beckett oil burner ignition issues on reinstall of boiler in new location

I have purchased a burnham 1 year old (sat unused for 2 years) V8 3h steam boiler and converted it to hot water with trim kit supplied by burnham.
installed a new oil tank, fuel is a 1 year old. new lines to beckett model AFG.
when fired, lots of white smoke. bled air then it was ok for 2 running cycles. the next day same white smoke and unit goes into lockout. ran through 5 or so complete cycles to clear smoke, but no luck.
I did remove inline filter to try with same result.

what is going on? what can I try?

Here are some answers I found on the net.

It means you've chosen a new pope, congratulations.

Water in the oil.

Ignition failure when the chamber is still hot.

My own guess, air is getting in the line. Tighten everything including the 4 bolts on the screen housing.

What about a crack in the boiler and what you are seeing is steam? Or maybe it's Holy Water...

thanks for the quick response,
i did see a split in the gasket on the strainer cover, but i did not see any leaks when it was off so i did not worry too much. I will try to seal it until it can be replaced.
I did clean the nozzel and now it runs but still sounds like it is not consistant and still smokes.

it does not smell like water, but i fear that there may be an issue in the connection between the boiler and the integrated hot water chamber. when filling the boiler, water came out of the ports for the water heater.. i was told by burnham to leave out the plugs since it was not being used.

Your questions spark many more questions.
1. Is this a one line or two line fuel system? If two line did you install the bypass plug?
2. Where is the tank location to the boiler/burner location?
3. Do the fuel line come out of the top or bottom of the fuel tank?
4. How does it light when it does light?
5. What is the CO2?
6. If you shut off the water valve for a day or two does the water pressure hold?
7. Do you hear a sizzle during firing?
8. Is there rust inside the vent pipe starting to build up?

3. Do the fuel line come out of the top or bottom of the fuel tank? top of tank
4. How does it light when it does light? eratic combustion low warble maybe 85% of perfect.
5. What is the CO2? I dont know
6. If you shut off the water valve for a day or two does the water pressure hold? yes
7. Do you hear a sizzle during firing? no
8. Is there rust inside the vent pipe starting to build up? no new vent
the answers are above. thank you for your help it is a little frustrating.

Where is the white smoke coming from. You mention water coming from your tankless coil. There shoudn't be any water coming from the coil. It is separate from the boiler. Blow the coil out if you can to make sure there's nothing left. If it continues you may have a pinhole in it. You would notice if your boiler loses pressure.

Not such a good idea to do that. Nozzles are cheap. Replace it.

Nozzle "looks" good...

You can't look at a nozzle and tell if it's good or not. Take a look at those three microscopic scratches on this one... it's BRAND NEW out of the tube. Those three minute little scratches were enough to TOTALLY screw up the spray pattern. Treat nozzles as the precision devices that they are. Never re-use one, never clean one... (unless it's an emergency).

I believe the unit had been frozen in the time before i bought it, my guess the coil is split. can i cap it off if that is the case? i do not need it anyway.

With the info supplied I think you may have a couple of things going on.
1. Not a good oil supply due to air in the supply line coming from the top of the tank.
2. Air & draft adjustment.
Buy a new spec nozzle and make sure the air settings are to spec. That is a good beginning and than have it combustion tested.
