4.2 Startup
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 boiler.
• Check correct connection of the electrical system and efficiency of the earthing system.
• 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
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.
• Check the correct tightness and efficiency of the condensate removal system and trap.
• Make sure the water is circulating properly between the boiler and systems.
• Make sure the gas valve modulates correctly in heating and domestic hot water pro-
duction.
• Check proper lighting of the boiler by turning it on and off several times with the room
thermostat or remote control.
• Make sure the fuel consumption indicated on the meter matches that given in the
technical data table on cap. 5.
• Make sure that with no heating demand the burner correctly lights on opening a hot
water tap. Check that the heating circulating pump stops on opening a hot water tap
during heating operation and there is a regular production of hot water.
• Check correct programming of the parameters and carry out any required customi-
sation (compensation curve, power, temperatures, etc.).

4.3 Maintenance
Opening the front panel
To open the boiler casing:
1. Partially undo the screws A (see fig. 24).
2. Pull the panel B towards you and release it from the upper fastenings.

Before carrying out any operation inside the boiler, disconnect the power supply
and turn off the gas valve upstream

On this unit, the casing also acts as a sealed chamber. After any opera-
tion involving opening the boiler, carefully check the correct refitting of
the front panel and its seal.
Proceed in reverse order to refit the front panel. Make sure it is correctly hooked to the
upper fastenings and is correctly positioned at the sides. When tightened, the head of
screw "A" must not be below the lower fold (see fig. 25).

Periodical check
To ensure proper operation of the unit over time, have qualified personnel carry out a
yearly inspection, providing for the following checks:
• The control and safety devices (gas valve, flow meter, thermostats, etc.) must func-
tion correctly
• The fume exhaust circuit must be perfectly efficient
• The sealed chamber must be tight
• The air-fume end piece and ducts must be free of obstructions and leaks
• The burner and exchanger must be clean and free of deposits For possible cleaning
do not use chemical products or wire brushes
• The electrode must be properly positioned and free of scale
• The gas and water systems must be tight.
• The water pressure in the cold water system must be about 1 bar; otherwise, bring
it to that value
• The circulating pump must not be blocked.
• The expansion tank must be filled.
• The gas flow and pressure must correspond to that given in the respective tables
• The condensate evacuation system must be efficient with no leakage or obstruc-
tions
• The trap must be full of water.
