How do I adjust my electrodes?
Adjusting electrodes in your oil burner is something normally done by a professional, however it is not rocket science. If the homeowner is capable of doing most home repairs, he/she can adjust electrodes. The standard cautionary notes apply: make sure you turn off the system, and be careful because you are working around fuel oil. Make sure you don’t over-tighten the holder, you do not want to crack the porcelain. If you do not feel comfortable, defer to a professional.
