3. Boiler description
3.1 Boiler drum construction
The cast iron section boiler drum is the main part of boiler and it is manufactured of grey cast iron according
to EN 1561
• central sections – quality 150 (previously ČSN 42 2415)
• front and rear sections – quality 200 (previously ČSN 42 2420)
The pressure parts of boiler conform to the strength requirements according to EN 303-5.
The boiler drum is assembled of sections by means of pressed on boiler insertions and secured by means of
anchor bolts. The sections create the combustion and ash-pan space, the water space and convection part.
The inlet and outlet of heating water are situated in the rear part of boiler.
The rear section of boiler in its upper part has a smoke extension piece and heating water flange, in the lower
part there is the return water flange with a sleeve piece for inlet and outlet cocks. The cleaning door and ash
door with mounted burner are affixed to the front boiler section.
The whole boiler drum is insulated by means of a health harmless mineral insulation which reduces the
losses caused by the heat transfer into ambient. The steel shell colour is treated by means of high-quality
komaxit spray.
3.2 Control, regulation and safety elements
Elements for control, regulation and safety placed in the control cabinet
Thermomanometer serves for measuring the temperature and pressure of water in the heating system and
is located in the upper part of the boiler shell. The check valve for pressure gauge connection is located in the
upper part of the rear boiler section.
Operating thermostat switches off / switches on the operation of the burner according to the set
temperature of heating water.
Signalling of safety thermostat signals the activation of the safety thermostat (overheating of the heating
system above 97 °C)
The safety thermostat is placed in the control box and serves for ensuring the heating system against
overheating. This thermostat is set by the manufacturer to a temperature of 95°C, i.e. to a higher temperature
than can be set as the desired temperature on the boiler. When you turn off the safety thermostat unblocking
must be done manually. The safety thermostat can be turned on only after the temperature has dropped
below the set value. We have to unscrew the black cap of the safety thermostat and by using a suitable
object we press the button.
In case of repeated switching of the thermostat the boiler must be shut down and the reason of repeated
overheating of the boiler must be found out.
The thermostat of the pump switches on and switches off the pump of heating water according to the set
temperature.

The air rosette of cleaning door and the lower stifling element is not used at the boiler with an automatic
combustion of wooden pellets and must be permanently closed.

Elements for control, regulation and safety placed on the burner
• Control Module of boiler (version VIADRUS HERCULES Green Eco Therm XJ) or automatic (version
VIADRUS HERCULES Green Eco Therm XS).
• LCD display with control buttons, that is designed for change of the values of operating parameters
(version VIADRUS HERCULES Green Eco Therm XJ).
• Potentiometer – for setting the boiler output (version VIADRUS HERCULES Green Eco Therm XS).
• Photo sensor, which monitors the intensity of the combustion process.
• Transport hose with reinforcing spiral, which melts in the case of penetration of fuel back through the
knee of burner, thus preventing further supply of pellets into the burner.
• Sensor of penetration of fuel (TD) is placed on the knee of burner and is activated in case of the
surface temperature above 90 °C. Burner and fuel feeder are stopped in case of activation of this sensor
and the system is switched over into reporting of a failure. The failure mode is deactivated by switching
off and on of the main switch. It is necessary to determine the cause of the failure and take appropriate
measures, namely before restarting of the burner;
• Reversible thermal label displays the operating temperature of the burner body. This temperature is an
indicator for operating mode of the burner and temperature of flue gases which pass the combustion
chamber back into the fuel tank. The initial state is shown in black colour for all thermally active parts. If
the temperature is increased, the segments gradually are getting a light colour, according to the
temperature range of individual heat-active segments. The reversible thermal label should be checked
as needed. Increased temperature in this section signals the necessity to clean the boiler, grate of
burner or routes of flue gasses and smoke flue. During cooling of the main burner body the colour of the
label returns to its original state (all segments are black).
• Irreversible thermal label displays overheating of the knee of burner. This label in case exceeding of
temperature of the burner knee irreversibly changes its colour.
The initial status, the active segment is white, the temperature hasn’t
reached the degree of activation 104 °C;
The status at activation, the active segment is dark, the temperature
has exceeded the degree for activation 104 °C; activation of 104 °C;

CAUTION:
•Activation of irreversible thermal label is signalling overheating of the knee of burner. Status of this
label is irreversible and in case of damage it has to be replaced. Control and service of burner may be
performed only by an authorized technician.
•This thermal label is activated for example when hot combustion products pass back via the fuel feeder
due to an increased resistance of the smoke flue or a lower draft in the chimney. In such cases the
transport hose that connects the fuel feeder and burner body can be damaged and will be necessary its
replacement.
•In case of these emergency statuses the warranty for the burner is void.

forth of flame into the fuel feeder;
• Socket for connecting the fuel feeder, which ensures power supply into the motor of the fuel feeder;
• Reversible thermal label from a liquid crystal with the indicator of current temperature of the
body of burner.
• Irreversible thermal label from a liquid crystal which signals the high temperature of the knee of
burner, preliminarily sets the conditions for the non-warranty service of the main module of burner and of
any kind of damage to the hose for fuel supply;
• Fuel feeder with an inlet cable and 1 ~ plug.
• Transport hose with reinforcing spiral, which is made partly of a transparent heat-resistant material

5.3.4 Mounting of the fuel reservoir
ATTENTION!
In the event that it is installed the supplied wooden fuel reservoir, it is necessary to place a fireproof
bulkhead between it and the boiler.
• According to Fig no. 15 you must screw the flange of fuel feeder (3) to the lateral part of the fuel
reservoir (6) by using 6 pcs screw M8 x 20 (5), M8 nuts (2) and washers 8.4 (4);
• Then you must screw together inclined bottom (7) by means of 4 pcs screw M8 x 30 (8), M8 nuts (2) and
washers 8.4 (4);
• Put the assembled inclined bottom (7) into the fuel tank;
• Insert the fuel feeder (1) into the flange of fuel feeder (3).
• The fuel feeder should form an angle of 45 degrees with the horizontal floor in order to ensure optimal
operating conditions. The lower part of the feeder should be placed at the lowest point of fuel reservoir.
The fuel feeder and reservoir must be placed so that there is ensured a safe operation of equipment and
an easy access and maintenance.
ATTENTION: Any change in the angle of the fuel feeder affects the amount of the dosed fuel:
• reduction of the angle will lead to an increased dosing of fuel;
• Increase of the angle will lead to a reduced dosing of fuel;
• Then position the fuel tank with the fuel feeder in the proximity of the burner so as to prevent clogging of
the transport hose with the pellets during supply of fuel and also to make it possible to open the cleaning
door and ash door.
• After mounting of the shells (see chap. 5.3.5) interconnect the transport hose with the knee of burner
and secure by means of hose clamps. ps.
