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, or [8.0”
w.c. (2.0kPa) – 13.0” w.c. (3.2kPa)] for LP 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 the repair of any 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.
Natural Gas and Liquefied Petroleum 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 the listing on the
data plate—natural gas for natural gas units and LP
for LP 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 and vice versa.
• LP 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 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.
