Toinstalltheconcentricsystemcommenceasfollows:
➠
Construct the system from the (connection stub of the) appliance up.
N.B.
- Maintain a distance of at least 50 mm between the outside of the concentric system and the walls and/or the ceiling;
If the system is built-into a cove for example, incombustible material should be applied all around;
- Use heat-resistant insulating material for ducts made of combustible material;
- The rosette (mounting inner plate) of the wall duct is too small to seal the Ø 250 mm opening when passing through
combustible material. That is why you should first apply a sufficiently large heat-resistant intermediate plate to the
wall. Then, the rosette is mounted on the intermediate plate.
➠
Connect the concentric pipe sections and the bend(s);
➠
Fit a clamping strip and silicone sealing ring to every connection;
➠
Secure the clamping strip with a self-tapping screw in places which will be inaccessible after installation;
➠
Use enough brackets to ensure that the weight of the pipes does not rest on the appliance;
➠
Determine the remaining length of the wall duct;
➠
Cut the wall duct to size;
!N.B.
- Make sure that the right insertion length is maintained;
- Place the wall duct with the groove/folded seam at the top;
- Make sure the horizontal concentric pipe pieces are sloping towards the wall duct, in order to prevent rain water
from entering.
➠
Mount the rosette (mounting inner plate); if necessary, on a heat resistant intermediate plate when passing through
combustible material;
➠
Attach the wall duct from the outside with four screws in their respective holes.
!N.B.
Some heat-resistant isolation materials contain volatile components that will spread an unpleasant smell for a pro-
longed time; these are not suitable.

➠
The construction of the chosen system has to be allowed. (See the procedure described below);
➠
First, a concentric pipe of at least 1 meter should be connected vertically to the appliance.
