The patented direct ignition system, never before seen on an outdoor gas radiant heater, ensures a reliable start and effective operation, even in winds of up to 12km/h. The Tungsten Smart-Heat comes in an attractive black finish. Its universal bracket makes it easy to upgrade from 3-burners to 5-burners with no additional plumbing or wiring. Multiple units can be switched on and off simultaneously from a single remote-located switch. The Tungsten Smart-Heat units are wind resistant to 8 mph. The Tungsten Smart-Heat can be run on propane and natural gas. Should the gas heater not re-ignite for any reason, the integrated “Flame Failure Safety Shut-off Control” turns the heater off immediately. Available in two sizes 300 series (26,000 BTU’s) and 500 series (43,000.).
