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!
LIqUEFIED.PETROLEUM.(LP.-.PROPANE.OR.BUTANE).
AND.NATURAL.GAS.MODELS
● 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.

Installing the water heater.
Combustion and Ventilation Air
Proper operation of the water heater
requires air for combustion and
ventilation. Provisions for combustion
and ventilation air must comply with
referenced codes and standards.
When installed in a closet, DO NOT block
or obstruct any of the combustion air inlet
openings located around the perimeter
of the water heater. A minimum of 1” is
required between these combustion air inlet
openings and any obstruction.
NOTICE: If the water heater is installed
in an unconfined space within a building
of conventional frame, masonry or metal
construction, infiltration air is normally
adequate for proper combustion and
ventilation. If the water heater is installed in
a confined space, provisions for combustion
and ventilation air must be made.

Installing the water heater.
A new combination temperature and pressure relief valve, complying with the Standard for Relief Valves
and Automatic Gas Shut-Off Devices for Hot Water Supply Systems, ANSI Z21.22/CSA 4.6, is supplied
and must remain in the opening provided and marked for the purpose on the water heater. No valve
of any type should be installed between the relief valve and the tank. Local codes shall govern the
installation of relief valves.
Relief Valve
The.pressure.rating.of.the.relief.valve.
must.not.exceed.150.psi.(1,034.kPa),.the.
maximum.working.pressure.of.the.water.

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.

block or obstruct any of the combustion air
inlet openings located around the perimeter
of the water heater. A minimum of 1” is
required between these combustion air inlet
openings and any obstruction.
Routine Preventative Maintenance
Properly.maintained,.your.water.heater.
will.provide.years.of.dependable.trouble-
free.service.
It.is.recommended.that.a.periodic.
inspection.of.the.gas.control.(thermostat),.
burner,.relief.valve,.internal.flue-way.and.
venting.system.should.be.made.by.service.
personnel.qualified.in.gas.appliance.repair
It.is.suggested.that.a.routine.preventative.
maintenance.program.be.established.and.
followed.by.the.user
Periodically,.lift.and.release.the.lever.
handle.on.the.temperature.pressure.relief.
valve,.located.near.the.top.of.the.water.
heater,.to.make.certain.the.valve.operates.
freely.Allow.several.gallons.to.flush.
through.the.discharge.line.to.an.open.drain
NOTICE: If the temperature and
pressure relief valve on the hot water
heater discharges periodically, this
may be due to thermal expansion in a
closed water system. Contact the water
supplier or your plumbing contractor on
how to correct this. DO NOT plug the
relief valve outlet.
A.water.heater’s.tank.can.act.as.a.settling.
basin.for.solids.suspended.in.the.water.
It.is.therefore.not.uncommon.for.hard.
