nOTE: There must be no part of the air duct
(white tube) visible outside the property after

to allow condensate to run back to the boiler, for
disposal through the condensate discharge pipe.
When using extensions the fall along the flue
system must be increased to 3°.
Where extensions are used ensure the clearance
above the top of the flue elbow (X) is as shown in
