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 (3.11.4 "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 (3.11.3 "Adjusting the pressure").
