4.2 Commissioning
Before lighting the boiler
•
Check the seal of the gas system.
•
Check correct prefilling of the expansion tank.
•
Fill the water system and make sure all air contained in the boiler and the system
has been vented.
•
Make sure there are no water leaks in the system, DHW circuits, connections or boil-
er.
•
Check correct connection of the electrical system and efficiency of the earthing sys-
tem.
•
Make sure the gas pressure for heating is that required.
•
Make sure there are no flammable liquids or materials in the immediate vicinity of
the boiler
B
IF THE ABOVE INSTRUCTIONS ARE NOT OBSERVED
THERE MAY BE RISK OF SUFFOCATION OR POI-
SONING DUE TO GAS OR FUMES ESCAPING; DAN-
GER OF FIRE OR EXPLOSION. ALSO, THERE MAY
BE A RISK OF ELECTRIC SHOCK OR FLOODING THE
ROOM.
Checks during operation
•
Switch the unit on.
•
Check the tightness of the fuel circuit and water systems.
•
Check the efficiency of the flue and air/fume ducts while the boiler is working.
•
Make sure the water is circulating properly between the boiler and the systems.
•
Make sure the gas valve modulates correctly in the heating and domestic hot water
production stages.
•
Check correct boiler lighting by performing various tests, turning it on and off with
the room thermostat or remote control.
•
Make sure the fuel consumption indicated on the meter matches that given in the
technical data table in cap. 5.
•
Make sure that with no demand for heating, the burner lights correctly on opening a
hot water tap. Check that in heating mode, on opening a hot water tap, the heating
circulating pump stops and there is regular production of hot water.
•
Make sure the parameters are programmed correctly and carry out any required
customisation (compensation curve, power, temperatures, etc.).
4.3 Maintenance
IMPORTANT
B
ALL MAINTENANCE WORK AND REPLACEMENTS
MUST BE CARRIED OUT BY SKILLED QUALIFIED
PERSONNEL.
Before carrying out any operation inside the boiler,
disconnect the power and close the gas cock up-
stream. Otherwise there may be a danger of explo-
sion, electric shock, suffocation or poisoning.
