VERSIONS WITH GAS SYSTEM
GAS SYSTEM WITH MANUAL LIGHTING:
Turn the main switch to position 2 and wait until
the machine reaches working pressure. To light
the burner, press the gas push-button (n°1)
and keep it pressed and light the burner with a
match. Release the gas push-button after about
8/10 seconds. Use the “minimum fl ame” (n°2)
regulation screw to obtain the required fl ame
height (1/1.5 cm. high), turning it clockwise to
increase the fl ame and counterclockwise to re-
duce it. At this point remove the protection cowl
(det. A) after having slackened the “knurled” nut
(det.B); use the regulation screw (det. C) until the
required pressure is reached (clockwise for an
increase in pressure). To increase the gas fl ow,
turn the gas jet ring-nut (det.D) in a clock-wise
direction. Greater combustion (blue fl ame) may
be obtained by increasing the air fl ow through
the slot in the sleeve (det.E). On the other hand
lesser combustion (red fl ame) is obtained by
reducing the air fl ow.
GAS SYSTEM WITH ELECTRICAL LIGHT-
ING:
Turn the main switch to position 2 and wait until
the machine reaches working pressure. To light
the burner, press the gas push-button and keep it
pressed; at the same time intermittently press the
spark generator’s electric ignition push-button.
Release the gas push-button after about 8/10
seconds. Use the “minimum fl ame” regulation
screw to reduce the fl ame to the required mini-
mum (1/1.5 cm. high), turning it in a clockwise
direction. At this point use a 4 mm. Allen key on
the other regulation screw, turning it counter-
clockwise until the required pressure is obtained.
To increase the gas fl ow, turn the gas jet ring-nut
in a clockwise direction. Greater combustion
(blue fl ame) may be obtained by in-creasing
the air fl ow through the slot in the sleeve. On
the other hand lesser combustion (red fl ame) is
obtained by reducing the air fl ow.
