The following instructions are provided for qualified installers
so that they may carry out installation, adjustment and
technical maintenance operations correctly and in compliance
with the applicable norms in force.
Important: Disconnect the appliance from the electrical
and gas supply before performing any maintenance or
repair. Maximum caution should be used should it be
necessary to keep the appliance connected to the electricity
supply.
The cooker has the following technical specifications:
- Cat. II2H3+
The dimensions of the appliance are given in the figure on
page 5, 'KNOW YOUR COOKER'. For trouble-free operation
of appliances installed in furniture cabinets, the minimum
distances shown in fig. 5 should be observed. Adjacent
surfaces and the wall at the rear should also be able to
withstand a temperature rise of 65 °C.
Prior to installing the cooker, the 99 - 155 mm high supporting
feet (provided) should be fitted into the holes to be underneath
the cooker (fig. 6). These feet are screw-adjustable and
whenever necessary should be used to make sure the cooker
is level.
Positioning
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 cooker should not be installed in a bed sitting room
with a volume of less than 20m3. If it is installed in a room of
volume less than 5m3 an air vent of effective area of 110cm2
is required, if it is installed in a room of
volume between 5m3 and 10m3 a supplementary airvent area
of 50cm2 is required, if the volume exceeds 11m3 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 when the volume is between 5m3
and 11m3.
b) During prolonged use of the appliance you may consider it
necessary to open a window to the outside to improve
ventilation.
c) If there are other fuel burning appliances in the same room,
B.S.5440 Part 2 Current Edition, should, be consulted to
determine the requisite air vent requirements.
INSTALLATION

(reserved for cooking appliances
Kitchen ventilation
The air flow into the room where the appliance is installed
must equal the quantity of air that is required for regular
combustion of the gas and for ventilating the same room.
Air must enter naturally through permanent apertures made
in the outside walls of the room or through single or
branching collective ventilation ducts in compliance with
the norms. The air must be taken directly from the outside,
from an area far from sources of pollution. The ventilation
aperture must have the following characteristics (fig. 8A):
• total free cross section of passage of at least 6cm2² for
every kW of rated heating capacity of the appliance, with
a minimum of 100cm2² (the heating capacity is indicated
on the rating plate);
• it must be made in such a way that the aperture, both on
the inside and outside of the wall, cannot be obstructed;
• it must be protected, e.g. with grates, wire mesh, etc. in
such a way that the above-mentioned free section is not
reduced;
• it must be situated as near to floor level as possible.

The air inflow may also be obtained from an adjoining room,
provided the latter is not a bedroom or a room where there
is a risk of fire, such as warehouses, garages, fuel stores,
etc. and is ventilated in compliance with the norms. The air
flow from the adjoining room to the one to be ventilated
may pass freely through permanent apertures with a cross
section at least equal to that indicated above. These
apertures may also be obtained by increasing the gap
between the door and the floor (fig. 8B). If an electric fan is
used for extracting the combustion products, the ventilation
aperture must be increased in relation to its maximum
performance. The electric fan should have a sufficient capacity
to guarantee an hourly exchange of air equal to 3 ÷ 5 times
the volume of the kitchen. Prolonged, intensive use of the
appliance may require extra ventilation, e.g. an open window
