2.3 - Heating

GAS MODEL
• Turn the gas supply on, operating the valve installed upstream
from the appliance.
• The gas cock's control knob "R" has 4 different positions:
OFF
PILOT ON
MAX. FLAME POWER
MIN FLAME POWER
• Press and turn knob "R" counter clockwise from the OFF
position to the PILOT ON position.
• At the same time, press the button of the piezoelectric lighter
"S" for a few sparks: it will ignite the pilot flame. Wait about
20 seconds from when the pilot flame lights and then release
the knob; the pilot burner flame should stay alight. If it doesn't
repeat the operation.
• You can see that the pilot burner is on through the inspection
window "T".
• To light the main burner, turn knob "R" round from the
PILOT ON position to the
MIN. FLAME POWER position.
• For indirect gas models
• When the pressure of the steam in the jacket is close to 0.45
bar (maximum value), the safety valve "L" starts venting;
reduce power according to cooking requirements by turning
knob "R".
Turning the main burner out
• When cooking is finished, turn knob "R" round to the PILOT
ON position to turn the main burner out; the pilot burner
stays alight ready to use the appliance.
• Turning the burners out when cooking is finished
- To turn the burner pilot out as well, turn knob "R" round to
the OFF position,
- close the on-off valve upstream from the appliance.
STEAM MODEL
• Open the on-off valve installed upstream from the appliance.
• Open the steam inlet valve "R" with the control lever, moving
it into the "OPEN" position (see user instruction sheet).
• Steam working pressure should range between 0.3 and 0.4 bar.
• If the maximum working pressure is reached (0.45 bar) the
safety relief valve "L" starts venting steam; adjust power by
turning knob "R".
• When cooking is finished, close the steam inlet valve by
turning knob "R" round to the "CLOSED" position.
• Close the steam on-off valve installed upstream from the
appliance.
ELECTRIC MODEL
• Turn the electricity on with the automatic switch installed
upstream from the appliance.
• Turn the energy regulating knob "R" round to position "I"
(where applicable, also turn knob "Y" of the electrical power
6
INSTRUCTIONS FOR USE
MAX. FLAME POWER or
shutter round to position I)
• When the green "S" coloured light turns on it means the
appliance is powered.
• When the yellow "W" coloured light turns on it means the
appliance is heating.
• When the pressure of the steam in the jacket is close to 0.45
bar (maximum value), shown on the manometer "H", the
appliance is ready to use.
• By turning the knob of regulator "R" round to the position
wanted you either reduce or increase heating power (where
applicable, by turning knob "Y" round into position "0" you
reduce the power of the appliance).
• When cooking is finished, turn the knob of the energy
regulator "R" found to position "0" and turn the automatic
switch off, installed upstream from the appliance.

3 - DRAINING THE TANK

CAUTION!
Both the liquid and the drainage tap are
extremely hot.

4 - SAFETY DEVICES

4.1 - Jacket

The indirectly heated pans are fitted with a set of safety
devices, consisting of:
• Manometer "H" which shows the pressure of the steam
inside the jacket;
• Vacuum and venting valve "I" that bleeds the air from inside
the jacket;
• Weight-loaded relief valve "L" calibrated for a maximum
pressure of 0.45 bar: it starts venting steam when pressure
inside the jacket is close to the above value.
• Screw cap "G" for filling the jacket with water.
During the very
effectiveness of the relief valve and then again at
least once every six months.
4.2 - Safety thermostat (standard in the
electrical versions, optional for gas)
• The appliance is fitted with a safety thermostat that trips,
stopping power to the heating elements (or burners if
applicable) if the water inside the jacket has dropped below
the minimum level.
• To restore operation after having added some decalcified
water to the jacket, you have to unscrew the protection cap
and press the red coloured button "U" on the pan's control
panel.
