Just to be clear...

I am stating that a homeowner should maintain all their appliances according to the manufacture's recommendations. In the case of my own fireplace, that means I can do most of the maintenance myself.

If I had to choose which appliances and systems I hired a pro to inspect and maintain, a gas fireplace would be near the bottom of the list. Certainly behind the electrical wiring, and behind other gas appliances. A car would be #1 on the list.
