Adjusting Electrodes

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.

You may also use a gauge. Our # 66-105

 

 

 

 

 

Lastly, don’t forget to tighten the adjustment holder nut you loosened in step 1.

 

The table below shows some nozzle setting recommendations

Nozzle degree GPH Figure (2) Figure (3) Figure (4)
45 .75 to 4.00 1/8” to 3/16” ¼” ½” to 9/16”
60 .75 to 4.00 1/8” to 3/16” ¼” 9/16” to 5/8”
70 .75 to 4.00 1/8” to 3/16” 1/8” 9/16” to 5/8”
80 .75 to 4.00 1/8” to 3/16” 1/8” 9/16” to 5/8”
90 .75 to 4.00 1/8” to 3/16” 1/8” 9/16” to 5/8”

If above 4.00 GPH you may need to increase Figure (3) by 1/8” to enable smooth startup.
