Instructions for the Installer

5. ADAPTING TO DIFFERENT TYPES OF GAS

Before carrying out the operations described below, disconnect the appliance from the electricity supply.

The appliance is tested with G20 (2H) natural gas at the pressure of 20 mbar. If it is to be used with other types of gas, the burner nozzle has to be changed and the gas valve adjusted. To replace the nozzle, proceed as described below.

5.1 Adjusting the oven burner

To adjust the oven burner, open the oven door and proceed as follows:

•remove all accessories (pans, shelves and any steel runners);

•lift the oven bottom plate and extract it so that the inside of the oven is as shown in the picture.

5.1.1 Adjusting the minimum setting (models with slotted front panel)

The oven thermostat has a screw for regulating the minimum setting, visible from the 18th slot of the front panel, starting from the right. When the type of gas used changes, the by-pass must be replaced as follows:

• Remove the top case unscrewing the respective screws.

• Unscrew the by-pass with a straight-head screwdriver and extract it from its housing with pliers.

•Fit the by-pass (supplied) tightening the screw fully

5.1.2 Adjusting the minimum setting (models without slots on front panel)

The oven thermostat has a screw for regulating the minimum setting, accessed by removing the thermostat knob. When the type of gas used changes, the minimum setting must be adjusted as follows:

• Light the oven burner and keep it operating at the highest setting for 10/15 minutes with the door closed. Now turn the knob to the minimum temperature setting, remove the knob and use a straight- head screwdriver to adjust.

•When using bottled gas, the adjuster screw must be turned fully clockwise. The diameter of the by- pass is stated in point “5.2 Burner and Nozzle Data Tables”.

If town gas or natural gas is used, it is sufficient to unscrew the by-pass by a few turns. In both cases, functioning must be tested as follows. Light the oven burner at a temperature of 240°C and leave it on for 15 minutes. Turn the knob to the minimum temperature setting and adjust the by-pass taking the flame to a minimum: it should stay lit although the length is 2-3 mm. This operation must be done with the oven door closed.

After having adjusted the minimum setting try opening and closing the door; if the flame goes out increase the minimum setting a little. Also, make sure that when changing from the maximum to the minimum setting the flame does not go out.

5.1.3 Changing the nozzle

•Undo the oven burner fixing screws A.

•Move the burner B outwards until the nozzle is accessible.

•Use a 7 socket wrench to change the nozzle, fitting the one for the type of gas to be used (see point “5.2 Burner and Nozzle Data Tables”).
