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.
DANGER!
LIqUEFIEDPETROLEUM(LPPROPANE)
ANDNATURALGASMODELS
● 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 natural
gas 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 unit
data plate. LP for LP units. Natural gas
for natural gas units. These units are not
certified for any other fuel type.
● LP appliances should not be installed
below grade (for example, in a basement)
if such installation is prohibited by
federal, state and/or local laws, rules,
regulations or customs.
● 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
& natural gas applications and their
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
detectors, etc., be used to detect leaks in
gas applications.
!
DANGER: If a gas leak is present or
suspected:
● Donotattempt to find the cause yourself.
● Donot try to light any appliance.
● Donot touch any electrical switch.
● Donot use any phone in your building.
● Leave the house immediately and make
sure your family and pets leave also.
● Leave the doors open for ventilation
and contact the gas supplier, a qualified
service agency or the fire department.
● Stay away from the house (or building)
until the service call has been made, the
leak is corrected and a qualified agency
has determined the area to be safe.

recommended that a suitable catch pan,
adequately drained, must be installed under
the water heater.
The pan must not restrict air flow to the
combustion air inlet openings (perforation
openings) located around the lower perimeter of
the water heater.
