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 (UNI -
CIG 9891), not to cause 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 UNI 9891/
class 2 sub-class 1.
CONNECTION USING FLEXIBLE,
NON METAL PIPES
When the connection can be easily inspected in its full
extent, there is the chance to use a flexible pipe
according to the rules UNI-CIG 7140.
The flexible pipe must be tightly fixed using clamps
according to the rule UNI-CIG 7141.
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. 25;
-
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).
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 (UNI-CIG 7140) 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. 26.
Attention: it should never touch the left side of the
holder.
Use the proper holder bottom (A - Fig. 26) to avoid the
cylinder touch the floor.
IMPORTANT
Once installation is complete, check the perfect seal of
every pipe fitting, using a soapy solution, never a flame.
