The Sterling XF250A1NS111 Tubular gas-fired unit heaters offer a highly efficient, extremely durable alternative to the traditional clam shell design. These units combine the latest tubular heat exchanger and inshot burner technology with the quality and reliability you have come to know from Sterling.
Standard energy saving features like the direct spark ignition and power venting reduce standby losses and offer improved seasonal efficiency. Tubular units certified by ETL as providing 83% thermal (combustion) efficiency.
The Sterling tubular heat exchanger has been designed to provide maximum and uniform heat transfer. The low pressure drop associated with this design enables heated air to be evenly distributed to the conditioned space. This curved, non-welded serpentine design experiences less thermally induced stress making it highly durable for significantly longer service life. All Sterling tubular heat exchangers are constructed of heavy duty 20-gauge aluminized steel.
Sterling Tubular units utilize a direct spark pilotless ignition of the burner, providing fast heat delivery. This highly reliable and efficient ignition system incorporates an integrated electronic control board to regulate the system sequence of operation, including an onboard LED indicator for simple troubleshooting.
The Sterling Tubular unit heaters are ETL certified in accordance with categories I and III venting requirements. This certification allows units to be vented both vertically and horizontally using either singlewall or doublewall venting materials. This venting flexibility of the unit heater makes installation easier and more cost effective by allowing the installer to utilize existing venting components.
Sterling warranties the heat exchanger, flue collector and burners of each unit heater to be free from defects in materials and workmanship for a period of 10 years from the date of manufacture.
