INSTALLATION INSTRUCTIONS
Installation CheckList
• The water heater is not exposed to corrosive compounds in the air. ........................................................................................................
• The water heater location complies with the clearances. ..........................................................................................................................
• The water supply does not contain chemicals or exceed total hardness that will damage the heat exchanger. ........................................
• Ensure the water heater and its water lines are protected from freezing. Damage due to freezing is not covered by the warranty. ..........
• Confirm that the electricity is supplied from a 120 VAC, 60 Hz power source, is in a properly grounded circuit, and turned on. .............
• The installation must conform with local codes or, in the absence of local codes, with the National Fuel Gas Code,
ANSI Z223.1/NFPA 54, or the Natural Gas and Propane Installation Code, CSA B149.1. ..........................................................................
• Verify proper clearances around the vents and air intakes. .......................................................................................................................
• Ensure that the Combustion Air Requirements are followed that will provide sufficient combustion air for the appliance. ......................
• Ensure you have used the correct venting products for the model installed and that you have completely followed the venting
manufacturer's installation instructions and these installation instructions. .............................................................................................
• The water heater must be vented vertically to the outside of the building or structure. ............................................................................
• Purge the water line of all debris. Debris will damage the water heater. Use a bucket or hose, if necessary. ...........................................
• Ensure the water heater is vented in accordance with National Fuel Gas Code, ANSI Z223.1/NFPA 54 - latest edition and the
requirements of state or local codes. ........................................................................................................................................................
• Ensure that hot and cold water lines are not crossed to the unit and are leak-free. ..................................................................................
• Clean the inlet water filter by first powering OFF the water heater. Remove the lower enclosure. Drain and relieve the pressure
from the system. Remove and clean the filter of any debris that may reduce water flow. Once clean, replace the filter. Close the
drain valve and pressurize the system. Power the unit back ON and set desired temperature. For more information on cleaning
the filter, please see page 26 section C. ....................................................................................................................................................
• Ensure that the temperature/pressure relief valve is installed. ..................................................................................................................
• Check for proper water pressure to the water heater. Minimum water pressure is 20 psi. A water pressure of 30-50 psi is
recommended for maximum performance. ..............................................................................................................................................
• A manual gas control valve has been placed in the gas line to the water heater. ......................................................................................
• Check the gas lines and connections for leaks. .........................................................................................................................................
• Confirm that the gas inlet pressure is within limits. ..................................................................................................................................
• Confirm that the water heater is rated for the gas type supplied. ..............................................................................................................
• An extension cord or an adapter plug has not been used with the water heater. ......................................................................................
• Verify the system is functioning correctly by connecting your manometer to the gas pressure test port on the water heater.
Operate all gas appliances in the home or facility at high fire. The inlet gas pressure at the water heater must not drop below
that listed on the rating plate. ...................................................................................................................................................................
• Ensure the lower enclosure is installed. ....................................................................................................................................................
• Explain to the customer the importance of not blocking the vent termination or air intake. ......................................................................
• Explain to the customer the operation of the water heater, safety guidelines, maintenance, and warranty. ..............................................
