INS ULA TION AND DIAME TE R OF HOLES IN WALLS OR ON THE ROOF
Once the position of the boiler is established and that you have checked that the place of installation is ideal, it
is then necessary to make the hole for passing tubes through the wall. This can vary according to the type of
installation, the diameter of the flue tube and the type of wall or roof that it must pass through.
N.B.: if the floor can not support the weight of the boiler, position a sheet plat form of the correct size with
insulation applied on the floor (rock wool) and with a nominal density greater than 80kg/mc.
END PART OF THE FLUE SYSTEM
The stack must not be installed in spaces that are closed, poorly ventilated or, in general, where fumes may
collect.
It is necessary to check that there are no flammable elements (plants, wood) or elements that could be visually
damaged (walls, windows) within 3m of the flue.

9. OXIDISING AIR INTAKE
Oxidising air can be tak en from the atmosphere as long as there is sufficient ventilation, otherwis e it is
necessary to take it from the outside: in this manner it is possible to guarantee an optimal combustion without
having t o open air intakes in the room. For both cases pleas e refer to t he installation regulations in vigour (UNI
10683 and UNI7129) to avoid health risks of those who in the room where the machine has been installed.
Do not use flexible tubes and place a grid over the entrance (external) of the tube in order to stop alien
elements entering the system which could jeopardise the correct functioning.
