VENTILATION THE RIGHT WAY
V E N T I L AT I O N & H E AT R E C O V E R Y
10.10
Cutting ventilation pipes on internal wall to length
►
Cut the ventilation pipes (item 1 in Fig. 19)
to length on the internal wall so that they
end flush with the internal plaster.
►
Deburr the ventilation pipes on the internal
wall.
NOTE
If you do not deburr the ventilation pipes there is a
risk of damaging the seals at the ventilation unit.
10.11
Sealing ventilation pipes on external wall
NOTE
If the external plaster encloses the ventilation
pipes all round and without gaps, you can skip the
steps described in this section.
►
Chamfer both pipe breakthrough edges
(item 1 in Fig. 20) to roughly 5x45° to
create enough space for the sealing joints
with permanently elastic sealant.
►
Fill the chamfers of the pipe breakthrough
edges all-round with permanently elastic
sealant on the outside.
NOTE
►
Only use a solvent-free sealant if the
sealant is applied to polystyrene.
