How do I disconnect My Flame sensor and clean it?

Hi FP

Here is a link to the furnace manual:

The flame sensor is at the bottom left of the gas manifold and should be obvious on how to remove it once you locate it!

Use some steel wool to clean the end and reinstall... should resolve the issue if this is indeed the issue!
