Connection using a rigid pipe or
a flexible metal pipe
To ensure higher safety, it is recommended to carry out
the connection to the gas system using rigid pipes (ex.
copper) or using flexible stainless steel pipes, to avoid
any stress to the unit.
Gas feeding pipe fitting is Gc 1/2.
For this type of installation, connection to the gas supply
should be carried out using only and exclusively flexible
metallic tubes in conformity with rules in force.
Connection using flexible, non
metal pipe
When the connection can be easily inspected in its full
extent, there is the chance to use a flexible pipe
according to the rules in force.
The flexible pipe must be tightly fixed using clamps
according to the rules in force.
The flexible pipe should be made ready for use in such
a way that:
- nowhere it can reach overtemperature, other than
room temperature, higher than 30°C; if the flexible
pipe, to reach the cock, must run behind the range,
it must be installed as shown in Fig. 20;
- it is no longer than 1500 mm;
- it shows no throttles;
- it is not subject to traction or torsion;
- it doesn't get in touch with cutting edges or corners;
- it can be easily inspected in order to check its
condition.
The control of preservation of the flexible pipe consists
in checking that:
- it doesn't show cracks, cuts, marks of burnings both
on the end parts and on its full extent;
- the material is not hardened, but shows its normal
elasticity;
- the fastening clamps are not rusted;
- expiry term is not due (5 years).
IMPORTANT
Once installation is complete, check the perfect seal of
every pipe fitting, using a soapy solution, never a flame.

Gas connection must be carried out according to the
rules in force.
The manufacturing company release the unit, once
tested, adjusted for the kind of gas stated on the rating
plate located on the back of the range, next to
connection pipe. Be sure that you are going to connect
the unit to the same kind of gas written on the plate.
Otherwise, follow all the instructions of the paragraph
"REGULATION TO DIFFERENT KINDS OF GAS".
For best efficiency and lowest consumption, be sure that
manifold gas pressure respects the values in the table
of "Burners characteristics".
If gas pressure is different (or variable) from the proper
one, a suitable pressure regulator should be installed on
feeding pipe.
The use of pressure regulators for liquid gas (LPG) is
allowed provided they are modelled in conformity with the
rules in force
Gas connection
If one or more abnormalities are seen, do not repair the
pipe, but replace it.
To connect the range to LPG cylinder, use a flexible
pipe, introducing it into the cylinder holder through the
lower opening in the back and set it in position fastening
it with the two laces, as shown in Fig. 21
Attention: it should never touch the left side of the holder.
Use the proper holder bottom (A - Fig. 21) to avoid the
cylinder touch the floor.
