Maintenance - Ferroli ENERGY TOP W 70 Instrucciones De Uso, Instalación Y Mantenimiento

Checks during operation
• Turn the unit on as described in sec. 1.3.
• 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
boiler operating at max. and min. output, corresponds 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. 4.4.
• Check the correct programming of the parameters and carry out any necessary customization (compensation curve,
power, temperatures, etc.).

3.3 Maintenance

Periodical check
To keep the unit working properly over time, it is necessary to have qualified personnel make an annual check that in-
cludes the following tests:
• The control and safety devices (gas valve, flow meter, thermostats, etc.) must function 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 obstructions.
• 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 cloth, possibly soaked in soapy
A
water. Do not use any abrasive detergents and solvents.
