If you smell flue gas
Danger
Flue gas can lead to life-threat-
ening poisoning.
■ Shut down the heating system.
■ Ventilate the boiler room.
■ Close all doors in the living
space.

lead to damage to the heating
system and put the safe opera-
tion at risk.
■ Ensure ambient temperatures
above 0 ºC and below 35 ºC.
■ Prevent air contamination by
halogenated hydrocarbons
(e.g. as contained in paints,
solvents or cleaning fluids) and
excessive dust (e.g. through
grinding/polishing work).
■ Avoid continuously high humid-
ity levels (e.g. through frequent
drying of washing).

The commissioning and matching up of
the control unit to local conditions and
the structural characteristics of the build-
ing must be carried out by your heating
contractor.
As the user of new combustion equip-
ment, you may be obliged to notify your
local flue gas inspector of the installation
[check local regulations]. Local flue gas
inspectors will also inform you [where
appropriate] about work they may be
required to perform on your combustion
equipment (e.g. regular checks, clean-
ing).

bar.
If the system pressure is too low,
please notify your heating contrac-
tor.
2. During open flue operation (com-
bustion air is removed from the instal-
lation room):
Check that the ventilation openings of
the installation room are open and
unrestricted.
3. Open the gas shut-off valve.

Note
Frost protection for the entire heating
system - see operating instructions for
the room temperature control unit.
Shutting down the heating system
Shut down your heating system com-
pletely if it will not be needed for longer
periods of time (several months).
We recommend you contact your local
heating contractor if you are planning to
take your heating system out of use for
longer periods. Your heating contractor
can then take any necessary action, sub-
ject to requirements, e.g. frost protection
or preserving the heating surfaces.
1. Close the gas shut-off valve and safe-
guard against unauthorised reopen-
ing.
2. Switch ON/OFF switch OFF.
The power to the system is now
switched off.
Note that the system is no longer
frost-protected.

If a room temperature control unit is con-
nected, use this unit to set the desired
room temperature (see page 7).
If central heating is active, the display
shows "r".
Switching OFF:
Turn rotary selector "rt" to "0".
Domestic hot water
Select the DHW temperature in accord-
ance with your personal requirements
(e.g. for showering).
Switching ON:
Move rotary selector "tw" to the
required DHW temperature.
If DHW heating is active, the display
shows "w".
Switching OFF:
Turn rotary selector "tw" to "0".

der connected or an integral instantane-
ous water heater, turn the rotary selector

All appliances may be cleaned with a
commercially available domestic clean-
ing agent (non-scouring).
Inspection and maintenance
The inspection and maintenance of a
heating system is prescribed by the
Energy Savings Ordinance [EnEV - Ger-
many] and the DIN 4755, DIN 1988-8
and EN 806 standards.
Regular maintenance ensures trouble-
free, energy-efficient and environmen-
tally responsible heating. For this, we
strongly advise you to arrange an
inspection and maintenance contract
with your local heating contractor.
Boiler
Increasing boiler contamination raises
the flue gas temperature and thereby
increases energy losses. All boilers
should therefore be cleaned annually.
Logbook
Please ensure that you have a Logbook
supplied with your appliance. This Log-
book should be completed by your instal-
ler to verify that the correct installation
and commissioning procedure was fol-
lowed.
Failure to complete the Logbook may
result in difficulties should a problem
arise with your appliance during the
guarantee period. This Logbook forms
part of the industry's Benchmark code of
practice for the installation, commission-
ing and servicing of central heating sys-
tems.
All CORGI Registered Installers carry a
CORGI ID card and have a registration
number. Both should be recorded in your
Logbook. You can check your installer is
CORGI registered by calling CORGI on
0870 401 2230.
Drinking water filter (if installed)
For hygiene reasons
■ renew filter insert on non-backwashing
filters every 6 months (visual inspec-
tion every 2 months)
■ on backwashing filters, backwash
every 2 months.

You can also save energy by taking the
following steps:
■ Correct ventilation.
Briefly open window A fully and at the
same time close the thermostatic
valves B.
■ Never overheat rooms;
endeavour to achieve a room temper-
ature of 20 °C; you can save up to 6%
on your heating bills for every degree
you reduce your room temperature.
■ Close roller shutters (where installed)
at dusk.
■Adjust thermostatic valves B cor-
rectly.
■Never cover radiators C and thermo-
static valves B.
■ Utilise the setting options offered by
control unit D.
■ Only activate the DHW circulation
pump if DHW is being drawn.
■ Controlled DHW consumption: A
shower generally uses less energy
than a full bath.
