gas
Check that the type of nozzles used match manufactu-
rer's specifications.
Check that the output pressure regulator installed colla-
terally to the plant conforms to the specifications laid
down in paragraph "Checking input pressure" page 8
(see data plate or measure the pressure).
Checking the pilot light
When correctly adjusted, the pilot light flame will com-

roughly checked.
Running the appliance on other types
of gas
When changing to another type of gas, e.g. from natural
to LP, or to another gas group, consult the “TECHNICAL
DATA” table to determine the correct nozzles to use.
The nozzles for the main burners for different types of
gas, marked in 100ths of mm, are in a case supplied with
the appliance.
When the appliance has been transformed or adapted,

Replacing the main burner nozzle
(Fig. 1)
To change the nozzle (28), remove the air adjustment (27)
loosening the screw (33), unscrew it from the nozzle hol-
der using a 12 mm wrench and replace with a new one
(see “TECHNICAL DATA” table).
After fitting the nozzle, reset primary air distance “A”
(see “TECHNICAL DATA” table).
Adjusting the pilot burner (Fig. 1)
The pilot burner is readily accessible when the door is
opened.
Unscrew nut (34) and using a screwdriver adjust the by-
pass. For use with LPG, the adjusting screw must be ful-
ly screwed down. Tighten the nut, making sure the ga-
sket has been inserted.
