[. . . ] The burner pressure is factory preset and no adjustment should be required. Check the burner pressure is within +/-0. 2mbar. If this is incorrect, the burner pressure may be adjusted to the correct setting by turning the hot water gas pressure adjuster (potentiometer), located on the control board. To gain access remove the two screws securing the controls facia, see diagram 9. 1. Using the burner adjusting tool supplied. (clockwise to increase), see diagram 10. 2. Turn the adjuster slowly, always making adjustment by reducing below the required pressure then increasing up to the required setting. Close the hot water draw off.

Disconnect the sensing lead at the connection, see diagram 10. 2. Set the mains electrical switch "B" to 1. The electrode will continue to spark for (10 seconds approx. ) to enable the ignition to be set and checked before going to lockout. Check the ignition rate is set to 6. 0 mbar +/-1. 0 mbar, adjust if required by turning the ignition rate setting potentiometer using the adjustment tool supplied, If this is not achieved before the boiler goes to lockout the process can be repeated as required by pressing the rest button "G", see diagram 3. When set, switch the mains electrical switch "B" to 0. Set mains electrical switch "B" to 1, depress the rest button "G" if required. Isolate the boiler from the electrical supply. Replace plastic plugs, screw cap and adjusting tool. Disconnect the pressure gauge, tighten the burner pressure test point screw . Take care not to splash any of electrical components. Refit control fascia. 10. 5 Gas Rate Modulation The burner pressures are factory preset and no adjustment should be required. When checked if they are not consistant with the information in table 1. Fully open a domestic hot water tap ensure there is no modulation. Turn the domestic burner pressure potentiometer to minimum by turnining anticlockwise with the tool supplied (do not force it), see diagram 10. 2.
