The Lava Heat Italia Ember Collapsible Liquid Propane Gas Patio Heater sports a classic look that belies its high-tech interior. The Ember is unique in that it is able to collapse from 6 feet to 4 feet for easy storage. Borosilicate glass allows for 360 degrees of heat distribution in a 5-foot radius, while the fire can be viewed from any angle. Its proprietary spiral flame adds elegance to the warmth and ambience generated by the natural flame. The protective steel grill is one single piece that never gets hot and puts a safe distance between you and the flame. The Ember patio heater can be operated for up to 10 hours with a 20 lb. propane tank (LP tank not included). It has solid steel construction, weighted base and an "Easy Start? electronic ignition. The built-in Safety-Tilt switch shuts the unit off if it tilts or falls over.
