2.13 ANTIFREEZE PROTECTION
The boiler has an antifreeze function that switches the burner on automatically when the temperature falls below 4°C (standard protec-
tion to minimum temperature of 0°C).
In order to guarantee the integrity of the appliance and the domestic hot water heating system in zones where the temperature falls below
zero, we recommend the central heating system is protected using anti-freeze liquid and installation of the Immergas Antifreeze Kit in
the boiler.
All information relative to the antifreeze protection is stated in (Parag. 1.4).
2.14 PROLONGED INACTIVITY
In case of prolonged inactivity (e.g. second home), we recommend:
1. to switch off the power supply;
2. to completely empty the heating circuit and the boiler D.H.W. circuit. In systems that are drained frequently, filling must be carried
out with suitably treated water to eliminate hardness that can cause lime-scale.
2.15 CLEANING THE CASE
1. Use damp cloths and neutral detergent to clean the boiler casing.
Never use abrasive or powder detergents.
2.16 PERMANENT SHUTDOWN
In the event of permanent shutdown of the boiler, contact professional staff for the procedures and ensure that the electrical, water and
gas supply lines are shut off and disconnected.
