Vent gas fireplace through floor to basement exit

[Sharon k]

I want to install a gas fireplace on an inside wall. Can I vent through floor to crawl space then vent it outside. It’s about a 15 foot run to outside wall.
Any information is helpful. I was looking at ventless fireplaces from Lowe’s and Home Depot. My first choice is to buy one that is vented
Thanks

None that I know of can vent down.

there are some fire places that have a power vent, which makes your venting scenario almost Limitless. But only the upper end of the price range offer this. If you value your health, I would never go ventless.
