What causes flame lifting from burner ports in my Trane Furnace?
- KkaitlinsimsSep 7, 2025
If the flame is lifting from the burner ports on your Trane Furnace, you can try: 1. Resetting the manifold pressure (refer to the operation guide). 2. Replacing the regulator section of the combination gas valve or the entire valve. 3. Checking with your local gas supplier for the proper orifice size and replacing it (refer to the operation guide).
