Placing of the concentric fl ue system
The concentric channel system consists of three parts: the channels itself, the transit through the roof or
through a wall and the outfl ow. The diameter for the fl ue pipes of the Square is 100/150 mm.
Instructions for placing the outlet
The outfl 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 outfl ow on top of the roof, make sure that there is a distance of at least 50 cm between the
outfl ow and the edges of the roof, with the exception of a possible existing ridge. You must also take the place
of the outfl 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 outfl ow into the side wall, make sure that there is distance of at least 50 cm between the
outfl ow and the corners of the building, eaves, gutters, balconies and etcetera. You need not have this distance

!
openings, movable windows and combustion air supply provisions. Please consult the national and
local requirements.
Placing possibilities of the fl ue system
