Requirements of the installation site
Vaillant ecoCRAFT gas-fired condensing boilers must be
installed in a boiler room.
Ask your heating engineer which national regulations
must be observed.
The entire installation site should be frost-proof.
Observe the specified frost protection measures in
Chapter 2 if you are unable to ensure this requirement.
h
Note
It is not necessary to keep a clearance between
the appliance and combustible materials or
components, since at the rated heating power
of the appliance the temperature at the surface
of the housing is always lower than the maxi-
mum allowed temperature of 85 °C.
The minimum clearances for installation recommended
in the installation and maintenance manual should be
observed to ensure accessibility during maintenance
work.
3.4 Care
• Clean the casing of your unit with a damp cloth and a
little soap.
a
Caution!
Risk of damage
Do not use scouring or cleaning agents which
might damage the casing, fittings or controls.
Do not use sprays, solvents or cleaning agents
containing chlorine.
3.5 Recycling
and
disposal
Both your Valliant ecoCRAFT gas-fired condensing boil-
er and its packaging consist mainly of recyclable raw
materials.
3.5.1 Appliance
Do not dispose of your Valliant ecoCRAFT gas-fired con-
densing boiler or any of its accessories with household
waste. Make sure the old appliance and any accessories
are disposed of properly.
3.5.2 Packaging
Leave the disposal of the transport packaging to the
qualified servicing company which installed the appli-
ance.

Note
Observe the applicable national legal regula-
tions.
3.6 Energy
saving
tips
Installing a weather compensator
Weather compensators control the heating flow temper-
ature in response to the prevailing outside temperature.
No more heat is generated than is currently required. To
this end, the appropriate heating curve for the system
must be set on the weather-compensated controller. Al-
ternatively if there is a separate room thermostat
present, the room temperature can be set individually.
The correct setting is normally undertaken by the heat-
ing engineer. The required heating and set-back phases
(e.g. at night) are automatically switched on/off using
integrated timer programs. Owing to legal stipulations
concerning energy conservation, the use of weather-
compensated controllers and thermostatic valves
is specified.
Reducing the heating system
Reduce the room temperature during the hours of sleep
or periods of absence. This can be implemented most
simply and reliably by means of controllers with individ-
ually selectable timer programmes. At such times, set
the room temperature approx. 5 °C lower than during
full heating times. Reduction by more than 5 °C brings
no additional energy saving, because then increased
heating capacities would be needed for the next full
heating period. Reducing the temperature further is
only worthwhile for longer periods of absence, e.g. holi-
days, shut-downs. Take care in winter, however, that ad-
equate frost protection is maintained.
Room temperature
Only set the room/hall temperature high enough to en-
sure comfort. An extra degree would mean increased
energy consumption of about 6%. Adjust the room tem-
perature according to the specific use of the room. For
example, it is not normally necessary to heat rooms that
are seldom used to 20 °C.
Setting the operating mode
In warmer seasons, when the building/ apartments
needs no heating, we recommend switching the heating
to summer mode. The heating mode is then shut off,
however, the device or the plant remains ready for op-
eration for water heating.
Thermostat valves and room thermostat
Owing to legal stipulations concerning energy conserva-
tion, the use of thermostatic valves is specified.
Once set, they maintain the room temperature exactly.
Using thermostatic valves, the room temperature can be
customised to your requirements and economical opera-
tion of your heating system can be achieved.
And besides, the following user behaviour can frequent-
ly be observed: as soon as the room appears to get too
warm, the user goes and turns down the thermostatic
valve. If he feels too cold again after a while, he turns
the thermostatic valve up again. Such behaviour is not
