How to bleed your oil furnace or boiler

If your tank ran dry, your burner may need to be bled and primed before it will restart. Follow the steps below, or watch the short video.

How to start your furnace

  1. Get diesel fuel

    Get yourself 10 gallons of diesel fuel from a gas station.

  2. Add it to your fill pipe

    Pour the diesel into the fill pipe on the outside of your house.

  3. Grab a wrench and a bottle

    Get yourself a 3/8" wrench and an empty bottle.

  4. Find the bleeder screw and reset button

    Locate the bleeder screw and the reset button on your unit.

  5. Open the bleeder and press reset

    While holding the bottle under the bleeder screw, crack the screw open with the wrench and press the reset button.

  6. Watch what comes out

    Air mixed with fuel will begin to come out. If the unit shuts off, close the bleeder screw. Once a steady flow of oil comes out with no air, close the bleeder screw.

Repeat steps 5 and 6 until a steady stream of oil comes out, then close the bleeder screw. Your unit will start up.
