Operational Check - Moretti Forni P110GC/A3 Manual De Instrucciones

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
METHANE GAS (G20-G25)
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.
3.2 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).
THERMAL CAPACITY
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
WITH 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 450°C
(842°F).
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
overheating mean that any further use will cause a fire hazard; always
replace the thermocouple (item 32 Plate A).
To restore the oven to normal operation, unscrew the safety thermostat
cap (fig.18 item 2) and press the button underneath it.
The button inside will reset the thermostat, the lower panel will stop
flashing and the oven will start up normally.
Replace the protection cap (fig. 18 item 2) over the safety thermostat to
avoid it being damaged and compromising oven operation.
f) The "Light" button (fig.18 item 6) is used to turn the lighting inside
the baking chamber on and off.
g) To turn the oven off, merely press the main switch (fig.18 item 1).
When the oven is turned on again, the control panel will be in the state
as when it was last turned off.
3.3 STARTING UP THE LEAVENING COMPARTMENT
The control panel is located on the front right hand side of the leavening
compartment, as shown in figure 19.
1. Indicator light (ON/OFF).
2. On/off switch for inside light.
3. Start-up and regulation thermostat.
To start the leavening compartment, proceed as follows:
a) Turn the leavening compartment on by turning the thermostat (fig.19
item 3), the indicator light will come on (fig.19 item 1).
b) Set the temperature required, up to a maximum of 65°C (149°F).
c) To turn the leavening compartment off, turn the thermostat (fig.19
item 3) back to zero.
3.4

OPERATIONAL CHECK

Once the baking chambers and the leavening compartment are operational,
according to 3.2 and 3.3, check that the appliance functions.
Check that the exhaust works correctly.
Check for perfect start-up and the stability of the burner flame.
3.5 TRANSFORMATION AND / OR ADAPTATION
All operations must be carried out by specialised and duly licensed
technicians.
Before connecting to the new gas supply, check that the appliance
supply pressure is the one indicated in Tab.1, and that this pressure is
guaranteed to remain unchanged on a long term basis.
If the supply pressure is outside the values indicated, advise the gas
supply company and do not start up the appliance until the cause has
been identified and eliminated.
To adapt to another type of gas, (for instance from methane to LPG), it is
necessary to replace the nozzle. For this, please consult the "Technical
data TAB.1".
The nozzles for different types of gas are supplied in a small bag together
with the oven.
For transformation, close the gas tap, raise the front protection (fig.20 item
A) (for the P110G A it will also be necessary to remove the cover fig.20
item B), remove the seal on the nozzle, unscrew it from the burner (fig.21
item C) and replace it with the correct one, sealing the nozzle again with a
drop of red paint.
Remove the seal from the primary air feed opening, adjust the feed
opening (fig.21 item D) so that it is at a distance X= see technical data
TAB.1.
Seal the primary air feed opening again with a drop of red paint.
WARNING! If a transformation or adaptation has been made
according to 3.5, attach the rating plate with corrected data in position
A on top of the previous one (fig.3).
