What you get

The Superior VRT3542 Vent-Free Gas Fireplace is a vent-free gas fireplace; its listing doesn't state a heating area or heat output, so size it with the maker's manual.

As a vent-free unit it burns room air and releases its exhaust and moisture into the room, so nearly all its heat stays indoors. Its manual sets a minimum room size for its BTU rating, and some local codes restrict vent-free appliances. Vent-free vs direct-vent.

The figures, from the maker

Each figure is the maker's or the listing's own, with its source marked. A figure the maker doesn't give is shown as not stated.
