2-INSTALLATION INSTRUCTIONS
CONNECTION TO THE EXTERNAL AIR INTAKE
It is essential for the room where the product is installed to be adequately ventilated in order to guarantee sucient air for proper
combustion in the appliance. This is possible by means of suitable ventilation openings in the room itself or in an interconnected room
through a permanent opening between the rooms.
For this purpose, drill a hole on the outer wall close to the product with a minimum section of 80 cm² (11 cm in diameter or 10x10 cm if
rectangular, considering the protective grids), protected by a grid on the outside.
The air inlet must also:
• Be protected with a grid, 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 section by about 5%, whereas for longer ducts, increase it by 15%.
Remember that the ventilation grilles always have a useful section in cm2 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 company
for product operation.
IMPORTANT!
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; air inlets connected
to thermal units, garages, kitchens or bathrooms must be avoided.
CONNECTION TO THE CHIMNEY
The chimney is the fundamental element for smoke expulsion and must therefore comply with the following requirements:
• Be waterproof and thermally insulated.
• Be made of suitable materials that resist mechanical stress over time, heat, the eects of the combustion products and any
possible condensation.
• Have a vertical set-up with deviations from the axis of no more than 45° and free of bottlenecks.
• Must be suitable for the specic operating conditions of the product and have the CE marking (EN1856-1, EN1443).
• Must be adequately sized for the draught/smoke expulsion requirements that are necessary for the product to operate correctly
(EN13384-1).
• The internal section is preferably circular.
• In the case of a pre-existing product that has been used, it must be cleaned.
The chimney is fundamental for correct operation and safety of your product.
Hereunder are a few guidelines for a correct installation. Any alternative congurations must be suitably sized in accordance with the
general method of calculation of UNI EN 13384-1.
