I have an EFM 520 dual fuel boiler and attempted to switch over to oil from coal. It looks as if the the nozzle is plugged. Anyone have a photos, drawing, or directions to removing the nozzle and the best means of cleaning it ???CER

The nozzle should be replaced. Don't overtighten it when re-installing. The oil burner should be used at least once a month to keep the fuel in the nozzle tube fresh. Run it for a few minutes each month.

Thanks for the info, had hoped I'd be able to just clean it, but.. Oh well.. I'm all new to this stoker/boiler stuff and trying to catch up with the learning curve. Any idea on the cost of a new nozzle assembly ??

Less than 5 bucks for a nozzle retail. Note the size and spray pattern when you go shopping, or just take the old one with you.
If you haven't changed the filter lately, they are another 5 spot. They (nozzles) don't clean well, and are so cheap, it's easier to replace them. Might want to buy a spare to have on hand.

The nozzle is a 1.50 80 degree hollow. The tube should be OK or can be cleaned while leaving it in place. Finger tighten the nozzle and then just a bit more with the wrench.

Yeah, that too. Be careful when inserting it, not to get the electrodes out of whack.
