INSTALLATION INSTRUCTIONS
Final Installation Checklist
Location
• The water heater is not subject to corrosive compounds in the air. .........................................................................................................
• The water supply does not contain chemicals or exceeds total hardness that will damage the heat exchanger. ......................................
• Clearances from the water heater unit are met.. ......................................................................................................................................
• Clearances from the vent termination / air intake are met.. ......................................................................................................................
Venting
• 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.. ...........................................................................................
• Verify that the vent system does not exceed the maximum length for the number of elbows used.. .......................................................
• Verify that switch # 1 in the SW1 DIP switch (tan switches) has been adjusted for vent length, if necessary.
Refer to the section on Maximum Vent Length.. ......................................................................................................................................
Piping
• Purge the water line of all debris and air by closing the hot isolation valve and opening the cold isolation valve and its drain.
Debris will damage the water heater. Use a bucket or hose, if necessary.. ..............................................................................................
• Ensure that hot and cold water lines are not crossed to the unit and are leak-free.. ................................................................................
• A manual gas control valve has been placed in the gas line to the water heater.. ....................................................................................
• Ensure that a pressure-relief valve is installed with a rating that exceeds the BTU input of the water heater model.
Refer to the rating plate on the side of the water heater for BTU input.. ..................................................................................................
• Clean the inlet water filter by closing the cold and hot water inlet isolation (shut-off) valves. Put a bucket under the filter
at the bottom of the water heater to catch any water that is contained inside the unit. Unscrew the water filter. Rinse the
filter to remove any debris. Install the filter and open the isolation valves.. .............................................................................................
• Check the gas lines and connections for leaks.. .......................................................................................................................................
Power and Gas Supply
• Confirm that the gas inlet pressure is within limits.. ................................................................................................................................
• Confirm that the water heater is rated for the gas type supplied.. ............................................................................................................
• Confirm that the electricity is supplied from a 120 VAC, 60 Hz power source, is in a properly grounded circuit, and turned on.. ...........
• Verify the temperature controller is functioning properly.. .......................................................................................................................
• Verify that switches # 2 and # 3 in the SW1 DIP switch (tan switches) is set correctly for your altitude.. ...............................................
• 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.. .................................................................................................................................................................
General
• If the water heater is not needed for immediate use, then drain the water from the heat exchanger.. .....................................................
• Install the front panel.. .............................................................................................................................................................................
• 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.. ............................................
• 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.. ..................................
• Inform the consumer if the isolation valves are not installed or if a water softening system is not installed.. .........................................
• Leave the entire manual taped to the water heater or give it directly to the consumer.. ...........................................................................
