Steel construction and an aluminum reflector cover define this gray standing patio heater, which drives 50000 BTU through a stainless steel heating mesh in a 360 degree pattern. Warmth reaches roughly 20 ft across and arrives about a minute after lighting, so a gathering does not wait for the column to catch up. Press-and-twist ignition removes the need for matches, and one knob varies flame intensity from low to high. Tip-over protection, anoxic protection and flame-out protection all cut the gas automatically. The post stands 86 inches tall over a 32.5 inch base, weighs 31 lbs and burns from a standard 20 lb propane cylinder that is not included. It arrives in one carton and requires assembly before first use.
