Only properly trained and qualified installers should install this appliance. The warranty may be voided due
to improper installation or installation by a
General Instructions
Do not use substitute materials.
Use only parts certified with the appliance.
•This appliance must be installed by a state qualified or licensed contractor. It is the responsibility of the person having the water heater installed to ensure the installing contractor has proper licenses and permits for installing water heaters in your location. It is highly recommended that installers attend a product knowledge class to ensure customer satisfaction and warranty coverage. Failure to comply with state and local codes pertaining to water heater installations may void the warranty.
•This appliance is not to be installed indoors.
•Aqualified installer or service technician should install the appliance, inspect it, and leak test it before use.
•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.
•The appliance, when installed, must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Code, ANSI/ NFPA 70, or the Canadian Electrical Code, CSA C22.1.
•The appliance and its appliance main gas valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psi (3.5 kPa) (13.84 in W.C.).
•The appliance must be isolated from the gas supply piping system by closing its individual manual shutoffvalve during any pressure testing of the gas supply piping system at test pressures equal to or greater than 1/2 psi (3.5 kPa) (13.84 in W.C.).
•The appliance should be located in an area where
water leakage of the unit or connections will not result in
damage to the area adjacent to the appliance or to lower floors of the structure. When such locations cannot be
avoided, it is recommended that a suitable metal drain pan, adequately drained, be installed under the appliance. The pan must not restrict combustion air flow.
•The flow of combustion and ventilation air shall not be obstructed.
•This appliance is not suitable for use in an application such as a pool or spa heater that uses chemically treated water. (This appliance is suitable for filling large or whirlpool bath tubs with potable water.)
It is highly recommended that all installers attend a product knowledge class.
•As water is heated, it expands (thermal expansion). In a dosed system, the volume of water will grow. As the volume of water grows, there will be a corresponding increase in water pressure due to thermal expansion.Thermal expansion can cause premature tank failure (leakage). This type of failure is not covered under the limited warranty. Thermal expansion can also cause intermittent pressure relief valve operation: water discharged from the valve due to excessive pressure build up. The pressure relief valve is not intended for the constant relief of thermal expansion. This condition is not covered under the limited warranty. A
•Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance.
•Keep the air intake location free of chemicals such as chlorine or bleach that produce fumes. These fumes can damage components and reduce the life of your appliance.
