CONNECTION TO THE COMBURENT AIR INLET
PIPE (1)
Pipes and unions with suitable gaskets must always
be used, to guarantee a hermetic seal.
Products built with Oyster technology, thanks to a perfectly sealed
frame, do not consume oxygen by taking all the air from the
environment outside so therefore can be placed inside every home
properly insulated and within passive houses.
In order to satisfy these requirements, the connection pipe, with a
diameter of 80 mm, for the comburent air inlet
(1)
must be
connected outside the building.
The air intake must also:
be protected by a grill, made of metallic anti-insect mesh or a
suitable protection as long as it does not reduce the minimum
section.
be installed so as to avoid obstruction
the maximum permitted length for the duct is 6 m with two 90°
curves
The stove must be connected to the external air
intakes with pipes and unions that guarantee a
hermetic seal to fulfil the requirements of an airtight
stove (OYSTER technology).
2.5.
CONNECTION OF SMOKE DISCHARGE PIPE (2)
When making the hole for the passage of the smoke discharge pipe, it
is necessary to take into account the possible presence of flammable
materials. If the hole will be going through a wall made of wood or any
other material which is sensitive to heat, the
INSTALLER MUST
first
of all use the special wall union (diam.13cm 13cm minimum) and
properly insulate the pipe of the stove that passes through it, using
adequate insulation materials (thickness 1.35cm with minimum thermal
conductivity of 0.07 W/m°K).
The same is true if the stove pipe must run through vertical or
horizontal stretches passing in proximity (min.20cm) to the heat-
sensitive wall
As an alternative we recommend the use of insulated pipe, which can
also be used on the outside to avoid condensation.
The combustion chamber works in low pressure. The smoke duct for
the discharge of fumes will also be under low pressure when connected
to an efficient flue pipe as directed.
