WARNING: Do not attempt to convert this water heater for use with a different type of gas other than the type
shown on the rating plate. Such conversion could result in hazardous operating conditions.
Leak Testing
The.water.heater.and.its.gas.connections.
must.be.leak.tested.at.normal.operating.
pressures.before.it.is.placed.in.operation .
...Turn.on.the.manual.gas.shut-off.
valve.near.the.water.heater .
...Use.a.soapy.water.solution.to.test.for.
leaks.at.all.connections.and.fittings ..
Bubbles.indicate.a.gas.leak.that.must.
be.corrected ..
The.factory.connections.to.the.gas.
control.(thermostat).should.also.be.leak.
tested.after.the.water.heater.is.placed.in.
operation .
High Altitude
Input.rating.of.this.water.heater.is.
based.on.sea.level.operation ...At.higher.
elevations.the.actual.input.rate.may.be.
lower.than.the.value.listed.on.the.rating.
label.due.to.the.derating.of.natural.gas.and.
LP.gas ...This.water.heater.can.be.installed.
at.elevation.up.to.2,000.feet.without.any.
change.or.modification .
For.installation.between.2,000.and.7,700.
feet,.refer.to.the.Venting.Information.
tables.on.page.13.and.14.for.maximum.
vent.lengths .
Installations.above.7,700.feet.are.not.
authorized .
Contact.the.local.gas.supplier.for.more.
information .
Pressure Testing the Gas Supply System
The.water.heater.and.its.manual.gas.
shut-off.valve.must.be.disconnected.from.
the.gas.supply.piping.system.during.any.
pressure.testing.of.that.system.at.
pressures.in.excess.of.3/8.psi.(10 .5”.w .c .).
for.natural.gas,.or.1/2.psi.(14”.w .c .).for.
LP.gas .
The.water.heater.must.be.isolated.from.
the.gas.piping.system.by.closing.the.
manual.gas.shut-off.valve.during.any.
pressure.testing.of.the.gas.supply.piping.
at.pressures.equal.to.or.less.than..
3/8.psi.(10 .5”.w .c .).for.natural.gas,.or..
1/2.psi.(14”.w .c .).for.LP.gas .
Gas Supply
The.branch.gas.supply.line.to.the.water.
heater.should.be.clean.1/2”.black.steel.
pipe.or.other.approved.gas.piping.
material .
A.ground.joint.union.or.ANSI.design.
certified.semi-rigid.or.flexible.gas.
appliance.connector.should.be.installed.
in.the.gas.line.close.to.the.water.heater ..
The.National.Fuel.Gas.Code.(NFGC).
mandates.a.manual.gas.shut-off.valve:.See.
(NFGC).for.complete.instructions .
If.flexible.connectors.are.used,.the.
maximum.length.shall.not.exceed.36”.
and.must.meet.the.requirements.in.ANSI.
Z21 .24-Connectors.for.Gas.Appliances .
If.lever.type.gas.shut-offs.are.used,.
they..shall.be.T-Handle.type .
Compound.used.on.the.threaded.joints.of.
the.gas.piping.must.be.of.the.type.resistant.
to.the.action.of.LP.gas ..Use.compound.
sparingly.on.male.threads.only ..
Where.a.sediment.trap.is.not.incorporated.
as.part.of.the.appliance,.a.sediment.trap.
shall.be.installed.downstream.of.the.
equipment.shutoff.valve.as.close.to.the.
inlet.of.the.appliance.as.practical.at.the.
time.of.the.appliance.installation ..The.
sediment.trap.shall.be.either.a.tee.fitting.
with.a.capped.nipple.in.the.bottom.outlet.
or.other.device.recognized.as.an.effective.
sediment.trap .
Do.not.use.excessive.force.(over.31 .5.ft.
lbs .).in.tightening.the.pipe.joint.at.the.gas.
control.(thermostat).inlet,.particularly.if.
teflon.pipe.compound.is.used,.as.the.valve..
body.may.be.damaged .
The.inlet.gas.pressure.to.the.water.heater.
must.not.exceed.10 .5”.w .c ..for.natural.gas,.
or.14”.w .c ..for.LP.gas ..For.purposes.of.
input.adjustment,.the.minimum.inlet.gas.
pressure.(with.main.burner.on).is.shown.
on.the.water.heater.rating.plate ..If.high.or.
low.gas.pressures.are.present,.contact.your.
gas.supplier.for.correction .
WARNING: Never use
an open flame to test for
gas leaks, as property
damage, personal injury, or
death could result.
WARNING: Failure to
install a water heater
suitable for the altitude at
the location it is intended to
serve, can result in improper
operation of the appliance
resulting in property
damage and/or producing
carbon monoxide gas, which
could result in personal
injury, or death.
