Peerless boiler won't stay on

I cleaned my Peerless boiler with a Beckett burner motor 2 months ago I cleaned it and it was working fine. Now, when the boiler turns on sometimes it doesn't ignite right away. And it trips the reset button. I thought it was the filter and nozzel so I changed it. But, it's still happening.

Also, what are the air shutter and air band adjustments for a 1.00 70 degree A nozzel would be?

Thanks for any help

cutting out

check your chimney draft, tight connections on all fuel piping and fuel pipe vent (outside) no bees... check the strainer is clean on fuel pump if it has one...and fuel!!!!! too much air will blow out the flame also.

When a new oil nozzle is installed the proper adjustments must be made using a flue gas analyzer.The ignition electrode setting are crittall for a smooth oil light off, next the draft regulator in the flue pipe connected to a natural draft chimney must be set in the pipe properly and with burner on set to furnace specs. WE then move on to adjusting the air through burner to establish a trace of smoke using a smoke pump,then check the co2 maximum 12.5 and last the stack temperature this will give the steady state efficiency of the heat exchanger. Modern oil burners will operate at 0 smoke thus converting almost all the oil into heat,therefore without the test equipment in the hand of a skilled operator it is not safe or profitable to do your own burner adjustment.

As Saves has said, these need to be adjusted via the use of some form of combustion analyzer. You can't just 'pick a setting' and run with it, it don't work that way, every situation is different.

There are a number of things that could cause this problem, and unless you are willing to spend the required time to study all about oil burner combustion and how they operate, and invest money in the required test equipment, the best advice at this point is to call a technician.
