WARNING! MODELS P110G! The valve adjustment screws must not
be tampered with: they are calibrated and sealed in the factory. It is
necessary to intervene on the pressure regulator for the gas valve
(fig.17 item C) , to guarantee the correct thermal capacity (see
technical data TAB.1) on the P150G only
3.1.2 CHECKING THERMAL CAPACITY WITH LP GAS
3.1.2.1 MODELS P110G
The rated thermal capacity is achieved with the nozzle indicated in the
table (see technical data TAB.1), the air feed opening (fig.21 item D) must
be at a distance X= see technical data TAB.1.
Operation depends on the inflow pressure available (see technical data
TAB.1):
Should the pressure be outside the values indicated above, advise those
responsible for the system and do not start up the oven until the cause has
been traced and eliminated.
3.1.2.2 MODELS P150G
Rated thermal capacity is only achieved by setting the gas valve pressure
regulator (fig.17 item C) as shown in 3.1.6, so as to guarantee valve outlet
pressure (fig.17 item B) the same as the one shown in the technical details
TAB.1; the air feed opening (fig.21 item D) must be at a distance X= see
technical data TAB.1, the nozzle needs to be the one listed in the nozzle
table (see technical data TAB.1).
Operation depends on the inflow pressure available (see technical data
TAB.1):
Should the pressure be outside the values indicated above, advise those
responsible for the system and do not start up the oven until the cause has
been traced and eliminated.
3.1.3 CHECKING THE THERMAL CAPACITY NATURAL GAS
3.1.3.1 MODELS P110G
The rated thermal capacity is achieved with the nozzle indicated in the
table (see technical data TAB.1), the air feed opening (fig.21 item D) must
be at a distance X= see technical data TAB.1.
Operation depends on the inflow pressure available (see technical data
TAB.1).
Should the pressure be outside the values indicated above, advise the gas
supply company and do not start up the oven until the cause has been
traced and eliminated.
NOTE! Should an additional test be required for the thermal capacity,
it can be performed using the volumetric method.

3.1.4 CHECKING INLET PRESSURE.
The inlet pressure must be measured with a water manometer (for example
a U manometer, with a minimum resolution of 0.1 bar).
To do this, proceed as follows:
-
Remove the right hand side panel (fig.20 item C).
- Loosen the seal screw inside the valve (fig.17 item A)
- Connect the U manometer to the pressure takeoff.
- Turn the oven on as described in the instructions.
- Measure the pressure.
- Turn the appliance of as indicated in the instructions.
- Remove the manometer.
-
Tighten the seal screw again (fig.17 item A).
- Replace the right hand side panel (fig.20 item C).
NOTE! The pressure must be read with all the chambers operating.
3.1.5 CHECKING THE PRIMARY AIR
The air feed opening (fig.21 item D) must be at a distance
X= see technical data TAB.1.
3.1.6 VALVE OUTLET PRESSURE CONTROL
To regulate the valve outlet pressure to the setting listed in the technical
details TAB.1, it is necessary to:
-
Remove the right hand side panel (fig.20 item C).
- Loosen the seal screw external the valve (fig.17 item B)
- Connect the U manometer to the pressure takeoff.
- Turn the oven on as described in the instructions.
- Measure the pressure.
-
Loosen the cap of the gas valve pressure regulator (fig.17 item D).
- Use the screw (fig.17 item C) on the pressure regulator to set the
pressure as listed in the technical details TAB.1.
- Turn the appliance of as indicated in the instructions.
- Remove the manometer.
-
Tighten the seal screw again (fig.17 item B).
- Tighten the cap of the gas valve pressure regulator (fig.17 item D).
- Replace the right hand side panel (fig.20 item C).
NOTE! The pressure must be read with all the chambers operating.
3.2
STARTING UP THE BAKING CHAMBER
WARNING! The glass and the door will heat up when the oven is
working. Do not touch them, or you will burn yourself.
Two control panels are fitted on the front right hand side of the baking
chamber, as shown in figure 18.
1.
Main switch (ON/OFF)
2. Safety thermostat (Reset)
3. Temperature regulator (+up/-down)
4. Set temperature display (Set Point)
5. Internal temperature display
6. Baking chamber light on/off button (light)
7. Reset button
8. Burner warning light
9. Baking chamber on/off button
NOTE! The electronic controls allow more precise and rapid
regulation of the oven. However, they are by nature more delicate
than traditional ones.
To ensure that they remain in a proper state of operation it is
recommended that the buttons on the electronic control panel be
activated by pressing lightly with one finger, avoiding excessive
pressure and impact.
To turn the baking chamber on, proceed as follows:
a)
Turn the main switch (fig.18 item 1) on the top control panel to ON.
Both the switch itself and the electronic panel below it will light up.
b) Set the required cooking temperature using the buttons provided
(fig.18 item.3). The temperature will appear on the luminous display
on the right side (fig.18 item 4).
c) Supply power to the chamber using the ON/OFF button (fig.18 item
9): a red LED will light up in the top right hand corner.
d) When the electrode lighting the burner has reached the correct
temperature, the red led indicating burner in use (fig. 18 item 8) comes
on and after a few seconds the burner starts up.
If the oven does not start up 15\20 seconds after the "burner in use"
indicator light comes on (fig.18 item 8), the luminous indicator on the
reset button will light up (fig.18 item 7) indicating that the burner is
blocked.
This safety system intervenes to detect an absence of flame by means of an
ionised probe located over the burner: if this probes is not submerged by
the flame for an interval of five seconds, the gas supply is immediately cut
off.
Check that gas is reaching the burner (i.e. check that the gas supply tap is
open), wait 20 seconds and then reset the burner by pressing the reset
button (fig.18 item 7).
WARNING! If the indicator light does not turn off this means that the
burner is still blocked, and therefore that a malfunction has occurred.
In this case, contact the technical service department.
NOTE! When the temperature inside the baking chamber (fig.18 item
5) reaches the set temperature (fig.18 item 4), the burner switches off.
When the temperature inside the baking chamber drops below the set
value (fig.18 item 5), the burner will light up again automatically.
e) The maximum temperature that can be set (fig. 18 item 4) is 842 F
(450°C).
If the internal temperature exceeds this maximum limit due to a fault,
the safety thermostat automatically will trigger (fig.18 item 2)
stopping oven operation and turning off the burner. All the LED’s on
the lower control panel will start flashing, signalling alarm.
WARNING! Disconnect the power supply and the gas supply, leave
the appliance to cool down, and call a specialised installation
technician with the necessary qualifications to identify the cause of
overheating. Eliminate the problem, check that none of the
components in the appliance have been damaged and replace if
necessary. Always replace the burner/s, as any deformation due to
