3.2 Start-up

B
Commissioning must be carried out by Qualified Personnel such as the staff of
our Sales Organisation and your local After-Sales Technical Service.
First lighting is free of charge and must be requested as indicated on the sticker
on the boiler.
Checks to be made at first lighting, and after all maintenance operations that involved
disconnecting from the systems or work on safety devices or parts of the boiler.
Before lighting the boiler
• Open any on-off valves between the boiler and the systems.
• Check the tightness of the gas system, proceeding with caution and using a soap
and water solution to detect any leaks in connections.
• Check the correct preloading of the expansion tank (ref. sec. 4.3)
• Fill the water system and make sure that all air contained in the boiler and the sys-
tem has been vented by opening the air vent valve on the boiler and any vent valves
on the system.
• Make sure there are no water leaks in the system, hot water circuits, connections or
boiler.
• Check the correct connection of the electric system and the functioning of the earth
system. l
• Check that the gas pressure value for heating is as required.
• Make sure there are no flammable liquids or materials in the immediate vicinity of
the boiler

Boiler lighting
• Open the gas cock ahead of the boiler.
• Vent the air from the pipe ahead of the gas valve.
• Turn on or insert any switch or plug ahead of the boiler.
• If the display shows the message OFF, press the button M (detail 7 - fig. 1) for 5 sec-
onds.
• Set the boiler to winter mode.
• Adjust the heating temperature to a value above 50°C and the possible room ther-
mostat to the required temperature value. The burner will now light and the boiler
starts working automatically, controlled by its adjustment and safety devices.
B
If the burners do not light and the "block" indicator comes on after correctly car-
rying out the lighting procedures, wait approx. 15 seconds then press the button
R (detail 6 - fig. 1). The reset control unit will repeat the lighting cycle. If the
burners do not light after the second attempt, consult the section "Troubleshoot-
ing".
In case of a power failure while the boiler is working, the burners will go out and
A
automatically relight when power is restored.
Checks during operation
• Ignite the appliance as described in sec. 1.3.
• Check the airtightness of the fuel circuit and water systems.
• Check the efficiency of the flue and air-fume ducts while the boiler is working.
• Check that the water is circulating properly between the boiler and the systems.
• Make sure that the gas valve modulates correctly in both the heating and hot water
production phases.
• Check the proper ignition of the boiler by performing various tests, turning it on and
off with the room thermostat or remote control.
• Make sure that the fuel consumption indicated on the meter corresponds to that giv-
en in the technical data table in sec. 4.3.
• Make sure that with no call for heating the burner correctly ignites on opening a hot
water tap. Check that during heating operation, on opening a hot water tap, the heat-
ing circulator stops and there is a regular production of hot water.
• Check the parameters are programmed correctly and perform any required custom-
ization (compensation curve, power, temperatures, etc.)

3.3 Maintenance

B
The following operations must only be carried out by Qualified Personnel.
Periodical check
To ensure proper operation of the unit over time, have qualified personnel carry out a
yearly check, providing for the following:
• The control and safety devices (gas valve, flowmeter, thermostats, etc.) must func-
tion correctly.
• The fume exhaust circuit must be perfectly efficient.
(Sealed chamber boiler: fan, pressure switch, etc. - The sealed chamber must be
tight: seals, cable glands, etc.)
(Open chamber boiler: anti-backflow device, fume thermostat, etc.)
• The air/fume terminal and ducts must be free of obstructions and leaks
• The burner and exchanger must be clean and free of deposits. For cleaning do not
use chemical products or wire brushes.
• The electrode must be free of scale and properly positioned.
• The gas and water systems must be tight.
• The water pressure in the cold water system must be approx. 1 bar; otherwise bring
it to that value.
• The circulating pump must not be blocked.
• The expansion tank must be filled.
• The gas flowrate and pressure must match that given in the respective tables.
The boiler casing, control panel and aesthetic parts can be cleaned with a soft
A
damp cloth, if necessary soaked in soapy water. Do not use any abrasive de-
tergents and solvents.
