TYPICAL HORIZONTAL VENT INSTALLATION

Vent (min.)
Figure 28
Support the vertical portion of the venting system
every 8 feet (2.4m) above the fireplace vent outlet.
Push. the. vent. component. against. the. collar.
until.it.fully.engages,.then.twist.the.component.
clockwise,.running.the.dimples.down.and.along.
the.incline.channels.until.they.seat.at.the.end.
of. the. channels.. . The. unitized. design. of. the.
Secure Vent.components.will.engage.and.seal.
both.the.inner.and.outer.pipe.elements.with.the.
same.procedure...Sealant.and.securing.screws.
are.not.required.
E. Attach vent components to each other -.Other.
vent.sections.may.be.added.to.the.previously.
installed.section.in.accordance.with.the.require-
ments.of.the.vent.tables...To.add.another.vent.
component.to.a.length.of.vent.run,.align.the.
dimpled.end.of.the.component.over.the.inclined.
channel.end.of.the.previously.installed.section,.
adjusting.the.radial.alignment.until.the.four.lock-
ing.dimples.are.aligned.with.the.inlets.of.the.four.
incline.channels.of.the.previous.section...Push.
the.vent.component.against.the.previous.section.
until.it.fully.engages,.then.twist.the.component.
clockwise.running.the.dimples.down.and.along.
the.incline.channels.until.they.seat.at.the.end.of.
the.channels..This seating position is indicated
by the alignment of the arrow and dimple as
shown in.Figure 19 on Page 14.
F..Install firestop/spacer at ceiling -
When.using.
Secure Vent,.use.SV8BF.firestop/
spacer.at.ceiling.joists..If.there.is.living.space.
above.the.ceiling.level,.the.firestop/.spacer.must.
be.installed.on.the.bottom.side.of.the.ceiling..
If.attic.space.is.above.the.ceiling,.the.firestop/.
spacer. must. be. installed. on. the. top. side. of.
the.joist...Route.the.vent.sections.through.the.
framed.opening.and.secure.the.firestop/spacer.
with.8d.nails.or.other.appropriate.fasteners.at.
each.corner.
Remember to maintain 1" (25 mm) clearance
to combustibles, framing members, and attic
or ceiling insulation when running vertical
chimney sections.
G..Support the vertical run sections -
See.
Section E.on Page 14.
H. Change vent direction - .At.transition.from.or.
to.a.horizontal/inclined.run,.install.the.SV8E45.
and.SV8E90.elbows.in.the.same.manner.as.the.
straight.vent.sections...The.elbows.feature.a.twist.
section.to.allow.them.to.be.routed.about.the.
center.axis.of.their.initial.collar.section.to.align.
with.the.required.direction.of.the.next.vent.run.
element..Twist elbow sections in a clockwise
direction only so as to avoid the possibility of
unlocking any of the previously connected vent
sections (see.Figure 19 on Page 14).
I..Continue installation of horizontal/inclined
sections -..Continue.with.the.installation.of.the.
straight.vent.sections.in.horizontal/inclined.run.
as.described.in.
Step E..Install.support.straps.
every.3.feet.(1914.mm).along.horizontal/inclined.
vent.runs.using.conventional.plumber’s.tape..
See.
Figure 28,.it is very important that the
horizontal/inclined run be maintained in a
straight (no dips) and recommended to be in
a slightly elevated plane, in a direction away
from the fireplace of 1/4" rise per foot (20 mm
per meter) which is ideal,.though.rise.per.foot.
run.ratios.that.are.smaller.are.acceptable.all.the.
way.down.to.at.or.near.level...
It is important to maintain the required clear-
ances to combustibles: 1" (25 mm) at all sides
for all vertical runs; and 3" (76 mm) at the top,
1" (25 mm) at sides, and 1" (25 mm) at the
bottom for all horizontal/inclined runs.
Use. a. carpenter’s. level. to. measure. from. a.
constant.surface.and.adjust.the.support.straps.
as.necessary..

A..Plan the vent run -.
Analyze.the.vent.routing.and.determine.the.
types. and. quantities. of. sections. required.......
4-1/2".(114.mm),.10-1/2".(267.mm),.22-1/2".
(572.mm),.34-1/2".(876.mm).and.46-1/2".(1181.
mm). net. section. lengths. are. available.. . It. is.
recommended.that.you.plan.the.vent.lengths.
so.that.a.joint.does.not.occur.at.the.intersection.
of.ceiling.or.roof.joists..Make.allowances.for.
elbows.as.indicated.in.Figure 21 on Page 15..
Maintain a minimum 1" (25 mm) clearance
to combustibles on the vertical sections.
Clearances for the horizontal runs are; 3"
(76 mm) on top, 1" (25 mm) on sides, and
1" (25 mm) at the bottom.
B..Frame exterior wall opening -.
Locate. the. center. of. the. vent. outlet. on.
the. exterior. wall. according. to. the. dimen-
sions. shown. in.
