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 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 cleaning. Never use che-
mical products.
•
The electrode must be properly positioned and free of scale.
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 tank 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 insulation of the exchanger.
•
Check the gas connection between the valve and Venturi.

Replace the burner gasket if damaged.
•
At the end of the check, always check the combustion parameters (see "checking the combustion values").
