    I put a new burner in my oil furnace and now it runs but is really loud and sounds like a Lennox Pulse

    What did I do wrong?

    Fuel pressure? Air adjustment? Smoke#? Combustion info?

    I am trying to hire a firm from up north to do a platinum level combustion system efficiency optimization.

    Don’t have the fitting for checking fuel pressure

    It’s a Beckett afg

    The big band is open about 1/8”

    The shutter thing on the side behind the pump is all the way closed. I opened it as far as “4” but ended up bringing it back to all the way closed.

    The smoke test is clean. After 10 pumps the paper is perfectly white.

    Can dig the CA out of the buggy if required.

    And the draft regulator is going wide open and used to not open very far.

    Big band should be closed completely on anything under 1 gph nozzle. The little air shutter is a finer adjustment, start at about halfway open, adjust up until smoky flame tips clear up.

    1. adjust draft regulator to get overfire draft (measured at the flame sight hole) to -.01 to -.02”wc

    2. Using a smoke tester close air till you get a trace of smoke, then open it slightly to get zero smoke.

    If it’s still noisy try different nozzle spray pattern and angle.

    ES is a low flow solid cone. B from Hago is a standard flow solid cone.

    The heat exchanger was just replaced a few years ago. The refractory looks to be in real good shape.

    FWIW,when I was running service at the polar bear, Hago was my preferred nozzle, but if your distributor only has the Hago, maybe try a semi solid cone instead.

    There were times where I would replace the the nozzle with a lower GPH and raise the pump pressure.

    Damper wide open? Got a magnehelic gage?

    Set your stack draft to -.04
    And as @Zman said, put in a semi solid nozzle.
