Testing and Certifications

Testing and Certifications

 N/A
  • American Standard® gas water heaters are certified at 300 PSI test pressure and for 150 PSI working pressure. CSA® certified to meet NSF/ANSI 5 Standards
  • Tested and listed with CSA® International in accordance with ANSI Z21.10.3-CSA® 4.3 for up to 180 ºF operation as an automatic storage and/or automatic circulating tank heater. Meets ASHRAE Standard 90.1-1999

Features

Features

 N/A
  • Heavy Gauge Steel Tank incorporating only seven internal flue tubes resulting in fewer critical welds to yield added years of service.
  • ASME Construction Model available.
  • Inner tank glass-lined with Dura-Glas™ and fired at 1600 ºF for optimum protection from the effects of corrosion.
  • R-8.3 non-CFC foam insulated to save energy and reduce fuel costs by maximizing heat retention.
  • Four anode rods to ensure maximum tank life.
  • Self-Cleaning turbulence inducing cold water inlet-tube engineered to diminish hard water area sediment deposits.
  • Full size hand-hole cleanout for eased tank inspection and/or removal of sediment deposits.
  • Electronic direct-spark ignition system saves fuel by eliminating the need for a standby gas pilot.
  • Automatic motorized flue damper reduces tank heat loss during standby periods for lowest operating costs.
  • Fully adjustable 24-volt controls provide temperature settings to 180 ºF. When installed with a mixing valve, the D-100-250-AS can deliver 180 ºF sanitizing and 140 ºF general purpose hot water simultaneously.
  • Factory installed energy cut-off system and pressure/temperature valve.
  • Top 1-1/2", 2" rear and 2" front water connections for universal replacements, connection to circulating lines and eased multiple heater or storage tank installations.
