NATURAL GAS AND LIQUIEFIED PRETROLEUM MODELS
Both LP and natural gas have an odorant added to aid in the
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 NG, 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 utilizing LP gas are different from natural gas models.
A natural gas water heater will not function safely on LP gas and vice
versa

No attempt should ever be made to convert the water heater from
NG to LP gas. To avoid possible equipment damage, personal injury,
or fire, do not connect the water heater to a fuel type not in
accordance with the data plate.

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 and NG applications and their
installation should be in accordance with the detector manufacturer's
recommendations and/or local laws, rules, regulations or customs.
