Example 2
Common combined exhaust ducting for multiple appliances should only be considered as
a solution in exceptional cases.
Configuring combined exhaust ducting made from steel for the PDR 914/514 and PDR
918/518 series tumble dryers:
L1–L4
each 6' 6" (2 m) steel piping
B1–B3
each 90° concertina pipe elbow (r = 2d)
B4
45° elbow (r = 2d)
B5
90° elbow (r = d)
If the exhaust from multiple appliances is to be ducted into a combined line, a non-return
device must be installed in each separate line to prevent backflow.
