INSTALLATION
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+
Class 1 Class 2

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
•it must be situated as near to floor level as possible.

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.

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
