5 Assembly
WARNING:
Gas explosion.
Turn off gas valve before working on gas-carrying components.
Check for leaks before working on gas-carrying components.
5.1 Important information
If the wall mounted gas condensing boiler is used in heating systems with
natural water circulation or open systems (where heating water is in
contact with outdoor air):
Mount a system separation (a plate heat exchanger for example)
between the wall mounted gas condensing boiler and the heating
system
If plastic pipes are used in the heating system, with an underfloor heating
system for example,
use plastic pipes with oxygen diffusion resistance to DIN 4726/4729
-or-
Mount a system separation (a plate heat exchanger for example)
between the wall mounted gas condensing boiler and the heating
system.
5.2 Water quality
Unsuitable or contaminated heating and tap water can lead to faults in
the wall mounted gas condensing boiler and can damage the heat
exchanger or DHW supply among other things due to sludge formation,
corrosion or limescale deposits. Please get in touch with the
manufacturer if you require additional information on the water quality.
You will find the relevant addresses on the back cover of these
instructions.
Determine the water volume V
max
by referring to the “Water quality
operator's log”:
If the amount of fill and top-up water is already greater than the
calculated water volume V
max
:
Use the water treatment in accordance with “Water quality operator's
log”.
If the amount of fill and top-up water is less than the calculated water
volume V
max
:
Flush and clean the heating system if necessary.
Only use untreated mains water.
Do not use any chemical additives (e.g. inhibitors or pH-increasing or
reducing agents) other than those approved by Bosch
Thermotechnik.

5.3 Unpacking the wall mounted gas condensing boiler
To ensure the connections are not damaged, only remove the
styrofoam at the bottom once the wall mounted gas condensing
boiler has been hung.
Remove packaging and dispose of it.
Prevent damage to the connections.
Cover the connection for the flue gas/air supply on the top of the wall
mounted gas condensing boiler.
5.4 Check gas type
Make sure that the gas type to which the wall mounted gas
condensing boiler is connected corresponds to the gas type specified
on the data plate ( figure 4, [8]).
5.5 Mounting the wall mounted gas condensing boiler
NOTICE:
Damage to appliance due to incorrect lifting.
Lift the wall mounted gas condensing boiler with one hand
underneath and the other on top of it.
The wall mounted gas condensing boiler may only be hung on the wall or
installed on a cascade frame.
Wall-mounted installation
Check whether the wall is strong enough to support the weight of the
wall mounted gas condensing boiler.
Mount a fastening structure if required.
Determine the position of the wall mounted gas condensing boiler on
the wall.
Mark holes using the supplied mounting rail ( figure 10).
Install the mounting rail on the wall with the assistance of a spirit
level.
