Connector for flue gas chimney B32
The flue gas chimney connection (17)
must be installed directly to the flue gas
chimney in accordance with the figure
shown (no extension piece between
flue gas chimney and flue outlet).
The air vents to the boiler room must be
free from obstruction.
The relevant local flue inspector must
check the suitability of the flue chimney
before installation.
Installation information:

Pitched roof: At 15 observe the
installation instructions
on the cowl, regarding
roof pitches.
Insert the roof outlet 8 from above
through the roof and secure vertically
with 16 to a rafter or brickwork.
Install the roof outlet only in its original

If an inspection aperture is required for the balanced flue,
insert a balanced flue with inspection aperture (4). When the
LAF length is greater than 2 m, when installing the boiler in
a cold area and/or the required heating output lies below
15 kW, we recommend the installation of a three-layered-
