Regulating the flame
Due to the different characteristics of the gases used, flames with too much or too little air
may be obtained.In this case,regulate the flame as follows (fig. 5):
• loosen screw “C” and turn ring nut “D” to position N for methane or natural gas and
position GPL for liquid propane, ensuring that the mobile index on the ring nut
corresponds with the fixed index on the burner, thereby obtaining the correct flame
(fig. 6)
Minimum regulation
The oven thermostat is equipped with a minimum bypass and it is necessary to alter
regulation if gas type is changed, in the following manner:
• Remove control knob A;
• Remove the two ring nuts on panel B by unscrewing in an anti-clockwise direction.
• Remove control panel C;
• Remove the oven bottom plate (fig. 4);
• Turn on the oven at the highest temperature for at least 10/15 minutes.
• Turn the indexed thermostat knob to 150°C, regulate the by-pass to minimum until a
reduced but stable flame is obtained. This operation should be performed with the
oven door closed.
• Use a screwdriver on the bypass screws. It is sufficient to unscrew the bypass several
turns to regulate the minimum, passing from liquid gas to methane (fig, 7).
• IMPORTANT: after regulating the burner, check the flame remains at the minimum,
by opening and closing the oven door. If the flame goes out, adapt bypass regulation.
• For operation with G30/G31 , the bypass regulation screw must be screwed tight.
On completing regulation, indicate the gas setting on the new plaque.
