Description
3.1
Boiler structure
The main part of the boiler is the sectional boiler drum made from grey cast iron according to EN 1561:
•
Central sections
– grade 150 (earlier ČSN 42 2415)
•
Front and rear sections – grade 200 (earlier ČSN 42 2420)
Pressurized parts of the boiler complies with requirements for stiffness according to EN 303-5.
The boiler drum is assembled from sections by means of pressed boiler insertions and is fixed by anchor bolts. The
sections create the heating and ash space, the water space and the convection part. The heating water input and
output are situated in the rear part of the boiler.
The rear section of the boiler has in its upper part a chimney pot and a heating water flange, in its bottom part has a
return water flange with a mouthpiece for a filling and draining cock. The cleaning and ash doors with an inbuilt
burner are fixed to the front section.
The whole boiler drum is isolated by healthy mineral insulation, which decreases losses caused by heat
transmission to the surroundings. The steel cladding is painted by quality comaxite paint coat.
A pellet burner of PellasX is mounted in the ash door. In the version VIADRUS A0C-S20P it is a burner PellasX
Hybrid mini, and in the version VIADRUS A0C-S28P it is a burner PellasX Hybrid 35. These burners are equipped
with a fan.
On the right (on the left) from the boiler it is placed a steel-sheet pellet reservoir with a capacity of 300 l. The
reservoir is connected with the burner by means of a feeder and a connecting hose.
An electric cabinet, in which the control unit and a display are situated, is mounted on the upper part of the cladding.

Possibility of placement
During boiler mounting and operation it is necessary to observe all requirements of ČSN 06 1008.
It is prohibited to place the boiler in a residential premise (including corridors)!
Placement of the boiler in the view of fire regulations:
1. Placement on the floor from inflammable material
− Install the boiler on an inflammable, heat-insulated basement exceeding the ground-plan of the boiler with the
reservoir on sides by 20 mm.
− If the boiler is placed in a cellar, we recommend to install it on a supporting brickwork with the high at least 50
mm. The boiler has to stay horizontally, possible unlevelnesses of the supporting brickwork are to be
eliminated by means of a regulating screw of the motor seat.
2. Safety distance from flammable materials
− During installation and at operation of the boiler it is necessary to observe a safety distance 200 mm from
flammable materials with the combustibility grade A1, A2, B and C (D);
− For lightly combustible materials with the combustibility grade E (F), which quickly burn and burn themselves
even after removal of the ignition source (for example, paper, paste-board, cardboard, asphalt- and tarboard,
wood and fiberboards, plastics, floor cloths) the safety distance is doubled, it means to 400 mm;
− The safety distance is to be also doubled in case when the grade of reaction to fire is not proven.

Checking activities before actuation
Before actuation the boiler into operation it is necessary to check:
a) Filling of the heating system by water
Water for filling the boiler and the heating system has to be pure and colorless, without suspended matters, oil
and chemically aggressive materials. Its hardness has to comply with ČSN 07 7401, and in case that water
hardness doesn’t comply, it is necessary to provide its proper preparation. Neither multiple heating of water
with higher hardness prevents from exclusion of salts on the heat-exchanger walls. Flocculation of 1 mm
limestone in the given place decreases heat-transmission from metal to water by about 10 %. Heating systems
with an open expansion tank allow a direct contact of heating water with the atmosphere. During the heating
period the expanding water in the tank absorbs oxygen, which increases corrosive effects and at the same
time water is significantly evaporated. To refill, you can only use water prepared to the values according to
ČSN 07 7401. It is necessary to rinse out the heating system properly in order to ensure washing-away of all
impurities. During refilling the heating system by water, it is necessary to be particular about not suction air into
the system. Water from the boiler and the heating system never may be discharged or taken off for using,
except of cases necessarily needed, such as repairs and so on. By discharging and refilling of new water, you
increase a danger of corrosion and creating a scale. If you need to add water into the heating system, add
it only to a chilled boiler to avoid a damage of the heat-exchanger.
b) Tightness of the heating system;
c) Connection to the chimney – it has to be approved by a chimney-sweep company;
A necessary condition for operation of this boiler is the flue lining from the reason of possible creation
of condensate in flue gases due to their low temperature, mainly at the minimum power of the boiler.
The flue lining material has to be resistant against chemical effects of condensate.
d) Tightness of the burner;
e) Connection to the electric power supply network;
The boiler has to be connected by a flexible cord by means of a plug into a normalized socket of 230 V/
50 Hz/10 A. A protection from electrical injury has to be ensured according to ČSN 33 2000-4-41 ed. 2.
Completion of mounting and performance of a heat test has to be recorded to the “Warranty certificate”.

3.
Connect the equipment to the power supply network (insert the plug into the socket).
Verify a correct connection and functionality of the connected electric devices.
Before commissioning of the burner it is necessary to check all connections and joints of the burner with the
feeder. Further check screws fixed the burner to the boiler and sealing between the burner and the boiler.
4. By pressing the rotating button and its subsequent rotation, select a mode Menu/Manual control.
5. Fill-in the fuel reservoir with prescribed fuel. After the reservoir is filled up, close it properly in order to prevent
possible suction of air into the burner through the feeder.
6. Pull out the orifice of the transport hose from the filling throat of the burner, and insert the hose, for example,
into a tank, a PE pack, etc.
• Select a mode Menu/Manual control/Feeder/On
• Wait until the fuel feeder is filled up by pellets (pellets are to be spilled into a prepared tank).
• Switch-off the feeder in Menu/ Manual control/Feeder/Off.
• Fix back the orifice of the transport hose to the filling throat of the burner.
• Perform calibration of fuel supply in menu Service settings (code 1992)/Burner settings/Others/Fuel
calibration (see Instructions Manual for the regulator SControl).
7. Check parameters setting in the control unit
8. Perform boiler kindling. Press the rotating button and subsequently rotate it to select Menu/Switch on regulator.
9. Check repeatedly boiler tightness.
10. Perform a heat test according to corresponding norms (see the Warranty certificate).

Boiler settings → Required boiler temperature
Mixer settings 1-5 → Required temperature
Parameter value: The regulator ignores the required boiler temperature in case that the required boiler temperature
is controlled by an outside sensor. Independently on it, the required temperature in the boiler is automatically
increased in order to enable to fill-up of the hot technical water reservoir and supply the mixers heating circuits.

Control, regulating and safety elements
6.3.1
Safety thermostat
A safety thermostat is placed on the Bottom part of the control box and serves for stopping the boiler course at
exceeding the safety temperature. It is necessary to set the safety thermostat to the temperature value of 100 °C,
°
i.e. to a higher temperature, than the maximum adjusted boiler temperature (90 C). After opening of the safety
thermostat, an indicator lamp of signalization of the safety thermostat is lit up. The fuel feeder and the fan will be
stopped. Unblocking of the safety thermostat has to be performed manually – to do it, demount the hole cover and
press a disk.
In case of repeated switching-off of the safety thermostat, it is necessary to switch-off it and find out a cause of
repeated boiler overheating. After the safety thermostat opening the primary pump (or the heating circuit pump)
continues to work.

Maintenance
7.1
Clean-up of the boiler
1.) Remove regularly ash from the heating chamber and the ash-drawer. Ash has to be laid into inflammable tanks
with a cover. Use protective equipment and observe personal safety during work.
2.) At least 1 h before clean-up of the boiler it is necessary to switch-off it (including electrical
disconnection). Frequency of boiler cleaning depends on fuel quality. In case of pellets with ash content up to
0,5 %, perform cleaning-up with 3 – 4 weeks intervals. Pellets with ash content 1,5 % and more cause that the
boiler has to be checked and cleaned once a week, or more often when necessary. Boiler clean-up means
removal of ash or deposits from the boiler drum (the heating chamber, the flue gases channel, etc.).
3.) The burner grate has to be regularly cleaned-up (in dependence on boiler operation). After the heating chamber
cooled down, take off the grate, throw out crusted ash by tapping and check the passability of holes for air
supply. It is necessary to use protective gloves.
4.) It is necessary to observe timely fuel stocking. If only small quantity remains in the reservoir, it is necessary to
refill it immediately to avoid suction of “false” air.
5.) We recommend cleaning-up regularly the transport hose, because fine particles are deposited during fuel
transportation inside the hose, which could finally prevent from passage of fuel through the hose. Beside of that
the deposited layer of fine fuel particles could inflame at a backward flame lash-up;
6.) After completion of cleaning-up or after whatever handling with the fuel feeder, check a correct fixation of the
transport hose on both its ends with help of hose clips.
7.) For a light overpressure in the heating chamber space during operation of the fan, be particular about excellent
tightness of the boiler (the cleaning door, the cleaning cover of the chimney pot, etc.).
It is prohibited to uncover the burner or whatever other intervention to these units for the boiler personnel.
These operations may only be performed by a service specialist.
7.2
Clean-up of the burner
Attention! The equipment can be only maintained after disconnection of the boiler and the
burner from power supply network.

Photo sensor
The burner photo sensor has to be cleaned-up each 3 months with a fine clout.
After removal of the burner cladding, take off the photo sensor (1), clean it up and put it in again.
Install the burner cladding back.

7.2.2
Clean-up of the fuel feeder pipe
In case that a foreign thing gets in the fuel feeder pipe and blocks its operation, then the feeder motor will start to
overheat and the feeder sensor will shut down the boiler.
To remove the foreign thing from the feeder pipe, it is necessary:
1. Disconnect the regulator from electric power supply.
2. Demount the feeder motor.
3. Push out the auger.
4. Remove the foreign thing from the pipe of from the auger.
5. Mount the fuel feeder in the opposite order.
6. Check correct operation of the fuel feeder.

7.2.3
Clean-up of the burner
One of the causes of burner failures can be pollution of the burner. Depending on quality of used fuel, it is
necessary to clean where necessary the burner furnace from ash.
The burner is equipped with a removable furnace, see fig. No. 27.
Before extraction of the furnace, it is necessary to clean it up thoroughly so that ash doesn’t get during extracting to
the air supply chamber; afterwards you can extract the furnace and clean-up holes for air supply. You can use a
wire brush or a small rake for cleaning-up.
After cleaning-up the furnace, it is necessary to place it back into the burner. The furnace lock has to be precisely
placed in the burner, see fig. No. 28.
ATTENTION!
The furnace after burning-out of the burner can be permanently hot, that’s why it is
necessary to use proper protective equipment.
Fig. №. 27
Procedure for burner furnace extracting
Fig. №. 28
Correct placement of the burner furnace
An often cause of pollution of the burner is the burner switching-off on the main switch. Too quick shutting-down of
the air supply causes insufficient fuel combustion. On the following burner switching-on without its cleaning-up its
tarring can occur, whereas enough air quantity doesn’t flow through the holes plugged by impurities.
That’s why the Boiler Extinction procedure must be performed before its switching-off.

not allowed to leave children without supervision of adult persons near the boiler that are in service.
The boiler is not determined for using by persons (including children), whose physical, sensible or
intellectual inability or absence of experience and knowledge prevents from safety using of the
consumer, until they are under supervision or until they are instructed of using of the consumer by a
person responsible for their safety.
You should watch the children to ensure that they don’t play with the consumer.
A necessary condition for operation of this boiler is the chimney lining from the reason of possible
creation of condensate in flue gases due to their low temperature, mainly at the minimum boiler power.
A material of the chimney lining has to be resistant against chemical effects of condensate.
In case that a danger of occurrence and penetration of flammable vapors or gases into the boiler room,
or during works, whereat a temporary danger of a fire or an explosion occurs (sticking of the floor
covering, painting with flammable paints, etc.), the boiler must be in advance before work starting be
shut-down from operation.
Flammable liquids mustn’t be used for kindling in the boiler.
If necessary, inspection of flame can be performed by half-opening the upper door. However,
remember that in this state there is increased danger of flying-off of sparks into the boiler-room space.
After performance of the visual inspection of flame, it is necessary to close the door immediately and
thoroughly.
On putting the boiler into operation, it is necessary to perform adjustment of the boiler and emission
checking.
Any preheating during boiler operation is prohibited.
No subjects from flammable materials can be put on the boiler or in distance lower than the safety
distance.
During extraction of ash from the boiler, no flammable materials can be placed on the distance at least
1500 mm from the boiler. Ash has to be laid away into inflammable vessels with a cover.
After finishing the heating season, it is necessary to clean-up the boiler, including the flue gas ducting.
The boiler room has to be kept in a clean and dry state.
It is prohibited to intervene into the structure of the boiler installation.
ATTENTION! Insufficient fuel quality can significantly negatively influence the power and emission
parameters of the boiler.
During mounting, installation and operation of the consumer it is necessary to observe norms valid in
a corresponding target country.
We recommend servicing the boiler by a professional company, and that is after each heating season.
In case of non-observance of these conditions, no warranty repairs can be required.
