Periodic 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 cleaning.
Never use chemical products.
•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 val-
ue.
•The circulating pump must not be blocked.
•The expansion vessels must be loaded.
•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.
