How do you Prime a beckett oil burner?

See page 22 picture number 5 for what the pump looks like. On the pump will be a bleed screw. Start burner and open bleed screw allowing air to escape. Close bleed screw right away when air stops coming out.

NOTE this may take more than one time to get the air ouit. If the burner shuts down on safety during the bleeed process close valve right away to not let air get sucked back in since the check valve in the pump could be weak.
