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 indoors.
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/NFPA54, 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, CSAC22.1.
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 4-7
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.
