INSTALLATION INSTRUCTIONS
Only properly trained and qualified installers should
install this appliance. The warranty may be voided due
to improper installation or installation by a non-qualified
installer. It is highly recommended that all installers attend a
product knowledge class.
General Instructions
A WARNING
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 outdoors.
A qualified 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, CSAB149.1.
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/NFPA70, 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 shutoff
valve 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.)
• As water is heated, it expands (thermal expansion). In
a closed 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 properly-sized thermal expansion tank should be
installed on all closed systems to control the harmful
effects of thermal expansion. Contact a plumbing service
agency or your retail supplier regarding the installation
of a thermal expansion tank. NOTE: Reference Figures
3-6 to see if your installation recommends the use of a
thermal expansion tank.
• 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.
