SECTION C - STRUCTURAL SUPPORT AND GUIDING
ANCHOR PLATE ASSEMBLY (AP)
1.. .The.anchor.plate.support.assembly.is.designed.to.provide.maximal.
support.to.vertical.sections.and.to.provide.fixed.point.support.for.
horizontal.sections.
2.. .The.plate.support.must.be.attached.to.the.building.structure.or.sup-
ported.with.rigid.structural.members.(see.figure 22.and.table 12.for.
bracing.dimensions)
3.. DO NOT ATTACH THE ANCHOR PLATE TO COMBUSTIBLE CON-
STRUCTION...If.unavoidable,.use.the.Ventilated.Anchor.Plate.support.
assembly..
4.. .The.anchor.plate.consists.of.a.plate.and.eight.clamp.flange...See..
figure 21..for.sectional.details.for.plate.support.
5.. IMPORTANT: The surfaces of the male and female couplings
in contact with the plate of the anchor plate assembly must be
coated with inner joint sealant.
6.. .There.are.two.ways.of.assembling.parts.on.the.support...You.may.
choose.your.method.depending.on.your.situation.
6.1..The.first.method.consists.of.assembling.two.parts.and.the.anchor.
plate.on.the.side.and.then.installing.this.assembly.on.the.support.
structure...This.method.is.easier.and.faster.to.install,.but.requires.
enough.clearance.to.insert.the.complete.assembly.through.the.sup-
port.structure.opening...If.there.is.a.tee.or.elbow.upstream.of.the.
anchor.plate,.you.may.not.have.enough.clearance...Also.consider.
the.weight.of.the.assembled.parts.and.make.sure.you.have.a.safe.
manner.of.lifting.the.assembly.
INSTALLATION STEPS FOR FIRST METHOD (refer to figure 23)
1.. .Place.the.part.that.will.be.upsteam.of.the.support.on.the.floor.
2.. .Apply.a.bead.of.inner.joint.sealant.on.the.male.coupling.flange.
3.. .Slide.the.plate.of.the.anchor.plate.support.over.the.coupling.
4.. .Apply.a.second.bead.of.sealant.on.the.plate.around.the.male.
coupling.where.the.flange.of.the.female.coupling.of.the.next.part.
will.mate.
5.. .Place.the.second.part.over.the.plate...Make.sure.the.sealant.com-
pletely.fills.joints.between.the.plate.and.the.female.coupling.
6.. .Use.eight.clamp.flanges.and.bolts.to.tightly.clamp.the.parts.to.
the.support...
7.. .Insert.the.assembly.on.the.support.structure.and.fix.the.plate.to.
the.structure.using.the.supplied.hardware.
6.2..The.second.method.is.applicable.when.the.plate.of.the.anchor.plate.
support.needs.to.be.installed.first,.as.when.there.is.a.tee.or.elbow.
upstream.of.the.support...May.require.at.least.two.persons.to.complete.
the.installation.
INSTALLATION STEPS FOR SECOND METHOD (refer to figure 24)
1.. .Fix.the.plate.of.the.anchor.plate.support.to.the.structure.using.
the.supplied.hardware.
2.. .Apply.a.bead.of.inner.joint.sealant.on.the.male.coupling.flange.
of.the.part.before.the.support.
3.. .Insert.the.male.coupling.of.the.part.in.the.plate.opening.
4.. .You.may.hold.it.using.two.clamp.flanges.placed.at.180°.and.
bolted.to.the.anchor.plate...
5.. .Apply.a.bead.of.sealant.on.the.plate.around.the.male.coupling.
6.. .Place.the.second.part.over.the.plate...Make.sure.the.sealant.com-
pletely.fills.the.joint.between.the.plate.and.the.female.coupling.
7.. .Fix.the.assembly.by.clamping.it.with.four.clamp.flanges.on.the.
unused.flange.positions.
8.. .Remove.the.first.two.clamp.flanges.and.finish.clamping.the.as-
sembly.
VENTILATED ANCHOR PLATE (APV)
1.. .Use.for.same.application.as.the.anchor.plate,.but.can.be.attached.to.
combustible.construction.
2.. .Usually.uses.as.roof.support...See.section.D.for.details.on.how.to.
install.at.the.roof.level.
3.. .Installation.is.done.the.same.manner.as.the.anchor.plate.
4.. .See.Figure 25 .for.opening.dimensions.through.combustible.con-
struction.
5.. .Do.not.block.or.obstruct.openings.in.the.plate...They.are.intended.to.
minimize.heat.accumulation.

LENGTH ANCHOR PLATE (APL)
1.. .Use.for.same.application.as.the.anchor.plate.(AP).
2.. .It. is. composed. of. a. straight. section. -. with. an. effective. length. of............
3.3/4”.integrated.into.a.support.plate.(see.Figure 20.for.the.detail.of.
the.part).
3.. .Unlike.the.anchor.plate.(AP),.the.Length.Anchor.Plate.(APL).doesn’t.
need.any.clamp.flange.(and.its.hardware).for.its.installation,.so.it.is.
easier.and.faster.to.isntall.
4.. .The.APL.must.be.attached.to.the.building.structure.or.supported.by.
rigid.NON-COMBUSTIBLE.structural.members.(see.Figure.22.and.
Table.12.for.bracing.dimensions).
Installation.steps.for.the.APL
1.. .Fix.the.plate.of.the.APL.to.the.structure.using.the.supplied.hardware.
2.. .Follow.the.steps.of.the.«Chimney.and.fitting.assembly».section.in.
the.section A.on.page.5.to.connect.the.couplings.to.the.APL.with.
the.parts.downstream.and.upstream.
