FROST DEVICE
The boiler is fitted with a device which, in the event that the
water temperature falls below 3˚C, the burner ignites at
the minimum power until the boiler reaches a temperature
of approximately 33˚C in the heating circuit.
This device only operates if the boiler is functioning
perfectly and:
- the system pressure is sufficient;
- the boiler is powered electrically;
- the gas is turned on.
