INSTALLATION CHECKLIST
• Ensure 120 Volts A.C. is connected to the unit and that
the circuit is turned on.
• Verify the gas system is functioning correctly by
connecting your manometer to the gas pressure test port
on the unit (see page 11). Operate all gas appliances in
the facility. The inlet gas pressure on the unit MUST NOT
DROP BELOW that listed on the unit rating plate for the
gas type being used. A manometer can be used to check
the pressure.

screen.
• Inspect HOT (outlet) and COLD (inlet) water lines to ensure
they have not been crossed and are leak-free.
• Ensure the manual gas valve packaged with the water
heater is installed in the gas supply line (see page 10).
• Ensure the controller is installed and functioning.
Instruct the consumer on how to operate the controller.
Instructions are always supplied in the Owner’s Manual
(see page 18). A typical water temperature set point
is 120 degrees.
