Installing the water heater.
The water heater must be installed with the factory supplied blower assembly in place.
Venting
The.water.heater.must.be.vented.to.the.
outdoors.as.described.in.these.instructions ..
DO.NOT.connect.this.water.heater.to.
an.existing.vent.or.chimney.-.it.must.
be.vented.separately.from.all.other.
appliances .
NOTICE:.This.unit.can.be.vented.using.
only.the.following.recommended.pipe.
material ..Use.only.2-.or.3-inch.diameter.
pipe ..
PVC.(Schedule.40,.ASTM.D1785)
CPVC.(Schedule.40,.ASTM.F441)
ABS.(Schedule.40,.ASTM.D2661)
ABS..(Schedule.40.DWV,.Cellular.Core,.
ASTM.F628)
The.fittings,.other.than.the.TERMINATION,.
should.be.equivalent.to.the.following:
PVC.(Schedule.40.DWV,.ASTM.D2665)
CPVC.(Schedule.40,.ASTM.F438)
ABS.(Schedule.40.DWV,.ASTM.D2661)
The.unit.may.be.vented.horizontally.
through.a.wall.or.vertically.through.the.
roof .
Vent.pipe.runs.must.be.adequately.
supported.along.both.vertical.and.
horizontal.lengths ..
Maximum.unsupported.length.is.
recommended.to.be.no.more.than.6.feet .
It.is.imperative.that.the.first.hanger.
be.located.on.the.horizontal.length.
immediately.adjacent.to.the.first..
90-degree.elbow.from.the.vertical.rise.of.
vent.pipe.connected.to.the.water.heater .
The.support.method.used.should.isolate.
the.vent.pipe.from.floor.joists.or.other.
structural.members.to.help.prevent.the.
transmission.of.noise.and.vibration .
Do.not.support,.pin.or.otherwise.secure.
the.venting.system.in.a.way.that.restricts.
the.normal.thermal.expansion.and.
contraction.of.the.chosen.venting.material .
If.the.water.heater.is.being.installed.as.a.
replacement.for.an.existing.power.vented.
water.heater,.a.thorough.inspection.of.
the.existing.venting.system.must.be.
performed.prior.to.any.installation.work ..
..Verify.that.the.correct.materials.as.
detailed.above.have.been.used,.and.
that.the.minimum.or.maximum.vent.
length.and.terminal.locations.as.
detailed.in.this.manual.have.been.
met .
..Carefully.inspect.the.entire.venting.
system.for.any.signs.of.cracks.or.
fractures,.particularly.at.the.joints.
between.elbows.or.other.fittings.and.
the.straight.length.of.vent.pipe .
..Check.the.system.for.signs.of.sagging.
or.other.stresses.in.the.joints.as.a.
result.of.misalignment.of.any.
components.in.the.system .
..If.any.of.these.conditions.are.found,.
they.must.be.corrected.in.accordance.
with.the.venting.instructions.in.this.
manual.before.completing.the.
installation.and.putting.the.water.
heater.into.service .
NOTICE: The vent piping must be
connected to the blower assembly
using the rubber coupling and supplied
clamps. The vent pipe connections at
the blower assembly must be leak tested
with soap and water solution upon
initial startup. Repair any leaks before
allowing the water heater to operate.
DANGER: Failure to
install the blower assembly
and properly vent the water
heater to the outdoors as
outlined in the Venting
section of this manual will
result in unsafe operation of
the water heater causing
bodily injury, explosion,
fire or death.
To avoid the risk of fire,
explosion, or asphyxiation
from carbon monoxide,
NEVER operate the water
heater unless it is properly
vented and has adequate air
supply for proper operation
as outlined in the Venting
section of this manual.
The vent pipe must overlap
a minimum of ½” on each
connection. It is important
that the vent pipe engages
fully into any pipe fitting
and be kept in that position
until the adhesive has fully
cured. DO NOT drill or
punch holes in the plastic
pipe or fittings.
NOTICE: This unit is
equipped with a Flammable
Vapor Sensor. Do not
apply power until enough
time has passed to allow the
vapors from the primer and
cement to dissipate.
Blower Assembly Installation
Connect.blower.assembly.with.the.electrical.connector ..Attach.
Blower.Assembly.to.top.pan.using.the.six.(6).screws.provided.
(See.diagram.to.the.left) ..Install.rubber.coupling.(supplied.in.
the.box.with.water.heater).on.blower.housing.and.secure.it ...
Do not overtighten screws to ensure plastic does not crack.
NOTICE:
..The.Blower.Assembly.is.model.specific.and.only.
the.blower.assembly.supplied.should.be.used.on.this.water.
heater .
