3 Notes on the installation and 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).
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.
3.2 Intended use
The Valliant atmoCRAFT gas boilers are state-of-the-art
appliances which have been constructed in accordance
with recognised safety regulations. Nevertheless, there
is a risk of injury or death to the user or others and
damage to the appliance or other property in the event
of misuse or use for which the appliance is not intended.
The units are intended as heat generators for closed and
open hot-water central heating installations and for
central hot water preparation. 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.
4 Operating manual atmoCRAFT
Notes on the installation and operation 3
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.
3.3 Requirements of the installation site
The Vaillant gas heating boilers atmoCRAFT 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
section 4.10 if you are unable to ensure this
requirement.
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.
3.4 Care
• Clean the exterior of your appliance with a damp cloth
and a little soap.
3.6 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. The desired heating and set-back
phases (e.g. at night) are automatically turned on and
off using the integrated time programmes.
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 programmes.
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.
Note!
Do not use scouring or cleaning agents, which
might damage the exterior or plastic controls.
3.5 Recycling and disposal
Both your Valliant atmoCRAFT gas boiler and its
packaging consist mainly of recyclable raw materials.
3.5.1 Appliance
Do not dispose of your Valliant atmoCRAFT gas 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
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.
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, 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
uncontrolled manner, i.e. heat energy is lost
inadvertently. The capacity of the radiator in this one
heated room is obviously not enough for such an
operating mode.
Consequently, the room cannot be heated adequately
and an uncomfortable feeling of coolness prevails (the
same effect is produced when doors between heated
and unheated or partially heated rooms remain open).
This is incorrect saving: The heating is in operation and
still the room temperature is not comfortably warm.
