Installation
For the realisation of concentric
air/flue gas systems the use of
original accessory parts by ELCO-
Klöckner is recommended.
Kits for connection of the air/ flue gas
pipes are supplied separately from the
appliance depending on the various
installation options.
The heating appliance is preset for
connection to a concentric air/flue gas
system.
Connection of the heating appliance
to the flue is effected for all appliance
with the aid of concentric hose pipes
ø 80/125 or via double hose systems
ø 80/80.
For each 90° change of alignment 1,5
m of the total hose length must be
deducted.
The additional resistance obtained
thereby must be taken into account in
the previously mentioned sizing.
