What you get

The Empire MV 34 Natural Gas Vent-Free Gas Fireplace is a vent-free gas fireplace rated by its maker at 21,000 BTU per hour.

At full fire it burns about 20 cubic feet of natural gas an hour (its 21,000 BTU/h divided by EIA's heat content for each fuel).

Vent-free means no pipe: combustion air comes from the room and the exhaust stays in it. The manual's room-size and altitude limits and its oxygen-depletion sensor are part of using it safely; check local code first. Vent-free vs direct-vent.

Fuel, per the listing: Natural Gas. Never connect a gas heater to a fuel it isn't set for.

Also on the listing: overall dimensions of 14.87 in (D) x 37 in (W) x 32.68 in (H) and ceramic construction.

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.
