INSTALLATION
Gas connection
Caution!
The cooker should be connected to a
gas supply of the particular type of gas
that the appliance is manufactured to
function with. Information about the
type of gas that the cooker has been
adapted to by the factory is shown on
the data plate.
Fitting guidelines
A fitter should:
 have a gas fitter's authorisation,
 be acquainted with the information in-
cluded on the data plate of the cooker
about the type of gas to which the cooker
is adapted; the information should be
compared with gas supply conditions at
the place of installation,
 check:
- airing efficiency, that is efficiency of air
exchange in the rooms,
- tightness of gas fitting connections,
- effectiveness of all functional elements of
the cooker,
- if the electricity supply is adapted to func-
tion with a safety ground lead (zero).
 provide the user with a connection cer-
tificate and give him or her instructions
in cooker use.
Connection with a flexible steel hose
If the cooker is connected according to the
class 2 specifications, sub-class I, only flex-
ible metal hose can be used which meet
the valid national regulations. Gas feeding
connector must be G ½" threaded coupling.
Use only pipes and fittings that meet the
requirements of the valid standards. Maxi-
mum admissible length of the flexible hose
is 2000 mm.
Make sure the connection is not touching
any mobile elements which could damage
the hose.
Connection with a stable pipework
The cooker comes with a G ½" threaded
coupling.
The connection to gas supply must be done
in a manner that excludes stresses in any
point of the pipework or parts of the appliance.
Make sure you do not exceed the torque when
making the connection (maximum torque is
20 Nm). Otherwise, the connection may be
faulty or leaks may occur.
The gas hose should not touch metal ele-
ments of the cooker back shield.
Caution!
On completion of the cooker installa-
tion, the tightness of all connections
should be checked, e.g. applying
water with soap.
Do not use fire to check tightness.
