STARTING ADAPTORS
Single Wall Adaptor (SWA)
1.. The.Single.Wall.Adaptor.is.used.as.an.appliance.connector...It.is.de-
signed.to.be.clamped.with.a.Retaining.Band.and.a.locking.band.over.
a.shank.type.flue.gas.outlet.
2.. First,.slide.the.retaining.band.over.the.appliance.outlet.and.tighten.it.
with.supplied.bolt..(See.figure 38).
3.. Add.a.bead.of.sealant.about.1/8”.on.the.flange.of.the.retaining.band.
and.one.on.the.flange.of.the.adaptor.(SWA).and.mate.those.two.flanges.
together...Be.sure.to.fill.all.the.gaps.with.S-2000.sealant..(See.figure
39 and figure 40).
4.. Tighten.the.Locking.Band.to.hold.and.seal.the.adaptor.in.place...See.
Figure 41.for.typical.installation.
ANSI Flange Adaptor (FA)
1.. .The.Flange.Adaptor.(FA).is.intended.for.use.as.a.connection.to.a.class.
125.or.150.ANSI.pipe.flange.
2.. This.type.of.connection.requires.a.flange.gasket.and.bolt.set.provided.
by.the.installer...The.gasket.and.bolts.are.typically.sold.by.pipe,.valve.
and.fittings.houses.as.‘NBG’.set.. Figure 42..illustrates.a.typical.instal-
lation.
3.. An.outer.band.with.insulation.is.included.to.close.the.installation.
Flanged Adaptor (FHA)
1.. The.Flanged.Adaptor.(FHA).is.used.to.connect.the.DIS./.DAS.chimney.
to.flanged.appliance.outlets.other.than.those.with.ANSI.pipe.flanges.
2.. The.adaptor.is.designed.to.sandwich.an.1/2.inch.flange.between.two.
half.ring.and.the.appliance.flanged.outlet...The.Flange.Adaptor.comes.
with.beam.clamps.to.clamp.the.FHA.to.the.appliance..See.Figure 43.
DIS/DCT, DCT/DIS, DAS/DCT, DCT/DAS Adaptor
1.. Used.to.connect.model.DIS./.DAS.chimney.to.model.DCT.chimney...

Female Single Wall Adaptor (FSWA)
1.. The.Female.Single.Wall.Adaptor.is.used.as.a.connector.to.specialised.
component. or. existing. chimney. connection.. . It. is. designed. to. be.
clamped.with.a.Retaining.Band.and.a.locking.band.over.a.shank.type.
flue.gas.inlet.
2.. First,.slide.the.retaining.band.over.the.system.inlet.and.tighten.it.with.
supplied.bolt..(See.figure 38a).
3.. Add.a.bead.of.sealant.about.1/8”.on.the.flange.of.the.retaining.band.
and.one.on.the.flange.of.the.adaptor.(SWA).and.mate.those.two.flanges.
