If these conditions are maintained, the air flow can be supplied from a place nearby :
The place nearby must be directly ventilated;
Only devices connected to the ventilation pipes must be installed in the area to be ventilated;
The nearby place should not be a garage, barn or storage place where fuels or combustibles
are stored;
Due to the counter flow effect of the nearby area, it should be at an area of low pressure
compared to the area to be ventilated. (The counter flow in the area may arise due to another
device operating with no air inlets or the presence of another aspiration device or fireplace.);
!
The air flow from the place nearby to the installing area to be ventilated can be free due to
permanent spaces. The said spaces can be provided by keeping a wide space between door and
floor.

If air flow is insufficient, the combustion air may be supplied by an orifice from one or more rooms
nearby the installing room by air orifices as seen in the figure
1.2. Hermetic “C” Type Wall Hung Boiler Placement
BAYKAN 24-28-32 Hermetic Wall hung boilers are type C heat producers and they are not limited by
any regulations regarding the area of their installing.
The said devices can not in any case be installed in positions entertaining the risk of fire such as barns,
cellars, garages, unoccupied areas in buildings. It is forbidden.
Since the Hermetic devices supply the air for combustion from outdoor and not interior areas, there is no
obligation for an air orifice. There is no limitation of space considering the volume they are installed in.
