The OPUS G7 - 51,000 BTU Natural Gas Commercial Flame Patio Heater: All the great features of the Lava 2G with a classic look! Hidden inside the Lava Heat Opuss traditional cylindrical design is the same cutting-edge technology found in the Lava Heat 2G models just in a shorter frame. Originally designed and engineered in Italy by Mr. JR Zioni. The Opus 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 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 the one-button, "Easy-Start" infrared electric ignition on the front of the unit, and a universal infrared remote which can be used to turn multiple units on at the same time. With its standard protective and safe to touch outer grill, 304 Grade stainless steel construction and simple operation, the Opus 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 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 fully assembled and requires two D batteries. Your Opus can also be ordered with an optional wheel kit and a fitted protective cover. Available finishes: 304 Stainless Steel and Heritage Bronze.
