Natural Gas Safety
DANGERS:
• Never attempt to convert the water heater from natural
gas to LP or vice versa. The water heater must only use
the fuel type in accordance with listing on data plate—
natural gas for natural gas units. Any other fuel usage
will result in death or serious personal injury from fire
and/or explosion. This water heater is not certified for
any other fuel type.
• Both natural gas and propane (LP) 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 natural gas or LP, 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.
• Water heaters using LP gas are different from natural
gas models. A natural gas water heater will not
function safely on LP.
• 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 also sniff
near the floor.
• Gas detectors are recommended in LP and natural
gas applications and their installation should be
in accordance with the detector manufacturer's
recommendations and/or local laws, rules, regulations,
or customs.
• Combustible materials, such as clothing, solvents,
cleaning materials, or flammable liquids, must not be
placed in the vicinity of the water heater.
• If a gas leak is present or suspected:
– DO NOT attempt to find the cause yourself.
– Never use an open flame to test for gas leaks. The gas can
ignite resulting in death, personal injury, or property damage.
– Follow the steps listed under "What to Do If You Smell Gas"
found on the front cover of this manual.
IMPORTANT SAFETY INFORMATION
WARNINGS:
• The installation of gas piping must comply with local
utility company requirements and/or in the absence of
local codes, use the latest edition of National Fuel Gas
Code (NFGC), ANSI Z223.1/NFPA 54, or CAN/CSA B149.1,
Natural Gas and Propane Installation Code.
• If inlet gas pressure is out of allowable range [4.0" w.c.
(1.0kPa) – 10.5" w.c. (2.6kPa)] for Natural Gas, a gas
pressure regulator must be installed to maintain the
allowable inlet gas pressure.
• Should overheating occur or the gas supply fail to shut
off, turn off the manual gas control valve to the water
heater.
CAUTIONS:
• DO NOT attempt repair of electrical wiring, gas piping,
remote control, burners, vent connectors, or other safety
devices. Refer repairs to qualified service personnel.
• Turn off the manual gas 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.
• DO NOT turn on the water heater unless the water and
gas supplies are completely opened.
