General The installation must conform with these instructions and the local code authority having jurisdiction and the requirements of the power company.

  • Page 9: Water Line Connections

    For safe operation of the water heater, the temperature and pressure relief valve must not be removed from its designated opening nor plugged. The temperature-pressure relief valve must be installed directly into the fitting of the water heater designed for the relief valve. Install discharge piping so that any discharge will exit only within 6 inches (15.2 cm) above, or at any distance below the structural floor.

  • Page 16: Temperature Regulation

    hIGh teMperature lIMIt controls (eco) This water heater is equipped with an ECO (energy cut off) non adjustable high temperature limit control. An ECO is a normally closed switch that opens (activates) on a rise in temperature. If the ECO switch contacts open (activate) due to abnormally high water temperatures the control system will lock-out and disable further heating element operation.
