LIGHT-DUTY COMMERCIAL GAS NON-DAMPERED WATER HEATER

• 1-Year Limited Warranty* on Tank
  Heavy-gauge steel is automatically formed, rolled and welded to assure a continuous seam for glass lining. Each tank is double tested to ensure quality.
• 1-Year Limited Warranty* on Parts
• 2" of Polyurethane Foam - Non-CFC
  Foam insulation saves fuel by retarding heat loss.
• Fused Ceramic Shield^TM
  Applied under pressure and fired at 1600^oF to completely cover the tank interior. This provides a tough interior surface for storage tanks and maximum protection against the wearing effects of high-volume and high-temperature hot water.
• Anode Rod
  Promotes longer tank life through even distribution for protection against corrosion of tank interior.
• Factory-Installed Temperature and Pressure Relief Valve
• Recoveries
  First-hour delivery ratings are based on thermal efficiencies of 80%. Recovery figures shown on water heater ratings plates are based on (75%) recovery efficiency in compliance with (AGA) ANSI Z-21.10 requirements.
• Design Certified
  By the American Gas Association and Canadian Gas Association for up to 180^oF as an automatic storage heater in compliance with AGA ANSI Z-21.10.3 test requirements (CG32-100T88-4N) and CG32-75T75. 50 gallon model is certified in compliance with ANSI-Z21.10.1
• California (CEC) and New York
  Energy requirements met or exceeded.
• Builder Block Concept
  Enables multiple heaters of equal size and input manifolded together to operate as one total system. This concept allows the system to be maintained and serviced without shutting down the complete system.
