3. You might have a square Electric Box connected to the top of your OCV. This is for automatic oil control. Make sure this plug is turned on, and the Lever on top is switched to "Automatic" (slide to the right side).

4. Open your control door, and remove the inner burner door. Lift the inner door up and out, to remove it from its latches.

5. Wait 15 minutes for the oil to enter the burner chambers and saturate the wicks.

6. Identify the "lighting flap" on the perforated burner shell. It might slide open, or lift open like a flap, depending on the version. Open the flap and light the wick with a match - make sure you don't knock the burner shells as this will affect the burn.

7. Close the lighting flap and re-seat the inner burner door. Make sure it's secure.

8. Switch off the electric transformer plug.

9. After about 30 minutes, look through the viewing glass on the inner burner door and the flames should have settled to a nice blue colour.

10. Switch on the electric transformer plug to resume automatic control.

If your wicks don't light, check that your fire valve hasn't tripped due to any downdraught in the flue.

The fire valve is a circular device with a button and a metal wire entering the aga. It should be located on the oil line, next to your OCV.

Press the button down, to reset the fire valve. If it pops up again, you'll need to wait for the burner temperature to cool before trying again.
