2.4. CONNECTING THE EXTERNAL AIR INLET
The room in which the stove is installed MUST provide at least as much
airflow as is required for regular combustion of the appliance in the
room. This can be achieved via permanent apertures made in the walls
of the room to be ventilated, leading to the outside, or via individual or
grouped ventilation ducts.
To achieve this a through hole with a minimum free cross-section of
150 cm² must be drilled in the external wall near the stove. (12 cm
diameter or 10x10 cm square hole), protected by a grille on the inside
and on the outside.
The air inlet should also:
be directly connected to the installation setting
be protected with a grille, metal mesh or suitable protection,
provided it does not reduce the minimum cross-section.
be positioned in such a way that it cannot become obstructed
It is not obligatory to connect the air inlet directly to
the stove (direct connection to the outside) but the
aforementioned section must ensure that
approximately 50 m³/h of air is provided.
See standard UNI 10683.
2.5. CONNECTING THE SMOKE OUTLET PIPE
When making the hole for the smoke outlet pipe you must take note of
any flammable material. If the hole must pass through a wall made
from wood or thermolabile material THE FITTER MUST begin by using
the relevant wall connection minimum diameter 13 cm) and suitably
insulate the stove pipe crossing through it using appropriate insulating
materials (thickness of 1.3 - 5 with min. heat conductivity of 0.07
W/m°K).
This instruction is also relevant if the stove pipe must cross vertical or
horizontal sections close to the thermolabile wall (min. distance 20 cm).
Alternatively, we recommend the use of an insulated industrial pipe that
can also be used externally to prevent condensation.
The combustion chamber works under vacuum. The smoke duct
through which the smoke is discharged will be under vacuum when
connected to an efficient flue pipe, as specified.
