of the set time – parameter [Fb30] – it comes to automatic boiler stop.

It is necessary to make setting of the boiler stop at flue burn-down adequately to flue gas
temperature, when the boiler is started-up and then to check it from time-to-time.

After pressing the START button, ventilator starts to work and the control process begins.
Ventilator is stopped by the STOP button.
If the regulator is not in the operation mode, temperature of water in the boiler is indicated on
display.
Example: [70°C] - STOP mode
[70°C] - Operation mode
[70°C] - Fire keeping in operation mode

Manual start of ventilator

During the boiler operation might the user need to turn the fan on manually (e.g. for suction of
gas from boiler before and during fuel load). After pressing and holding of START button for 3
seconds, the ventilator starts. Ventilator will work for period set in service mode or until the
STOP button is pressed.

Temperature display mode

To enter into the temperature display mode, press the OK button. Enter into this mode will be
indicated by quick flickering of the additional thermostat´s control light. Use buttons < and >
to browse in the information displayed to different temperatures. To exit the temperature
display mode, select [END] and press the OK button or wait for 1 min.

Required boiler temperature [C 80] - is temperature that the regulator tries to reach in the
operation mode. It is set by direct turning of button of the boiler thermostat and it is
indicated by short displaying.
Set temperature of the flue gas / room thermostat [100C] - this parameter indicates
temperature set by additional flue gas / room thermostat. In accordance to installation of
heating and setting of parameter FC (1 or 0) it represents the flue gas temperature (at lower
actual temperature, the regulator switches into the fuel shortage mode) or the room
temperature.
Actual flue gas temperature or room temperature [180°] - this parameter indicates actually
measured flue gas temperature or room temperature.

Setting of parameters – service menu

When the OK button is held for longer than 3 seconds, it is switched to the service mode,
where you can see and change programmed parameters. Service mode is indicated by
flickering of the additional thermostat´s control light. It is possible to browse parameters by
