A 41000-BTU standing propane heater built around a tempered glass tube, so the flame stays visible and the column creates an ambient display as much as it puts out heat. Powerful heat reaches up to 13 feet in diameter, which covers a seating group rather than a single chair. Under the glass the burner is stainless steel, and the body is made of quality magnesium oxide material chosen because it holds up outdoors rather than needing shelter. Ignition is a simple and safe push-button start, and flameout protection cuts the gas supply if the flame goes out on its own. CSA certification applies to the heater. A standard 20-pound propane tank fits in the base and is held by a tank securing ring, though the tank is not included. Adjustable feet and ground fixers steady the 104-pound column on ground that is not perfectly level, and rolling wheels move it smoothly when the warmth needs to be somewhere else. Standing 62 inches tall on a 15.5 inch square base in black, it is intended for a backyard, patio, garden or gazebo. A waterproof cover and an instant touch-up pen come with it, so weather and the occasional scuff both have an answer, and an installation guide is included in the carton.
