2.7 Antifreeze protection.
e boiler comes standard with an antifreeze function that
starts the pump and burner when the system water tem-
perature inside the boiler falls below 3°C. e antifreeze
function is guaranteed if the boiler is fully operative and not
in “block” status, and is electrically fed. To avoid keeping
the system operational in the event of prolonged absence it
must be drained completely or antifreeze substances must
be added to the heating system water. In appliances subject
to frequent draining, the system must be relled with suit-
ably treated water to eliminate hardness that may cause the
formation of scale.
2.8 Casing cleaning.
Use damp cloths and neutral soap to clean the boiler casing.
Never use abrasive or powder detergents.
2.9 Decommissioning.
In the event of permanent boiler decommissioning, have
professional personnel carry out the relevant procedures
and ensure that the electrical, water and gas supply lines are
disconnected.
