Work on the installation should only be carried out
by qualied 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

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
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.
2 Safety

ATAG A-Serie

The ATAG A is a closed, condensing and
modulating heating boiler 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.

5 Filling the heating system
This boiler is part of an 'Open Vent' heating
system. The system is not pressurized, but is
lled automatically by a lling system in the loft.
If there is a problem with this system, please
contact your installer.
When the heating system is lled and after a
power interruption the boiler will be reset and starts
with a venting program. After the venting program
(display shows c1 05) of approx. 7 minutes has
ended, the boiler will be operational again.

In case of, for instance, a holiday:
Heating OFF:
Press the - key of the key 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: 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.
6 Decommissioning the boiler

In the event of a failure (this is indicated by a c
and number code on the display) you can try to
eliminate the failure by pressing the Reset key. If
the failure persists, please contact your installer
as soon as possible and tell him the number code.
There are also messages with a c and a number
code that constitute no failures. These messages
will cancel themselves over time. Operating the
reset button has no effect then, for example:
c1 05 venting program active (approx. 7 min.)
If leaks occur in the installation, please contact
your installer.
Venting program active
Conclude a maintenance agreement with your
installer in order to have the installation periodically
checked and adjusted.
The cover of the boiler consists of plastic parts,
which can be cleaned with a normal (non-
aggressive) cleansing agent.
For the warranty conditions, see the Warranty
Card that has been delivered with the boiler.
