The Benchmark Scheme
ATAG Heating Technology 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, efciency 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 completed 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 Regulations
(England and Wales).
All installations must be notied to Local Area Building Control either directly
or through a Competent Persons Scheme. A Building Regulations Compliance
Certicate 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 optimise its safety, efciency 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.

2 Safety
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 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
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 Technology Ltd.

3 Boiler description
The ATAG i-Range boiler 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 >88% Efcient SEDBUK 2009 rated.

4.2 Eco function DHW (iC-Range only)
With the ECO button you can select DHW ECO mode or
DHW Comfort mode.
(DHW program must be on; visible on display)
Press ECO-button briey:
- ECO mode is on when symbol is visible on display.
- Comfort mode is on when ECO symbol is not visible on display.
From factory the boiler is set to Comfort mode. This mode keeps the DHW
facility on 50°C. The advantage is that the boiler produces hot water almost
instantaneously when hot water is tapped.
When ECO mode is selected it will take a few seconds longer before the hot
water runs from the opened xture.
4.3 Requesting current boiler data (info mode)
Press the eco-button for 6 seconds in order to obtain the
following current boiler data using the scroll buttons:
A0 Flow water temperature in °C
A1 Return water temperature in °C
A2 DHW temperature in °C (only iC-Range)
A3 Calculated ow temperature (T-set) in °C
A4 Flue gas temperature (only if a ue gas sensor is connected) in °C
A5 Outside temperature (only if an outside sensor is connected) in °C
A6 Water pressure in °C (only iC and iS-Range)
A7 DHW ow in l/min. (only iC-Range)
A8 Ionisation current in mA
A9 Revolutions of the fan in rpm
To return to the standard view press ESC.

4.4 Reset-button
The reset button allows the boiler to restart if an error has
occurred.
In case of an error the symbol is displayed with a
XXX code.
In other cases the reset button does not function and will
not respond to operation.
See chapter XX for a brief overview of error codes.
4.5 Frost protection
The iC and iS-Range boiler control is from standard provided with a boiler frost
protection.
The frost protection is switched on automatically when the symbol in the
display is ashing and the pump is running.
In case there is danger of frost of the rest of the heating
system the frost protection can be switched on manually
by pressing the two - buttons for 6 seconds.
The symbol is constant in the display and the pump is
running constantly.
Press both - buttons again for 6 seconds to switch back to
automatic.

5 Filling the heating system
Information on the water pressure:
The default view of the display shows OK. Press the eco-button for
6 seconds and press the eco-button a few times more until A6 is
displayed. The actual water pressure will be shown:
Water pressure too low
Code 118 and spanner symbol visible:
Water pressure is too low (<1.0 bar)*.
Power is reduced by 20%. The installation should be relled.
or
Code 118 and spanner symbol visible:
Water pressure is too low (<0.7 bar)*.
The boiler is taken out of operation. The installation should be relled.
After the installation has been relled and if the pressure was below
0.7 bar the de-aeration program will start (Code 105 and spanner
symbol visible). This will last for approximately 7 minutes.
Water pressure too high
Code 117 and spanner symbol visible:
Water pressure is too high (> 3.0 bar)*.
The boiler is taken out of operation.
The installation pressure should be reduced by draining water from the heating system.

Filling procedure
Combi boiler (iC-Range):
The iC-Range boiler is provided with a lling
loop.
Connect the lling loop between cold water
connection (1) and CH connection (2)
- Open slowly the valves (A and B) of the
lling loop;
- Read the water pressure from the pressure
gauge under the boiler or from the display
according to the procedure described
above and wait until the pressure reaches
between 1.7 and 2 bar;
- Close both valves (A and B) of the lling
loop.
Always disconnect the lling loop and close
the valves with the cap nut (3).
System boiler (iS-Range)
The heating system connected to the iS-Range boiler is provided with a lling
loop.
Connect the lling loop between cold water tap and the connection on the heating
system
- Open slowly the valves of the lling loop
- Read the water pressure from the pressure gauge under the boiler or from
the display according to the procedure described above and wait until the
pressure reaches 1.7 bar.
- Close both valves of the lling loop
Always disconnect the lling loop.
Regular boiler (iR-Range)
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 1 05) of approx. 7 minutes has ended, the boiler
will be operational again.

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.
