Important: the appliance should be disconnected from the mains electricity supply before any adjustment, maintenance, etc. is carried out. Maximum caution should be used should it be necessary to keep the appliance connected to the electricity supply.
The cookers have the following technical specifications:
Category: II 2H3+ Class: 1 Type: Y
The dimensions of the appliance are given in the figure on page 2.

Positioning
This appliance may only be installed and operated in permanently ventilated rooms in compliance with current standards. The following requirements must be observed:
•The appliance must discharge combustion products into a special hood, which must be connected to a chimney, flue pipe or directly to the outside (fig.6).
•If it is impossible to fit a hood, the use of an electric fan is permitted, either installed on a window or on an external wall, which must be switched on at the same time as the appliance.
In a chimney stack or branched flue | Directly to the outside |
(exclusively 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 be taken in naturally through permanent apertures made in the outside walls of the room or through single or branching collective ventilation ducts in compliance with current standards and regulations.
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.7A):
•total free cross section of passage of at least 6 cm² for every kW of rated heating capacity of the appliance, with a minimum of 100 cm² (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.

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 current standards and regulations.
Air from the adjoining room to the one to be ventilated may be made to 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.7B).
