We advise to build a simple ue gas system and air supply system out of table 6.
For further information about the available components of the ue gas and air supply
system we recommend you consult the Monopass Flue systems.
The ATAG ue gas system is meant and designed solely the use on ATAG central
heating boilers adjusted for Nat gas or LPG. The maximum ue gas temperatures
are below 70°C (full load 80/60°C)
The proper operation can be inuenced harmfully 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: 0063BQ3021, 0063AS3538 and 0063AU3110.
The ue gas system should be built up using only ATAG program products.
Combinations with other brands or systems are without written permission from
ATAG Heating is 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 9).
