3.4.1 TRANSFORMATION FROM NATURAL GAS (G20-
G25-G25.1) TO LPG (G30-G31).
For the transformation from natural gas to LPG proceed as follows
mount nozzles that are supplied in a bag with the oven. For the
transformation proceed as follows:
- Close the gas tap.
-Interrupt the power supply by unplugging the cable of the
power supply unit from the socket .
- Remove the burner cover (fig. 20 item M).
-Remove the fan from the burner head using 4 bolts (fig. 24 item P).
- Remove the Venturi cone from the gas valve using three screws
(fig. 24 item Q).
-Insert the stainless steel nozzle inside the seal between the burner and
the fan head (fig. 25 item R).
-Insert the brass nozzle inside the seal between the gas valve and the
Venturi cone (fig.26 item S).
- Carry out the steps in reverse order to reassemble the fan and
Venturi cone; ensure the nozzles are positioned adequately and tighten
the 4 bolts (tighten crosswise) and 3 screws.
-Remove the seal from the gas set on the Venturi cone (fig.22) and
set with a screwdriver at X = see technical TAB.1 for the type of gas
supply.
WARNING!
Check X with a gauge for accurate results.
- Reconnect the power.

SETTING FOR THE TYPE OF GAS SUPPLY AS PER POINT
3.4.4 PROCEDURE
- Open the gas tap.
- Loosen the retention screw inside the gas valve output pressure
takeoff (fig. 27 item T)
- Connect the pressure gauge correctly reset to the pressure takeoff.
- Turn the appliance on as indicated in the instructions.
-At start-up the pressure value initially varies; wait until the burner is
lit, then check the pressure at that point. The value must be 0 mbar,
otherwise remove the gas valve (fig. 28 item U) and adjust the screw
underneath (fig. 28 item Z) until the pressure value reaches 0 mbar.
- Turn the appliance off as described in the instructions.
- Remove the pressure gauge.
- Fasten the retention screw (fig.27 item T) and put the cap on the gas
valve (fig. 28 item U)
-Check the gas infeed pressure as indicated in point 3.2.2
- After connection when the oven is on, perform a gas leak test of, with
particular attention to areas operated, with a spray leak detector, which
does not cause corrosion. Never use an open flame to search for gas
leaks.
-Switch off the appliance.
- Fix seals on the gas regulator at the Venturi cone and if disassembled,
reset on the cap gas valve red heat-resistant paint.
- Reassemble the burner cover (fig. 20 item M) and ensure there are no
holes where unfiltered air can flow (T75G).
WARNING!
When the operation is completed place the
plate with the correct data for the gas for which the oven was
transformed (see fig. 2 item G) above the previous.
3.4.2 TRANSFORMATION FROM NATURAL GAS TO LPG
(G30-G31) NATURAL GAS NO (G20-G25-25.1)
For the transformation from LPG to natural gas proceed as follows:
- Close the gas tap.
-Interrupt the power supply by unplugging the cable of the power
supply unit from the socket .
- Remove the burner cover (fig. 20 item M).
-Remove the fan from the burner head using 4 bolts (fig. 24 item P).
- Remove the Venturi cone from the gas valve using three screws
(fig. 24 item Q).
- Remove the stainless steel nozzle inside the seal between the burner
and the fan (fig. 25 item R).
- Remove the brass nozzle inside the seal between the gas valve and the
Venturi cone (fig.26 item S).
- Carry out the steps in reverse order to reassemble the fan and venturi
cone; adequately tighten the 4 bolts (tighten crosswise) and 3 screws.
- Remove the seal from the gas regulator on the Venturi cone
(fig.22) and set with a big screwdriver at X = see technical data TAB.1
for the type of gas supply.
WARNING!
Check X with a GAUGE for accurate results .
