What you get

The Ashley Hearth AGVF340LP Propane Vent-Free Gas Fireplace is a vent-free gas fireplace that its maker rates at 34,000 BTU per hour and says heats up to 1,200 square feet.

Makers rate heating area in their own conditions, so read 1,200 square feet as a ceiling; the size calculator lists the closest fits for your space.

At full fire it burns about 0.37 gallons of propane an hour (its 34,000 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: Propane. Never connect a gas heater to a fuel it isn't set for.

Also on the listing: overall dimensions of 16.5 in (D) x 38 in (W) x 23.75 in (H), a shipping or unit weight of 90 lb and cast iron, oak, wood construction.

Warranty, per the listing: 3 years on burn chamber and valve. 1 year on cabinet and other parts.
