IMPORTANT SAFETY INFORMATION
READ ALL INSTRUCTIONS BEFORE USING
Be sure to read and understand the entire Use and Care Manual before attempting to install or
operate this water heater. It may save you time and money. Pay particular attention to the Safety
Instructions. Failure to follow these warnings could result in serious bodily injury or death. Should
you have problems understanding the instructions in this manual, or have any questions, STOP,
and get help from a qualified service technician, or the local gas utility.

! DANGER!
INSTALL THE DRAFT HOOD AND PROPERLY VENT THE
WATER HEATER…
Failure to install the draft hood and properly vent the water heater to the outdoors
as outlined in the Venting Section of the Installation Instructions in this manual can
result in unsafe operation of the water heater. To avoid the risk of fire, explosion,
or asphyxiation from carbon monoxide, never operate this water heater unless it is
properly vented and has an adequate air supply for proper operation. Be sure to
inspect the vent system for proper installation at initial start-up; and at least annually
thereafter. Refer to the Care and Cleaning section of this manual for more information
regarding vent system inspection.

! WARNING!
Gasoline, as well as other flammable materials and liquids which include, but are not
limited to (adhesives, solvents, paint thinners etc.), and the vapors they produce are
extremely dangerous. DO NOT handle, use or store gasoline or other flammable or
combustible materials anywhere near or in the vicinity of a water heater or any other
appliance. Be sure to read and follow warning label pictured below and other labels on
the water heater, as well as the warnings printed in this manual. Failure to do so can
result in property damage, bodily injury or death.

! WARNING

FLAMMABLES Flammable Vapors

FIRE AND EXPLOSION HAZARD

Can result in serious injury or death.
! Do not store or use gasoline or other flammable vapors and liquids
in the vicinity of this or any other appliance. Storage of or use of gasoline

WATER TEMPERATURE SETTING
Safety and energy conservation are factors to be considered when selecting the water
temperature setting of a water heater’s gas control. Water temperatures above 125°F
can cause severe burns or death from scalding. Be sure to read and follow the warnings
outlined on the label pictured below. This label is also located on the water heater.

 ! DANGER!
LIQUEFIED PETROLEUM (LP)
AND NATURAL GAS MODELS
LP and Natural gas have an odorant added to aid in detecting a gas leak. Some people may
not physically be able to smell or recognize this odorant. If you are unsure or unfamiliar
with the smell of LP or natural gas, ask the gas supplier. Other conditions, such as “odorant
fade”, which causes the odorant to diminish in intensity, can also hide or camouflage a gas
leak.

● LP gas must be used with great caution.
It is heavier than air and will collect first
in lower areas making it hard to detect at
nose level.
● Before attempting to light the water
heater, make sure to look and smell for
gas leaks. Use a soapy solution to check
all gas fittings and connections. Bubbling
at a connection indicates a leak that must
be corrected. When smelling to detect a
gas leak, be sure to sniff near the floor
also.
● Gas detectors are recommended in LP

installation should be in accordance
with the detector manufacturer’s
recommendations and/or local laws,
rules, regulations or customs.
● It is recommended that more than one
method, such as soapy solution, gas

gas applications.

IMPORTANT SAFETY INFORMATION
READ ALL INSTRUCTIONS BEFORE USING
! WARNING!
For your safety, the information in this manual must be followed to minimize the risk of fire
or explosion, electric shock, or to prevent property damage, personal injury, or loss of life.

FOR INSTALLATIONS IN THE STATE OF CALIFORNIA

California Law requires that residential water heaters must be braced, anchored or
strapped to resist falling or horizontal displacement due to earthquake motions. For
residential water heaters up to 52-gallon capacity, a brochure with generic earthquake
bracing instructions can be obtained from: Office of the State Architect, 1102 Q Street,
Suite 5100, Sacramento, CA 95814 or you may call 916-445-8100 or ask a water heater
dealer.
However, applicable local codes shall govern installation. For residential water heaters of
a capacity greater than 52 gallons, consult the local building jurisdiction for acceptable
bracing procedures.

SAFETY PRECAUTIONS
Have the installer show you the location of the gas shut-off valve and how to shut it off
if necessary. Turn off the manual shut-off valve if the water heater has been subjected to
overheating, fire, flood, physical damage or if the gas supply fails to shut off.

Operating the water heater
CAUTION: Hydrogen gas can be produced in a hot water system served by this water heater that has not been used
for a long period of time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE!! To
dissipate such gas and to reduce risk of injury, it is recommended that the hot water faucet be opened for several
minutes at the kitchen sink before using any electrical appliance connected to the hot water system. If hydrogen is
present, there will be an unusual sound such as air escaping through the pipe as the water begins to flow. DO NOT
smoke or use an open flame near the faucet at the time it is open.
