6 INSTALLATION INSTRUCTIONS FOR BUILT-IN-HOBS

The following instructions are directed at the qualified installer so that the installation and
maintenance procedures may be followed in the most professional and expert manner possible.
Important: Unplug the electrical connection before performing any maintenance or
regulation upkeep work.
Positioning for gas hob
Important: this unit may be installed and used only in permanently ventilated rooms according to
the British Standards Codes Of Practice: B.S. 6172 / B.S. 5440, Par. 2 and B.S. 6891 Current
Editions.
The following requirements must be observed:
a) The room must be fitted with a ventilation system which vents smoke and gases from
combustion to the outside. This must be done by means of a hood or electric ventilator that
turns on automatically each time the hood is operated.
In a chimney stack or branched flue.
(exclusively for cooking appliances)
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 100cm² 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. 3). Otherwise, the room can be vented indirectly through 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. 4).

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) Liquidified 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,
