Please note: Install the horizontal flue with approx. 3° fall (6 cm/m) towards
the boiler. During installation, slide the separator (8) fully
into the coupling. Push the next balanced flue (4) 50 mm
(dim. "S") into the coupling of the separator, and secure in
this location, e.g. with pipe clips DN 125 (5) or a fixing screw
on the air side.
Lubricate the pipe ends and gaskets for easier installation
(use only grease without silicone).
Determine the required inspection piece (3) (10) with your
NB
local flue gas inspector prior to installation.
