Installation guideline
Preparatory measures
The fireplace should be hermetically connected to a well-functioning chimney, sufficiently
enclosed to keep combustible materials (floor and walls) at a distance, and should be installed
in a room with sufficient ventilation.
Please. inform. about. national. or. local. norms. and. regulations. concerning. this. subject..Your.
distributor.will.give.you.the.necessary.advice.
You can also consult the fire department and/or an insurance company about specific demands
or.regulations.
Please read the technical specifications under cover in this manual before installing the ap-
pliance.
The chimney
The chimney (the flue) has a double function:
• It.draws.air,.that.is.necessary.for.good.combustion,.into.the.stove.
• It.functions.as.an.exhaust.pipe.for.combustion.gases.via.thermal.or.natural.draught..Ther-
mal draught is caused by the difference in heat between the air in- and outside the flue.
The heated air in the flue is lighter than the colder air outside the flue and consequently
rises.up,.along.with.the.combustion.gases..Natural.draught.is.caused.by.environmental.
phenomena,.such.as.wind.
It.is. prohibited.to. connect.several.heaters.to. one. chimney.(for.instance.the. central.heating.
boiler),.unless.local.or.national.regulations.allow.this.
Please. check. which. chimney. is. to. be. used. for. the. stove. you. purchased. and. whether. your.
chimney is appropriate for this specific usage. You should consider an expert's opinion on
this.matter.
The.chimney.should.meet.the.following.conditions:
• The flue should be made of fireproof material. Ceramic or stainless steel is re-commen-
ded.
• The chimney should be airtight and thoroughly cleaned and should guarantee a sufficient
draught.(a.draught.or.negative.pressure.of.15.to.20.Pa.is.ideal.under.normal.circumstan-
ces).
• It.should.run.as.vertically.as.possible..Changes.in.direction.or.horizontal.segments.will.
disrupt the smoke flow and may cause soot to cumulate inside the flue (and clog the
flue!).
• The.chimney's.inside.dimensions.must.not.be.too.large.in.order.to.prevent.the.smoke.
from. cooling. off. too. much.. For. recommended. chimney. dimensions,. see. the. technical.
specification under cover. Larger dimensions can be used if the flue is well insulated.
