How to Change a Oil Filter in your Furnace or Boiler

Posted by on 7/21/2018 to Articles

It is the time of the year we need to check the furnace or boiler that will provide us comfort for the upcoming winter. Much like the oil filter that is in our cars that we need to change with each oil change, each year we also need to change the filter that is located in the furnace or boiler. This filter is a very important part of the system that will insure our furnace or boiler is working to its full potential. The filter will keep small particles and impurities that may be in the fuel that could enter the system causing damage.

 

The filter looks like the oil filter on a car and is located most of the time on near the oil tank or burner. The filter is inexpensive to buy and can be a simple DIY project that will save you money while insuring to help maintain your system. This task could cost you if you hired a professional. You can follow a few simple steps that will help you to save money as well as reduce your heating costs.

 

  • Find the filter housing that is usually near the oil the tank or burner. There should also be a shutoff valve located between the tank and the filter housing.
  • Turn the valve off to make sure you stop the flow of oil from the tank. When you close the valve it will prevent oil from spilling when you remove the filter.
  • Place a small pan under the filter to help catch any oil that might spill over when you loosen the filter housing. This will prevent oil from falling onto the floor.
  • Loosen the retaining the bolt that is usually found at the top center of the filter housing. While holding the filter in your hand take the other hand and loosen the bolt with a wrench. Take the housing apart and remove the filter.
  • Place the new filter into the housing and make sure you replace the old filter housing gasket with the new filter. Place a small amount of oil on the new gasket. Place the filter and housing back filter housing top.
  • Place the retaining bolt back into position and tighten the bolt with your wrench. After you have replaced the retainer bolt and tightened it you will then turn the fuel valve part of the way open and check for leaks. Once you determine there are no leaks you can fully open the valve.
  • Locate the fuel bleeder that is usually located at the top of the filter housing. Opening this valve will remove all the excess air from the filter. When you see a steady flow of fuel coming from the bleeder valve all of the air is gone and the valve can be shut.
  • Dispose of the old filter as well as the lost fuel properly.

 

 By following these simple steps this is a project that can be done yourself saving you money.
