1.4 ANTIFREEZE PROTECTION
Minimum temperature 0°C
The boiler is equipped as standard with an antifreeze function that starts the pump and burner when the water temperature inside the
boiler drops below 4°C.
In these conditions the boiler is protected against freezing to an ambient temperature of 0°C.
If the boiler is installed in a place where the temperature drops below 0°C, the appliance can freeze.
To prevent the risk of freezing follow the instructions below:
The excessive use of glycol could jeopardise the proper functioning of the appliance.
- Protect the central heating circuit from freezing by inserting a good-quality antifreeze liquid into this circuit, which is especially suit-
ed for central heating systems and which is manufacturer guaranteed not to cause damage to the heat exchanger or other components
of the boiler. The antifreeze liquid must not be harmful to one's health. The instructions of the manufacturer of this liquid must be fol-
lowed scrupulously regarding the percentage necessary with respect to the minimum temperature at which the system must be kept.
- The materials used for the central heating circuit of Immergas boilers resist ethylene and propylene glycol based antifreeze liquids (if
the mixtures are prepared perfectly).
- An aqueous solution must be made with potential pollution class of water 2 (EN 1717:2002 or local standards in force).
For life and possible disposal, follow the supplier's instructions.
