4 Description
The ATAG XL is a condensing and modulating CH-boiler.
The boiler has one or two stainless steel heat exchangers with smooth pipes. A high-

The CH-boiler uses (natural) gas to supply heat. This heat is transferred in the heat
exchanger to the water contained in the CH-installation. Severe cooling down of the
ue-gasescauses condensation.That isthe reasonwhy they areso highlye󰀩cient.
Theinternalsiphondrainso󰀨theresultingcondensate,whichdoesnothaveanegative
impact on the heat exchanger or its functioning.
Theboilerisequipedwithitsowncontrollerperheatexchangerandisttedwithanin-
tegrated cascade manager. The control unit (MMI) allows central read-outs of settings.
Each boiler anticipates the heat demands of the CH-installation or the hot water supply.
Consequently, the boiler modulates its capacity to the installation. As a result, the boiler
will be operational longer at a lower level. The cascade manager controls the boiler order
and even allocation of burning hours.
Connected to an external sensor, the control can operate weather dependent. This means
thatthecontrolsystemmeasuresoutsidetemperaturesandwaterowtemperatures.
Usingthisdata,thecontrolsystemworksouttheoptimumwaterowtemperaturere-

ATAG XL CH-boilers are high-powered wall-mounted gas boilers for instances where
a lot of power is required. Cascading the XL CH-boilers provides ample room to con-
nect up to a maximum of 8 boilers and an output capacity of 1.1 MW. The XL-series is
structured as follows:
- XL70 Nominal capacity (80/60°C) 60.0kW
- XL110 Nominal capacity (80/60°C) 95.0kW
- XL140 Nominal capacity (80/60°C) 120.0kW
Explanation of type indication: ATAG XL 140
XL = Type
140 = Indication of input load in kW
In principle any combination is possible. Based on the requested capacity, ATAG’s online
cascadeconguratoro󰀨ersvariousoptions.
Youcanchooseeitherthemoste󰀩cientorthemostcompactsolutionyourself.
The capacity of the hydraulic pipes, gas line and low velocity header are adjusted to the
selected overall demand.
When installing a single XL boiler or cascaded XL boilers, you should always
use a low velocity header adjusted to the set demand. ATAG supplies 2 low ve-
locity header versions, which are suitable for a maximum demand of either 452
kW or 960kW (80/60°C) respectively.
If changes are made to the boiler construction the boiler no longer complies with
the CE requirements.
