A) Gas connection
NL Cat: II 2EK3B/P
The gases used for the operation of cooking appliances may be grouped by
their characteristics into two types:
* G25.3 natural gas
* G20 natural gas
* G30 / G31 Butane/Propane
The fitting (fig. 9.2) is made up of:
A - Gas train terminal fitting (rh or lh)
B - Gasket
C - Conical connector
Use rigid or flexible connection
pipes which comply with applicable
regulations. If compression fittings
are used, tighten firmly using two
spanners (fig. 9.4). In particular,
make sure that:
* The flexible hose does not come into
contact with any parts of the cooker
with surface temperatures in excess of 70˚C;
* The flexible hose does not exceed 75 cm in length and does not come into
contact with sharp edges or corners;
* The hose is not under tension or twisted and is not kinked or too tightly bent;
* The connection with rigid metal pipes should not cause stresses to the
gas ramp.
* We advise replacing the gasket on the slightest sign of deformation or
imperfection.
* The hose can easily be inspected along its entire length to check its condition;
hoses should replaced after a maximum of three years.
