Gasifying boiler Vigas
1. TECHNICAL DESCRIPTION
VIGAS thermal boilers are designed for the combustion of dry wood materials, using sawdust to wood logs
according to the dimensions of the gasification chamber, with a maximum diameter of 20 cm. Sawdust,
woodchips, splinters and cuttings must be burned in conjunction with wood logs. Thermal boiler VIGAS 29
UD is designed to burn brown coal. It is possible to use dry wooden material as a substitute fuel.
Boilers are welded from 4 – 6 mm steel sheets. Inner boiler sheets, which are in contact with boiler waste
gases, are 6 mm thick, others are made of 4 mm steel.
The heat exchanger is welded from steel pipes, 57x4,5 mm. Exterior boiler panels are made of 0,8 mm
sheet. Thermal insulation of the boiler is made of insulation material, NOBASIL 20 and 50 mm thickness.
Combustion gases pass through the steel boiler neck to the chimney.
The boiler space consists of a combustion chamber, where fuel is dried and gasified. Then accrued gases
pass through the fireproof concrete nozzle or a cast iron nozzle into the combustion chamber, where it
burns with the help of secondary air. Flue gases are intensively cooled in the exchanger. The boiler has
a light up damper controlled by a lever at the front of the boiler.
In order that the boiler complies with the requirements for non-demanding operations, it is equipped with an
AK4000 control located on the top panel of the boiler. The design of the system allows very effective
combustion of various kinds of fuel. The AK4000 Control with graphical display in basic configuration offers
the following:
controlled temperature of heated water ranging from 70 - 85°C (up to 90°C with accu. tank)
continuous and automatic control of the fan according to required output and type of fuel
connnection to and control of discharge fan
connection to and control of circulation pump
connection to the gases thermometer
connection to room thermostat (room temperature regulator is voltage free )
connection to extended regulation (Expander AK 4000) via BH BUS
connection to module AK 4000M data back-up, followed by PC evaluation
graphical schematic indicating hydraulic boiler connection as requested
real time set
Configuration VIGAS
Lambda Control
offers :
control of the servo flap of primary and secondary air, based on data received from the lambda
sensor oxygen level reading.
during a power cut, AA batteries will close the servo-operated flap and this prevents draught from
the chimney burning up the fuel.
The boilers are equipped with a STB thermal fuse, which disconnects the boiler fan if overheating occurs
(above 100°C). A safety mechanism to prevent the boiler from overheating is a requirement of the STN EN
303-5: 2012 standard. It is recommended to install a safety valve TS 131 ¾“ in the exchanger to avoid
overheating.

4. BASIC CONFIGURATION OF VIGAS BOILER WITHOUT
EXHAUST FAN
The advantage of the exhaust gas thermometer is to control the maximum exhaust gas temperature, and when this is
reached by the boiler, a fan will come into operation to lower the engine RPM. This results in higher boiler efficiency
and lower fuel consumption. If installed with an accumulator tank, the thermometer will shut down the boiler when fuel
is burned down. The water temperature inside the boiler and accumulator tank has no influence on boiler shut down.
4.1 VIGAS BOILER CONTROL
4.1.1 Boiler activation
4.1.2 Boiler active – heating phase, heating regime „On“
4.1.3 Boiler active – burning phase „74°C“

In the heating phase, the boiler gas exhaust temperature is lower then
the
minimum set-up exhaust gas temperature
. Minimum and maximum
temperatures can be modified in boiler set-
up parameters. Minimum
standard exhaust gas set-up temperature is up 90°C and maximum set
-
up temperature is 220°C.
Boiler can be in heating mode for up to 60
minutes with minimum of 2min. If boiler does not reach bu
rning phase in
this time, it will automatically shut down – sign „END“.
OFF will be displayed when the boiler is switched off. To START the
boiler press middle button ENTER.
The burning phase is active, when the exhaust gas temperature is
(
end) +10 °C or after reaching desired temp. Burning phase is
controlled by PID regulator on the basis of chimney and boiler temp.
If the
temperature rises 1°C above desired temp., the output will be 0
%. If it
decreases >2°C below desired temp., the output will start again.

ying servo at 45%, secondary air is closed. When
displaying 0% primary air is also closed. The flap will move to position
0% only when boiler is in the „OFF“ or „END“ phase.
In the heating phase boiler gas exhaust temperature is lower then setup minimum
exhaust gas temperature. Minimum and maximum
temperatures can be modified in boiler set-
up parameters. Minimum
standard exhaust gas temperature set-up is up to 50°C
and maximum
set-up temperature is 220°C. The pump operates in a continuous
wave during o
pen burn, depending on the boiler water temperature.
The burning phase is active, when the exhaust gas temperature is
(
end) +10 °C or after reaching desired temp. Burning phase is
controlled by PID regulator on the basis of chimney and boiler temp. If
the
temperature rises 1°C above desired temp., the output will be 0
%. If it
decreases >2°C below desired temp., the output will start again.
The graphic control is used for this operation.

Fuel inside the boiler moves spontaneously towards the fireproof nozzle. Ash falls through the nozzle and
is deposited in the combustion chamber. Boiler output is regulated automatically according to the set-up
temperature of outlet water. If there is a mains power cut over a long period of time or if the automatic
control fails, it is possible to heat as follows (only applicable for central heating systems with gravitation
flow): open chimney flap and open bottom door a little. If this way of heating is used, it is necessary to
check outlet temperature more frequently and to add less fuel. The boiler may easily become overheated,
if the chamber is full.

During optimal wood burning and keeping minimum temperature of the reverse water at 60°C will ensure
that the gasifying chamber and exchanger will only slightly soot. Using damp wood may ca
use steam to
condense on the walls of the combustion chamber, which creates tar on the surface.
ATTENTION
!!!
Use only recommended fuel.
It is advise not to overload the boiler with fuel when in temporary period, boiler tar can be
decresed.
When adding fuel, do not load between the flange and the chimney flap, which can cause inaccurate
flap closure.
It is important to lay fuel properly, so it will not stop the upper door from closing. Forcing the door
closed may damage the door‘s concrete innerwall.
It is recommended that only people over 18 years of age should operate the boiler.
Exchanger cleaning
It is necessary to clean exchanger pipes once a month using the fire rake (round plate).
Recommendation:
If the exchanger is not cleaned regularly it will become clogged with tar. Do not use a
solvent. The boiler must be cleaned
whilst it is hot! Heat boiler to approx 80°C (without fan) through open
upper door and chimney flap. Then close the flap and door. Using gloves, carefully open exchanger
cover. Clean clogged pipes with relevant accessories. After cleaning, close excha
nger cover and let the
boiler burn / gasify for approx. 5 hours at maximum performance, in order to get rid of any remaining tar.
Warning: During cleaning the boiler room must be well ventilated!
Combustion chamber cleaning
It is recommended to sweep out ash and dust that has fallen
and settled in the combustion chamber once every 3-5 days.

water pressure, door seals, chimney flap tightness, exchanger cover and seal, flue cleanliness
and fan
performance.
WARNING :
Before boiler is shut-down for the
summer season, clean combustion chamber thoroughly, do not leave
any condensed moisture inside and open bottom door and chimney flap.
The boiler door is stabilized in 3 ways –
two rotary pins and a door catch. If the
door does not fit tightly, it i
s also possible to fix it from the hinge side. Slightly
turn hinge to release and turn by hinge screw and then move door in desired
direction. To change gasket 1 points out the place, where gasket is joined.
The heatproof nozzle is a block made of heat-
proof concrete and its use is to to
mix gases with secondary air to ensure efficient burning.
The nozzle is located
on the water cooling rack. The nozzle is surrounded with heat-
proof concrete at
the same height as the nozzle. The life of the nozzle is dependent on
mechanical damage as a
result of fuel loading or stoking the fire. Therefore, the
nozzle is considered as a spare part. Cracks noticed on the nozzle are not a
reason to change the nozzle. It is only necessary to change the nozzle if it is
dropped or is broken. Remove the pieces of the broken nozzle and replace with
a new nozzle ensuring that it is inserted and fits into the opening.
When cleaning exchanger pipes (pic.3/24) make sure that the flap area is clean, as well as the flap itself.
(pic.3/16). Leakage can decrease boiler performance.

Secondary airway cleaning
Attention!!!
During cleaning disconnect the boiler from the power supply!
Step 1: Unplug fan and flap servo-unit connectors
Step 2: Under the fan plate romoval (see chap 15.4 for assembly)
Step 3: Vacuum out the secondary air pipes and check if it is clean.
Cleaning the boiler’s pipe airway system is necessary to achieve optimum burning. If sawdust is used as
a
fuel often, the airway must be cleaned at least once in the season. The system is built with primary and
secondary air trunks. The boiler co
nstruction disassembly of parts to enable areas to be cleaned. When
the fan cover is removed (8) pic.3 this allows ccess to the fan. To clean the pipe airway system
take the
following steps:

The position o
f the secondary air flaps can considerably affect burning
quality. VIGAS
Lambda Control
boilers control the amount of secondary air
automatically. This option provides optimum conditions for burning of
all wood types. In VIGAS boilers without lambda sensor the
mixture
of primary and secondary air can be adjusted by screws „1“.
Optimum adjustment of secondary air screws „1“ is 2,5 turns
from
factory set. To change or control position follow these steps:
Step 1: loosen the safety bolt nut on screw „1“,
Step 2: drive screw „1“ in towards boiler all the way
Step 3: then, adjust by 2,5 turn (optimum),
Step 4: tighten safety bolt nut.
Boilers without lambda sensor are equipped with a safety flap (above
the fan) „2“ which stops air going through the fa
nin to the boiler when
the fan is stoppped (only chimney draught).
In case the boiler does
not have sufficient output, check the function of this.

16.1 SAFETY DRAIN VALVE
Cooling safety exchanger use:
Primary airway cleaning
Check primary airway pipes and only clean if necessary. Congestion can occur
when using wet wood or
boiler runs for a long time in low performance.
Type of
primary airway design is different for each boiler model.
Step 4: Dismantle primary air separation panel.
Step 5: Use vacuum and scraper to clean primary leads and check if clean.
Step 6: It is possible to dismantle the vertical primary air lead but only if it is
absolutely necessary. With boilers VIGAS 16, VIGAS 25 a VIGAS 40
side primary air tube, also ( step 6/a, step 6/b).
Note: It is necesary to use silicone heatproof seal, when this action is
repeated.
Step 6./b
Vertical
primary air lead
A cooling safety exchanger with drain valve TS 131
provides boiler protection against overheating during a
power cut. By forced circulation the pump and water flow in
the central heating will shut down. If there is not an option
to have an auto
matic gravity convection or minimum heat
consumption of 5 kW, the boiler may overheat. The drain
valve TS 131 and cooling exchanger will stop the boiler
from overheating.
Assembly of drain valve TS 131:
Screw the drain valve TS 131 into the boiler sock
et „1“ so it
is water tight. The safety exchanger must be water tight.
The second connection „3“ pic., must be connected
to drain
via a tundish. Insert the thermal sensor into ½“ socket, pic.
„2“.
Warning
:
The assembly of the valve and thermal sensor
is
necessary before the
central heating system is filled with
water.
The pressure of cooling water can not be lower than the
pressure of the mains water.
It is advised not to loosen the ¾“ socke
t „2“ pic. This can
cause water leakage. There is an aluminium ring „4“
under the insert „3“ to seal the copper pipe „5“. If there is
a water leak, tighten ¾“ insert „2“.
Operation rule:
The drain valve is regulated by hot water. If the water temperature is 95°C the valve opens.
Water running
from main source
will absorb the temperature from the boiler and prevent it from possible damage and
overheating. This boiler protection system complies with standards STN EN 303-5:2012.

The electronic control allows the connection of the pump to the power board unit of the
AK4000S without using an expander, even in basic version. The operation of the pump
depends on the selected hydraulic scheme and boi
ler temperature. The pump operates in
a pulsating cycle or persistent cycle.
Pulsating cycle
allows the pump to go „ON“ or „OFF“ at specific times. The activity ratio
depends on the boiler output temperature. The advantage of this cycle is to protect the
boiler against low-temperature corrosion. Pump activity is indicated by blicking pump icon.
Persistant cycle is used only with a 3-
way thermostatic valve or Ladomat installation. See
chap. 13.4.1.
When the pump is in operation, the symbol will be flashing on the display.
The discharge fan „2“ is
designed to eliminate exhaust gas in the boiler area during
fuel refilling. In case the boiler‘s chimney does not comply with minimum
parametres
„A“ and „B“, it is recomended to install a discharge fan. This should be
installed between the chimney flue and the chimney body.
The condenser „3“
should be attached on the side of the boiler. It is connected to the power board unit
It is possible to order the AK 4000S in two different sizes.
V25 (order no. 0507)
– for VIGAS 16,18DPA, 25, 29 UD.
V80 (order no.
0508) – for VIGAS 40, 60, 80, 100.
By connecting the indoor thermostat to the boiler, maintenance will become easier. It is
necessary to connect the indoor thermostat to the AK4000S power board. Connect to T3
input contact. The switching contact element is voltage free.
If contact T3 is disconnected,
the indoor thermostat „OFF“ sign will be displayed. The blower fan will shut-
down. The
boiler status is indicated by „ “ symbol
. When the indoor thermostat is „ON“ again, the
boiler is activated.
As standard in the boil
ers VIGAS, one load is sufficient for 12 hours of operation which
means that it uses less than 30% of rated output. In view of the life of the boiler it is
preferred that the boiler operates at least at 50% of rated output. If the boiler VIGAS is used
with
ACCU
tank, 100% of rated output is used to achieve the desired boiler temperature. If
there is current requirement for heating, 100% output of the boiler is divided into charging
ACCU tank and heating. In this case, the tank is recharged by the excess out
put of the
boiler. In view of the fact that the boiler and ACCU tank
is hydraulically connected to each
other, the temperature of the ACCU tank
and the boiler rises to the desired temperature of
the boiler together. After exceeding this temperature by 10°C,
boiler goes into the
attenuaton (0% boiler output). In this mode, heating and charging ACCU tank is
managed solely by means of pumps. The great advantage of this system control is that in
the attenuation mode, it is possible at any time to add the f
uel to the boiler, without
overheating of the ACCU tank
, which in practice increases the time between fuel loading.
The automatic re-heating up takes place only after the exhaustion of ACCU tank
at the
selected temperature MinT. ACCU tank minimal temperature
volume can be adjusted
from 20°C to 70°C. After burning out of fuel and decrease of chimne
y temperature to the
boiler set end, the boiler will shut down. In
a combined automatic boiler VIGAS 18 DPA,
after burning out of fuel "wood" boiler will automatically switch to fuel "pellets" and continue
heating another few days.
NOTE: For all hydraulic circuits with ACCU tank, there must be a thermometer for ACCU
tank (code 3032) connected to regulation AK4000 and its location to insert at the top of the
accu. tank.
