Dayton Nozzles are used to vent and exhaust fumes generated from low-profile gas heaters fixated on walls or ceilings. They direct the flow of hot air in desired direction. These units are made from durable steel and are bent at an angle to mount directly over the gas heaters. Choose from a wide range of these gas heater nozzles, available in 0, 30, 60 and 90 degrees bent angle variants on Raptor Supplies.
