Product description
The ATAG XL F is a condensing
andmodulatinggasboilerwithoneor
twopre-mixburners,oorstanding.Itis
characterizedbythefollowingfeatures:
- A large modulation range that
guaranteesalongburnerservice
life,whileminimizingstandby
losses, start-up emissions and
material wear-and-tear.
- Fluegastemperaturebelow80°C
- Alsosuitableforroomsealed
conditions
- Control panel with all operational
elements
- Microprocessor, with multi-
functional display
- Automated ignition, with repetition
and ionization monitoring
- Water pressure monitoring
- Energy-saving pump
- Stainless steel heat exchanger
withsmoothtubecondenser
- Very maintenance-friendly
- Ready for weather-dependent
control (accessory)
- Cascadecontrollerupto8boilers
- Externalcontrols(accessory)by
on/o󰀨,eBusor0-10V
- Modern metal panelling,
stove-enamelled
Functional description
Thecontrolunitmodiestheheating
performance to the current heating
requirements,bychangingthe
default values of the fan rotating
speed.Inthisregard,theboilerow
temperature is continually measured
via a sensor. In case of a deviation
of the actual temperature from the
target temperature, the control unit
reacts immediately and adjusts the
RPMofthefan,andwiththattheboiler
performance via the gas armature.
Adeviationcanbedueto:
- A changed default value of the
boilertemperature,viatheboiler
heating control unit
- A change on the outdoor
temperature
- Request for Domestic Hot Water
- Changed heating curve
By means of the integration of the
individual components in a system,
and within the control range of the
equipment,itisensuredthattheboiler
performance always corresponds to the
actual heating requirements.

Listedaccessorypartshavebeen
constructed or selected especially for
theATAGXLFboiler,which
means they are very easy to install
(plug and play). You can compose your
ownsystemsolution,byselectingthe
accessorycombinationthattsyour
needs. For details and prices, please
contact ATAG.
Incaseofcascadeconguration,
accessories that require an electrical
connectionshouldbeconnectedwith
Masterboiler(withtheexceptionof
tankprobeandClipin,thatcanbe
connectedalsotootherboiler).
Cascade
Inprincipleanycombinationis
possible.Theselectioncaninclude
modelswithdi󰀨erentoutputs,ifthis
meets the installation requirements.
Includingboilerswithcommonoutputs
assists with sharing load and run times
of individual appliance.
Thecapacityoftheowandreturn
header, gas line and low loss header
are adjusted to the selected overall
demand.
When installing a single ATAG XL F
boiler the use of a low loss header is
strongly recommended.
When installing cascaded ATAG
XL F boilers: the use of a low loss
header adjusted to the set demand
is mandatory; the realization of an
additional bypass is not allowed;
ow and return header should be
realized in a the dimension of DN65
or DN100 (according to cascade
output). ATAG supplies low loss
header versions, which are suitable
for a maximum demand of 1600kW.

The ATAG XL F is a fully equipped
compact heating system, which has
beenpre-setandtestedatthefactory.
Thepackagedimensionsforall
appliances are:
Width 750mm
Height 1200mm
Depth 800mm
Thismakesitpossibletotransport
all models in one piece through a
normal door.
Theboilercanbemovedusinga
fork-liftorpallettruck.Unpacking
instructions are printed on the
cardboardbox.Pleasefollowthe
proposed steps.
Disassembly of panelling
The appliance casing panels can
beeasilyremovedandthisis
recommended while the appliance is
beinginstalled.Thislimitsthepotential
for damage to occur.
Handling and carrying precautions:
- Wear protective clothing and gloves
to protect from any sharp edges.
- Theboilershouldbehandledwithits
palletusingaforklifter,wheelscan
beusedfornalpositioning.
Panelling should be attached and
secured with the supplied screw,

For single boiler installation the connection to a low velocity header and secondary circuit pump is strongly
recommended.
For installation of cascaded boilers the connection to a low velocity header and secondary circuit pump is
mandatory.
