Installation Instructions for Built-In
The following instructions are intended for the installer so that the installation and maintenance
procedures may be followed in the most professional and expert manner possible.
Positioning
This appliance may only be installed and operated in permanently ventilated rooms in
compliance with provisions laid down by current regulations and standards. The following
requirement must be observed:
A）The room must be fitted with a ventilation system which vents smoke and gases from
combustion to outside. This is 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. Directly to the Outside
(exclusively for cooking appliances)
7
B）The room must also allow for the influx of the air needed for proper combustion. The flow of
C）Intensive and prolonged use of the appliance may necessitate supplemental ventilation,
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).
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 500C.
8
Installation of Built-In cooktops
The appliance can be installed next to furniture units which are no taller than the top of the
cooker. The wall in direct contact with the back panel of the cooker must be made of
non-flammable material. During operation the back panel of the cooker could reach a
temperature of 500C above room temperature. For proper installation of the cooker, the
following precautions must be taken:
• Kitchen cabinets adjacent to the appliance and taller than the top of the cooktop must be at
least 200 mm from the edge of the cooktop.
• Hoods must be installed according to their relative installation instruction manuals and at a
minimum distance of 650 mm from the cooktop.
• Place the wall cabinets adjacent to the hood at a minimum height of 420 mm from the
cooktop (see figure C).
If the cooktop is installed beneath a wall cabinet, the latter must be situated at a minimum of
720mm above the cooktop.
.
