pressure of the appliance obeys the
recommended values. The adjustable
connection is fixed to the comprehensive

Liquid gas
Use the rubber pipe holder for liquid gas.
Always engage the gasket. Then continue
with the gas connection.
The flexible pipe is prepared for apply
when:
– it can not get hot more than room tem-
perature, higher than 30°C;
– it is no longer than 1500 mm;
– it shows no throttles;
– it is not subject to traction or torsion;
– it does not get in touch with cutting
edges or corners;
– it can be easily examined in order to
make sure its condition.
The control of preservation of the flexible
pipe consists in checking that:
– it does not show cracks, cuts, marks of
burnings on the two ends and on its full
length;
– the material is not hardened, but shows
its correct elasticity;
– the fastening clamps are not rusted;
– expired term is not due.
If one or more defects are visible, do not re-
pair the pipe, but replace it.
Important! When installation is complete,
make sure that the seal of each pipe fitting
is correct. Use a soapy solution, not a
flame!
Injectors replacement
1. Remove the pan supports.
2. Remove the caps and crowns of the
burner.
3. With a socket spanner 7 remove the in-
jectors and replace them with the ones
which are necessary for the type of gas
you use (see table in "Technical Infor-
mation" chapter).
4. Assemble the parts, follow the same
procedure backwards.
5. Replace the rating plate (it is near the
gas supply pipe) with the one for the
new type of gas supply. You can find
this plate in the package supplied with
the appliance.
If the supply gas pressure is changeable or
different from the necessary pressure, you
must fit an applicable pressure adjuster on
the gas supply pipe.

1. Light the burner.
2. Turn the knob on the minimum posi-
tion.
3. Remove the knob.
