How to Bleed an Oil Furnace: 7 Steps
Bleeding an oil furnace is essential for ensuring its efficiency, safety, and continued operation. Over time, air can become trapped within the oil lines, which can lead to inefficiency and even breakdowns. In this article, we will discuss the seven steps you need to take to bleed your oil furnace correctly.
1. Gather the necessary equipment: Before you begin bleeding your oil furnace, make sure you have a wrench or pliers, a proper container for collecting waste oil (such as an old soda bottle), a clean rag, and a screwdriver.
2. Turn off the power: For your safety, always switch off the power supply to your furnace before working on it. This may involve turning off a circuit breaker or simply unplugging the unit.
3. Locate the bleeder valve: The bleeder valve is typically found on the burner pump’s side or in the oil burner control unit. Look for a small metal nut with a hose connected to it.
4. Place your container: Position your chosen container beneath the bleeder valve to collect any waste oil that may come out during the bleeding process.
5. Loosen the bleeder valve: Using your wrench or pliers, gently loosen the bleeder valve by turning it counterclockwise. Do not fully remove the valve – just enough to see oil starting to seep out.
6. Turn on the power and bleed: With the bleeder valve loosened and your container in place, turn the power back on and allow your furnace to run for a few minutes. During this time, you should see oil and air bubbles coming out of the loosened valve and into your container. Once there are no more air bubbles and just a steady flow of clear oil, turn off the power.
7. Tighten the bleeder valve and clean up: With all trapped air removed from the system, tighten the bleeder valve using your wrench or pliers. Wipe away any excess oil with a clean rag and dispose of the waste oil properly, following local regulations.
By following these seven steps, you will successfully bleed your oil furnace and ensure its optimal performance. Regular maintenance and bleeding are essential for the long life of your furnace and can save you money on repairs and energy bills.
