Description
Note: ProMax name is now ProLine.

The ProLine® 400/401 Series gas water heater is designed to deliver an economical performance that can lower your energy bills and also provide long-lasting value. Featuring a 50-gallon tank and a 40,000 BTU gas burner, the GCRL-50 Standard Vent delivers a first hour rating of 93 gallons and a recovery rate of 41 gallons per hour. With an 0.60 Energy Factor, this water heater is not ENERGY STAR® qualified. It carries a 6-year limited tank warranty, and meets Low NOx emission requirements.

Features:
  • INTELLIGENT CONTROL LOGIC
    • The internal microprocessor provides enhanced operating parameters and tighter differentials for precise sensing and faster heating response to optimize performance.
    • Uses a thermopile to generate the power needed to operate the electronic gas control without requiring an external power source.
    • The electronic gas control incorporates an LED status indicator that monitors system operation and service diagnostics.
    • *Not available on 60,000 BTU input models (GCRX-50 and GCRX-55).
  • GREEN CHOICE GAS BURNER
      • Patented eco-friendly burner design reduces NOx emissions by up to 33% and complies with Low- NOx emission requirements of less than 40 ng/J.
    • DYNACLEAN DIFFUSER DIP TUBE
      • Reduces lime and sediment buildup and maximizes hot water output. Made from long-lasting PEX cross-linked polymer.
    • COREGARD ANODE ROD
      • Our anode rods have a stainless steel core that extends the life of the anode rod allowing superior tank protection far longer than standard anode rods.
    • PUSH-BUTTON PIEZO IGNITOR
      • Makes lighting the pilot fast and easy with one hand push-button spark ignition.
    • HEAT TRAP NIPPLES
      • Factory-installed for faster installation.
    • BLUE DIAMOND GLASS COATING
      • Provides superior corrosion resistance compared to industry standard glass lining.
    • ENHANCED FLOW BRASS DRAIN VALVE
      • Our residential water heaters have a solid brass, tamper resistant, enhanced flow, ball type, drain valve.
      • Uses a standard female hose fitting that allows for fast and easy draining during maintenance.
      • Designed for easy operation, this valve includes an integral screwdriver slot that features a 1/4 turn (open/close) radius, which not only permits full straight-through water flow but also a quick and positive shut off.
    • CODE COMPLIANCE
      • Meets UBC, CEC and HUD National Codes.
      • Meets the thermal efficiency and standby loss requirements of the U. S. Department of Energy and current edition of ASHRAE/IENSA 90.1.
      • Complies with the Federal Energy Conservation Standards effective April 16, 2015, in accordance with the Energy Policy and Conservation Act, (EPCA), as amended.
    • HIGH ENERGY FACTORS
      • Eco-Friendly non-CFC foam insulation, external heat traps and specially designed combustion chamber combine to produce a high Energy Factor for maximum savings on operating costs.
    • CSA CERTIFIED AND ASME RATED
    • T&P RELIEF VALVE
    • MAXIMUM HYDROSTATIC WORKING PRESSURE 150 PSI
    • DESIGN-CERTIFIED BY CSA INTERNATIONAL
      • Certified at 300 PSI test pressure and 150 PSI working pressure. Listed according to ANSI Z21.10.1-CSA 4.1 standards governing storage tank-type water heaters.

      A. O. Smith's new gas residential water heaters meet the requirements for the new 2015 NAECA minimum efficiency regulations.
