2-INSTALLATION INSTRUCTIONS
CONNECTION TO THE EXTERNAL AIR INLET
It is essential for the room where the product is installed to be adequately ventilated in order to guarantee sufficient air for proper
combustion in the appliance.This can be set up using suitable ventilation openings in the same room or one that connects 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 grilles), protected by a grille on the outside.
The air inlet must also:
t
be protected with a grid, metal mesh, etc. without reducing the net section.
t
Be positioned in such a way so as not to be obstructed.
t
Allow maintenance to be performed.
t
Be directly interconnected with the room where the product is installed.
t
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 2 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!
The air flow can also be drawn from an adjacent room to that of the room where the product is installed, provided
the air can flow 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:
t
be waterproof and thermally insulated.
t
Be made of suitable materials that resist mechanical stress over time, heat, the effects of the combustion products and any possible
condensation.
t
Have a vertical set-up with deviations from the axis of no more than 45° and free of bottlenecks.
t
Must be suitable for the specific operating conditions of the product and have the CE marking (EN1856-1, EN1443).
t
Must be adequately sized for the draught/smoke expulsion requirements that are necessary for the product to operate correctly
(EN13384-1).
t
The internal section is preferably circular.
t
In the case of a pre-existing product that has been used, it must be cleaned.
t
The chimney must not be shared with other appliances.
The chimney is fundamental for correct operation and safety of your product.
Hereunder are a few guidelines for a correct installation. Any alternative configurations must be suitably sized in accordance with the
general method of calculation of UNI EN 13384-1.
