3Operating manual ecoCRAFT
2 Safety instructions
3 Notes on the installation and operation
Filling pressure of the heating system
The filling pressure of the heating installation should be
checked at regular intervals.
Emergency power supply
Your specialist technician connected your gas heating
boiler to the electrical mains during installation.
If you wish to keep the unit running with an emergency
power supply in the event of a power failure, the
technical specification of the unit (frequency, voltage,
earthing) must be in agreement with the mains power
supply, and must be rated to at least the power
consumption of your unit. Please consult your heating
engineer on this subject.
Frost protection
If you are going to be away during a cold period, make
sure the heating system remains in operation and that
the rooms are sufficiently heated.
Caution!
The frost protection and monitoring devices are
only active if the mains switch of the unit is
depressed and shows a green light.
Addition of frost preventative medium to the
heating water is not permitted. Otherwise it
could result in damage to seals and diaphragms
as well as to noises in the heating operation.
Vaillant assumes no liability for this and such
consequential damages.
Your unit has a frost protection function: If the heating
flow temperature falls below 10°C with the main switch
turned on, the appliance starts up and heats the entire
heating circuit to approx. 20 °C.
3 Notes on the installation and
operation
3.1 Intended use
The Valliant ecoCRAFT units are state-of-the-art
appliances which have been constructed in accordance
with recognised safety regulations. Nevertheless, there
is still a risk of death or serious injury to the user or
others or of damage to the device and other property in
the event of improper use or use for which it is not
intended.
The units are intended as heat generators for hot water
- central heating installations. Any other use or extended
use is considered to be improper. The manufacturer or
supplier is not liable for any resulting damage. The user
alone bears the risk.
Intended use includes the observance of the operating
and installation manual and all other applicable
documents, as well as adherence to the maintenance
and inspection conditions.
Caution!
Any improper use is forbidden.
The appliances must be installed by a heating engineer,
who is responsible for adhering to the existing
regulations, rules and guidelines.
3.2 Requirements of the installation site
The Vaillant gas heating boilers ecoCRAFT must be
installed in boiler rooms. 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.
Caution!
Through-flow of the entire heating installation
cannot be guaranteed.
Another way to protect the heating system and the
appliance from frost is to drain them. You must ensure
that the system and the appliance are completely
drained.
Contact your heating engineer.
4 Operating manual ecoCRAFT
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
maximum allowed temperature of 85 °C.
When installing the unit, the recommended minimum
distances given in the maintenance manual should be
observed for reasons of accessibility.
3.3 Care
• Clean the exterior of your appliance with a damp cloth
and a little soap.
Note!
Do not use scouring or cleaning agents, which
may damage the housing or plastic fittings.
Notes on the installation and operation 3
3.4 Recycling and disposal
Both your Valliant ecoCRAFT gas heating boiler and its
packaging consist mainly of recyclable raw materials.
3.4.1 Appliance
Make sure the old appliance and any accessories are
disposed of properly.
3.4.2 Packaging
Please leave the disposal of the transport packaging to
the qualified servicing company which installed the
appliance.
Note!
Please observe the applicable national legal
regulations.
3.5 Energy saving tips
Installing a weather compensator
Weather compensators regulate the heating supply
temperature according to the outside temperature. No
more heat is created than is required. The designated
heating feed temperature for the corresponding outside
temperature must be set on the weather compensator.
This setting must not be greater than that required by
the design of the heating installation.
The correct setting is normally undertaken by the
heating engineer. Desired heating and set-back phases
(e.g. at night) are automatically turned on and off by
using integrated time programs.
Weather compensators combined with thermostat valves
are the most economical form of heating regulation.
Reducing the heating system
Reducing the room temperature at night and in your
absence. This is best and most reliably realised using
regulators with customisable time programs.
At such times, set the room temperature approx. 5 °C
lower than during full heating times. Reduction of more
than 5 °C brings no additional energy saving, because
then increased heating capacities would be needed for
the next full heating period. Only for longer absences,
e.g. holidays, is it worthwhile to further lower the
temperatures. However, in winter, make sure that there
is adequate frost protection.
Room temperature
Set the room temperature only as high as would be
enough for your comfort level. An extra degree would
mean increased energy consumption of about 6%.
Adjust the room temperature according to the purpose
of use of the room. For example, normally, it is not
required that bedrooms or seldom used rooms are
heated to 20 °C.
Setting the operating mode
In warmer seasons, when the apartment needs no
heating, turn the heating to summer mode. The heating
mode is then shut off, however, the device or the plant
remains ready for operation for water heating.
Uniform heating
Often, in an apartment with central heating, only one
room is heated. Through the encapsulation surfaces of
this room, i.e. walls, doors, windows, roofs, floors, the
unheated adjoining rooms are also heated in an
unregulated manner, i.e. unwanted heat energy is lost.
The capacity of the radiator in this one heated room is
obviously not enough for such an operating mode.
Consequently, the room can not be heated satisfactorily
and an uncomfortable feeling of coolness prevails (the
same effect is produced when doors between heated or
unheated or slightly heated rooms remain open).
This is incorrect saving: The heating is in operation and
still the room temperature is not comfortably warm.
Increased levels of heating comfort and more effective
operation are achieved if all rooms in an appartment are
heated evenly and in accordance with their utilisation.
The building structure can, by the way, also suffer if
sections of the building are unheated or only partially
heated.
Thermostat valves and room thermostat
It should be a matter of course, today, that all radiators
be fitted with thermostatic valves. They exactly maintain
the set room temperature. You can adjust the room
temperature to suit your individual requirements and
ensure effective operation of your heating installation
using the thermostatic valves in combination with a
room temperature regulator (weather compensator).
In the room where the room temperature regulator is
located, all the radiator valves should be fully opened
since otherwise the two regulating systems will work
against each other and the regulation quality can be
affected.
The following actions by the user are seen quite often:
As soon as the temperature in the room gets too hot the
thermostatic valves are turned down (or the room
thermostat is set to a reduced temperature). If it gets
too cold again after a time, the thermostatic valve is
opened up again.
This is not necessary since the temperature regulation
system takes over this task via the thermostatic valve: If
the room temperature rises above the value set on the
sensor head, the thermostat valve shuts off
automatically, when the temperature drops below the
defined value, it opens again.
5Operating manual ecoCRAFT
3 Notes on the installation and operation
4 Operation
Do not cover regulators
Do not cover your regulators with furniture, drapes or
similar objects. The room air must circulate unhindered.
Covered thermostat valves can be equipped with remote
sensors and thus still work.
Appropriate hot water temperature
The warm water should only be heated up to the extent
that is necessary for use. Any further heating results in
unnecessary power consumption and hot water
temperatures of more than 60 °C also lead to increased
lime scale production.
Energy-conscious use of water
Energy-conscious use of water can reduce your bills
considerably.
For example, taking a shower instead of a bath: Whereas
about 150 litres of water are required for a bath, a
modern shower equipped with water saving fittings only
requires a third of this water quantity.
By the way, a dripping water tap wastes up to 2000
litres of water and a leaking toilet flush up to 4000 litres
of water each year. On the other hand, a new seal only
costs a few cents.
Run circulation pumps only if needed
Hot water piped systems are often fitted with so-called
circulation pumps. These provide continuous recirculation of hot water in the piping system so that hot
water is immediately available, even at drawing-off
points which are located far away.
These circulation pumps can also be used with the
Vaillant ecoCRAFT. There is no doubt that they provide
increased comfort for hot water heating. Please bear in
mind, however, that these pumps consume electricity.
And circulating hot water that is not used cools off when
passing through pipes and then needs to be reheated.
Therefore, circulation pumps are to be operated only
when hot water is actually needed for the household.
Individual time programmes can be set using timers
which most circulation pumps have fitted to them or
with which they can be retro-fitted. Weather
compensators often have ancillary functions for
controlling circulation pump timings. Ask your heating
engineer about this.
4 Operation
4.1 Checks before start-up
4.1.1 Opening the shut-off valves
Note!
The shut-off valves are not included in the
scope of supply of your unit. They are fitted by
your heating engineer in the installation. He
should show you the location and how to
operate these components.
4.1.2 Checking water level
• Check the water level (fill pressure) of the installation
at the pressure gauge external to the boiler.
Your heating engineer has shown you the location of the
pressure gauge. It is not integrated into your unit. For
the heating system to operate properly, the indicator on
the pressure gauge should be at approx. 3 bar when the
system is cold. If it is less than 0.8 bar, then water
should be added.
There is a water pressure switch integrated in the unit
which prevents the unit from starting up if the system
pressure < 0.2 bar. This is shown in the display as E26.
At water pressures > 0.8 bar the fault display disappears.
If the heating system extends over several storeys, the
system may require a higher filling pressure. Ask your
engineer for details.
Ventilating residential spaces
During the heating period, open windows only for
ventilation and not for temperature regulation. A brief
impact-ventilation is more effective and energy-saving
than windows that are kept open for a long time. We
recommend that the windows be opened fully for a short
period. During ventilation, close all thermostat valves in
the room or set the room regulator to minimum
temperature. In this way, there will be adequate
ventilation without unnecessary cooling and energy loss
(e.g. by the heating switching on during the ventilation
procedure).

6 Care and maintenance
6 Care and maintenance
6.1 Care
Clean the exterior of your appliance with a damp cloth
and a little soap. Do not use scouring or cleaning agents,
which might damage the housing or plastic fittings.
6.2 Maintenance
Each machine needs care and maintenance after a
specified operating period to ensure that it will continue
to operate safely and reliably. Regular maintenance
forms the basis for continuous readiness for operation,
reliability and a long working life for your Vaillant
ecoCRAFT.
A well-maintained heating unit will operate at better
effectivity and will therefore be more economical.
Permanent operational readiness, safety, reliability and a
long service life require inspections and maintenance
work to be carried out regularly every year by a heating
engineer.
Danger!
Never attempt to perform maintenance or
repairs on your heating unit yourself. Assign an
approved qualified servicing company with this
work. We recommend signing a service
agreement*.
The reliability of the appliance can be impaired,
resulting in damage to property or personal
injury if maintenance work is not carried out.
6.3 Checking the system pressure
For the heating system to operate properly, the indicator
on the pressure gauge should be at approx. 3 bar when
the system is cold. If it is less than 0.8 bar, then water
should be added. Pay attention to the water quality and
the hardness of the filling water.
There is a water pressure switch integrated in the unit
which prevents the unit from starting up if the system
pressure < 0.2 bar. This is shown in the display as E26.
At water pressures > 0.8 bar the fault display disappears.
If the heating installation operates over several floors, it
may be necessary to have higher water levels on the
pressure gauge. Ask your heating engineer about this.
6.4 Filling unit/heating installation
Caution!
ecoCRAFT boilers consist of a heat exchanger
made of ALUMINIUM alloy. In order to inhibit
the natural corrosion process in a heating or
hot water system, the system must be
thoroughly flushed out before commissioning.
Deposits of lime and the formation of gas in the
water can lead to damage in the boiler, and the
system must be water-tight to avoid damage
The addition of chemicals such as e.g. frost and
corrosion prevention materials (inhibitors) is
not permitted.
Information concerning the filling and topping up of the
heating installation can be provided by your approved
heating engineer.
Proceed as follows to fill the installation:
• Open all thermostatic valves in the installation.
• Connect the filling and drain cock of the installation to
a cold-water tap using a hose. (Your heating engineer
should have shown you the filling fittings and should
have explained the filling and draining of the
installation to you).
• Turn the filling cock and the tap on slowly and add
water until the required installation pressure is shown
on the pressure gauge.
• Turn the tap off.
• Vent all the radiators.
• Re-check the pressure in the installation (if necessary
repeat the filling process).
• Close the filling cock and remove the filling hose.

When using a Vaillant exhaust gas duct adaptor for
Vaillant plastic exhaust systems (accessories), there is an
additional facility (1) for checking, at the back, on the
right hand side, just above the cladding cover.
If a Vaillant VRT heating regulator is connected in, the
"chimney sweep operation" should be set there in order
to carry out the measurements.
If the heating installation is not operated with a
regulator that has a "chimney sweep operation" mode,
you can set the boiler to maximum output by the use of
a combination of buttons.
