This versatile forced-air convection heater brings you peace of mind and years of comfortable, safe heat. It uses a high-velocity electric fan to pull cool air into the rear of the unit and across a heat exchanger, then forces warm air out. The thermostatically controlled unit features a spark ignition with self-diagnostic control module. Ideal for environments where ceiling heights do not allow for infrared heaters to be used, the low-profile design requires just an 8' minimum ceiling height and 1' mounting clearance. Power exhaust allows for vertical or horizontal venting; please check local codes and restrictions. Heatstar Natural Gas Unit Heater with NG to LP Conversion Kit
