3.3.1 TRANSFORMATION AND / OR ADAPTATION
To adapt to another type of gas, (for instance from methane to LPG),
it is necessary to replace the two nozzles. 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, proceed as follows:
-Turn the gas supply tap off.
-Remove the bottom rear panel.
-Remove the seals on the primary air bushes (see fig.14)
-Move the two bushes to access the nozzles.
-Remove the seals on the nozzles.
-Take the nozzles out.
-Replace the nozzles with the ones suitable for the new gas supply
(See Tab.1).
-Replace the seals on the nozzles using a drop of red paint.
-Return the bush to its correct position (see fig.14) and tighten
the lock screw.
-Replace the seals on the bushes using a drop of red paint.
-Calibrate the pressure switch for the new gas supply (See
Tab.1).
-Using the pressure connector on the gas valve, check that the
pressure upstream of the oven is the one indicated in the table
(See Tab.1).
-Check that there are no gas leaks.
WARNING! If a transformation has been carried out as
described in point 3.3.2., affix the new rating plate with the
correct data (see fig.3).
WARNING! Use LOCTITE 577 thread sealant only
3.4 CHECKING GAS
CALIBRATION
Check that the value set corresponds to the one indicated in the table
(See Tab.1).
3.5 STOPPING
- Turn the oven main switches to "off".
- Disconnect the power supply by turning off the main power
switches outside the oven.
- Turn off the gas tap
WARNINGS FOR START-UP OF THE APPLIANCE:
Initial start-up of the oven must be carried out by qualified staff, in
particular those from the MANUFACTURER Authorised Service
Centres.
Transformation of the gas supply from one family (methane, LPG) to
another must be carried out by qualified staff only. The technician
carrying out the operation must check:
A) that the rated values correspond to those of the power supply
network (electric, water, gas).
B) that the fume extractor pipe is fully operational.
C) that air infeed and fume evacuation take place properly in
accordance with current regulations.
D) that the gas circuit is properly sealed, using soapy water (not
using an open flame).
4 STARTING UP
WARNING!:
- The oven must always be under surveillance when in operation.
- During operation the oven surfaces, and in particular the glass,
become hot, so that care must be taken not to touch them so as to
prevent scalding.
- When opening the door make sure you stand at a safe distance
from any hot steam that may come out of the baking chamber.
- Never allow unauthorised persons to approach the oven.
- Maintenance operations must be carried out on the oven at
least once a year. In this regard we recommend you stipulate a
service contract.
- The oven has been designed to cook pastry products and similar
ones
- There is a safety handle on the inside of the door, to be used in
case of accidental closure of the door with somebody inside the
baking chamber. To open the door from the inside, turn the
safety handle clockwise.
4.1 STARTING UP THE OVEN
A control panel is fitted on the front right hand side of the baking
chamber, as illustrated (See Fig.12):
1) Main switch (ON/OFF)
PRESSURE SWITCH
2) Safety thermostat (Reset)
3) Temperature regulator (+ up / -down).
4) Set temperature display (Set point C)
5) Internal temperature display.
6) Baking chamber start/stop button (burner).
7) Start/stop timer button and set time display (Timer).
8) Baking chamber light on/off button (light)
9) Red fan alarm warning light (Fan Alarm).
10) Steam button.
11) Burner in use indicator light .
12) Reset button.
13) Red temperature alarm light (Security Alarm).
14) No gas supply to oven indicator.
15) Rotating carriage start / stop switch.
16) Vapour extractor operating switches.
NOTE!: The electronic control allows more precise and rapid
regulation of the oven. However, it is by nature more delicate than
traditional ones. To ensure that it remains 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) Close the oven door using the handle provided.
b) Turn the main switch (fig.12 item 1) on the top control panel to
ON. Both the switch itself and the electronic panel below it will light
up.
c) Set the required cooking temperature using the buttons provided
(fig.12 item 3). The value will be shown on the lower luminous
display (fig.12 item 4).
d) Supply power to the chamber using the ON/OFF button (fig.12
item 6): a red LED will light up in the top right hand corner.
e) Press the start / stop carriage switch (Fig.12 item 15).
f) When the electrodes lighting the burner have reached the correct
temperature, the red burner indicator light will come on (fig.12 item
11) and after a few seconds the burner will start up.
If the oven does not start up 15\20 seconds after the "burner in use"
indicator light comes on (fig.12 item 11), the luminous indicator on
the reset button will light up (fig.12 item 12) 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.12 item 12): the indicator light will turn on
(Fig.12 item 14) if there is no gas.
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.12
item 5) reaches the set temperature (fig.12 item 4), the burner
switches off.
When the temperature inside the baking chamber drops below
the set value (fig.12 item 5), the burner will light up again
automatically.
g) The maximum temperature that can be set (fig.12 item 4) is
270°C.
Should this maximum temperature be exceeded at any time due to a
fault, the manually reset safety thermostat (fig.12 item 2) will trigger,
stopping operation of the oven and turning off the burner.
WARNING! Disconnect the power and gas supply, allow the
appliance to cool down, and call a specialist technician with the
necessary professional qualifications to identify the cause of
overheating, eliminate that cause, check that none of the
components in the appliance have been damaged, and replace
them if necessary.
To restore the oven to normal operation, unscrew the safety
temperature thermostat cap (fig. 12 item 2) and press the button
beneath it, then fit the cap again to prevent deterioration of the
thermostat, as this might compromise proper operation of the oven.
The indicator light (fig.12 item 13) will start to flash to signal an
alarm. Call the service department.
h) The "Light" button (fig.12 item 8) is used to turn the lighting
inside the baking chamber on and off.
