We guarantee ease and fl exibility of installation for a gas-
fi red forced draught boiler thanks to the fi ttings and fi xtures
CZ
supplied (described below).
The boiler is especially designed for connection to an ex-
haust fl ue / air ducting, with either coaxial, vertical or hori-
zontal terminal. By means of a splitting kit a two-pipe sys-
tem may also be installed.
Exclusively install fi ttings supplied by the manufactur-
er.
CAUTION: To enhance operating safety, make sure
the fl ue ducts are fi rmly fi xed to the wall with suitable
brackets.
COAXIAL FLUE - AIR DUCT (CONCENTRIC)
This type of duct allows to disengage exhaust gases and to draw combustion air both outside the building and in case a
LAS fl ue is fi tted.
The 90° coaxial bend allows to connect the boiler to a fl ue-air duct in any direction as it can rotate by 360°. It can more ver
be used as a supplementary bend and be coupled with a coaxial duct or a 45° bend.

If the fl ue outlet is placed outside, the fl ue-air ducting must
protrude at least 18mm out of the wall to allow alluminium
weathering tile to be fi tted and sealed to avoid water leak-
ages.
Ensure a minimum upward slope of 1 cm towards the outside
per each metre of duct length.
• A 90° bend reduces the total duct length by 1 metre.
• A 45° bend reduces the total duct length by 0.5 metre.
• The fi rst 90° bend is not included in the maximum avail
able length.
