2.9.2 Preparation

• Determine the installation site for the boiler with ref-
erence 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.
Note
h
The vertical air/flue duct and terminal accesso-
ry (Accy. No. 0020060570, 0020060571,
0020065937) 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 di-
rectly 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.
Note
If a 87° elbow is connected directly to the boil-
er, use the 48 mm
the vertical air flue duct at this position.
