Vertical air/flue duct
Accy. No.: 303 900 (black)
Contents of the accessory:
• Vertical air/flue duct and terminal
assembly

• Fixing bracket
☞ See page 6 et seq. for details of
air/flue duct elements.
☞ Observe the maximum flue

page 11.
Fig. 5.1: Vertical roof duct
The air/flue duct assembly may be
connected directly to the flue outlet
on top of the boiler.
In addition to the vertical air/flue
duct and terminal accessory, air/flue
duct extensions can be added to
increase the length of the flue.
Preparation
• Determine the installation site for
the boiler with reference to the
installation and servicing
instructions supplied with the
boiler.
• Ensure that all installation and
service clearances are available
and that the boiler flue can be
installed as detailed in these
instructions.
• Determine the point where the
vertical air/flue duct and terminal
assembly will penetrate the roof.
☞ Please note: The vertical air/flue
duct and terminal accessory
(Accy. No. 303 900) may be
shortened. The outer ‘white’ duct
should be shortened first, then the
inner flue duct cut so that it
protrudes 13 mm out of the air
duct. In case of installation
directly to the boiler without
elbows or bends, it is essential
that the roof tile/collar is vertically
aligned with the air/flue duct of
the boiler.
☞ Please note: If a 87° elbow is
connected directly to the boiler,
use the 40 mm air duct clamp
supplied with the vertical air flue
duct at this position (fig. 5.2).
