1. TECHNICAL DESCRIPTION
Combined warm water boiler VIGAS 18DPA and VIGAS 26 DPA offers two different systems of fuel
combustion. Wood fuel combustion provides effective way applied with all Vigas boilers. Pellet fuel heating
is provided by classic burning process on fire grate, made of heat resistant steel, where pellets are
delivered by screw feeder. Boiler VIGAS 18 DPA and VIGAS 26 DPA is designed to burn pellets with
diameter of 6 mm and lenght up to 40mm, as well as dry wood materials from sawdust to wood logs of 52
cm long, with max. diameter 20 cm. Sawdust, woodchips and cuttings are recommended to burn together
with wood logs.
Boilers are welded from 4 and 6 mm steel sheets. Inner boiler sheets, which are in contact with boiler
gases are 6 mm thick, others are made of 4 mm steel. The heat exchanger is welded from 57 x 4,5 mm
steel pipes. External casing of is made of 0,8 mm steel sheets. Heat insulation of the boiler is formed by
20-50 mm mineral wool. The combustion gas is discharged through steel flue gas into the chimney.The
pellet container is designed from 1,5 mm steel sheet and its volume is 250 l.The integral components of the
boiler include: front gear unit, electric ignition unit, security tourniquet, air distributor with servo and fan,
chimney temperature sensor, ultrasound sensor to detect level of pellets. Internal space consists of
combustion chamber, where fuel is dried and combusted. Produced wood gas is carried through nozzle
into combustion chamber, where it burns with support od secondary air.
Pellets are led directly to combustion chamber by accurate dosing from container during combustion with
assistance or regulated air supply. Furthermore, the flue gases are led to double-row heat exchanger,
where intensively cooling down untill reaching the flue gas. Unburned ashes and waste is seated in the
combustion chamber, which is advised to be clean approximately once a week. Boiler offers simple
maintenance due to AK4000 control, located on the top of the boiler.
Control AK4000 offers and permits following actions:
to control heating temperature reached by changing of fan speed using by PID regulator
to control and manage operation of pellet feeeding device
to read water boiler temperature
to read volume of pellets in the container
to read temperature of flue gases
to read motor temperature of pellet feeding device
to connect and control the discharge fan
to connect and control circulation pump
to connect and control room thermostat
to connect extended regulation (Expander AK 4000) via BH BUS
to connect modul AK 4000M for data back-up and possible evaluation via PC
option for graphic view of hydraulic schemas with connection per requirements
SAFETY FEATURES
Boiler is supplied with STB safety, which disconnects the boiler fan to avoid boiler overheating above
100 °C and it is equipped with safety cooling exchanger according to EN 303/5: 2012. Manufacturer
recommends to purchase Honeywell TS131 3/4“ safety valve - to be assembled to the safety cooling
exchanger. The boiler is equipped with a safety cell feeder (tourniquett) driven by chain transmission to
avoid pellet re-ignition inside container. In case of power failure or device error, there is always security air
gap between the container and pellet combustion chamber which prevents ignition of the pellets in the
container. To avoid engine gear damage by possible feeding screw blockage or tourniquet blockage, the
boiler is equipped with a safety thermometer that detects the temperature of the engine and if temperature
is 80 °C, engine will shut down.

Boiler VIGAS 18 DPA offeres possibility, that during fuel change from pellets to wood or wood to pellets, it is
not necessary to perform any technical modif
ications on the boiler body. It is only required to choose type of
fuel on the display of AK 4000 control. After selecting the fuel type, servomotor driven shutter will
automatically move to desired position (pic.3/6). Boiler design and air control enables
fuel from „WOOD“ to „PELLETS“, after „WOOD“ fuel has burned out.

Symbol „OFF“ will appear, as shown on the picture, if boiler is switched
off, by pressing middle button „ENTER“, round button pictogram
Ignition mode shows symbol „ON“.
It is automatic process supported by
chimney temperature monitoring.
Discription of ignition:
1. Pump on, monitoring of current chimney gas temperature.
2. Ignition coil on ,fan will blow onto grate.
3. Screw feeder on .
4. Finishing ignition mode and switch to burning mode will start,
current gas temperature exceeds sensored gas temperature over 2 °C
The boiler will switch off, if this condition is not realized, indicated by
symbol „END“ and pellets ignition error.
Ingniton pellets error:
- Clean the burner (pic.3/24) too much ash on the burner,
- Check pellet volume in the container,
- Check igniton coil function (pic.3/35).

mode, the boiler is controlled by a "PID controller based on the
temperature of the boiler and flue temperatures. If the boiler temperature
exceeds the desired temperature by 1°C, output is 0% if the temperature
drops below 3°C desired temperature, the boiler is re-ignited. Current
output is displayed in percentage as a symbol. "20%".
Inside boiler container is p

empty), this condition is
Simultaneously, information line shows
remaining time period for boiler to shutdown. This condition is displayed
by empty container symbol “ “ and sign „END“.
Pressing „ENTER“ display offers round button. Pressing button ⊳ boiler will shut down. After

In case of installation and selection of discharge fan
(see chap.10.1.3), there is possibility using it to
increase chimney effectivity by permanent running.
Possibility to adjust speed from 30% up to 100% or
completely shutdown to „OFF“.
Correction of output can be used to increase or
decrease the time of dosing pellets in the same
period. The value can be set in the range of -3 to +3.
One step correction = change of time of dosing in one
period of 0.5 seconds. Correction can be used to
achieve optimum combustion of pellets, or
modification of the boiler output. When the quality of
the pellets is according to EN Plus A1, it is
recommended to set the correction to "0". This setting
will take effect for displaying the maximum output of
the boiler.
When you select "AUTO" will occur after burning out
of fuel "wood" and flue gas temperature reaches
end (see Sec. 5.3.2) to automatically transition to
fuel "pellets" and the subsequent continuation of
burning. In "Auto" mode is recommended temperature
shut- end 50°C. When connecting the ACCU tank,
the minimum temperature shutdown automatically
moves to the required temperature of the boiler.
If elected, "OFF" will occur after the end temperature
for the boiler and the statement "END".
