3.2 Checking the gas supply pressure
Before putting the oven into service, a check must be made to see whether it is suitable for the family and
type of gas available, as stated on the technical data plate. If it is not, see the paragraph “Conversion to
other types of gas”.
The gas supply pressure is measured, with the appliance in operation, using a pressure gauge for liquids
(for example a “ U “ type pressure gauge with a minimum 0.1 mbar resolution). To carry out this check,
access the gas valve by removing the right side panel from the oven; then, using flexible pipes, connect the
pressure gauge “ E “ to the pressure inlet “ V “ and pressure outlet “ X “ of the gas valve after removing
the relative fixing screws “ U “ and “ Z “ (see Fig 6).
Measure the incoming pressure: if this is not within the range of values shown in table 2, the oven must
under no circumstances be put into operation. The gas supply agency must be informed.
