discrepancy between manuals for boiler and burner

in THE MAIN WALL

My, barely alive, Burnham V8H5 steam boiler has been abused for the past 9 years. Now that the boiler is almost dead (i'm trying to squeeze another heating season out of it) and i have very little to loose i noticed that my burner settings are neither here nor there.

And, what's worse, recommended settings from Beckett and Burham differ.

Beckett manual says that my burner should have 1.10x60B noozle (ok, just changed it from 1.35 oil man put in there) with Shutters 10 and Band 1 (ok, just changed it from S7, B1). [1.35 nozle and S7 B1 settings produced very sooty output]

But Burnham manual says Shutters should be set to 10 and Band to 5.
There seems to be a HUGE difference in air influx from Band 1 to Band 5… So which one should it be?

    Printed settings are always nice. However — particularly with potential changes in nozzle or pump pressure — there s absolutely no substitute for setting the adjustments using appropriate test equipment.

    AKA

    A combustion Analyzer

    …and pump pressure gauge.
    Id probably start with Burnham’s settings if it’s the original OEM burner on it. Latest Beckett specs may be different pump pressure settings.

    Is it burning poorly? If not, don't fool with it. It can't be properly adjusted without specific tools & a combustion analyzer, so if you don't have a specific problem you're trying to solve, best to leave it alone.
