In the unlikely event the boiler does not give complete satisfaction, before calling for a service engineer, the installer should check the following:-

General checks

1.Is the mode switch in boiler mode (indicator on)?

2.Is there 230V across the boiler live and neutral terminals?

3.Is the polarity correct? (230V across live and earth, 0V across neutral and earth)

4.Is the air bled from the primary system?

5.Is the air bled from the oil supply?

6.Is the flue sized and routed correctly?

Boiler runs straight to lockout

1.Has the oil line been purged of air?

2.Where an air eliminator is used in conjunction with a top feed oil tank the non-return valve, (if fitted), should be removed from the oil dip pipe.

Boiler locks out at the start of a demand (Heating off overnight for example)

1.If an air eliminator is being used, check that there are no leaks that allow air to be pulled into the oil supply.

2.If a two pipe oil supply is a being used, has a non-return valve been fitted to the inlet pipe? Refer to the instructions for guidelines.

No domestic hot water (external programmer)

1.Is the mains water in connected to the 15mm isolation valve?

2.Is there a domestic hot water demand from the programmer and has the tank reached temperature?

3.Is there 230V on pin 2 of terminal block X4?

4.Remove the external wiring from terminal block X4 and fit a link across 1 and 2, if the domestic hot water now operates there is a problem with the external programmer and/or its wiring.

No central heating (external programmer)

1.Are both programmer and room thermostat on demand for central heating?

2.Is the room thermostat wired correctly?

3.Refit the link across pins LS and LR on terminal X2, if the central heating now operates correctly the room thermostat and/or its wiring are faulty.

4.Is there 230V on pin 1 of terminal block X4?

5.Remove the external wiring to terminal block X4 and fit a link across pins 1 and 3 on terminal X4, if the central heating now operates correctly the room programmer and/or its wiring are faulty.

UNDER NO CIRCUMSTANCES MUST AN APPLIANCE BE LEFT

TO OPERATE WITH ANY CONTROL LINKED OUT OR OVER RIDDEN.
