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.
1. Use a wrench or screwdriver to loosen holder to adjust or position electrodes.
2. Set gap at 1/8″
3. Set electrodes 1/8” forward from end of nozzle.
4. Set electrodes about ½” from center of nozzle to center of electrodes.
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.

What kind of sealer is used on nozzle adaptor ?
March 5, 2018 at 5:44 PM |
Any pipe joint compound can be used on the threads of the oil line. Do not use Teflon tape. Don’t use anything on the nozzle threads.

are the adjustments for electrodes the same for waste oil furnaces?
March 5, 2018 at 5:59 PM |
Adjustments should be the same, just remember to set according to the nozzle angle of spray.

Will running the heater all day along with deisel fuel cause the electrode to burn away ?
March 5, 2018 at 6:08 PM |
If you have a digital electronic primary control, the electrodes only fire long enough to ignite the oil and then shut off. Running all day would not affect the electrodes. However; the older style primary controls, like the Honeywell R8184G, fire the electrodes continuously. Running these heaters all day long would cause the tips to burn away faster.

Chart was a big help, made changing nozzle and electrodes a 20 min job. Thank you
