In case of an electrical power failure while the boiler is working, the burners will go out and re-
ignite automatically when power is restored.
Checks during operation
• Check the airtightness of the fuel circuit and water systems.
• Check the efficiency of the flue and air-fume 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
phases.
• Check the proper ignition of the boiler by performing various tests, turning it on and off with the
room thermostat.
• Make sure that the fuel consumption indicated on the meter corresponds to that given in the technical
data table in chap. 4.
• Check there is the right flow rate of hot water with the t stated in the chart: do not trust measurements
made with empirical systems. The measurement should be made with specific instruments and as
close as possible to the boiler, also considering the heat lost from the pipes.
• Make sure that with no call for heating the burner correctly ignites on opening a hot water tap. Check
that during heating operation, on opening a hot water tap, the heating circulator stops and there is
a regular production of hot water.
Turning off
Close the gas cock ahead of the boiler and disconnect the electrical power.
To avoid damage caused by freezing during long shutdowns in winter, it is advisable to drain all
water from the boiler, the sanitary and the system water; or drain off just the sanitary water and
add a suitable antifreeze to the heating system.
3.3 Maintenance
The following operations must only be carried out by Qualified Personnel.
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, thermostats, etc.) must function correctly.
• The air-fume end piece and ducts must be free of obstructions and leaks.
• The gas and water systems must be airtight.
• The burner and boiler shell must be clean. Follow the instructions in the next paragraph.
• The electrodes must be free of scale and properly positioned (see fig. 10-11).
• The water pressure in the cold water system must be about 1 bar; otherwise, bring it to that value.
• The expansion tanks, if present, must be filled.
• The gas flow and pressure must correspond to that given in the respective tables.
• The circulating pumps must not be blocked.
Safety devices
The
Era F 30 B 60
boiler is equipped with devices that guarantee safety in the event of operation
anomalies:
Temperature limiter (safety thermostat)
This device prevents the water temperature in the system from exceeding boiling point. The maximum
intervention temperature is 100°C.
The thermostat tripping is signalled by the indicator light (
9
- fig. 1) blinking. To restore operation, take
off the cover (
6
- fig. 1) and press the button beneath.
