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 a maximum length of 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. If a longer connection should be required, increase further with an 080 mm smooth pipe.
However, do not exceed 8 linear metres of ducting (considering the curves too). 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
BELOW
Windows, doors, smoke outlets, cavities, ....
1.5 m
HORIZONTALLY
Windows, doors, smoke outlets, cavities, ....
0.3 m

AT A DISTANCE
from smoke outlet
CONNECTION TO THE FLUE
The connection between the flue and the appliance must be via a smoke duct that complies with EN 1856-2. The connecting section must
extend no more than 4 m horizontally, with a minimum slope of 3% and with a maximum of 3 90° bends (accessible for inspection - do
not count the T fitting at the appliance outlet).
The diameter of the smoke duct must be equal to or greater than that of the outlet of the appliance (Ø 80 mm).

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 hoses made of fibre
cement or aluminium is forbidden. For direction changes, we always recommend the use of a T fitting
with an inspection cap
allowing easy access for cleaning the tubes. Always ensure that the inspection cap is put back in place and sealed hermetically with the
relevant seal intact after cleaning.
It is prohibited to connect more than one appliance to the same smoke duct, or the discharge from hoods above it. It is forbidden to extract
the combustion products directly through the wall, whether into indoor spaces or outdoors.
The smoke duct must be at a minimum distance of 400 mm from flammable or heat-sensitive structures.
