Fitting the flue system
For a correct installation of the flue pipe, refer
to the sheet provided together with the pre-
selected kit.
The horizontal run
of the flue pipes must in
-
cline about 1.5 degrees (25 mm per meter);
therefore the terminal must be higher than the
intake at the boiler.
The standard horizontal flue kit must be fitted
horizontal as the
inner flue exhaust pipe
is al-
ready angled with the correct incline.
