permanently ventilated rooms according to the British
Stancards Codes Of Practice: B.S. 6172 / B.S. 5440, Par.
2 and B.S. 6891 Current Editions. The following

a volume of less than 20m 3 . If it is installed in a room of
volume less than 5m 3 an air vent of effective area of
110cm 2 is required, if it is installed in a room of volume
between 5m 3 and 10m 3 an air vent of effective airvent of
50cm 2 is required, while if the volume exceeds 11m 3 no
airvent is required. However, if the room has a door or a
window which opens directly to the outside no air vent is
required even with the volume is between 5m
3 and 11m 3 .
b) Intensive or prolonged use of the appliance could mean
that extra ventilation is needed, such as the opening of
a window or a more powerful fan.
c) If there are other fuel burning appliances in the same
room, B.S. 5440 Part 2 Current Edition, should be
consulted to deter mine the requisite air vent
requirements.
Installation of built-in gas hobs
The gas hobs are prepared with protection degree against
excessive heating of type X, the appliance can therefore
be installed next to cabinets, provided the height does not
exceed that of the hob. For a correct installation of the
cooking hob the following precautions must be followed:
a) The hob may be located in a kitchen, a kitchen/diner or
bed sitting room, but not in a bathroom or shower room.
b) The furniture standing next to the unit, that is higher than
the worktops, must be placed at least 110mm from the
edge of the board.
c) The minimum distance combustible material can be
fitted above the hob in line with the edges of the hob is
420mm. If is fitted below 420mm a space of 50mm
must be allowed from the edges of the hob. The
