TheATAGiRboilerisacertiedapplianceandmustnotbemodiedorinstalledinanywaycontraryto
this Installation Manual. Manufacturers instructions must not be taken, in any way, as overriding statutory
obligations.
The ATAG iR boiler is a central heating boiler for "open" expansion tank systems (open vent) only. The boiler
must be connected according to these instructions and all installation norms in respect of the part of the
boiler to be connected.
Observe the following rules of safety:
- All work on the boiler must take place in a dry environment.
- ATAG boilers may never be in operation without their housing, except in connection with maintenance or
adjustments (see Chapter 15 and 16).
- Never allow electrical or electronic components to come into contact with water.
Carry out the following tasks in connection with maintenance, etc. to an already-installed boiler:
- Shut down all programs
- Close the gas isolation valve
- Shut down the 230V power supply
See chapter 15 and 16 for further instructions.
Take note of the following when maintenance or adjustments are needed:
- The boiler must be able to function during these activities; for this reason, the boiler’s 230V power supply,
gas pressure and water pressure must be maintained. Ensure that there is not a source of potential
danger during these activities.
Following maintenance or other activities; always check the installation of all parts through which
gas ows (using leak detection spray).

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
condensation.Thisresultsinaveryhighefciency.Thecondensatethatisformed,hasnonegativeimpact
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.
TheboilerhasbeentestedaccordingtovalidCEstandardsandhasaCEcerticateand>88%Efcient

Statement: No banned materials including asbestos, mercury, CFC's have or will not be included in
the product.
