Checks during operation
• Turn the unit on as described in sec. 2.3.
• Make sure the fuel circuit and water systems are tight.
• Check the efficiency of the flue and air-fume ducts while the boiler is working.
• Check the correct tightness and functionality of the condensate elimination system
and trap.
• 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 phases.
• Check proper boiler lighting by doing several tests, turning it on and off with the room
thermostat or remote control.
• Using a combustion analyser connected to the boiler fume outlet, check that the
CO content in the fumes, with the boiler operating at max. and min. output, corre-
2
sponds to that given in the technical data table for the corresponding type of gas.
• Make sure the fuel consumption indicated on the meter matches that given in the
technical data table on sec. 5.4.
• Check the correct programming of the parameters and carry out any necessary cus-
tomization (compensation curve, power, temperatures, etc.).
4.3 Maintenance
Periodical check
To keep the unit working properly over time, it is necessary to have qualified personnel
make an annual check that includes the following tests:
• The control and safety devices (gas valve, flow meter, thermostats, etc.) must func-
tion correctly.
• The fume extraction circuit must be fully efficient.
• The airtight chamber must be sealed
• The air-fume end piece and ducts must be free of obstructions and leaks
• The condensate evacuation system must be efficient with no leakage or obstruc-
tions.
• The burner and exchanger must be clean and free of scale. When 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 airtight.
• The water pressure in the cold water system must be about 1 bar; otherwise, bring
it to that value.
• The circulation 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 boiler casing, panel and aesthetic parts can be cleaned with a soft damp
A
cloth, possibly soaked in soapy water. Do not use any abrasive detergents and
solvents.
4.4 Troubleshooting
Diagnostics
The boiler is equipped with an advanced self-diagnosis system. In case of a boiler fault,
the display will flash together with the fault symbol (detail 20 - fig. 1) indicating the fault
code.
There are faults that cause permanent shutdown (marked with the letter "A"): to restore
operation just press the RESET button (detail 8 - fig. 1) for 1 second or RESET on the
optional remote timer control if installed; if the boiler fails to start, it is necessary to firstly
eliminate the fault.
Other faults (marked with the letter "F") cause temporary shutdowns that are automati-
cally reset as soon as the value returns within the boiler's normal working range, except
for fault F37 which is reset by turning the unit off and then on again with button 14 of
fig. 1.
