they do not come in touch with mobile
parts or they are not squeezed. Also be
careful when the hob is put together with
an oven.
Make sure that the gas
supply pressure of the
appliance obeys the
recommended values.
If the supplied pressure has not the
specified value, it is necessary to
assemble a proper pressure regulator in
compliance with the standard UNI EN 88.
For Liquid Gas (LPG) the use of pressure
regulator is allowed only if they are in
compliance with UNI EN 12864. The
adjustable connection is fixed to the
comprehensive ramp by means of a
threaded nut G 1/2". Screw the parts
without force, adjust the connection in
the necessary direction and tighten
everything.
