1.7.5 Standard 100 mm flue systems
The standard concentric flue system provides for a max.
horizontal straight length of upto 7.5 m for 60/100 flue
connection (see paragraph 1.7.3). Full instructions for
fitting this flue are in subsection 1.7.2: "Air supply and
flue gas exhaust in a closed installation" on page 22.
IMPORTANT
Any horizontal flue system fitted to a
condensing boiler must be inclined
towards the appliance at an angle of
30 mm per metre length to prevent
condensate dripping from the flue
terminal.
This means that the clearance above the
appliance must be increased to match the
duct length. See figure on page 15.
1.7.6 Connecting the vertical flue adaptor
Fit the vertical flue adaptor (fig. 16) onto the appli-
ance flue connector.
1.7.7 Connecting the horizontal flue turret
Fit the horizontal flue turret (fig. 17) onto the appli-
ance flue connector.
Subject to modifications resulting from technical improvements!
