B）The room must also allow for the influx of the air needed for proper combustion. The flow of

air for combustion purposes must not be less than 2 m3/h per kW of installed capacity. The

supply of said air can be effected by means of direct influx from the outside through a duct with

a inner cross section of at least 100 cm2 which must not be able to be accidentally blocked.

Those appliances which are not fitted with a safety device to prevent the flame from

accidentally going out must have a ventilation opening twice the size otherwise required, i.e. a

minimum of 200 cm2 (Fig. A). Otherwise, the room can be vented indirectly though adjacent

rooms fitted with ventilation ducts to the outside as described above, as long as the adjacent

rooms are not shared areas, bedrooms or present the risk of fire (Fig. B).

C）Intensive and prolonged use of the appliance may necessitate supplemental ventilation,

e.g. opening a window or increasing the power of the air intake system (if present)

D) Liquefied petroleum gases are heavier than air and as a result, settle downwards. Rooms in

which LPG tanks are installed must be fitted with ventilation openings to the outside in order to

allow the gas to escape in the event of a leak. Therefore, LPG tanks, whether empty or

partially full, must not be installed or stored in rooms or spaces below ground level (cellars,

etc.). It is also a good idea to keep only the tank currently being used in the room, making sure

that it is not near sources of heat (ovens, fireplaces, stoves, etc.) that could raise the internal

temperature of the tank above 50
