)

ecommendations
Horizontal balanced flue installation is
possible when the wall next to the boiler
leads to a well-ventilated area on the
outside.
Do not place the flue terminal at the
front of the building or in an access
area (possible obstruction).
The horizontal balanced flue can be fit-
ted to the right or lefthand side or di-
rectly to the rear of the boiler and can
cross a wall-thickness of 1 metre maxi-
mum.
Two balanced flue terminals from two
separate boilers, positioned side by si-
de, must be separated by a minimum
distance of 0.
3
metres.
When installing the horizontal balanced
flue, use a 2% upward grade towards
the outside for the combustion product
tube.
To make assembly easier, apply liquid
soap over 5 cm of the section of the
tube to be fitted.
