Details of the product are written on the outside: model, power, 

version and type of fuel. Contact your local dealer in case of any 

differences with the order.

Ensure the goods are intact and complete after unpacking them.

 

9

Do not leave the packaging within the reach of children as it 

could be a potential source of danger.

The tag on the front side of the boiler’s electrical board, contains 

the following information:

 

− Product name

 

− Serial number

 

− Product identification code

 

− CE certification number

 

− Gas type and pressures from mains

 

− Power type from mains

 

− Rated heat capacity (Qn)

 

− Rated working power (Pn)

 

− Efficiency according to 92/42/EEC Directive 

(η)

 

− Max pressure and temperature (Pms)

 

− Primary system (T)

 

− NOx class (NOx)

It  is  forbidden  to  remove  or  mishandle  the  identification 

plates, markings and any other making it difficult to safely 

identify the product.

4.2 

Installation premises

The heating unit must be installed in premises used exclusively 

for the latter conforming to standards and legislation in force 

and where combustion exhaust products and combustion air 

intake is conveyed out of said premises. Where combustion air is 

instead taken from the installation premises then the latter must 

be equipped with suitably sized vents conforming to standards.

 

9

The space required to reach the safety and adjustment de-

vices and to carry out maintenance must be considered. We 

recommend leaving a space of at least 500 mm at the back 

of the appliance.

 

9

Ensure that the degree of the heating unit’s electrical pro-

tection is compatible with the characteristics of the instal-

lation premises.

 

9

Electrical parts must be placed at a height of no less than 

500 mm from the ground where heating units are supplied 

with fuel gas with specific weight exceeding that of air.

 

9

Heating units may not be installed out in the open (unless 

they are not specific outdoor units).

 

9

The heating unit is equipped with a frost protection func-

tion, useful for installations where the temperature of the 

environment could be below 0°C. Gas and electricity must 

be supplied for this system to work, apart from a correctly 

pressurized water circulation system and the system must 

not be in shutdown due to any type of error.
