Marketing InformationAll gas water heaters are certified at 300 psi test pressure (2068 kPa) and 150 psi working pressure (1034 kPa). All models are design certified by CSA international (formerly AGA/CGA), ANSI Z-21.10.3, for up to 180 deg F (82 deg C) application as an automatic storage heater and an automatic circulating tank heater. As an automatic storage heater, all models are complete, self-contained water heating systems. It needs no separate storage tank, pump, wiring or elaborate piping network.
