Action in the event of a risk of
freezing
When it is extremely cold, no part of the heating system
must be switched off as there is a risk of bursting.
Never fire if you suspect that any part
of the heating system may be frozen.
Call an installation engineer.
Heating system switched off
If the heating system is to be switched off for an
extended period of time, the water should be drained.
Alternatively, anti-freeze can be added to the system
water.
Ensure that the anti-freeze contains a suitable quantity
of a corrosion-inhibiting additive.
Draining the boiler
The boiler must not be in operation when it is drained.
Close the valves for the heating system.
Drain the water to a floor drain via a hose connected
to the boiler’s drain valve.
Create air supply by opening the boiler’s safety valve.
Always cut the power to the boiler before
the boiler water is drained.
