WEEKLY:

*The de-coking rod must be operated at least once per week to eliminate carbon deposits that build up where oil enters the burner bottom:

1.Remove front burner access cover.

2.Slightly back brass packing nut off (counterclockwise) to release de-coking rod. (Be careful as packing nut may be hot. A glove may be necessary.)

3.Slowly draw rod out until it stops while rotating 360 degrees several times. A small pair of pliers or vise grips may be helpful. This rod has a scraper internally that scrapes away carbon from inside the line.

4.While still rotating, push the rod back in until it stops and tighten the packing nut snugly.

5.Replace access panel.

*Note: If flame is burning lower than expected, you probably have carbon build-up in the line or burner bottom near fuel inlet.
