or taken for usage except for cases of emergency cases like repairs etc. Water discharge and filling with
new water increases the danger of corrosion and scale development. In case we have to refill the
heating system with water we only do this operation when boiler is cold in order to prevent the
sections from getting damaged.
16. After having filled a boiler and heating system it is necessary to check all joints for their tightness.
The assembly completion and stoking tests accomplishment must be recorded in “Guarantee
certificate”.
7. Commissioning
Boilers commissioning, thermal output setting and any interference in electric part of boilers or
connection of other control elements can only be done by a contracting service organization
authorized to do the service works.
7.1 Verification before commissioning
Before boilers commissioning it is necessary to check:
a) heating system filling with water (thermo-manometer and system tightness check-up)
b) Boiler thermostat setting to 50 - 80
o
C
c) Fuel input pressure before the boiler (18 – 23 mbar for natural gas, furnace oil extra light (TOEL)
according to burner documentation)
d) Connection to electric network 230 V/50 Hz via a cable with a plug to a standardized socket secured by
10 A.
Č SN 33 2180 Art.. 6.2.2. – the sockets is carried out in a way making sure that the protective plug
is up and the inner or zero conductor is connected to right hand cup in the front view. The same applies
to double sockets.
e) Connection to the chimney – tightness and mechanical stability
7.2 Boilers commissioning
1. Burner assembly and its adjustment plus commissioning together with a burner must be done by a burner
supplier's service firm. The service firm will provide the user with a training in operating the burner, with
manual for burner operation and will ensure its guarantee and after guarantee repairs.
2. Gas or furnace oil extra light (TOEL) connection to the burner and electric network
3. Boiler commissioning– setting of required return water 50 – 80 °C temperature.
4. Operate boiler in this operating condition according to manual for usage
5. Make the user acquainted with boilers operation
6. Put down a record in Guarantee certificate.
8. Boiler operation by user
Boilers work automatically according to their regulation elements setting and users only have to do
regularly following operations that the worker who puts the boiler into operation is obliged to be
make them acquainted with:
1. Boiler switch off or switch on via the power supply switch on the boiler control panel.
2. Boiler operation control via the selectd regulation, according to operation manual.
3. Required heating water temperature setting and control in the range from 50 to 80°C. We
recommend to set this temperature in this range only at boilers without regulation. If a boiler is controlled
by an indoor thermostat or by some other type of regulation the boiler thermostat must in the maximum
temperature position.
4. In case there appears a boiler failure state the exceeded temperature signalling or burner defect
signalling will appear on boiler control panel.
5. In case of an electricity outage the burner is switched off and after the voltage has been restored in the
network the burner is restarted automatically.
6. Unblocking of safety thermostat. If the boiler has been switched of via the safety thermostat on the
control panel there is lit a lamp signalling the exceeded temperature. The thermostat can be unblocked by
user using the safety thermostat "reset” switch positioned in the network module on the control panel.
7. The pressure control in heating system – the pressure must not exceed 400 kPa (4 bar) and be lower
than minimum value set by the commissioning technician.
