Installation
Installation Connections
The installation location of the
CH-boiler(s) has to be, and remain,
frost-free.
It is NOT necessary to have a purpose
provided air vent providing a twin
pipe or concentric room sealed flue
system is used in the room or internal
space in which the boiler is installed.
Neither is normally required a provision
for general cooling due to the very
low heat loss from the boiler heat
exchanger and casing.
The floor should be flat and level and
have sufficient deadweight capacity
for the complete (filled) installation.
Wheels can be ad/-10mm to
compensate eventual floor irregularity.
The ATAG XL F cascade
can be mounted in 2 ways:
- Floor standing in line
All boilers standing alongside one

General guidelines:
Pay attention to the minimum
distance required between the
boilers, walls and ceiling for
installing and removing the housing
(refer to above) for commissioning
and servicing and installing the flue
system (refer to chapter 7).
If you have opted to build the hydraulic
part yourself, then ATAG recommends
using “Connection set ATAG XL F as
single boiler” for each boiler.
