How to Patch Holes in an Oil Burner Nozzle Compression and Flair Fitting How to Patch Holes in an Oil Burner Nozzle Compression and Flair Fitting
An oil burner nozzle is the point where the oil streams into the burn chamber in order for the ignition process to happen. This then creates the fire in the firebox for the heat exchanger to transfer into hot blown air. After several years of service a hole can happen within the oil burner nozzle or the flair fitting which holds it to the oil line.
Step 1: Gain Access to Oil Burner Nozzle
Turn off the furnace through the oil shut off switch. Remove the access panel on the furnace with the screwdriver. Once the access panel is removed you will then need to remove the cover to the firebox.
Step 2: Locate Hole in Oil Burner Nozzle
Find the hole in the nozzle. Once it is located, drill the hole to make it smoother and ready for the steel plug.
Step 3: Apply Flux to Hole
Spread a little flux over the hole area and around the steel plug.
Step 4: Repair Hole in Nozzle
Install the plug into the hole and twist it until it sits in place. Apply heat from a torch and hold the solder to the seams between the plug and the nozzle when it gets hot enough. Clean off any metal burrs that are showing to make sure they do not interfere with the burn process.
