15. HANDING THE BOILER OVER TO THE CUSTOMER

After mounting a boiler, a specialist of the service department is obliged to check boiler's operating at minimal
and maximal power in all modes (see section
11
section ).
After completion of installation and adjustment works, user should be instructed about boiler's treatment:
 Safety precautions when applying the boiler;
 Procedure of switching on/off a boiler;
 Management of a boiler;
 Treatment of a boiler performed by the user.
In the section 22 (page 41) of present user's manual should be indicated the instruction conduction. There should
also be a mark about boiler mounting.
16. TECHNICAL SERVICE AND OPERATION CHECK
Technical service and operation check should be performed by a special service organization.
Caution! Activities related to the technical service don't go under the warranty of company- manufacturer
and paid by the consumers.
During annual technical service it is necessary to carry out the following:
1) Cleaning of the burner block (burner) including wiping of ignition and ionization plugs (see p.
2) Cleaning of the heat exchanger from soot and cleaning (wiping) of tubes of heat exchanger from scale (if
necessary) (see p.
3) Replace seals in gas and water systems (in such connections where disassemble of water and gas pipes or in
the places where water or gas leakage occur);
4) Check air-tightness of boiler's water and gas systems;
5) Lubricate moving connections (if necessary), dense based on silicon lubricants are recommended;
6) Check operation of safety devices and sensors(see p.16.2.2, page. 34);
7) Check air pressure in the extension tank (once per 3 years);
8) Check air duct system and removal of combustion products on leakage;
9) Check water flow in DHW (should be enough for switching DHW mode on);
10) Check the heating system on contamination.
Caution! Operations related to technical maintenance of the boiler, disassemble of its gas and water pipes,
are necessary to perform only when the boiler is completely switched off (taps on boiler's inlet water and gas
lines should be closed, boiler should be disconnected from the power ).
16.1. Technical service
16.1.1 Cleaning the burner block
Caution! Keeping burner block in pure conditions will protect heat exchanger from the soot and increase its
service live.
To clean the burner block 5 (p.13.1, page24) it is necessary:
1) To dismount a burner (see p.
2) Remove dust by the brush from the external burner's surfaces and manifold;
3) Remove carbon deposit with the sandpaper from the ignition and ionization electrodes;
4) Wipe with wet rag manifold and nozzles;
5) Remove dust with a brush-cleaner out of inner channels of the burner blade;
6) Wash a burner in soup water, particularly spaces of its sections by means of the brush-cleaner, thoroughly
wash it in running water, dry and then put it back;
7) Check joints on leak-proof subject to disassembling (see p.16.2.1, page 33);
8) Check if ignition plug is on the distance 5
9) Check if ionization plug is on the distance 3
It is necessary to check whether burner's sections and nozzles are not damaged.
Reason of failure
Power voltage is over 190 ÷ 250 V
11
, page 22). Gas supply regulator should be obligatory adjusted (see
16.1.2 16.1.3
; p. , page 33);
17.1
, page 36);
+ 0,5
Restore power voltage in range 190 ÷ 250 V.
Within 30 seconds will be automatic boiler's
start up in the previous mode that boiler used
to be before the power voltage went over the
range 190 ÷ 250 V
mm above the burner blade;
