Care and cleaning of the water heater.
Draining the Water Heater
!
CAUTION: Shut off gas to the water
heater at the
gas control
(thermostat) gas
cock or manual shut-off valve before
draining water.
!
DANGER: Before manually operating the
temperature and pressure relief valve, make
certain no one will be exposed to the hot
water released by the valve. The water
drained from the tank may be hot enough to
present a scald hazard and should be
directed to a suitable drain to prevent injury
or damage.
Before.turning.off.the.cold.water.supply.to.
the.water.heater,.open.a.hot.water.faucet.
allowing.sufficient.cold.water.into.the.
tank.to.prevent.the.risk.of.a.scald.injury.
while.draining.the.water.heater ...Once.the.
water.in.the.tank.is.no.longer.hot,.turn.off.
the.cold.water.supply.to.the.water.heater ...
Open.a.hot.water.faucet.or.lift.the.handle.
on.the.relief.valve.to.admit.air.to.the.tank ..
Attach.a.garden.hose.to.the.drain..

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 .
Inspect.plastic.vent.pipe ...Make.certain.
that.all.joints.are.secure.and.that.vent.
pipe.supports.are.all.in.place ...Check.
the.outdoor.vent.terminal.to.see.that.it.is.
free.of.obstructions,.and.that.there.is.no.
damage.nearby.casused.by.condensate .
Inspect.dilution.air.inlet.and.combustion.
air.inlet.openings ...Make.certain.no.
blockage.exists ...Clean.any.lint,.dirt.or.oil.
accumulation.that.may.exist .
At.least.once.a.year,.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.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.
water.deposits.to.accumulate.in.the.bottom.
of.the.tank ...If.allowed.to.accumulate,.
these.solids.can.cover.the.gas.control.
(thermostat).sensors,.causing.the.sensors.to.
operate.erratically ...Because.accumulated.
solids.can.prevent.the.gas.control.
(thermostat).sensors.from.accurately.
reading.the.water.temperature,.the.water..
at.the.fixture.can.be.hotter.than.the.gas.
control.(thermostat).setting ...It.is.suggested.
that.a.few.quarts.of.water.be.drained.from.
the.water.heater’s.tank.every.month.to.
clean.the.tank.of.these.deposits ..
Rapid.closing.of.faucets.or.solenoid.valves.
in.automatic.water.using.appliances.can.
cause.a.banging.noise.heard.in.a.water.
pipe ..Strategically.located.risers.in.the.
water.pipe.system.or.water.hammer.
arresting.devices.can.be.used.to.minimize.
the.problem .
The.anode.rod.should.be.removed.from.the.
water.heater’s.tank.annually.for.inspection.
and.replaced.when.more.than.6”.of.core.
wire.is.exposed.at.either.end.of.the.rod .
Make.sure.the.cold.water.supply.is.turned.
off.before.removing.anode.rod .
This.water.heater.incorporates.a.
combustion.shut.off.device.that.shuts.
the.operation.of.the.water.heater.down.if.
undesirable.combustion.conditions.occur,.
such.as.the.presence.of.flammable.vapors.
or.blockage.of.the.combustion.air.inlet.
openings ...Please.contact.a.qualified.
Service.Technician.if.this.occurs .
DANGER: Failure to perform the
recommended Routine Preventative
Maintenance can harm the proper
operation of this water heater, which
can cause carbon monoxide dangers,
excessive hot water temperatures and
other potentially hazardous conditions.
DANGER: Before
manually operating the
relief valve, make certain
no one will be exposed to
the danger of the hot water
released by the valve. The
water may be hot enough to
create a scald hazard. The
water should be released
into a suitable drain to
prevent injury or property
damage.
!
DANGER: Hotter water
increases the potential for
Hot Water Scalds.
