Spaces around and above the boiler

The figure below indicates the minimum measurements to respect when positioning the boiler according to the walls.
Any shelves or suspending ceilings assembled above the boiler must be at least 40 cm away from its upper part.

External air vent

While it is running the boiler withdraws air from the environment in which it is installed; it is essential that the air is restored through an external air
vent.
If the wall behind the boiler is an outside wall, drill a 15 cm diameter hole at 20 cm from the ground (as Fig. A).
Furniture and mobile objects must be positioned at least 15 cm from the boiler side walls; these objects must be moved when servicing the boiler.
It is forbidden to hang shelves or build suspended ceilings above the boiler at a distance measuring less than 40 cm.
Protect all structures that can catch fire from heat radiation.
The hole must be protected externally with a fixed grid. Periodically ensure the grid is not obstructed by leaves or similar, thus blocking the air
passage.
If it is not possible to realise the air vent in the wall behind the boiler, make the hole in a perimeter wall where the boiler is installed.
If it not possible to realise the external air vent in the same room where the boiler is installed, this hole can be made in an adjoining room as long as this
room communicates permanently, by means of a transit hole (15 cm minimum diameter).
The UNI 10683 Standard PROHIBITS the withdrawal of combustion air from garages, combustible material warehouses, or from businesses
where there is a fire hazard.
Do not connect the external air vent to the boiler through piping. If there are other heating or suction appliances in the room, air vents must
guarantee an air volume required for the proper operation of all devices.
Only sealed equipment (e.g. C type gas equipment, according to the UNI 7129 Standard) or equipment that does not cause lower pressure
compared with the external environment can pre-exist or be installed in the place where the boiler must be installed.
Extractor fans can cause functioning problems to the boiler when they are installed in the same room or space where the appliance is found.
