How to Install Oil Furnace Replacement Electrodes How to Install Oil Furnace Replacement Electrodes
Oil furnace replacement is a difficult task if you are unfamiliar with the inner workings of your furnace. The electrodes, for instance, are a good example of the sensitive pieces that comprise your furnace. You will have to use great caution whenever you are installing replacement electrodes. They can be very dangerous if they are not handled carefully. You will find that there are several things that you can do to make sure that this job is done correctly and safely.
Step 1: Remove Old Electrodes
Once you have cleaned up the general area with a rag, you will be ready to begin. The first thing that you should do is get the old electrodes taken out so that you will be able to get the new in. You will need to compare the two to make sure that they are the same and you will have no issues with your replacement electrodes. Check the model numbers to make sure that they are as they should be.
Step 2: Screw in Replacements
Whenever you are installing the replacement electrodes be careful that they do not touch each other. Once you have them in place you will need to get out your screwdriver and tighten the screws into place just enough so that the electrodes can still move back and forth a little bit. You will want them to still be able to stay into place.
Step 3: Setting Electrodes
There are guidelines that you can follow that will generally work well if you do not have the manufacturer’s instructions. You will need to get your electrodes set level with the plane of the nozzle from your firing assembly. The gap should range in size from 1/8 to 3/16 inch. You will want the electrodes to be set between the flame retention ring and the top of your nozzle.
Step 4: Adjust
Get out the calipers and adjust the electrodes. Make sure that the distance that is set between each of the electrodes is what your manufacturer’s instructions recommend. Typically, you will find that the electrodes should be in the space of two pennies. However, you should still check with the instructions as each and every oil furnace has different instructions. Once you have them in the correct distance you will need to focus on adjusting the backward and the forward alignment. Once you have the electrodes placed in the correct position, you are ready to tighten up the screws so that they are securely in place.
Step 5: Reattach
Once your electrodes are back into place you are ready to get the firing assembly line replaced and reattach your oil line. Pay close attention to the connections before you test your furnace. The oil that is at the cut-off valve needs to then be turned on. Once you have done this you are ready to turn the power on at the circuit breaker.
