6. GAS CONNECTION

6.1 WARNINGS
• Make sure the appliance is set up for the type of gas with
which it will be supplied.
• The gas inlet connector is yellow in colour.
• Before installing consult your local gas utility company to check
the compatibility between the available supply and the
consumption of the appliance.
• Before hooking up the appliance to the gas pipeline remove the
plastic protective plug from the gas connector.
• Fit a rapid gas shut-off cock upline from the appliance in an
easily accessible position.
• On completion of installation, use soapy water to check gas
connections for leaks.
• It is not possible to adjust the combustion air ventilation
capacity.
• If the appliance is hooked up to a supply with a different gas type
with respect to the factory setting, after making the necessary
changes check that it is working correctly (see heading 8

"Operation Check").

6.2 NOMINAL HEAT OUTPUT

For data concerning the nominal heat output refer to "Technical
Data" in Table 1.
This parameter is determined by the pressure of the gas supply
and the diameter of the gas valve diaphragm (nozzle).
The appliance nominal heat output must always be checked (by
the authorised installer or by the gas utility company), both in the
case of new installations or following maintenance work.
It is strictly prohibited to make changes to the nominal heat
output.
6.3 CHECKING THE SUPPLY PRESSURE (Fig. 2a)
The gas supply pressure must be measured upline from the gas
shut-off cock with the appliance operating, using a pressure
gauge with minimum resolution of 0.1 mbar and proceeding as
outlined below:
1) Remove the left hand side panel to gain access to the gas
valve;
2) Loosen sealing screw "C" from the gas valve pressure test
point and connect the pressure gauge hose in its place;
3) Open the gas shut-off cock;
4) Start a mixed cooking cycle (see "Instructions for use") in
such a way that all the burners can be lit;
5) Check that the pressure reading is within the values given in
the following table:
GAS TYPE
Nom.
NATURAL
7"wc (17,4mbar)
PROPANE 11"wc (27,4mbar)
If the values are not within the values shown in the table the
appliance will not function.
In this case inform your gas utility company of the problem;
6) Once you have measured the supply pressure stop the cooking
cycle and close the gas shut-off cock.
7) Disconnect the pressure gauge and carefully refit and tighten
sealing screw "C";
8) Refit the previously removed side panel.
PRESSURE (MBAR)

7. SAFETY DEVICES

The appliance is fitted with the following safety devices:
- Fuses (see electrical circuit diagram) located behind the control
panel.
To change a fuse unscrew and remove the retainer cap and
replace the blown fuse with an identically rated component; the
fuse rating value is specified on the relative dataplate.
- Oven chamber safety thermostat with manual reset, located
behind the control panel; when this device trips, convection
heating power is disconnected.
Notice: CONTACT YOUR AUTHORIZED SERVICE COMPANY
TO PERFORM MANINTENANCE AND REPAIRS.
- Automatic reset thermal protection inside the cavity fan
motor: this device trips in the event of overheating of the cavity
fan motor; this cut-out protects the appliance by disconnecting
the power supply to the main PC board and an error message is
display EFUN.
8. OPERATION CHECK
- Switch on the appliance in accordance with the following
section "Instructions for use".
- With the aid of the Instruction Booklet, explain operation,
routine maintenance, and cleaning to the user.
Important:
- Exercise due care since certain areas of the oven exterior
become hot during use.
- Do not cover the exhaust outlets on top of the appliance.

9. SERVICING

All components requiring routine maintenance may be easily
reached by opening the control panel, removing the left side
panel, or removing the rear panel.
Danger: Live voltage is present with panels removed and unit
switch on. Exercise extreme caution when work with live voltage.
NOTICE: Using any parts other than OEM original spare parts
relieves the manufacturer of all warranty and liability.
