Table II
Maximum permissible total duct-
ing length
20 m
40 m
80 m
A
1 bend, 90°
= 1 x 0.8 m relative pipe length
B/D
2 bends, 90°
= 2 x 0.8 m relative pipe length
C
0.5 m pipe
= 0.5 x 1 m relative pipe length
Total ducting length
Result: the total ducting length is less than 20 m (as per Table II). A
pipe diameter of 100 mm will therefore suffice.
You will need
- the connector (supplied).
- pipes and connecting pieces from a suitable retailer.
Only use heat-resistant materials with a temperature resistance of at
least 80 °C.
