I ran out of oil and got it refilled but i cant get the boiler to turn on how do i do that?

Locate the oil line from the tank and follow to the boiler. The oil line will travel into the pump which is attached to the burner. Where the line goes into the pump. There should be a small fitting on the top side of the pump that you'll have to loosen to let the air out. I always attach a small hose to this fitting about 1/4"-3/8" diameter and direct the other end into a clean empty coffee can. Now loosen the fitting(do not remove the fitting completely, this will cause a mess) and press the red reset on and be ready to tighten the fitting back up once all the air comes out and the oil runs true and uninteruppted for about 5 seconds. When you satified that you have all the air out quickley tighten the fitting and the burner should fire right up. Depending on how far the boiler is away from the tank or how much air is in the line you may have to do this a couple times to get all the air out because the pump will only run so long before it shuts it's self off because no flame was detected. When you tighten the fitting be ready for a big whoosh noise once the oil actually ignites. Whatever oil you collected in the coffee can, you can just pour back into the tank.
