4.Remove the burner and mixer core from the boiler and place it on the floor.

5.Use low pressure air, max. 20 psig, to blow in- side the burner first, then outside of the burner, in order to remove any accumulated dust or lint build-up. Also blow the air down the pilot tube to clean away any dust or dirt

6.Check that the electrode is not touching the wall of the pilot tube. Also be sure the electrode is not cracked and that the ceramic spider is able to move up and down freely.

7.Use a soft, clean cloth to remove accumulated contaminants from the UV radiation tube (UV scanner) glass envelope.
