Follow the fuel line from your tank, the place where it enters the boiler should have a brass coupling that can be loosened just a bit to let the trapped air out and then re-tightened, put something underneath to catch any that drips.

Bleeding air from oil burner

If you have a Suntec fuel pump on the burner, there is a small fitting which looks like a brake bleeder or grease fitting. This fitting will be at the 5 o'clock position as you look at the face of the pump. Get a 3/8 wrench & cup or bottle. Start the burner, open the fitting with the wrench, & catch the discharge from the fitting in the container. When the fuel runs a clear red with no air close the fitting & the burner should fire.

With Grundfos pumps (sometimes private labled as Beckett) the bleeder is on the bottom, with a Webster pump the bleeder is at the top & if angled at 90 will take a 7/16" wrench.
