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(.
Adjusting the low flame (gas rings)
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)
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.
GAS RINGS
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.
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
setting , check that it corresponds to the minimum
capacity indicated in the table on burners.
5- If the power is less than the value in the table, turn the
minimum screw again and repeat the check
6- If the power is greater than the value indicated in the
table, tighten the minimun flow screw and repeat the
check.
FG SERIES GAS OVEN AND TUTTOFORNO T
Replacing the burner nozzle (gas oven FG - Fig. 4.0
and 4.1)
Remove the bottom guard "A" . Loosen screw (2( fixing the
primary air bushing and push the latter into the Venturi
tube.
The nozzle is now perfectly accessible.
After replacing the nozzle according to the type of gas
being used and the technical data, reassemble everything
and adjust measure "H" (see table on burners(.
Replacing the burner nozzle (Tuttoforno T - Fig. 4.2)
Remove the bottom panel inside the cooking chamber.
Unscrew and remove the primary air regulator (1(, then
replace the nozzle.
After replacing the nozzle according to the type of gas
being used and the technical data, reassemble everything
and adjust measure "H" (see table on burners(.
Adjusting the pilot flame (gas oven T - Fig. 4.3)
Remove the bottom. Remove the bottom and use a 7 mm
hexagonal spanner to adjust the pilot light.
When using LPG, the screw (11( must be tightened all the
way down.
