FrostControl and fixed in place with a retaining bracket. This heating element heats the FrostControl
to approx. 10 °C when the Combi is switched on. This means that the boiler can be filled sooner,
irrespective of
the temperature in the installation compartment. Automatic opening of the
safety/drain valve If the temperature at the safety/drain valve is below about 3 °C,
it will open automatically and the pushbutton pops out).

B. Safety/drain valve (Safety/drain valve without frost protection / standard in UK version)

socket.
