Oil furnaces are used as a heating source for warm air and hot water in many parts of world. Today, pressure burners are popularly used, including the use of oil being sprayed into a combustion chamber at high pressure and electric sparks being ignited. Oil furnaces are simple and uncomplicated and can be fixed quickly if maintained properly.
Step 1 - Turn off the Furnace
Turn off the switch of the heater. When the off button activates, the color on the furnace switch button changes to red. For shutting off the floor of oil tank, a regulator button is available, which stops the flow of the oil to the burner and always shuts in clockwise direction. Place all nuts and bolts on a plate so that you don't lose them.
Step 2 - Use a Screwdriver
In the burner, the filter is put down on a shallow pan and the shutting nozzle has a capacity to pull out all of the dust and dirt. Use a flat screwdriver or wrench for removing screws from the transformer and place them on an old plate. The piano hinge has capacity to carry the weight of transformer when the nozzle is being replaced. Therefore, turn the transformer on its hinge. Use the wrench or screwdriver to loosen the upper bolt of the pump oil line and unscrew it. Repeat the step for the next bolt. Use your fingers to gently rotate the oil line out of its original position.
Step 3 - Removing the Nozzle
Once the screws and nuts are removed, the nozzle can be removed. Use pump-pliers to loosen the hold down nut that holds the nozzle. You may have to use your hands to do this. It is also a good idea to wear rubber gloves during this procedure. Use an old piece of cloth to remove any residue that may have come on the nozzle. Finally, to remove the nozzle, use two wrenches at the same time. The smaller wrench would be used on the back bolt while the bigger wrench would be used on the nozzle itself. You will have to pull the wrenches towards each other to loosen the nozzle.
Step 4 - Replacing the Nozzle
Replace the nozzle. When the nozzle is almost tight, use both the wrenches to push the bolt and nozzle towards each other to tighten it completely. Replace the nozzle in the chamber and rotate it. Next re-insert the fuel tube. Bolt the chamber using pump pliers by replacing the hold-down bolt. Finally, turn the transformer, replace the hold down screws, and using the flat screwdriver or wrench tighten the nuts.
