5.5 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”.

5.6 Boiler commissioning

1. Connect the equipment to the power supply network (insert the plug into the socket). 2. Verify a correct connection and functionality of the connected electric devices. 3. 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). 11. Acquaint the user with handling. 12. Made a record in the Warranty certificate.

Commissioning of the boiler may only perform a professional mounting companies authorized for this activity.

6.3 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.

7 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.

7.2.1 Photo sensor

1. The burner photo sensor has to be cleaned-up each 3 months with a fine clout. 2. After removal of the burner cladding, take off the photo sensor (1), clean it up and put it in again. 3. Install the burner cladding back.

Fig. №. 25

1. Photo sensor

24

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. 29. 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. №. 26 Procedure for burner furnace extracting

Fig. №. 27 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.

7.3 Mounting of the additional module B (A2)

The module is not a part of the boiler standard supply – it is only on request. It serves for the extension of the heating system by the next two circuits. It cooperates with the storage reservoir.

Mounting of the control box

Pull the fork of the supply cable from the 230 V socket.

Place the module B on the DIN-rail and secure it with latches (power supply of 230 V has to be directed out of the electric cabinet).

Disconnect the conductors of 230 V (No. 71/72, No. 1/2, No. 40/41) from the terminal board (fig. No. 31) and connect it to the terminal board of the module B (A2):

8 IMPORTANT WARNINGS

The boiler may be only used for the purposes, which it is determined for.

The boiler may only operate persons, who are adult and acquainted with this instruction manual. It is 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.
