The OPUS Lite G7 - 51,000 BTU Propane Residential Flame Patio Heater: All the beautiful design of the original OPUS G7 model with a simple twist! Hidden inside the Opus Lite"s traditional cylindrical design is the same cutting-edge technology found in the Lava Lite Z7 model just in a shorter frame. Originally designed and engineered in Italy by Mr. JR Zioni. The Opus Lite has a fully-adjustable 3-foot flame, which is encased in a shatter-proof Borosilicate glass tube and puts out an impressive 51,000 BTUs. The Borosilicate glass is a material similar to glass bake ware that withstands both extreme heat and cold and can be used with the high setting for hours even during rain, hail or snow. The glass also allows for 360 degrees of heat distribution in a 36 square foot radius, while the fire can be viewed from any angle. Unlike a traditional seasonal patio heater the OPUS Lite G7 can be utilized all year-long in the comfort of your outdoor environment. The Opus stands 6.5 ft tall and can be started with a manual "Easy-Start" electronic ignition on the front of the unit. With its standard protective and safe to touch outer grill, solid steel construction and simple operation, the Opus Lite G7 is a premium outdoor heater built for years of uninterrupted use and enjoyment. The built-in Safety Tilt switch shuts the unit off if it tilts or falls over. The Opus Lite G7 Natural Gas model can provide constant use and is also more energy efficient, making it 10% the actual operational cost when compared to its propane counterpart. Lava Heat Italia also includes a 10 ft. natural gas quick-disconnect hose as a free added value. This unit comes partially assembled and requires one AA battery. The unit can be used for up to 10 hours with a 20 lb. propane tank. Your Opus Lite can also be ordered with an optional wheel kit and a fitted protective cover. Available finishes: New Gun Metal and Heritage Bronze.
