4.2 POSITIONING
Place the oven under a suction hood to make sure all vapours and products of combustion are extracted.
Install the oven horizontally and check the correct positioning by means of a level; rotate levelling feet to adjust.
The oven may be installed on its own or in a group of several elements; but make sure it is not placed next to combustible
objects.
- Never obstruct the air vents and heat dissipation openings of the oven.
- The electric cable must never be subject to traction.
- Provide clearance of 1/2 metre on the right of the oven for maintenance.
4.3 COLD WATER CONNECTION
(SOFTENED)
Water pressure: min. 50 kPa max. 400 kPa (0.5 <PH
2
O < 4 bar).
The water inlets must be connected to the softened supply
network at a maximum temperature of 50°C by means of
shut-off valves, to be closed when the oven
is not being used or for maintenance work.
The water is used to condense the vapours in the
waste water outlet, to supply the humidifier and
to generate steam; between the shut-off valve and
the oven connection pipe, there must be a mechanical
filter so as to prevent any ferrous waste getting
inside that could over time cause oxidation of the
oven.
If the hardness of the water is greater than 5-7°Fr, it is
necessary to install a softener with automatic
regeneration, to be positioned after the mechanical filter.
As regards the flow rate per hour of the softener, refer to the Table on page 4.
The oven is equipped with a water pressure regulator: once the oven has been started, turn it onto the steam function and
check the following pressure on the pressure gauge located near the solenoid valve.
FGMD67 0.4 bar
FGMD107 0.75 bar
FGMD207 1 bar
If the pressure does not correspond to the figure given here, release the control knob by pulling it, turn it onto the desired
pressure and then press it to lock it.
4.4 WASTE WATER OUTLET
The water outlet “1” must lead
to an open siphon “2” so as
to allow no contact between the outlet pipe
of the oven and the collecting siphon
as per the current local health regulations
and for the oven to work properly.
To prevent bad smells and waste water getting
back into the oven, after the open siphon there
should be a normal siphon “3”.
The drain pipe is to be manufactured
with materials able to withstand temperatures
of 100°C.
N.B. ”Closed” connection to the channel is NOT allowed!

4.5 ELECTRICAL CONNECTION
- The electrical connection must be carried out by qualified authorized personnel only, in compliance with the regulations in
force. Check the data reported in the technical data Table on page 4 of this manual, on the adhesive connection label on page
11 and in the wiring diagram.
The connection envisaged is fixed.
IMPORTANT: A multi-polar mains cut-off device must be provided upstream from each oven, with a contact opening gap of
at least 3 mm.
For example:
- a manual switch of suitable capacity, equipped with fuses
- residual current device.
4.5.1 EARTHING
It is vital to earth the oven.
Connect the terminals marked by the symbols ( ) positioned on the line-in terminal block to an efficient grounding
complying with the regulations in force.
CAUTION: NEVER CUT THE GROUNDING CABLE (yellow-green)
THE MANUFACTURER DISCLAIMS ALL RESPONSIBILITY IF THESE SAFETY STANDARDS ARE NOT
COMPLIED WITH.
4.5.2 EQUIPOTENTIAL SYSTEM
The oven must be included in an equipotential system whose efficiency must be checked according to the standards in force.
The screw marked by the ”Equipotential” label is near the terminal block on the base.
4.5.3 POWER SUPPLY CABLE
The oven is supplied without a power cable. The specifications of the power supply connection flexible cable must match or
be superior to those of the cable with rubber insulation H07RN-F.
As regards the cross-sections of cables, refer to the table on page 11. Introduce the cable through the cable clamp and secure
it firmly. During operation, the power supply voltage should not differ from the voltage rating by +/-10%.
IMPORTANT: For the electronics to work properly, it is essential for the phase to be connected to the phase (Terminal
No.1) and the neutral to the neutral (Terminal No.5) of the terminal block, otherwise the control unit for ignition and
flame detection will shut down.
4.5.4 WIRING THE CABLE TO THE TERMINAL BLOCK
Our gas ovens are designed to operate at a voltage of AC 220...240 V 50 Hz (in case of 60 Hz. power supply, request the
appropriate kit).
If it is necessary to connect the power supply cable:
• Remove the right panel.
• Connect the power supply cable to the terminal block according to the mains voltage, following the wiring diagram and the
adhesive connection label placed near the terminal block.
Fasten the cable-clamp firmly after inserting a sufficient length of cable.
Check that the phase (L1) and neutral (N5) polarities have not been swapped over, otherwise operation would be irregular
and faulty in controlling the flame.

The main feature of this valve is being able to have two power units in the oven, therefore more even cooking, more accurate
temperatures and a longer service life for the oven.
The adjustments are made according to the data of Tab.4.6.1.5.1. The inlet and outlet pressures should be checked with a
pressure meter (in mbar) at the test points on the valve. Alternatively, the pressure gauge can be connected to the test point on
the ramp (inlet) and on the nozzle (outlet).
Adjusting the outlet pressure at the nozzle:
Maximum pressure
Connect the oven to the gas socket, on the display set min. 250°C (to prevent the oven reaching the set temperature before
finishing the adjustment) on convection, manual, and Start.
Take off the cap C, turn the nut B (use a 10 mm wrench) clockwise to increase the pressure,
anticlockwise to decrease it. Set the pressure to the value of Table 4.6.1.5.1.
Caution
: Do not screw too far clockwise as this could irreparably damage the valve
(see outlet pressure in Table 4.6.1.5.1).
Minimum pressure
Make this adjustment only after completing the maximum pressure adjustment.
Disconnect the blue wire of the black cable leaving the SMD valve (central valve) from the male-female fast-on connector to
permit
the valve to work only with the minimum pressure.
Keeping the nut B locked with the wrench, turn the screw A (cross-head screwdriver) anti-clockwise to decrease the pressure
or vice versa. The outlet pressure should be adjusted according to the table.
Fit the protective cap C back on, reconnect the blue wire in the male-female fast-on connector: the valve is adjusted according
to the
chosen gas.
Check: Cool the oven, set convection 150°C, press Start and, with the pressure meter, check that the
pressure at the nozzle is:
- maximum (see Table 4.6.1.5.1) when the temperature shown on the display is < 145°C
- minimum (see Table 4.6.1.5.1) when the temperature shown on the display is between 145°C and 149°C.
