@lee federico nykaza We believe that's an ethanol fireplace. Those don't need to be vented, they don't create smoke. It does not need a blower fan so there is no noise. It doesn't need a vent at all, it just burns the ethanol. We believe it's a fireplace called EcoSmart Fireplaces. Here is a link: https://ecosmartfire.com/product/flex-68by/

Thank you for that information and link. I appreciate it.
