Spaces around and above the appliance
The figure below shows the minimum distances from walls or other not-easily-removable furniture, that need to be taken into consideration when
positioning the appliance.
Any shelves or false ceilings mounted above the appliance must be at least 50 cm away from the top part of it.
Furniture and movable objects made from flammable materials must be positioned at least 50 cm from the side surfaces of the appliance; these objects
must be moved when performing maintenance on the appliance.
Protect all structures that can catch fire against the radiated heat of the fire.
External air intake
During operation, the appliance takes in air from the environment in which it is installed; It is therefore essential that this air is replaced through an
external air vent. The absence of the air vent may affect the flue draught and therefore the combustion and the safety of the appliance.
Therefore it is mandatory to install an external air vent with a minimum completely free passage of at least 80 cm
(round hole with minimum diameter
2
of 15 cm protected with a special fixed large mesh grid).
If the wall behind the appliance is on the outside, we recommend you make the hole near it at about 20 cm above the ground
(see example in Fig.
A).
If it is not possible to put an air vent in the wall behind the appliance, make a hole in a perimeter wall in the room where it is installed. If it not possible
to put the external air vent in the same room as where the appliance 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 hole must be protected externally with a fixed grille. The protective grille must be checked periodically to ensure that it is not obstructed, thereby
impeding the passage of air. Therefore keep the air vents clear of obstructions.
The UNI 10683 Standard FORBIDS the drawing of combustion air from garages, warehouses storing combustible materials, or from business premises
with a fire hazard.
If there are other heating or extraction devices inside the room, the air vents must guarantee a sufficient amount of air for properly operating all the
devices.
Only sealed appliances (e.g. C type gas appliances, according to the UNI 7129 Standard) or appliances that do not cause a lower pressure compared
with the external environment can pre-exist or be installed in the place where the appliance is installed.
Extractor fans can cause malfunctions to the appliance if used in the same room.
