QUALIFIED INSTALLER
(UNI CIG 7129/7131)
The appliances must be connected to the gas network with rigid or flexible metal
pipes (maximum length 2 meters) suitable for gas appliances. The connecting
pipes and their maximum lengths must meet current standards (UNI CIG 9891),
be replaced before the deadline (if specified on the pipe) and be connected to
the appliance by means of fittings:
A) Directly on the ISO R228 connection (seal with ISO R228 gasket), if the pipes
allow it, see figure 3
B.1) If the connection must be direct (right-left-down), the accessory must be
inserted (fig. 4a - fig. 4b).
B.2) Use the gasket (ISO R228) to seal between the tube and the ramp. 4a
B.3) The tapered fittings with the seal on the thread must be used for sealing on
the thread (ISO R7) (fig. 4b)
B.4) To improve the seal, it is possible to use a mastic suitable for GAS.
When the gas is taken from a cylinder, the appliance must be powered with a
pressure regulator compliant with the UNI-CIG 7432 standard:
- with continuous flexible stainless steel wall pipes according to UNI-CIG 9891, with
a maximum extension of 2 meters and sealing gaskets according to UNI 9264.
The gas taps fitted in your kitchen must work with liquid gas of controlled quality,
supplied at the proper nominal pressure. This pressure must be guaranteed by a
special certified pressure regulator. The use of gas coming from uncertified sour-
ces and/or the improper use of the GPL cylinder as well as the relative regulator,
can invalidate the product’s guarantee. It is especially necessary to avoid all the
situations that could pollute the gas with residues and impurities that, when in-
troduced into the gas circuit, can irreparably damage the control components
such as taps and thermostats. It is recommended to:
• use only GPL cylinders coming from official retailers and authorised by the
various manufacturers;
• use the cylinders until empty without inclining or overturning them;
• carry out regular cleaning of the filter at the pressure regulator inlet;
When the connection is made, it is recommended to check the connections’
seal with special foams (NO FLAMES).
Periodically check the gas connection pipe’s good condition and replace it
when there are signs of anomalies.
