Placing The Concentric Channel System; Instructions For Placing The Outflow; Placing Possibilities For The Pipe System - WANDERS COCOS Mode D'emploi Et Instructions D'installation

Placing the concentric channel system

The appliance is approved according to the European CE regulations for gas appliances with the WANDERS
concentric flue systems (Ø 100 / 150 mm) and are to used only in that combination. The warranty will be partly
or entirely invalid if another system is used during installation. The WANDERS concentric system (Ø 100 / 150
mm) can be used with existing situations or newly built situations.

Instructions for placing the outflow

The outflow of the pipe system can be placed on top of the roof or against the side
wall of the house.
Outflow on top of the roof
When placing the outflow on top of the roof, make sure that there is a distance of at
least 50 cm between the outflow and the edges of the roof, with the exception of a
possible existing ridge. You must also take the place of the outflow into account in
relation to the existing ventilation openings, movable windows and combustion air
supply provisions. Please consult the national and local requirements.
Outflow into the wall
When placing the outflow into the side wall, make sure that there is distance of at least
50 cm between the outflow and the corners of the building, eaves, gutters, balconies
and etceteras. You need not have this distance when the outflow runs to at least the
front side of the overhanging part.
You must also take into consideration the place of the outflow in relation
!
to the existing ventilation openings, movable windows and combustion air
supply provisions. Please consult the national and local requirements.

Placing possibilities for the pipe system

The total length of the pipe system must never be more than 10 metres excluding the passage through the
wall and the outflow. The maximum horizontal length is 3 metres. A 90° square angle counts as a length of 2
metres. A 45° turn counts as a length of 1 metre.
For the combined flue tube and combustion air supply you must apply one of the following set-up possibilities
of the WANDERS concentric pipe systems: with wall duct, with roof duct, or with roof duct with bend.
Because of the high outer temperatures of the flue system ( around ± 150°C) it's not allowed to use flammable
materials near the flue system. Therefore it is advised to surround the flue system, on locations where it is not
in direct view, with non-flammable materials. Make sure this construction is sufficiently ventilated (per floor)
by installing ventilation grids near the floor and the ceiling.
!
It's not allowed to insulate the concentric flue system.
Use universal wall brackets of Ø 150 mm to attach the surround of the concentric flue system to any construction.
Select one of the connection possibilities. Then build up the first metre of concentric pipe from the counterpart
in the appliance. If you can see the blue rubber ring in the pipe from above, you will know that the assembly is
correct. Keep a distance of at least 5 centimetres between the outer wall of the concentric pipe and the ceiling.
Always start with 1 meter vertical.
Pay special attention to proper installing when, due to circumstances, a part of the double-walled pipe system
must be built in.
