1.3  AERATION AND VENTILATION OF 

THE INSTALLATION ROOMS.

The rooms must have one or more permanent 

openings for aeration on external walls. The 

openings used for aeration can be protected 

using metal grills, meshes and/or rain-proof fins 

as long as the net aeration surface is not reduced.

Aeration for installation in outdoor places.

 The 

minimum free surfaces, in relation to the overall 

heat input must not be below:

a)  above-ground rooms (S ≥ Q x 10)
    S > 350 cm

2

 for every Victrix Pro 35 1 I

    S > 515 cm

2

 for every Victrix Pro 55 1 I

    (ex: to install 3 Victrix Pro 35 1 I in cascade, 

the minimum surface is 350 x 3 = 1050 cm

2

)

b)  basements and underground rooms up to a 

height of -5 m from the reference surface (S 

≥ Q x 15).

    S > 525 cm

2

 for every Victrix Pro 35 1 I

    S > 775 cm

2

 for every Victrix Pro 55 1 I

    (ex: to install 3 Victrix Pro 35 1 I in cascade, 

the minimum surface is 525 x 3 = 1575 cm

2

)

c)  underground rooms at quota between -5 m 

and -10 m from the reference surface (S ≥ Q 

x 20 with a minimum of 5000 cm

2

).

    S > 5000 cm

2

 for all configurations

In all cases each opening must not have a net 

surface area less than 100 cm

2

.

Attention:

 in the case of installation of appliances 

powered with gas with greater density than 0.8 

(L.P.G.) in outdoor places, above-ground, at least 

2/3 of the aeration surface must be flush with the 

floor, with a minimum height of 0.2 m. 

The aeration openings must be at least 2 m for 

heating capacities not exceeding 116 kW and 4.5 

m for higher heating capacities, cavities, depres-

sions or openings communicating with rooms 

below the walkway surface or draining ducts.

Aeration for installation in building also des-

tined for other use or in places inserted in the 

volume of the building served.

 The aeration 

surface must not be less than 3000 cm

2

 in the case 

of natural gas and must not be less than 5000 cm

2

 

in the case of L.P.G..
The installation must comply with the require-

ments of all relevant codes and standards.

1.4  OUTDOOR INSTALLATION.

The boiler has an IPX5D electric insulation rat-

ing and can also be installed outdoors, without 

additional protections.

Attention:

 all optional kits that can be potentially 

connected to the boiler must be protected on the 

basis of their electrical protection rating.

1.5  ANTI-FREEZE PROTECTION.

Minimum temperature -5°C.

 The boiler comes 

standard with an anti-freeze function that ac-

tivates the pump and burner when the system 

water temperature in the boiler falls below 5°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;
- Main switch is inserted;
- the boiler is not in no ignition block (Par.
-  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 failed ignition block), the 

appliance can freeze.

To prevent the risk of freezing follow the instruc-

tions below:

-  Protect the central heating circuit from freezing 

by inserting a good-quality antifreeze liquid 

into this circuit, which is specially suited for 

central heating systems and which is manu-

facturer 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 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 a potential water pollution class 2 

(EN 1717).

The materials used for the central heating circuit

 

of 

Immergas boilers withstand ethylene and propyl-

ene 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 relative 

drain against freezing by using an accessory 

supplied on request (anti-freeze kit) comprising 

two electric resistances, the relevant cables and 

a control thermostat (carefully read the instal-

lation 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;

-  main switch is inserted;
-  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 inter-

ruption of the electrical power supply and failure 

to comply with that stated on the previous page.
