In addition, it is also possible to use a split (twin pipe)

system b

y fitting a special adaptor to the flue connector

and using the aperture for the air vent intake located on

the top par

To utilise the air intake it is necessary to:

1. Remove the bottom of the air intake by cutting it with a

suitable knife (see FIG. 2.7);

Insert the elbow into the air intake until it reaches the

wer end. (There is no need to use gaskets or sealing

compounds).

IMPORTANT!

For all flue systems, a restrictor

must always be inserted into the

boiler’s flue connector; the

restrictor must be Ø 46 or Ø 41 in

diameter depending on the length

of piping indicated in T

ABLE 2.1.
