Oil Boiler Will Not Fire


It got a new 1.50/80 nozzle, fuel filter, pump screen and electrode kit (all set to specs) really cleaned up the spray pattern.

I was looking at the flame pattern in the box, alot cleaner than it was before. It was almost blinding before like the oil was coming out of a garden hose in a stream.

And wonder why each year the boiler/furnace would be sooted up more then it was in the previous year.

A new nozzle every year saves far far more then it cost.

After a few filthy-30F callbacks at night we change the nozzle every time. I wonder if there are stats as to how much a properly setup burner with a combustion analysis and barometric setup will save versus a visual setup. I am sure that with the outrageous price of oil it would more than pay for itself. If it ain't in writing homeowners won't believe it. The oil companies would like to keep that info private. Them Sheiks like their racing camels and Dubai Tower etc.

I use to have a paper on that years ago. No idea where it is now.

Several oil service trade groups/organizations(not oil providing companies) had done test on eye ball and combustion testing set up units. And had an average efficiency difference. I thnk it ws 6% min at season start up, and of course increased by the end of the year from soot build up on the eye ball systems.

3 Bucks an hour, wow you must be "experienced". LOL. I started at $13, charged about $40. I hope you gave yourself a raise. My "eyeballin" ain't as accurate as it used to be so we would be out by at least 10%.
Fits right in with my siggy below.

My first real job was "honorable dishwashah" at a Chinese restaurant. Great place to get started, free food, cute waitresses, except for the nightly ritual of cleaning the baked on rice in the huge pots, ugh.

OK so now it's all back together and running. What is the

Over fire draft
Draft at the breech
O/2 or CO/2 reading
Excess air in %
How about the smoke reading is it a trace or is it higher?
What is the flue gas temperature at the breech?

There is a whole lot more to setting up an oil burner than getting the right nozzle and the electrodes set in there correctly. Any one of the above settings are off and you could be either throwing money up the flue, rapidly sooting up the boiler or producing carbon monoxide. Without a combustion analyzer and the experience to operate it and make the proper settings, fiddling with an oil (or gas) burner can have some disastrous results.

Now a buddy of mine would say that that was an anti DIY post, but believe me, I care more about your and your family's safety than I do about being politically correct. Get a technician out to check your work post haste.

I appreciate your concern NH; my buddy has a meter that is getting recalibrated and he should have it back today or tomorrow to check readings.
