6 Boiler description
The ATAG iR is a room sealed, condensing and modulating CH boiler for "open" expansion tank systems
(open vent) only.
The boiler is equipped with a compact stainless steel heat exchanger with smooth pipes. It is a well thought-
out principle using sustainable materials.
The boiler burns gas to supply heat (natural gas and LPG versions available). This heat is transferred
intheheatexchangertothewaterintheCHinstallation.Therapidcoolingoffoftheuegasescauses

on the heat exchanger and it's operation, and is removed through the internal siphon. This feature requires a
condensate drain pipe connected to the drain of the building.
The boiler is equipped with an intelligent control system. The boiler anticipates on the heat demand of the
heating installation or hot water demand. This will cause the boiler to tune its capacity to the installation. This
means that the boiler will function longer and at a low level.
