isolator, and check that it is no longer 'live'.
■Safeguard the system against reconnection.
Danger
Hot surfaces can cause burns.
■Before maintenance and service work, switch
OFF the appliance and let it cool down.
■Never touch hot surfaces on the boiler, burner,
flue system or pipework.
!Please note
Electronic assemblies can be damaged by elec-
trostatic discharge.
Prior to commencing work, touch earthed
objects such as heating or water pipes to dis-
charge static loads.

What to do if water escapes from the appliance
Danger
When water escapes from the appliance there is
a risk of electrocution.
Switch off the heating system at the external iso-
lator (e.g. fuse box, domestic power distribu-
tion).
Flue systems and combustion air
Ensure that flue systems are clear and cannot be
sealed, for instance due to accumulation of conden-
sate or other causes. Ensure an adequate supply of
combustion air.
Instruct system users that subsequent modifications to
the building characteristics are not permissible (e.g.
cable/pipework routing, cladding or partitions).
Danger
Leaking or blocked flue systems, or an inade-
quate supply of combustion air can cause life
threatening poisoning from carbon monoxide in
the flue gas.
Ensure the flue system is in good working order.
Vents for supplying combustion air must be non-
closable.
Extractors
Operating appliances that extract air to the outside
(cooker hoods, extractors, air conditioning units, etc.)
can create negative pressure. If the boiler is operated
at the same time, this can lead to reverse flow of the
flue gas.
Danger
The simultaneous operation of the boiler and
appliances that extract air to the outside can
result in life threatening poisoning due to
reverse flow of the flue gas.
Fit an interlock circuit or take suitable steps to
ensure an adequate supply of combustion air.

Danger
Wireless signals can interfere with electronic
devices, particularly cardiac pacemakers, hear-
ing aids and defibrillators.
If any such equipment is fitted, users should
avoid the immediate vicinity of the operational
wireless components.
The wireless components operate with a frequency of
868 MHz.
Where to install wireless components
■Install at mid wall height, at least 1 m below the ceil-
ing
■Distance to other transmitters (GSM, DECT, WLAN)
at least 2 m
■Distance from room corners at least 0.2 m
Use the Vitotrol 200 RF or Vitotrol 300 RF wireless
remote control, or the field strength meter made by

Range
Please note that in radio technology the range of wire-
less signals can be reduced by walls, ceilings and inte-
rior fixtures. These weaken the wireless signal, caus-
ing poor reception.
Preparing for installation
Observe prior to installation
5676 364 GB

Range reduction:
■On their way between transmitter and receiver, wire-
less signals are damped (e.g. by air or when pene-
trating walls).
■Wireless signals are reflected by metallic objects
(e.g. reinforcements embedded in walls, metal foil of
thermal insulation, thermal glazing with metallised
thermal vapour deposit).
■Wireless signals are isolated by service ducts.
■Wireless signals suffer interference from appliances
that also operate with high frequency signals
(such as computers, audio and video systems,
WLAN, electrical transformers, electrical ballast).
Distance from such appliances: At least 2 m.
Building materials that influence the range Remaining reception quality in %
Wood, gypsum, uncoated non-ferrous glass 90 to 100
Brick, hardboard or chipboard 65 to 95
Concrete with steel reinforcements, thermal glazing 10 to 90
Metal, aluminium backing 0 to 10
Note
If required, install a wireless repeater to increase the
range.
Angle of penetration
The reception quality remains best if radio signals hit
the walls vertically. Avoid wall recesses.
Depending on the angle of penetration, the effective
wall thickness changes and therefore the extent to
which the electromagnetic waves are damped.
A very flat angle of penetration can be avoided by
using a wireless repeater.
