1.9.4 Standard 100 mm flue systems
The standard concentric flue system provides for a maxi-
mum horizontal straight length of upto 12.0 m for 60/100
flue connection (see subsection 1.9.3).
Full instructions for fitting this flue are in subsection 1.9.7:
"Installation of the horizontal flue" on page 24.
IMPORTANT
Any horizontal flue system fitted to a conden-
sing boiler must be inclined towards the ap-
pliance at an incline of 50 mm per metre
length to prevent condensate dripping from
the flue terminal. This means that the clear-
ance above the appliance must be increased
to match the duct length. See figure on
page 8.
NOTE
Take into account the extra depth of the boil-
er when using the wall-spacing frame.
