Technical Dept. - All rights reserved - Reproduction is prohibited
In order to fully enhance the sealed features and heating performance of this Oyster appliance, and thus to avoid fitting a free air intake
in the room, it is recommended to connect the air required for combustion directly to the external air intake through 060 mm piping with
maximum length 3 linear metres, using the suitable “j” 048/60 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 affect the overall sealed features of the system.
For stoves installed in studio flats, bedrooms and bathrooms (where allowed), it is mandatory to connect the combustion air outside.
DISTANCE (metres) The air inlet must be at a distance of:
1.5 m UNDER Windows, doors, smoke outlets, cavities, ....
1.5 m HORIZONTALLY Windows, doors, smoke outlets, cavities, ....
0.3 m ABOVE Windows, doors, smoke outlets, cavities, ....
1.5 m AWAY from smoke outlet
CONNECTION TO FLUE
The connection between the flue and the appliance must be via a smoke duct that conforms with EN 1856-2. The connecting section
must extend no more than 4 m horizontally, with a maximum incline of 3% and containing a maximum of 3 90% bends (accessible for
inspection - do not count the T joint at the appliance outlet).
The diameter of the smoke duct must be equal to or greater than that of the appliance outlet (Ø 80 mm).

4 metres
Use smoke ducts with a diameter of 80mm or 100mm depending on the type of system, with silicone gaskets or similar gaskets that can
withstand the high operating temperatures of the appliance (min. T200 class P1). The use of flexible metal tubes in fibre cement
or aluminium is prohibited. For direction changes, we always recommend the use of a T joint with an inspection cap allowing
easy access for cleaning the tubes. Always ensure that the inspection cap is replaced and hermetically sealed with the seal in tact after
cleaning.
It is prohibited to connect more than one appliance to the same smoke duct, or the discharge from overhead cowling. It is prohibited to
extract the products of combustion directly through the wall, whether into indoor spaces or outdoors.
The smoke duct must be a minimum distance of 400 mm from flammable or heat-sensitive structures.
