I have a fairly new Peerless series WBV/WV oil boiler that seems to have dirty jets. This is my first winter with an oil boiler and I am trying to learn the ins and outs of it. My problem is after filling the tank which unbeknown to me was almost empty, the boiler starts and stops, needs reset and sounds like flare ups occur. I am assuming the oil line may have brought dirt in the burner area and possibly clogged it somewhat. The unit has a canister oil filter on the outside similar to a auto engine filter. Would changing this be a good start? Does it require any bleeding of air or anything else? All input appreciated.

Changing it is a good idea. Once you change it, you'll likely need to re-prime your system...if you dont, it'll run for a little bit and then get air and likely go into a lock out.

Hopefully the issue is only the filter being plugged....if not, you may need to replace your injector jet.

Probably needs the oil filter and nozzle changed.

But, before doing that. Turn off the power to the boiler. Look on your flue pipe, you'll see a funny looking thing. Its a barometric damper/draft regulator. Open it up, and look inside it to see how dirty it is. Might need a flash light depending on your basement.

If its got a lot of soot in it. chances are, so does your boiler. And it should be cleaned. Not always an easy task.

PS: Turn your boiler back on after your done looking in the barometric damper.

Then decide if you want to have a company come out and clean and tune your boiler. or if you have 2 plus hours to do it yourself. Along with a good vac to suck out the soot.

BESIDES replacing your canister oil fiter you should consider checking the screen filter, then replace your nozzle injector just in case, i recommend to install a check valve after the filter or in the supply oil line in that case you wont have a lot of air in the system, and when you have done with cleaning and adjusting, bleede the pump and let all the air come out probable 12oz.
"the pressure will go to the return line, but not back to the supply line..."

Putting a check valve on a single pipe system can cause the pump seal to blow out.

When an oil delivery is done in the winter, and the oil is at 20 or 30 degrees.
When its drawn into the oil line, and warms up. It will want to expand, Since it can't push back into the oil tank, it puts too much pressure against the pump seal, And blows it out.
