Important!
Make sure that the gas supply
pressure of the appliance obeys the
recommended values. The adjustable
connection is fixed to the comprehensive ramp
by means of a threaded nut G 1/2". All the
components shown in the figure have already
been assembled in the factory. The appliance,
before leaving the factory, has been tested in
order to give you the best results.

Liquid gas
Use the rubber pipe holder for liquid gas. Al-
ways 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 tempera-
ture, 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 burn-
ings 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 repair
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 burn-
er.
3.
With a socket spanner 7 remove the injec-
tors and replace them with the ones which
are necessary for the type of gas you use
(see table in "Technical Information" chap-
ter).
4.
Assemble the parts, follow the same pro-
cedure 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 dif-
ferent from the necessary pressure, you must fit
an applicable pressure adjuster on the gas sup-
ply pipe.

1.
Light the burner.
2.
