Maintenance - Ferroli DOMIcompact F 24 B Instructions For Use, Installation And Maintenance

Checks during operation
• Check the soundness of the gas circuit and water systems.
• Check the efficiency of the flue and air-flue ducts while the boiler is working.
• Check that the water is circulating properly between the boiler and the systems.
• Make sure that the gas valve modulates correctly in both the heating and hot water production
modes.
• Check for correct ignition of the boiler by performing various tests, turning it on and off with the room
thermostat or remote control.
• Make sure that the gas consumption indicated on the meter corresponds to that given in the technical
data table in chap. 4.(Input rating)
• Check there is the correct flow rate of hot water with the
measurement should be made with specific instruments and as close as possible to the boiler, also con-
sidering the heat lost from the pipe work.
• Make sure that with no call for heating the burner ignites correctly upon opening a hot water tap. Check
that during heating operation, on opening a hot water tap, the heating pump stops and there is a con-
stant production of hot water.
Turning off
Turn the knobs (ref. 1 and 2 Fig. 1) onto minimum.
When the boiler is turned off, the printed circuit board is still powered.
Hot water and heating operations are disabled, the display shows
remains active..
The frost protection system will not work if the electricity and/or gas supply to the boiler are
cut off.
To avoid damage caused by freezing during long shutdowns in winter, it is advisable to drain all
water from the boiler, both tap and the system water; or drain off just the tap water and add a
suitable antifreeze to the heating system, as prescribed in chap. 2.3.

3.3 Maintenance

The following operations must only be carried out by suitably trained and Qualified Personnel,
such as Ferroli service engineers.
Seasonal inspection of the boiler and flue
It is advisable to carry out the following checks at least once a year:
• The control and safety devices (gas valve, flow switch, thermostats, etc.) must function correctly.
• The air-flue terminal and ducts must be free of obstructions and leaks.
• The gas and water systems must be sound.
• The burner and exchanger must be clean. Follow the instructions in the next paragraph.
• The electrode must be free of debris and correctly positioned.
• The water pressure in the cold water system must be approximately 1 bar; otherwise, bring it to that
value.
• The expansion tank must be filled with air @ 1bar.
• The gas flow and pressure must correspond to that given in the respective tables.
• The circulation pump must be manually spun, vented and not be restricted.
• The condensate discharge must be clean, free of obstructions, leaks and clean out the sediment inspec-
tion bowl.
Opening the casing
To open the boiler casing:
1 Unscrew the two screws A
2 Lower the instrument panel
3 Drop down the instrument panel
4 Fully unscrew the two screws B
