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, sensors, 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 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 insulation of the exchanger.
•
Check the gas connection between the valve and Venturi.
•
Replace the burner gasket if damaged.
•
After the check, always control the combustion parameters (see "checking the combustion values").
Cleaning the exterior surfaces
So as not to alter the opacity of the painted plastic
panel (ref. A fig. fig. 33) use mild degreasers that do
not contain Mek or aggressive alcohols.
To clean the glass panel (ref. B fig. fig. 33), use iso-
propyl alcohol.
To clean the side panels (ref. C fig. fig. 33), use a mild
detergent.
