To bleed your oil boiler, you'll need a bleed key. Here's a simple guide:
Steps to Bleed Your Oil Boiler
-
Locate the Bleed Valve: The bleed valve is usually found on the circulator pump or near the burner unit. It's typically a small, square or hexagonal fitting.
-
Gather Your Tools:
- Bleed Key: If you don’t have one, you can usually find one at a local hardware store or online.
- Container: Have a small container ready to catch any water that may escape.
- Rag or Cloth: Have a rag handy to clean up spills.
-
Prepare for Bleeding: Ensure the boiler is turned off and cooled down before starting the bleeding process.
-
Insert the Bleed Key: Insert the bleed key into the valve.
-
Open the Valve: Turn the bleed key counterclockwise slowly. This will gradually open the valve, allowing trapped air to escape.
-
Listen for Air: You'll hear a hissing sound as the air escapes. Be ready to catch any water that comes out.
-
Close the Valve: Once the hissing stops and a steady stream of water flows out, turn the bleed key clockwise to close the valve.
-
Repeat If Necessary: If you still hear air in your system, repeat the process.
Important Considerations:
- Safety First: Always turn off your boiler before bleeding.
- Water Pressure: If you're losing a lot of water, you may need to repressurize your system. Consult your boiler manual for instructions.
- Professional Help: If you’re uncomfortable bleeding your boiler, contact a qualified technician.
Troubleshooting:
- No Air Escaping: If no air or water comes out, the valve may be blocked. Consider a system inspection to identify the issue.
- Excessive Water Loss: If you're losing significant amounts of water, repressurize the system or contact a technician.
By following these steps, you should be able to effectively bleed your oil boiler. Remember to consult your boiler manual for specific instructions related to your system.
