IMPORTANT:
Never turn union C using force without first slackening nut A.
Gasket F (Fig. 5.1) guarantees the seal of the gas connection.
Replace it whenever it is even slightly deformed or imperfect.
If using flexible metal pipes, make sure they are not squashed, and do not come into
contact with moving parts.
Any connection to fixed metal pipes must be done in such a way so as not to place
undue stress on the hob chassis.
Any flexible pipes must be so installed as to be easily inspected along their whole
length. They must be changed before the expiry date (printed on the pipe itself) and
not exceed 2 metres in length.
After connecting to the gas mains, check that the couplings are correctly sealed, using
soapy solution, but never a naked flame.
