Periodical check
To ensure proper operation of the unit over time, have qualified personnel carry out a yearly in-
spection, providing for the following checks:
• The control and safety devices (gas valve, thermostats, etc.) must function 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. Use suitable brushes for clean-
ing. Never use chemical products to clean the burner.
• The electrode must be properly positioned and free of any deposits.
The electrode can be cleaned of incrustations only with a non-metallic brush, and must NOT
be sanded.
• The gas and water systems must be tight.
• The water pressure in the system when cold must be approx. 1 bar; otherwise bring it to that
value.
• The circulating pump must not be blocked.
• The expansion vessel must be filled.
• The gas flow and pressure must match that given in the respective tables.
• The condensate evacuation system must be efficient with no leakage or obstructions.
• The trap must be full of water.
• Check the quality of the water in the system.
• Check the condition of the exchanger insulation.
• Check the gas connection between the valve and Venturi.
• Replace the burner gasket if damaged.
• After checking, always control the combustion parameters (see "checking the combustion val-
ues").
Extraordinary maintenance and replacement of components
After replacing the gas valve, burner, electrode and PCB, it is necessary to do the calibration pro-
cedure [AUTO SETUP] (see "Calibration procedure [AUTO SETUP]" on page 314). Then follow
the instructions in par. "Checking the combustion values" on page 313.
