Placing of the concentric ue system
The concentric channel system consists of three parts: the channels itself, the transit through the roof or
through a wall and the out ow. The diameter for the ue pipes of the Square is 100/150 mm.
Instructions for placing the outlet
The out ow of the pipe system can be placed on top of the roof or against the side wall of the house.
Roof outlet
When placing the out ow on top of the roof, make sure that there is a distance of at least 50 cm between the
out ow and the edges of the roof, with the exception of a possible existing ridge. You must also take the place
of the out ow into account in relation to the existing ventilation openings, movable windows and combustion
air supply provisions. Please consult the national and local requirements.
Wall outlet
When placing the out ow into the side wall, make sure that there is distance of at least 50 cm between the
out ow and the corners of the building, eaves, gutters, balconies and etcetera. You need not have this distance
when the out ow runs through to at least the front of the overhanging part.
You must also take the place of the out ow into account in relation to the existing ventilation
!
openings, movable windows and combustion air supply provisions. Please consult the national and
local requirements.
Placing possibilities of the ue system
The total length of the pipe system must never be more than 10 metres excluding the passage through the
wall and the out ow. A 90° square angle counts as a length of 2 metres. A 45° turn counts as a length of 1
metre.
For the combined ue tube and combustion air supply you must apply one of the shown placing possibilities
of the WANDERS concentric pipe systems: with wall duct, with roof duct or with roof duct with bend.
