d) Liquidified petroleum gases are heavier than air and, as a
result, settle downwards. Rooms in which LPG tanks are
installedmustbefittedwithventilationopeningstotheoutside
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, ect.). 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°C.
InstallationofBuilt-inHobs
Thegashobis equipped with type X degree protectionagainst
overheating.Therefore, the appliance can be installed next to
cabinets, provided the height of the cabinet does not exceed
that of the hob.For proper installation of the hob, the following
guidlinesmustbefollowed:
a) If the cabinet(s) located next to the hob are higher than the
hob itself, the cabinet(s) must be installed at least 110 mm
fromthehobedge.
b) Hoodsmust beinstalledinaccordancewiththeinstructions

c) In the case of the 600 mm cooker hoods, besides following
the recommendations in point b), the cabinets should be
positioned next to the hood at a height of at least 540 mm
from the top since this will make it possible to install the lid
andmoveitcorrectly.Thecabinetshouldalwaysbeinstalled
at a height from the top which allows easy use of pots and
pansonthe cooker.
d) Should the hob be installed directly under a cupboard, the
latter should be at least 700 mm (millimetres) from the top,
