The Benchmark Scheme
ATAG Heating UK Ltd is a licensed member of
the Benchmark Scheme which aims to improve
the standards of installation and commissioning
of domestic heating and hot water systems in the
UK and to encourage regular servicing to optimise
safety, efciency and performance.
Benchmark is managed and promoted by the
Heating and Hotwater Industry Council. For more
information visit www.centralheating.co.uk
Please ensure that the installer has fully comple-
ted the Benchmark Checklist on the inside back
pages of the installation instructions supplied with
the product and that you have signed it to say that
you have received a full and clear explanation of
its operation. The installer is legally required to
complete a commissioning checklist as a means
of complying with the appropriate Building Regu-
lations (England and Wales).
All installations must be notied to Local Area
Building Control either directly or through a Com-
petent Persons Scheme. A Building Regulations
Compliance Certicate will then be issued to the
customer who should, on receipt, write the Noti-
cation Number on the Benchmark Checklist.
This product should be serviced regularly to opti-
mise its safety, efciency and performance. The
service engineer should complete the relevant
Service Record on the Benchmark Checklist after
each service.
The Benchmark Checklist may be required in the
event of any warranty work and as supporting
documentation relating to home improvements
in the optional documents section of the Home
Information Pack.“

Work on the installation should only be carried out
by qualied personnel with calibrated equipment.
When replacing parts, only ATAG Service
components may be used.
If you smell gas:
- No naked ames! No smoking!
- Do not switch lights on or off or use other
electrical switches.
- Do not use the phone
- Close the gas mains
- Open windows and doors
- Warn the occupants and leave the building
- Only call the gas company or installer once you
are outside the building.
Corrosion protection
Do not use sprays, chlorine-containing cleaning
products, solvents, paints etc. in the vicinity of the
device or its air supply. These substances have
an adverse impact on the device and can lead to
corrosion that may result in failures.
Checking the heating water
Regularly check the water pressure of the heating
installation
Always use potable water for lling the installation.
Adding chemical agents such as frost and
corrosion inhibitors are only to be added by your
installer.
If in doubt, check with your installer or ATAG
Heating UK Ltd (See contact details on page 25).
2 Safety
ATAG A-Serie

The ATAG A is a closed, condensing and
modulating CH boiler with or without an
integrated hot water supply which meets the
European standard (CE).
A declaration of conformity can be obtained from
the manufacturer.
The efficiency of the boiler is very high and
the radiation convection and standby losses
very low. The emission of noxious substances
is far below the fixed standards so the boiler is
SEDBUK Class A rated.

The boiler is equipped with a door at the front. After
opening the door you will nd a brief overview of
the meaning of all the keys and icons. These are
described below.
4 Display and function keys
4.1 Reset-key
The reset key restarts the boiler after a malfunction
has occurred.
In case of a failure the symbol is displayed

5 Filling the heating installation
If you want to top up the heating installation, proceed as follows:
(If in doubt, check with your installer)
1 Connect the lling hose to the cold water tap;
2 Fill the hose completely with drinking water;
3
Connect the lled hose to the lling and draining valve of the heating installation;
4 Open the lling and draining valve;
5 Open the cold water tap;
6 Slowly ll the CH installation to 1,5-1,7 bar:
Press the i-key until A6 appears (water pressure). The value on the display
increases;
7 Close the cold water tap;
8 The code C1 05 will appear on the display the moment the pressure
exceeds Venting program of approx. 7 min. becomes active;
9 Bleed the entire CH installation: start at the lowest point;
10 Check the water pressure and if necessary top off until 1.5 to 1.7 bar
11 Make sure the cold water tap and lling and draining valve are closed;
12 Disconnect the lling hose;
After the venting program (c1 05) of approx. 7 minutes has ended, the boiler
will be operational again.
Check the water pressure regularly and top it up if necessary. The operating
pressure in the system under cold conditions should be between 1.5 and 1.7
bar.
It may take some time before all the air has disappeared from a newly lled
installation. Especially in the rst week, sounds may be heard that indicate air. The
automatic air vent in the boiler will let this air escape, causing the water pressure
to drop during this period and water will need to be relled again.

In case of, for instance, a holiday:
Heating and hot water OFF:
Press the - key of both keys until the lowest value
has been reached. Release the key and press
the – key once again. The display is showing --.
The program has thus disabled. The arrow to the
left is off.
In case of work on the heating installation:
Make sure no heat request occurs: let no hot water
tap run and set the room thermostat to low. Pull
the plug from the wall socket. If the installation is
being drained, you have to take into account that
part of the heating water will remain in the boiler.
Make sure that the remaining heating water in the
boiler cannot freeze in case of frost.
