2.1 Erection and adjustment
Installation and adjustment of the boiler and service,
maintenance and repair work may only be carried out
by expert technicians in accordance with regulations introduced in 1998 governing the safety of gas installations (installation and use). (In Great Britain "CORGI".
This means that the work carried out by registered installation companies must always be to a safe and satisfactory standard.) If the boiler is mounted in a cabinettype enclosure the ventilation openings must not be obstructed and the enclosure must not be used for storage purposes.
2.2 Action in case of emergency

2.3 Safety instructions
Always observe the following safety instructions and
regulations.
Procedure in case of gas smell in buildings
• Open doors and windows wide, facilitate through
movement of air, stay out of rooms where gas odour
is present!
• Avoid naked flames, do not smoke, do not use pocket
lighters!
• Do not use electric switches, plugs, bells, telephones
and other communication systems in the building!
• Close gas meter isolator device or main isolator de-
vice!
• Close gas isolator cock (1, Fig. 2.1) on unit!
• Warn other building residents, but avoid ringing door-
bells!
• Vacate building!
• Inform the gas supply company stand-by service from
a telephone outside the building!
• If a gas leak is audible, leave the building immediately,
prevent others from entering the building and notify
the police and fire brigade from outside the building!
Danger!
d
Inflammable mixtures of gas and air may explode!
Do not use or store explosives or highly flammable substances, such as petrol or paint, in
the same room as the unit.
Danger!
d
Risk of poisoning and explosion due to a malfunction!
Never put the safety devices out of operation
or tamper with them so as to impair their
function.
Therefore, do not attempt any modifications:
- to the unit,
- around the unit,
- to the gas, air, water and electricity supply pipes,
- to the expansion relief valve and drain line for the
heating water,
- to the flue gas pipes.
This also applies to alterations to structural elements in
the vicinity of the appliance which might affect its operational safety.
Example:
- If you require cabinet-type cladding for your unit, consult your recognised expert technician company.
Under no circumstances must you enclose your device
arbitrarily. Enclosing the appliance in a cabinet requires observance of special design instructions.
For alterations to the appliance or to its environment,
you must refer to the suitably qualified heating engineer which is responsible for it.

Safety 2
Caution!
a
Inappropriate alterations can cause damage!
Under no circumstances should you attempt to
make alterations to the gas wall-mounted boiler
or other parts of the system.
Never try to carry out maintenance work or repairs on the appliance yourself.
• Do not damage or remove seals on components. Only
a suitably qualified heating engineer or our customer
service may remove sealed components.
Danger!
H
Risk of scalding!
The water coming out of the tap can be very
hot.
Caution!
a
Risk of damage!
Do not use sprays, solvents, chlorinated cleaning agents, paint, adhesives or similar substances in the vicinity of the appliance. These
substances can cause corrosion, even in the
flue system.
Installation and setting
Caution!
a
Installation of the unit may only be undertaken
by a recognised specialised technician in accordance with "Gas Safety (Installation and
Use) Regulations 1998".
In IE the installation must comply with the current Version of I.S.813 ‘Domestic Gas Installations’ (gas installations in private households)
and the current Building Regulations. The current ETCI Regulations for the installation of
electrical equipment must also be observed.
If you wish to keep the unit ready for operation using an
emergency generating set in the event of a power failure, the technical specification of the unit (frequency,
voltage, earthing) must match the power mains, and
must correspond at least to the power consumption of
your unit. Contact your expert technician company for
advice.
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!
a
Risk of damage!
If there is a power cut or if the room temperature is set too low in individual rooms it can
not be ruled out that sections of the heating
system are damaged by frost.
Always observe the information on frost protection provided in Chapter 4.9.
Caution!
a
The unit may only be operated continuously
with its cladding properly closed! Otherwise,
under unfavourable conditions, it can result in
material damage or even injury or death.
Filling pressure of the heating system
Regularly check the filling pressure of the heating installation, see Chapter 4.7.4.
Emergency power supply
Your heating engineer connected your gas wall-mounted heating device to the mains supply during installation.

3 Instructions on operation
3 Instructions on operation
3.1 Vaillant warranty
Vaillant provide a full parts and labour warranty for this
appliance.
The appliance must be installed by a suitably competent
person in accordance with the Gas Safety (Installation
and Use) Regulations 1998, and the manufacturer’s instructions. In the UK ‘CORGI’ registered installers undertake the work in compliance with safe and satisfactory
standards. All unvented domestic hot water cylinders
must be installed by a competent person to the prevailing building regulations at the time of installation. (G3)
Terms and conditions apply to the warranty, details of
which can be found on the warranty registration card
included with this appliance.
Failure to install and commission this appliance in compliance with the manufacturer’s instructions may invalidate the warranty (this does not affect the customer’s
statutory rights).
3.2 Intended use
The Valliant atmo ecoTEC wall boilers are state-of-theart appliances which have been constructed in accordance with recognised safety regulations. Nevertheless,
there is still a risk of injury or death 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.
This unit is not intended for use by persons (including
children) having limited physical, sensory or mental capacities or who have inadequate experience and/or
knowledge, unless supervised by a person responsible
for their safety or who has been given instructions from
them as to how to operate the unit. Children must be
watched to ensure that they do not play with the unit.
The units are intended as heat generators for closed
hot-water central heating installations and for central
hot water preparation. Any other or additional 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.
3.3 Requirements of the installation site
The Valliant ecoTEC gas wall boilers are installed on the
wall so that condensation can be diverted and so that
the flue system pipes can be laid.
They can be installed in basements, storage rooms, utility rooms or living areas. Ask your heating engineer
which national regulations must be observed.
Note!
h
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.
3.4 Care
• Clean the cladding of your unit with a damp cloth and
a little soap.
Caution!
a
Risk of damage
Do not use scouring or cleaning agents which
might damage the cladding, fittings or controls.
Do not use sprays, solvents or cleaning agents
containing chlorine.
3.5 Recycling and disposal
Both your Valliant ecoTEC gas wall boiler and its packaging consist mainly of recyclable raw materials.
3.5.1 Appliance
Do not dispose of your Valliant ecoTEC gas-fired wallmounted unit or any of its accessories in the 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 appliance.
Note!
h
Please observe the applicable national legal
regulations.
Caution!
a
Any improper use is forbidden.
