Installation area and removal of combustion fumes
) The appliance must be installed and operated in suitable areas, and in compliance with
current laws.
The installation technician must observe current laws governing ventilation and removal of
combustion fumes.
The air required for combustion is 2m
3
/h per kW of power (gas) installed.
Installation area
In the room where the gas appliance is installed, there must be a sufficient natural air supply to allow
the gas to burn correctly.
The natural flow of air must take place through an opening made on an outside wall of the room and
having a working section of at least 100 cm
2
(A). In the case of appliances without safety valves, this
opening must have a minimum working section of 200 cm
2
(fig. 10).
This opening must be made in such a way that it cannot be obstructed from inside or outside. It should
be positioned near floor level, preferably on the side opposite the fume exhaust devices.
If it is not possible to make the necessary openings, the air can be supplied from an adjacent, suitably
ventilated room, as long as this room is not a bedroom, a dangerous area or a low-pressure area.
Removal of combustion fumes
Combustion fumes produced by gas appliances must be removed by means of a hood connected
directly either to an exhaust duct or to the outside (fig. 10).
If a hood cannot be installed, an electric extractor fan must be fitted to the outside wall or the window.
This electric extractor fan must have a sufficient capacity to guarantee a change of air of the kitchen of
at least 3-5 times its volume.

C: Hood for exhaust removal of combustion fumes
E: Electric extractor fan for removal of combustion fumes
Connection to gas supply
) Before installation, make sure the type and pressure of the local gas supply are compatible
with the cooktop settings. To do this, check the data on the appliance data plate on the
cooktop as well as on this handbook.
The gas connection must be carried out by a qualified technician in compliance with local current
regulations.
If using metal hoses, ensure these do not come into contact with any movable parts and are at no
point crushed.
Carry out the connection in such a way as does not cause any stress whatsoever on the appliance.
The gas supply connector is threaded G½”. ( fig. 14)
For ISO R7 connections, the gasket is not required.
For ISO R228 connections, the washer supplied must be fitted.
) After connection operations, check for leaks using a soapy solution.
Electrical connection
Before connecting the appliance to the electricity supply, check that the voltage corresponds to that on
the data plate and that the power supply cable is suitable for the appliance load also stated on the
data plate.
If the appliance is connected directly to the mains, fit an all-pole disconnect switch with minimum
contact gap of 3 mm, adequate for the appliance load and complying to regulations.
