Appendix C: Installation of the flue

Connection with use of concentric duct material
Make a hole of ø 153 mm for the wall or roof mounted terminal.
The horizontal pipes need to rise away from the appliance at a rate of 3 degrees
per metre
Build the system starting from the appliance on.
Make sure you place the pipes in the right direction, the narrow end towards the
appliance.
Make sure the pipes are fixed sufficiently, a wall clamp every 2m, so the weight of
the pipes is not resting onto the appliance.
The outside of the pipe can become hot (140 degrees). Stay 50 mm away from wall
surface or sealing. Make sure to provide sufficiently heat resistant isolation when
going through the wall or roof.
Because of expansion or cooling down the concentric pipes can turn loose. It is
recommended to fix the spring clip with a self tapping screw at inaccessible places.
To get the exact measure flue length you can use cut down concentric pipe, wall
mounted terminal or roof mounted terminal. To obtain a smoke sealed connection,
the inner pipe must be 20 mm longer then the outside pipe.
Connection onto an existing chimney
