1.2  MAIN DIMENSIONS.

1.3  ANTI-FREEZE PROTECTION.

Minimum temperature -5°C. 

Minimum 

temperature -5°C. The boiler is supplied with 

an anti/freeze function as standard that activates 

the pump and burner when the system water 

temperature in the boiler falls below 4°C.

The anti-freeze function is only guaranteed if:

- the boiler is correctly connected to gas and 

electricity power supply circuits;

- the boiler is powered constantly;
- the boiler is not in 'no ignition block' mode 

(Par. 2.5);

-  the boiler essential components are not faulty.

In these conditions the boiler is protected against 

freezing to an ambient temperature of -5°C.

Minimum temperature -15°C. 

If the boiler is 

installed in a place where the temperature falls 

below -5°C and in the event there is no gas (or 

the boiler goes into ignition block), the appliance 

can freeze.

To prevent the risk of freezing follow the 

instructions below:

- protects the central heating circuit from 

freezing by introducing a top quality anti-freeze 

liquid into this circuit, which is not noxious to 

health. The instructions of the manufacturer 

of this liquid must be followed scrupulously 

regarding the percentage necessary with 

respect to the minimum temperature at which 

the system must be kept. An aqueous solution 

must be made with potential pollution class of 

water 2.

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).

For life and possible disposal, follow the 

supplier's instructions.

- Protect the condensate drain trap and circuit 

board against freezing by using an accessory 

that is supplied on request (anti-freeze kit) 

comprising two electric heating elements, 

the relevant cables and a control thermostat 

(carefully read the installation instructions 

contained in the accessory kit pack).

Boiler anti-freeze protection is thus ensured only if:

- the boiler is correctly connected to electricity 

power supply circuits;

- the main switch is on;
- the anti-freeze kit components are efficient.
In these conditions the boiler is protected against 

freezing to temperature of -15°C.
The warranty does not cover damage due to 

interruption of the electrical power supply and 

failure to comply with that stated on the previous 

page.

N.B.:

 if the boiler is installed in places where 

the temperature falls below 0°C, the heating 

attachment pipes must be insulated.
