Note: The equivalent horizontal flue assembly length + the equivalent plume management length (PM length) must not
exceed the maximum flue length stated for each boiler, i.e.
E-Tec boilers - the maximum equivalent flue length must not exceed 12 metres.
Note:
1. Ensure each joint is
secured with the screw
supplied.
2. Ensure there is always
a slight slope towards
the CD Easy-Flue so
that there is no part
of the pipework where
condensate will collect.
