Installation Checklist

This unit has several new features. Before installing, read the Installation Manual and follow all safety warnings and installation instructions.

  1. Venting

    Make sure the Intake and Exhaust vent pipes do not exceed the lengths listed in the Installation Manual. Plastic elbows are the equivalent of five feet of straight pipe. Make sure the debris screen has been removed from the Intake vent If the unit will be Direct Vented (outside air).

  2. Gas Supply

    The unit's Data Plate lists the BTU input and minimum gas pressure requirements. Make sure the gas pipe size and length is correct for the BTU input listed on Data Plate Make sure the gas pressure regulator is adequate for the BTU input listed on Data Plate. Check gas supply pressure with a gas pressure gauge. See Installation Manual for details.

  3. Condensate Drain

    Make sure the Condensate Drain pipe slopes to an adequate drain. See Installation Manual for construction details.

  4. Electrical Supply

    Ensure that the electrical power supply has been installed according to the instructions in the Installation Manual. This unit must be properly grounded.

  5. Enable/Disable Switch

    The switch in front of the LCD display is an "Enable/Disable" switch. It does not turn power off to the main circuit board. If the LCD display says "Water Heater Disabled," press the Enable switch on the front of the unit to allow water heater to operate.
