We suggest you design a simple ue gas system and air supply system using table 6.
For further information about the available components of the ue gas and air supply
system we recommend you consult the Duopass Flue system literature.
The ATAG ue gas system is meant, and designed, solely for the use on ATAG central
heating boilers adjusted to Nat gas or LPG. The maximum ue gas temperatures are
below 70°C (full load 80/60°C)
The proper operation may be adversely inuenced by changes of or adjustments to the
correct set up.
Possible warranty claims will not be honoured if incorrect changes result in non compliance
with the installation manual or local rules and regulations.
The ue gas systems described in this document are solely suited for ATAG central
heating boilers of the ATAG boiler range. For this purpose the CE Certicate has been
supplemented under the Gastec nr: 0063BR3405, 0063BQ3021, 0063AS3538 and
0063AU3110. 0063BQ3021, 0063BT3195 en 0063CM3648
The ue gas system should be built up using only ATAG program products. Combinations
with other brands or systems, without written permission from ATAG Heating, are not
permitted.
Horizontal ue system should always be installed sloping towards the boiler, in order to
avoid condensate lying in the ue system.
The minimum gradient is 50mm/Mtr. With the condensate running back to the boiler the
risk of ice forming at the terminal is reduced.
The terminal should be located where dispersal of combustion products is not impeded
and with due regard for the damage or discolouration that might occur to building products
in the vicinity (see g 6.8.b).
