Ceramic Infrared Heating is the answer for spot or area heating and for total building heating needs. It is also ideal for the replacement of existing ceramic heaters. SunStar Ceramic Heaters heat like the sun by transferring radiant heat energy directly into the area to be heated and creating a warm comfort zone at the floor level. This extremely efficient method of heating can result in fuel savings of between 30% and 50% when compared to forced air convection heating.Capacities from 30,000 to 155,000 Btu hr Dimpled tile assembly design for increased radiant efficiency Design certified for angle mounting up to 30 degrees Equipped with 100% gas shut-off safety control Constructed of aluminized steel for corrosion resistance Aluminum reflectors designed to maximize radiant output Optional protective radiant screenApplications: Aircraft Hangars, Loading Docks, Fire Stations, Commercial Garages, Machine Shops, Tennis Courts, Maintenance Shops, Farm Buildings, Truck Service Areas Clearances to Combustibles (Mounted 30° Angle) Below: 129 Clearances to Combustibles (Mounted 30° Angle) Front: 65 Clearances to Combustibles (Mounted 30° Angle) Rear: 49 Clearances to Combustibles (Mounted 30° Angle) with Reflector Extension: 181 Clearances to Combustibles (Mounted Horizontally) Below: 129 Clearances to Combustibles (Mounted Horizontally) Ceiling: 65 Clearances to Combustibles (Mounted Horizontally) Sides: 49 Clearances to Combustibles (Mounted Horizontally) with Reflector Extension: 181 Collection: Starglo Fuel Type: Liquid Propane, Natural Gas Heater Type: Infrared Liquid Propane BTUs: 100,000 Liquid Propane Burner Pressure (Water Column): 10 Liquid Propane Supply Pressure (Water Column): 11-14 Minimum Mounting Height: 15' Natural Gas BTUs: 100,000 Natural Gas Burner Pressure (Water Column): 6 Natural Gas Supply Pressure (Water Column): 7-14 No. of Burners: 3
