• The flue's diameter should be the same throughout its whole length. Wider, or especially
narrower segments will disrupt the smoke flow and are best avoided. The same is true
for.a.cover.plate.or.exhaust.hood.on.top.of.the.chimney..The.exhaust.hood.must.not.nar-
row.the.chimney's.outlet.and.should.be.designed.in.a.way.that.wind.will.not.hinder,.but.
promote the smoke flow.
• Especially if the flue runs through unheated rooms or outside the house, further insula-
tion.is.necessary..Metal.chimneys,.or.parts.of.the.chimney.outside.heated.rooms.should.
always have double-walled, insulated flues. The part of the chimney outside the roof
should.always.be.insulated.
• The.chimney.should.be.high.enough.(at.least.four.metres).and.should.end.in.a.zone.that.is.
clear.of.nearby.buildings,.trees.or.other.obstacles..The.rule.of.thumb.here.is:.60.cm.above.
the.ridge.of.the.roof..If.the.distance.between.the.ridge.and.the.chimney.measures.more.
than.three.metres,.see.the.dimensions.stipulated.in.the.illustration.below..Depending.on.
the.presence.of.nearby.buildings.or.trees,.the.chimney.should.be.higher..
highest.point.of.the.roof
with.a.distance.of.3.m.
Ventilation
The.burning.of.wood,.charcoal.or.gas.involves.oxygen.consumption..It.is.of.the.utmost.impor-
tance that the room in which the stove is installed should be sufficiently ventilated.
Insufficient ventilation may disrupt the combustion process and cause the smoke flow through
the.chimney.to.be.interrupted,.which.may.lead.to.smoke.emissions.into.the.room.
If necessary, you can install a ventilation grille to provide a constant flow of fresh air in the
room..This.precaution.is.particularly.necessary.in.well-insulated.rooms.with.mechanical.ven-
tilation.
Ensure.not.to.use.other.air-consuming.appliances,.such.as.heaters,.cooking.hoods,.bathroom.
ventilators,.in.the.same.room.or.in.the.house.while.the.stove.is.burning;.or.make.sure.to.have.
an.extra.ventilation.grille.installed.for.these.appliances.
If.your.appliance.is.provided.with.a.connection.kit.(available.as.an.option).for.supplying.the.
combustion.air.from.outside.the.room,.you.do.not.need.to.provide.your.appliance.with.any.
extra.air.intake.
Ensure that there is sufficient ventilation in the area from which you draw the air.
