What you get

The Pleasant Hearth VFF3-26PHDX Dual-Fuel Vent-Free Gas Fireplace is a vent-free gas fireplace rated by its maker at 26,000 BTU per hour.

At full fire it burns about 25 cubic feet of natural gas or about 0.28 gallons of propane an hour (its 26,000 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: Dual Fuel. Never connect a gas heater to a fuel it isn't set for.

Also on the listing: overall dimensions of 15.94 in (D) x 38 in (W) x 38.78 in (H) and metal construction.

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.
