3 5  Positioning the boiler 

and making the hydraulic 

connections

Before installing, check you have the necessary 

spaces for the system, considering the dimensions 

of the boiler, the flue gas discharge system, and the 

hydraulic circuit.

The boiler comes standard with a boiler support plate (F). 

The position and dimensions of the hydraulic connections 

are shown in detail. In addition, a cardboard template is 

included with the standard equipment to assist the installer 

in his work.

In order to mount the boiler directly on the wall, perform the 

following operations:

-  fasten the boiler support plate to the wall and use a 

level to make sure it is perfectly horizontal

-  mark the positions of the 4 holes for fastening the 

boiler support plate

-  make sure that all measurements are exact, then drill 

the wall using drill tips with the diameters indicated 

above

-  fasten the plate to the wall.

See the following diagram; if necessary, use the cardboard 

templates supplied along with the boiler.

Support frames for wall and floor applications are also 

available as an accessory.

In order to install the accessories, please refer to the in-

structions supplied along with them.

Complete the water connections and assemble the drain 

pipes for the safety valve and the 3-way valve.

After installing the boiler and connecting it to the water and 

gas supplies, fit the couplings cover.
