This patented radiant 6000 BTU to 12000 BTU Liquid Propane heater connects directly to one 1 lb. cylinder and is the perfect solution for heating enclosed spaces like cabins up to 300 sq. ft. A swivel regulator gives you the ability to adapt usage from disposable cylinders to a remote gas supply with the purchase of a single hose and filter. To light the unit, simply push and rotate the knob. The built-in silent electric ignition will take care of the rest. With the Oxygen Depletion Sensor (ODS) and accidental tip-over safety shut-off, you can be sure that you will enjoy years of comfortable indoor safe heat.
