CAUTION
Personal injury due to lifting incorrectly.
▶ Due to the weight and dimensions of the boiler, take adequate
measures to transport the wall mounted boiler safely in the
installation room.
▶ The packaged boiler should ideally be transported to the installation
room on a sack truck or trolley.
NOTICE
The appliance may be damaged if lifted incorrectly.
Not all parts of the boiler are suitable for lifting and carrying. To lift the
boiler correctly, handles are attached to the underside.
▶ Use these handles to move the boiler [1].
▶ Hold the boiler at the side and base and not at the basic controller or
flue connection.

DANGER
Risk of fire through flammable materials or liquids.
▶ Never store flammable materials or liquids in the immediate vicinity
of the boiler.
NOTICE
Frost damage!
▶ Install the heating system in a frost-free room.
NOTICE
Boiler damage through contaminated combustion air or
contaminated air in the vicinity of the boiler!
▶ Never operate the boiler under dusty conditions or where the
atmosphere is contaminated with corrosive substances. These might
be, for example, paint shops, hairdressing salons and agricultural
operations involving the production of manure.
▶ Never operate boilers in locations where trichloroethene,
halogenated hydrocarbons or other corrosive chemical substances
are used or stored. Certain adhesives, solvents, cleaning agents and
paints, for example, contain these substances.
▶ Choose or prepare a suitable installation location.
NOTICE
The boiler may only be operated up to a maximum installation
altitude of 1200 m above sea level!
▶
Table 15 (technical data), see 46.
NOTICE
The boiler may be operated with combustion air up to a certain
maximum temperature!
The maximum temperature of the combustion air must not exceed 35 °C.
▶
Table 15 (technical data), see 46.

Important notices
The boiler must not be operated in open heating systems (open vented
systems that could lead to oxygen ingress). The heating system must
then be converted to a sealed system according to EN12828 or a system
separation must be installed:
▶ Mount a separation (a plate heat exchanger for example) between the
boiler and the heating system.
When plastic pipes are used in the heating system
If plastic pipes are used in the heating system, in an underfloor heating
system for example:
▶ Use plastic pipes with oxygen diffusion resistance to DIN 4726/
4729
-or-
▶ Mount a separation (a plate heat exchanger for example) between the
boiler and the heating system.
When using a room thermostat/room temperature-dependent
controller
▶ Do not mount thermostatic radiator valves in the reference room.
Surface temperature
The maximum surface temperature of the appliance is below 85 °C.
Therefore no special safety measures are required to protect flammable
materials and fitted furniture. Country-specific regulations must be
observed.
5.3
Water quality
Unsuitable or contaminated heating and tap water can lead to faults in
the boiler and can damage the heat exchanger or DHW supply among
other things due to sludge formation, corrosion or calcification. 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 of
this document.
