The Lava Heat Italia Opus Lite Liquid Propane Gas Patio Heater has a fully-adjustable 3-foot flame encased in a shatter-proof Borosilicate glass tube. The glass allows for 360 degrees of heat distribution in a 5-foot radius, while the fire can be viewed from any angle. The protective steel grill never gets hot and puts a safe distance between you and the flame. Unlike a traditional seasonal patio heater the Opus Lite can be used all year-long in the comfort of your outdoor environment. It stands 6 feet tall and can be started with the "Easy Start" pilot light ignition. The Opus Lite patio heater can be operated for up to 10 hours with a 20 lb. propane tank (LP tank not included). The built-in Safety-Tilt switch shuts the unit off if it tilts or falls over.
