N.B.: It is important that the grid communicates with the external
air vent without connection via pipes.
If it is not possible to realise the air vent in the wall behind the
fireplace heating system, make the hole in a perimeter wall where the
fireplace heating system is installed.
If it not possible to realise the external air vent in the same room
where the fireplace heating system is installed, this hole can be made
in an adjoining room as long as this room communicates
permanently, by means of a transit hole (20cm minimum diameter).
The UNI 10683 Standard PROHIBITS the withdrawal of
combustion air from garages, combustible material warehouses,
or from activities where there is a fire hazard.
If there are other heating or suction appliances in the room, air
vents must guarantee an air volume necessary for the proper
functioning of all devices.
Only sealed appliances (e.g. C type gas appliances, according to
the UNI 7129 Standard) or appliances that do not cause a lower
pressure compared with the external environment can pre-exist
or be installed in the place where the fireplace heating system
must be installed.
Extractor fans can cause functioning problems to the thermo stove when
they are installed in the same room or space where the fireplace heating
system is found.
