2-INSTALLATION INSTRUCTIONS

EXTERNAL AIR INLET

It is mandatory to provide an adequate external air intake that supplies the combustion air required for the product to work properly. The

ow of air between the outside and the installation room may be direct, through an inlet in an external wall of the room; or indirect, via

air intake from adjoining rooms and connecting permanently with the installation room (see Figure 9 b). Adjoining areas may not include

sleeping areas, garages or general areas with a re hazard. During installation one must check the minimum clearances required for air

intake from outside. Take into account the presence of doors and windows that could interfere with the proper ow of air to the stove (see

diagram below).

The air intake must have a minimum total net area of 80 cm2: the surface must be increased accordingly if within the room there are other

active generators (for example: electric fan for stale air extraction, kitchen hood, other stoves, etc...), which could cause cause depression

in the room. A check must be carried out to ensure that, with all equipment on, the pressure drop between the room and the outside does

not exceed a value of 4 Pa. (also for Oyster appliances if combustion air has not been suitably ducted outside). If necessary increase the

intake section of the air inlet, which must be made at oor level and always protected with a bird-proof outer protection grid and in such

a way that it cannot be obstructed by any object.

In order to fully enhance the sealed features and heating performance of this Oyster appliance, and thus to avoid tting a free air intake

in the room, it is recommended to connect the air required for combustion directly to the external air intake through 60 mm piping

with maximum length 3 linear metres, using the

suitable “j” 48/60 adapter supplied with the

appliance; each pipe elbow must be considered as

equivalent to one linear metre.

In the event a longer connection should be

required, further extend with an 80mm smooth

pipe. In any case do not exceed 8 linear metres

of ducting (also taking into account the elbows).

In sealed stoves the connection must be sealed in

order not to aect the overall sealed features of

the system.

For stoves installed in studio ats, bedrooms and

bathrooms (where allowed), it is mandatory to

connect the combustion air outside.
