Features/Benefits

  • Smart System™ Operating Control and Con-X-Us® Remote Connect Capable
  • FTXL Offers Best-In-Class AHRI Thermal Efficiency and Footprints, Plus Remote Connectivity that Puts the Smart System™ Control at Your Fingertips, Anywhere
  • Reduce Installation Cost with Variable Flow Technology-FTXL can Operate over a Wide Range of Flow Rates with Very Low Pressure Drop
  • This Permits Installation of a Full Flow System Eliminating the Time and Materials Cost of Primary/Secondary Piping and Pumps Needed to Maintain Flow in a Water Tube Boiler
  • Variable Flow also Makes FTXL More Flexible at Handling Frequent Fluctuations in the System Flow Rate
  • Smooth-Running, Modulating Combustion-FTXL Boilers have a Top-Mounted, Micrometal Fiber Burner with a Blower/Gas Valve Assembly that Drives Heat Energy Downward, Through Stainless Steel Fire Tubes, With Exhaust Venting through the Bottom of the Unit. a Modulating System Runs Smoothly and Efficiently, Without Frequent On/Off Cycling
  • Minimum Supply Pressure, Installer-Friendly-FTXL Operates with Supply Gas Pressure as Low as 4 Inch Water Column
  • Negative Regulation Draws Gas into a Pre-Mix Combustion System, Instead of Relying on Utility Pressure through the Gas Valve
  • The Result is Steady Operation in Low Gas Pressure Systems or When Peak Demand Occurs on Gas Supply
  • Automatic Fan Speed Control Fine-Tunes the Correct Fuel/Air Ratio Entering the Burner, Providing Superior Combustion Throughout the Entire Operating Range
  • Wireless Outdoor Sensor
  • Energy Star® Rated
  • Made in USA
