DIY RV Furrion fireplace squeak / noise fix

The fireplace in my fathers RV was making a squeaking/creaking noise whenever turned on. He took it apart and was able to figure out how to fix it by applying some grease. To do this fix you need a few tools and some general mechanical knowledge.

Good idea but the video is just talking, doesn't actually show any of the process. Sure I can figure it out once I get the fireplace taken apart.
