Introduction
Uponorventilationductingandcomponentsaremadeofpoly-propyleneplastic.Theyarelight-weightandeasytohandle.
Ductinstallationisnotrecommend-edattemperaturesbelow–15°C.Ductsmustnotbethrown,dragged,dented,orotherwisedamaged.

Remove duct plugs and protec- tive bags only at the time of installation. Open ends of in- stalled ducting must be protect- ed with duct plugs, which must be left in place until the valves are installed and adjusted.
Cleaningdoorsoftheductingmustbepositionedandinstalledinamannerthatallowscleaning.
Connectionsaremadebypushingtheductontopofthefittingasfarasthelimitingshoulder.Connectionsaremademanually;thecomponentsmaybelubricatedwithcleanwaterorwatermixedwithwashing-upliquid.Theconnectionsaremadewithoutscrewsorrivets.
Ducting
Cutting and connecting ducts
Uponorductsmustbecutperpen-dicularlybymeansofasawwithafinetoothpitching(1–2mm).Removethesawdustfromboththeoutsideandinsidesurfaces,andbeveltheinneredgeofthecutheadtofacilitateinsertionoftheconnectionpiece.
Ductconnections,changesindirec-tion,andbranchingmustbeim-plementedwithductcomponents.Thecomponentsareequippedwithsealingridgesmadeofthecompo-nentmaterial.Theductsdonothaveridges.
However, the vertical ducting sections must be supported so that their weight does not rest on the coupling. Ifbracketscannotbeused,theconnectionmaybesecuredwith8–10mmpoprivets,wherenecessary.

Theinsulationofductsisspecifiedintheventilationplans.Usually,thealternativesare:
Warm spaces (inside the vapour barrier):
•Supply and exhaust air ductsrequirenoinsulation,withtheexceptionofductsinsaunaceilings,whichmustbethermallyinsulatedwith50mmmineralwool.Ifthesupplyairistobecooled,thesupplyairductsmustbeinsulatedwithexpandedPEplastic.Iftheairflowinginthesupplyairductwillnotbepost-heatedinthewinter,theductsmustbeinsulatedwithexpandedPEplastic.
•Fresh and waste air ductsareinsulatedwithexpandablePEplasticinsulation,whichfunctionsasinsulationagainstcondensation.
Withextra-longfreshairducts,thepossibilityofheatlossshouldbeconsidered.Ifnecessary,freshairductscanbeinsulatedwith2x15mmexpandedPEplasticor,alterna-tively,15mmexpandedplastic+50mmmineralwoolinsulation.

Condensation-insulation of ducts and duct components is implemented with factory-installed 15 mm expanded PE plastic insulation.
