Check of operation
Check whether the type of nozzles being used corresponds
to the type shown in the Burner Table.
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
The burners of the ovens solid top are fitted with a primary
air regulator.
In the Burner Table, the adjustment measure given is H.
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
When changing to another type of gas, e.g. from natural to
LP, or to another gas group, nozzles must be used which
are suitable for the burner as shown in the Burner Table.
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".
GAS RINGS
Replacing the burner nozzles LGHT POWER
(gas rings Fig. 2)
To replace the nozzle (1), remove the grid, the burner cap,
the burner and the spill tray.
Replace the nozzle (1) (see Burner Table).
The burner has no pilot light.
The burner has no air control (it is with fixed air).
Replacement of the ECO POWER / S700 burner nozzles
(open rings Fig- 8-9,11)
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).
Checking the primary air only in the ECO POWER /ECO
POWER + AE models / S700 (fig. 8,9,11)
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. 8,9,11), according to the
technical data tables and reassemble the front panel by
following the inverse procedure.
Checking the pilot flame only in the ECO POWER / S700
models (fig. 8, 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 "A" screw (fig. 8, 11) by using a hexagon
screwdriver; the adjustment is correct when the pilot
flame surrounds the "B" thermocouple (fig.8, 11).
When using LPG, completely screw in the "A" adjustment
screw.
After finishing the adjustment operation, reassemble the
front panel by following the inverse procedure.
Adjusting the low flame
(gas rings - 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).
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.
Checking the primary air
Before re-installing the burner, check that the measure
H of the clamp E for air adjustment is correct as per the
Burner Table.
