2-INSTALLATION INSTRUCTIONS

OUTDOOR AIR INLET

Drill a hole on the outer wall close to the product with a minimum section of 100 cm² (13 cm in diameter or 12x12 cm if square, considering

the protective grids), protected by a grid on the outside.

The air inlet must also:

• be protected with grilles, metal mesh, etc. without reducing the net section;

• be positioned in such a way so as not to be obstructed;

• allow maintenance to be performed;

• be directly interconnected with the room where the product is installed;

• in the case of ducting, up to 3.5 linear metres, increase the cross-section by about 5%, whereas for longer ducts, increase it by 15%.

Remember that the ventilation grilles always show the useful section in cm

on one side.

When choosing the grille and size of the hole, check that the useful section of the grille is larger or equal to the

section required by the manufacturer for product operation.

IMPORTANT!

The air ow can also be drawn from an adjacent room to that of the room where the product is installed, provided

the air can ow freely through permanent openings interconnected with the outside; it is forbidden to connect to

thermal units, garages, kitchens or bathrooms.

CONNECTION TO THE CHIMNEY

The connection to the closed replace is very important and must be implemented carefully. The products have an upper or rear smoke

exhaust. The smoke exhaust pipe must be assembled in such a way so as to guarantee its tightness during product operation in negative

pressure and prevent condensation from being formed and conveyed towards the product.

Any manual draught control devices inserted in the pipe should not hermetically seal the internal section of the duct. These dampers

must be equipped with a suitable mechanism to prevent the valve from rotating completely in the closed position. The minimum safety

opening surface must be 3% of the through section and not less than 20 cm². If the smoke duct has a horizontal section, the same should

rise with a minimum slope gradient of 3-5% (3-5 cm per every metre).

The horizontal section of the smoke duct must not be longer than 2 m.

It is forbidden to use exible and bre cement pipes. The smoke duct must not cross rooms in which it is forbidden to

install combustion appliances. It is forbidden to use counter-sloping pipes.
