Installation of the flue
6.1
Connection with use of concentric duct material
1)
Build the system starting from the appliance on.
2)
Make a hole of ø 153 mm for the wall or roof mounted terminal.
3)
Make sure you place the pipes in the right direction, the narrow end
towards the appliance.
4)
Make sure the pipes are fixed sufficiently, a wall clamp every 2m, so
the weight of the pipes is not resting onto the appliance.
5)
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.
6)
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.
7)
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.
8)
The horizontal pipes need to rise away from the appliance at a rate of
3 degrees per metre.
6.2
Connection onto an existing chimney
You can connect the appliance onto an existing chimney. The existing
chimney then functions as air supply, where a flexible stainless steel liner
(to BS715) of 100 mm performs the flue function. Any existing chimney
used as an air supply must only service this appliance.
Requirements:
•
300 mm of free space above the appliance;
•
The chimney only supply’s air to this appliance;
