that shown in the table on burners. Check whether the
pressure reducer used has a flow rate greater than the sum
of the consumption flow rate of all connected equipment.
Check that the gas supply pipes are adequate.
Checking the oven and gas rings pilot light
When correctly adjusted, the pilot light flame will
completely surround the thermocouple; if it does, adjust
by turning the gas and/or primary air adjusting screw.
Checking the primary air (FG, T 900 serie)
The burners of the ovens solid top are fitted with a primary
air regulator.
In the table on burners. The measure of adjustment H is
given.
Checking the functions
- Start the appliance;
- Check the gas tubes for leaks;
- Check the burner flame, also at minimum.

Note for the installer
- Explain and demonstrate to the user how the machine
works according to the instructions, and hand him this
manual.
- Remind the user that any structural alterations to the
room housing the appliance may affect the combustion
air supply.
Running the appliance on other types of gas
To change over to another type of gas, for example from
methane to liquid, use the correct type of burner in
accordance with the table on burners.
The nozzles for the burners and pilot light for different
types of gas, marked in 100ths of mm, are in a case
supplied with the appliance.
When the appliance has been transformed or adapted,
recheck its functions as described in paragraph "Checking
the functions".
Replacing the burner nozzles (gas rings - Fig. 2)
To replace nozzle (1(, remove the grid, the burner cap, the
burner and the spill tray.
Replace nozzle (1( (see table on burners(.
Replacement of the S700 burner nozzles (Fig. 11)
To replace the nozzle (C( remove the front panel by
loosening the upper and lower screws. Before replacing
the nozzle, in model with electric oven, make sure that
the omnipolar switch placed before the appliance is
disconnected. Replace the nozzle (C( (see Burner Table(.
Adjusting the low flame (gas rings and S700 - Fig. 2)
Adjust the low flame screw as follows:
- when using LPG, tighten the minimum adjustment
screw (2( all the way down;
- when using natural gas, turn on the appliance. Turn
the knob to low and regulate the flow with screw (2(
(clockwise = decrease in flow; counter-clockwise =
increase in flow(.

Adjusting of the pilot light (burners opened - Fig. 2)
V kW: Hz: 50/60
Remove the grid and tray from the top and use a 7 mm
hexagonal spanner to adjust the pilot light.
The nozzle is correctly set when the flame surrounds
the thermocouple. When using LPG, the adjusting screw
should be completely tightened.
Checking the pilot flame only in the S700 models
(Fig. 11)
To gain access to the pilot flame, disassemble the front
panel by unscrewing the upper and lower screws.
Before carrying out the adjustment in the models with
the electric oven, verify that the omnipolar switch, placed
upstream of the equipment, is switched off.
During the adjustment, the pilot flames must be on. Adjust
the "A1" screw (fig. 11( by using a hexagon screwdriver; the
adjustment is correct when the pilot flame surrounds the
"B" thermocouple (fig. 11(.
When using LPG, completely screw in the "A1" adjustment
screw.
After finishing the adjustment operation, reassemble the
front panel by following the inverse procedure.
Check the primary air
After changing the nozzle, as described above, check
that measure H (Fig. 2( of the primary air adjustment is in
accordance with the data in the table on burners.
Checking the primary air only in the S700 models
(Fig. 11)
After replacing the nozzle, check the primary air.
To carry out the adjustment, disassemble the front panel
by unscrewing the upper and lower screws.
Adjust the "H" measure, see (Fig. 11(, according to the
technical data tables and reassemble the front panel by
following the inverse procedure.
FG1 SERIES GAS OVEN
Replacing the burner nozzle (gas oven type FG1 - Fig. 3)
To gain access to the oven burner simply remove the
bottom panel (inside the cooking chamber(.
Remove the screw D and extract the burner by pulling
it outwards while taking care not to damage the
thermocouple fixed to the burner. Use the special spanner
to loosen injector C and replace it with the right one for
the type of gas used.
To fit the burner back on again, follow the same
instructions in reverse order.
Adjusting the minimum (gas oven FG1 - Fig. 3)
After having removed the contro panel, adjust the low
flame screw (N( as follows:
- when using LPG, it should be fully screwed down;
- if natural gas is used:
1- Find the knob of the corresponding cock.
2- Turn on the burner, set the maximum temperature and
once it reaches it, turn it to the minimum.
3- Adjust the minimun flow by means of the screw N. The
flow increases by loosening the screw and decreases by
tightening it.
4- Once the flame is considered suitable for a minimum
