2. Shut off the gas supply.
3. Keep the installation frost-free.
Do not shut-down the boiler if the installation can't be kept frost-free.
11.14 Frost protection
Caution
Drain the boiler and central heating system if you are not going
to use your home or the building for a long time and there is a
chance of frost.
The frost protection does not work if the boiler is out of
operation.
The built-in boiler protection is only activated for the boiler and
not for the system and radiators.
Open the valves of all the radiators connected to the system.
Set the temperature control low, for example to 10°C.
If the temperature of the central heating water in the boiler drops too low,
the built-in boiler protection system is activated. This system works as
follows:
If the water temperature is lower than 7°C, the pump switches on.
If the water temperature is lower than 4°C, the boiler switches on.
If the water temperature is higher than 10℃, the burner shuts down and
the pump continues to run for a short time.
To prevent the system and radiators freezing in frost-sensitive areas (e.g.
a garage), a frost thermostat or, if feasible, an outdoor sensor can be
connected to the boiler.
11.15 Cleaning the casing
1. Clean the outside of the appliance using a damp cloth and a mild
detergent.
