Dear Team,

I have an Embassy Onex Condensing boiler that goes through its 3 to 4 restarts and ends in an L 01 code. I have an ignition and just changed the ignitors. Pressure is between 15-18 psi. Need some advice.

Many Thanks,
Robert S.

    Fuel type?

    Gas pressure (static reading, drop at ignition, and if it lights off measure the high lockup when burner shuts down)

    can you tell if it lights off at all?

    How does the flame sensor look?

    pictures please showing gas line, venting etc
