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.
