The equivalent horizontal flue assem ly the equivalent plume management length (PM length) must not
exceed the maximum flue length stated or each boiler, i.e.
Alpha InTec boiler maximum equivalent flue length ust 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
