ENGLISH
The appliance must not be installed in small rooms, bedrooms, bathrooms or in areas with an explosive atmosphere.
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 80 cm away from the top part of it.
Furniture and movable objects made from flammable materials must be positioned at least 20 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.
Any extra intervention by the Authorised technical assistance centre, which requires the appliance to be disconnected from the system,
will not be covered under warranty as described in the chapter
“Standard Warranty Conditions”
.
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
2
(round hole with minimum
diameter of 15 cm protected with a special fixed large mesh grille).
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.
Smoke ducts and connection to the flue
The
flue
is an essential element for the efficient operation of the appliance. The flue must have the minimum cross-sectional dimensions stated in the
appliance’s technical specifications (120 mm). Each product must be equipped wi
th its own flue, without other adjoining elements (boilers, chimneys,
stoves, etc.). The flue dimensions are closely related to its height, which must be measured from the appliance flue gas outlet to the base of the stack.
In order to guarantee adequate draught, the surface of the chimney flue outlet must be double the flue cross-section. The discharge pipe for combustion
products generated by the forced draught device, must comply with the following requirements:
-
It must seal off the combustion gases, as well as being waterproof and suitably isolated and insulated in relation to the conditions of use (refer to
UNI 9615);
-
It must be made of suitable materials capable of withstanding normal mechanical stress, heat, and the effects of combustion gases and
condensate, if any;
-
It must go upwards after the vertical section, for the entire remaining part, with a minimum gradient of 5%. The sub-horizontal section must not
be longer than ¼ of the effective height H of the flue or chimney, and
must not be longer than 2,000 mm
