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 13). 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.
• Make sure you have cleaned the COLD water inlet filter
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 12).
• 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 22). A typical water temperature set point
is 120 degrees.
• Explain to the customer the importance of never
blocking the vent ducting, intake and exhaust.
Never store anything around the vent exhaust.
• Ensure you have used the correct venting products
for the model installed and that you have completely
followed the venting installation instructions
(see pages 19–20).
• Ensure the condensate collector drain on the unit
is installed to allow condensation to drain away from
the water heater to a proper drain source (see page 8).
• The vent system should not exceed the maximum length
for the number of elbows used. Refer to the venting
maximum length chart on page 19. Apply the vent
temperature caution label to the vent terminal located
