in Oil Heating
Client hearing explosion sound, intermittent at start up. My guess oil is dripping in fire box after shut down. My diagnoses, put in a oil shut off solenoid. Any Ideas?

First thing I'd look for is delayed ignition. But for the record, IMHO every burner should have at least a delay-on oil valve.All Steamed Up, Inc.

Oh I agree with pre/post purge.
What if the unit hadn't been cleaned in years, or there's a turd ball on the end of the nozzle, bad pump cut-off, loose wire, bad ignitor...you know, the list goes on and on.

draft checked? combustion analysis done? There is a reason for loud start, a oil delay valve is only a band aid, it may make the loud start go away but is not "the problem". did you test the fuel pump? whats the pump pressure and cutout?0

You say "your client", but are you his/her heating contractor? I only ask because you needed 2 sentences for a guess and a diagnosis. A real pro could've done it in one.0

I can’t tell if his last post means that’s what he did initially, or that’s what he did and the problem is solved.
But I do have all I need to know by his first post.steve0 -
