It is important that you keep your oil furnace parts clean so that your furnace will be able to last for as long as possible. Knowing how to clean certain parts of your oil furnace, such as your oil furnace nozzle is crucial so that you can learn the inner workings of your furnace in order to maintain it for as long as possible.

Step 1 – Prepare

The first thing that you will need to is take a good look at the nozzle to see how bad it is. You may end up needing to replace it. However, cleaning it is something that you should first try. You will need to place the nozzle in the metal container and put just enough kerosene in it to cover it. Once you have done this you are ready to get your furnace nozzle. You will first need to make sure that you have your furnace completely shut off as this could be very dangerous with a running furnace.

Step 2 – Remove Nozzle

Your oil burner gun will have the oil burner nozzle. Simply remove the nozzle; this can usually be done by hand by simply twisting it free. If you are having problems with removing it then try a pair of pliers. Use caution with these pliers as they could end up doing damage to your nozzle.

Step 3 – Soak

Drop the nozzle into the container filled with kerosene. The nozzle itself will need to set for about a half an hour to make sure to get all of the soot and debris off of it. Once you have taken the nozzle out of the kerosene get out your rag and wipe it clean. If there looks to be any debris still hanging on then get a can of compressed air and blow it off. If your nozzle still looks dirty then you may want to allow it to soak for a little bit longer before you put it back.

Step 4 – Remove Sintered Filter

Before you put the nozzle back into place you will need to take off the filter that is at the end of the nozzle. There is a brass screw pin that you will need to remove so that you can look in to see if the steel orifice disk has any clogs. As long as everything looks like it is clean and clear you can put it all back together.

Step 5 – When to Replace

Oil furnace nozzles are inexpensive and should eventually be replaced. If you have cleaned the nozzle and checked the interior of it and it looks to be clogged then you will need to simply replace it. You can usually find these nozzles at any home improvement store for fewer than ten dollars. It is good to always have one on hand just in case you end up needing to replace it even after a cleaning.
