lengths for the bends). See Chapter 7Concentric pathways.
•90° bends have a 2-metre horizontal calculation length.
•45° bends have a 1-metre horizontal calculation length.
•The outlet can be installed at any point on the roof face or
exterior wall (supply and discharge in an identical pressure
area), but must meet applicable regulations.
•Flue pathways must not be insulated.

•The outlet may also be installed in an upwards exhaust
in the wall, taking any hindrance to the surrounding area
into consideration, in accordance with local standards
NOTE
Ensure wind pressure on the outlet is not excessive, such as
alleys, etc., as this can negatively affect the performance of
the appliance.
