Fitting the flue system

For a correct installation of the flue pipe, re-
fer to the sheet provided together with the
pre-selected kit.
The horizontal routes of the flue pipes must
incline about 1.5 degrees (25 mm per me-
ter); therefore the terminal must be higher
than the intake at the boiler.
The single coaxial pipe with the terminal
must be fitted horizontal as the drainpipe is
already angled with the correct incline.
