All 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. When equipped with a mixing valve, it will supply 180 deg F (82 deg C) sanitizing and lower temperature general purpose hot water simultaneously. These models can be used either as a single unit or in multiples connected in series or parallel (recommended).
