is

7.Activate the "ON mode" by going through the following steps:

-Press the blue arrow once () to position the cursor in front of ON and

press . The display shown here will appear.

»START OPERATION ^ CHANGE SETPOINT

ÈTset=65ÉC

- Confirm the by pressing START OPERATION. The appliance is now in the "ON mode" and will ignite.

8.Once the display shows the text RUNNING you must wait about 1 minute before reading the dynamic pressures (the fan needs this time to run up to full rotational speed).

9.Use the pressure gauge to read the supply pressure at 1nipple

(1) (3.4.3 "Gas data").

Note

Consult the mains gas supply company if the supply pressure is not correct.

10.Use the pressure gauge to read the burner pressure at nipple

(2) (3.4.3 "Gas data").

If the burner pressure is not correct and the appliance is fitted with a blank plate, you will not be able to adjust the pressure. Finalise (3.13.4 "Finalising"), and in this case, consult your installation engineer or supplier.

If the appliance is indeed fitted with a burner pressure regulator, the pressure can be adjusted as described in the procedure (3.13.3 "Adjusting the pressure").

3.13.3Adjusting the pressure

1.Remove the cap (4) from the burner pressure regulator (3).

2.Correct the burner pressure by turning the adjusting screw (5), depending on the correction required:

-Adjustment screw anticlockwise: burner pressure decreases.

-Adjustment screw clockwise: burner pressure increases.

3.Cover the opening of the adjusting screw and check the burner pressure against the value given in the gas table (3.4.3 "Gas data").

4.If the pressure is not set correctly, repeat the preceding steps until the correct pressure is attained.

5.Fit the cap (4) back on the burner pressure regulator.

6.Activate the "OFF mode" of the electronic controller:

MENU »OFF ^ ON

ÈWEEK PROGRAM

7.If the MENU is not displayed: press .

-Use and to place the cursor beside OFF.

-Confirm with .

8.Wait until the fan has stopped, and switch the electronic controller off.

Caution

Failure to wait until the fan stops can cause damage to the appliance.

9. Finish off (3.13.4 "Finalising").
