The boiler must be installed in a fixed loca-

tion and only by specialized and qualified

firms in compliance with all instructions

contained in this manual.

Furthermore, the installation must be in

accordance with current standards and

regulations.

2.1

BOILER ROOM

The 

“RMG Mk.II”

boilers with a rating of

more than 35 kW must be equipped with a

technical room whose dimensions and

requirements correspond to the current

safety standards. 

The minimum height of the boiler room

must comply with what is indicated in fig. 3

in relation to the overall thermal capacity. 

The minimum distance between the walls of

the room and the external points of the boi-

ler (right, left side, rear) must not be less

than 0.60 m. 

It is possible to place a number of appara-

tus next to each other, on condition that all

the safety and control devices can be

easily reached. In addition, to circulate air

in the room, air vents must be made on

the outside walls for which the surface

area must never be less than 3,000 cm

2

and 5,000 cm

2

for gas with a density

greater than 0.8.

2.1.1

Handling

Once the boiler is in its place of installation

and the packaging has been removed, pro-

ceed as follows if it must be moved (fig. 3/a):

– remove the casing cover;

– attach the lifting brackets (located on the

rear of the boiler) and fasten it in place
