3 Description of the appliance
The ATAG Premier E-SHR boiler is a room sealed,
condensing and modulating central heating boiler, with or
without an integrated hot water facility.
The built-in fan sucks the combustion air from outside and
provides full premixing of the gas and air. The gas mixture
is guided through the ceramic burner which is fitted above
the heat exchanger. As a result of the small flame height
a compact construction is possible. The combustion
gasses are exhausted after passing through the stainless
steel heat exchanger. The formed condensate water is
discharged through the waste trap.
Theboilerhasbeentested according to valid CE* standards
and has a CE* certificate and SEDBUK A-rating.
The operating efficiency of the boiler is higher than 98% (on
upper value Hs). As a result of its compact construction the
radiation, convection and stand by losses are very low. The
emissionof damaging substances is farbelowthe standard
setfor equipment with thegas quality-control label forclean
combustion.
The boiler is provided with an automatic venting program.
In case of a recently topped up or filled up installation this
program takes care of the removal of any present air in the
boiler. In this case the control will check the water pressure
and if it is too low, will report this on the display.
The boiler anticipates the heat requirement of the central
heating installation or the hot water supply. As a result the
boiler will adjust its capacity to the installation and will
switch on less often, which means that the boiler will
operate longer and at a low level. It is possible that the
boiler will only have to switch on once an hour. In this case
the aim is to obtain maximum comfort and efficiency.
In order to be able to anticipate installation heat
emissions the boiler has been fitted with a proportional
gradient control system. After the boiler goes into
operation this control provides a uniform increase of
power, instead of immediately burning at full power. When
the installation does require full power the control will
adjust as required. By this means a uniform increase of
the water temperature is effected.
If an outside sensor is connected, the control will operate
weather-dependent. This means that the control
measures the outside temperature and the flow water
temperature. On the basis of this data the control
calculates the optimal flow water temperature in the
installation.
The E-SHR-T combination boiler provides a hot water
supply by means of a plate heat exchanger fitted in the
boiler and provides a constant hot water temperature of
60°C (factory setting). A heat retention device ensures a
minimum temperature of 30°C of the plate heat exchanger,
which benefits comfort.
4 Scope of the supply
The boiler is supplied ready for use. The supply kit is
composed as follows:
- Boiler with casing;
- Automatic vent (inside the boiler);
- Safety valve (inside the boiler);
- Suspension bracket
- Adapter fittings
- Fixing material consisting of plugs and screws;
- Template;

5.1 Dimensions
5 Mounting of the boiler
The boiler can be mounted practically to any wall with the
suspension bracket and the included fixing equipment.
The wall must be flat and of sufficient strength in order to
be able to carry the boiler weight.
Above the boiler there must be at least 250 mm working
space in order to be able to fit a twin supply and exhaust
system or a coaxial flue system. On both sides of the
boiler at least 10 mm must be reserved in connection with
fitting or removing of the casing. The location of the boiler
can be determined by using the template.
Remove the casing of the boiler. The casing is also the
airbox of the boiler and is secured with a screw behind the
door at the front. Also the four quick-release fasteners (2
at the top and 2 at the bottom) should be secured with a
screw.
First remove the screws before loosening the
quick-release fasteners.
Tighten the screws again when replacing the
housing.
Lift the boiler only at the boilers rear wall.

6.1 Central heating system
The boiler pipes can be connected to the installation by
means of compression fittings. Reducers should be used
for connecting to thick-walled pipe (welded or threaded).
The boiler has a self-adjusting and self-protecting control
system for the load capacity. By this means the temperature
differencebetween the flow and returnwaterischecked. The
circulation pump will be able to supply the given water
displacement with an installation resistance of up to 18 kPa,
for this see table 3.
If the capacity of the boiler pump is insufficient, an extra
external pump can be installed in series with the boiler.
The electrical side of this external circulation pump can
be connected in the Control Tower, by which means this
pump switches at the same times as the boiler pump.
The maximum absorbed current consumption of the
external circulation pump may be 230 W (1 Amp).
If the installation resistance is higher than the stated value
the load will be adjusted until an acceptable temperature
difference between flow and return water has been
obtained. If, after this, the temperature difference remains
too much then the boiler will switch itself off and wait until
an acceptable temperature has arisen.
If an unacceptable temperature is detected, then the
control will repeatedly try to achieve water flow, and if this
does not work then the boiler will switch off.

As standard the boiler is provided with a water filter in the
return pipe of the boiler. With this, possible contamination
of the central heating water is prevented from ending up
in the boiler. The boiler is also provided with an internal
safety valve set at 3 bar. This is connected by means of
a combination waste to the condensate discharge.
If all, or a large number of radiators are provided
with thermostatic radiator valves it is advisable to
use a pressure difference control (bypass) in order to
prevent flow problems in the installation.
The boiler is designed to be used on sealed
system only.
Additives in the installation water are only
permitted in consultation with the country
distributor.

6.2 Expansion vessel
All ATAG Premier boilers are provided with an internal
expansion vessel.
The vessel of the E-SHR 15, 24 and 24T is positioned
inside the boiler casing. this expansion vessel has a pre-
charge pressure of 1 bar and a capacity of 8 litres.
The vessel of the E-SHR35T is positioned directlybeneath
the boiler and together with the casing forms a single entity
with the boiler.
The expansion vessel is located vertically behind the
casing, which can be removed by pulling forwards. The
expansion vessel has a pre-charge pressure of 1 bar and
a capacity of 12 litres.
If a larger capacity expansion vessel is needed for the
installation a standard expansion vessel should be fitted
additionally.
If the internal expansion vessel is not sufficient, choosean
expansion vesselvolume, of which the summary is geared
to the installation’s water capacity. The pre-charge
pressure depends on the installation height above the
expansion vessel (Table 4). Fit the expansion vessel into
the return pipe as close as possible to the boiler.
6.4 Gas connection
The appliance pipe is fitted with an internal thread, into
which the tail piece of the gas tap can be screwed.
United Kingdom:
The gas supply must comply to the current Gas Safety
Regulations.
Ireland:
- Irish standard 813
- Domestic gas installations
The connection to the appliance must include a suitable
method of disconnection and a gas control cock must be
installed adjacent to the appliance for isolation purposes.
The nominal inlet working gas pressure measured at the
appliance should be 20 mbar for Nat gas (G20).
Make sure that the gas pipe work does not
contain dirt, particularly with new pipes.
6.5 Hot water supply E-SHR 24T and 35T
The ATAG Premier E-SHR 24T and 35T are fitted with a
stainless steel plate exchanger for producing domestic
hot water. The boiler does not have a hot water store and
in case of a demand for hot water the boiler will heat the
sanitary water flowing through the plate heat exchanger
up to 63°C instantanious.
The water mains installation must comply with the water
BYE-laws.
In regions with a water hardness value higher
than 15°D, calcium deposits should be
removed from the plate heat exchanger on a
regular basis. If problems occur when using
sanitary water with a chlorine content higher
than 150 mg/l, no recourse can be made to the
terms of the warranty.
The hardness of the water is variable in the United
Kingdom and Ireland. The water company can provide
exact information about this.
The cold and hot water pipes can be connected to the
installation by means of compression fittings.
The cold water inlet on the E-SHR-T boilers must be
provided with the following (counted in the water flow
direction):
- Safety group;
- Expansion vessel for potable water, 6 bar (blue)
6.3 Underfloor heating system (plastic pipes)
When connecting or using an underfloor heating system,
designed with plastic pipes, or plastic pipes are used
elsewhere in the installation, one should ensure that the
plastic pipes used comply with the DIN 4726/4729
standard. It is set out in this standard that the pipes may
not have oxygen permeability higher than 0.1 g/m³.d at
40°C. If the system does not comply with this DIN
standard, the underfloor heating component will have to
be separated from the central heating boiler by means of
a plate exchanger.
No recourse can be made to the terms of the
warranty in the event of failure to observe the
regulations pertaining to plastic underfloor
heating pipes.

6.6 Hot water supply E-SHR 15 and 24
Depending of the comfort preferences different external
hot water cylinders can be connected to E-SHR 15 and
24 solo boiler. The choice of the cylinder depends on the
coil output. The coil output must be compatible with the
boiler output. The E-SHR 15 and 24 are provided with an
internal DHW control. The electrical connection can be
made on the connection terminal in the Control Tower.
See the wiring diagram on page 13 and 14.
6.7 Condensation drain pipe
The collective condensation drain pipe should be
connected to the drain by means of an open connection
(Tundish Break). Removing the possibility of foul drain
gases and water backing up into the boiler. The drain
connection should have a minimum diameter of 25 mm.
The following components are connected to the combi-
nation condensation drain pipe:
- Condensation discharge;
- Safety valve;
Draining of the condensation water to the
external rain guttering is not permitted in
view of the danger of freezing.
Before putting the boiler into operation fill the
siphon with 300 ml of water.
6.8 Flue gas exhaust system and air supply
system
Theappliance connection diameter is80/125 mm, to which
the flue gas outlet and air supply system can be fitted, with
or without elbow pieces. The maximum permissible pipe
length is set out in Table 5.
United Kingdom:
The flue gas outlet and air supply installation must
comply with the current regulation requirements. IG UP
10 and BS 715.
Ireland:
- Irish standard is 813 section 9.10.1
We recommend that you use a stainless steel flue gas
outlet material. Using the ATAG icicle-free roof outlet
prevents ice from building up on the roof outlet.
Before connecting any
flue pipe or fittings into
the adaptor (1), Please
remove both flue gas
test nipples, items 2 &
3. Make flue or fitting
connection, Re-
connect both flue gas test nipples.
Flue systems must comply with the current regulations.
It is essential that in practice, products of combustion
discharging from the terminal cannot re- enter the building
or any other adjacent building through ventilators,
windows, doors, other sources of natural or mechanical air
infiltration from forced ventilation or air conditioning
systems.
Horizontal sections of flue sections of the flue system
should always be installed sloping towards the boiler, in
order to avoid condensate lying in the flue system.
The minimum gradient is 30mm/mtr. With the condensate
running back to the boiler the risk of ice forming at the
terminal is reduced.

The terminal should be located where dispersal of
combustion products is not impeded and with due regard
for the damage or discolouration that might occur to
building products in the vicinity (see fig 10).
In certain weather conditions condensation may also
accumulate on the outside of the air inlet pipe. Such
conditions must be considered and where necessary
insulation of the inlet pipe may be required.
In cold and/or humid weather water vapour may condense
on leaving the flue terminal. The effect of pluming steam
must be considered.
The terminal must not be located in a place where it is
likely to cause a nuisance.
For protection of combustibles, refer to IS 813 section
9.10.1. where the terminal is less than 2m (6.6ft) above a
pavement or platform to which people have access
(including) any balcony or flat roof the terminal must be
protected by a guard of durable material.
A suitable guard is available from the country distributor.
Where a terminal is fitted below a window
which is hinged at the top, and where the
hinge axis is horizontal, and the window
opens outwards, the terminal shall be 1m
below the bottom of the window opening.
If the boiler is to be located under stairs, a
smoke alarm meeting the requirements of I.S.
409 or equivalent must be fitted.
The flue must be terminated in a place not
likely to cause a nuisance.
For horizontal sections, the outlet system should always
be fitted on an incline (30 mm/m) sloping down towards
the appliance so that no condensation water is able to
accumulate in the outlet system. The chances of icicles
forming on the roof outlet is minimised by causing the
condensation water to run back towards the appliance. In
the case of horizontal outlets the inlet system should be
fitted on an incline sloping down towards the outside to
prevent rainwater from coming in.
Fitting an additional condensation collection device in the
outlet system is surplus to requirement.
The appliance produces a white wisp of condensation.
This wisp of condensation is harmless, but can be found
to be unpleasant, particularly in the case of outlets in
outside walls.

range of the exhaust and supply system
please contact the country distributor.
6.9 Air supply
It is NOT necessary to have a purpose provided air vent in
the room or internal space in which the boiler is installed.
Neither is it necessary to ventilate a cupboard or
compartment in which the boiler is installed, due to the
extremely low surface temperature of the boiler casing
during operation. Therefore the requirements of BS 6798,
Clause 12, and BS5440:2 may be disregarded.
The appliance is not suitable as an "open"
appliance. This means that combustion air
should always be obtained through a direct
connection.

When using an on/off thermostat or control, it is possible
that an anticipating resistance must be installed in order
to prevent too high temperature fluctuations. As a stand-
ard rule this means mercury thermostats. This resis-
tance wire is present in the Control Tower and must be
connected to clamps 23 and 27. The anticipating resis-
tance in the room thermostat has to be set at 0.11 A.

8 Boiler controls
Theboiler is provided withafully automatic microprocessor
control. This control simplifies operation by undertaking all
major control functions. Initially when power to the unit is
switched on it will remain on standby. The control panel
display will show the relevant state. The various parame-
ters can be called up in two ways:
The state.
In this state the display will show during all normal
operating functions of the appliance. Should a fault
develop this will be shown on the display.
The technical read out.
Start from the state by pressing the Step key for
5 seconds. Returning from this to the display is
done in the same way. From the technical read out a more
extensive read out can be obtained e.g. the boiler flow
temperature and the water pressure in the central heating
system.
When the system has been filled and the automatic venting
program starts, when a program has been selected, the
program takes 15 minutes and stops automatically. After
this the unit will function normally.
On a call for heating or hot water the control system will
select the required water control temperature. This water
temperature is called the T-set value. On a call for central
heating the boiler ignites first at low input. The input is then
changed slowly to match the load required. The boiler
operates in this way to avoid excessive water noises and
temperature overshoot. On a call for hot water supply the
T-set value of central heating return water temperature is
monitored. Depending on the amount of sanitary water
which is withdrawn from the DHW facility, the central
heating return water temperature, from which the input is
adjusted, will vary.
8.1 Explanation of the function keys
Key functions from the and the extensive
indication are:
-Central Heating program key, see chapter 9.1;
-Hot Water program key, see chapter 9.2;
-PC program key, adjusts the pump to continuous
water circulation in the central heating system, or
according to the pump overrun times on the relevant
programs;
- Step key, after briefly pressing, the water pressure
can be retrieved and pages per chapter can be
retrieved. After pressing for 5 seconds it switches from
indication to technical indication and the other
way round;
- Mode key, after briefly pressing, a selection of the
data chapters can be retrieved. After pressing for 5
seconds it is possible to enter the code as described
in chapter 9.3;
- Reset key, after briefly pressing, for:
unlocking errors;
ending the access code;
ending the automatic venting program, only when the
access code is entered and the reset key is pressed
briefly.
After pressing for 5 seconds an operating stop is
made, for example, for activating the automatic
venting program.
Other key functions from the other indications are:
-Central Heating key then has the + function;
-Hot Water key then has the - function;
-PC key then has the store function, which means
that by means of this key a modified setting is
confirmed;
- Step key for scrolling in a data chapter.

9 Filling and venting the boiler
and installation
Filling of the system is carried out in the normal way. In
order to read out the central heating water pressure the
electrical supply must be switched on.
The circulation pump will not begin to operate as long as
the operating lamps are off. The control display will show
a indication, which means that the control is
signalling insufficient water pressure. If the installation is
filled and the water pressure rises then the water pressure
will automatically be shown with an alternating text.
Ifthe water pressure risestoabove 1.5 bar thenaftera short
“stop” text the indication will appear, which means
the water pressure is sufficient and the boiler is ready for
operation.
In order to be able to read out a constant water pressure the
Step key should be pressed in and in order to obtain a
constant readout the Step key should be pressed
briefly again.
If the water pressure in the boiler becomes to high (>2,8
bar) a text appears, by which means the burner is
switched off. After draining the water from the installation,
by which means the water pressure arrives below 2,5 bar,
the text disappears and the burner is activated.
In order to go from a read-out to a technical
readout the Step key should be pressed for 5 seconds.
This read-out can be selected if the user requires a
technical read out. In order to return to the read-
out the Step key must be pressed again for 5 seconds.
9.1 Central heating system
To fill the central heating system use the filling and drain
valveprovided.
Fill the system as follows.
- Turn on the electrical supply and leave the operational
lamps off;
- Connect the mains filling loop (not supplied);
- Open the cold water supply tap on the filling loop and
allow the system to fill slowly;
- The boiler has an automatic vent which removes the air
which is present;
- Bring the installation pressure up to between 1.5 and
2.0 bar after all radiators and pipes have been vented;
- Close the mains filling loops main inlet tap, remove
filling loop and cap supplies;
- Activate the automatic venting program by pressing
the pump key which means the pump lamp will be
illuminated. Allow the control to finish its venting
program. The pump will circulate a number of times
around the boiler as well as the central heating
installation.
Also, if a three-way valve is present, this will be
adjusted to the boiler and central heating installation
a number of times. The pump will be stopped regularly
in order to allow possible present air to escape.
- Check the water pressure and if required top up. The
working pressure in the installation should be between
1.5 and 2 bar in cold state.
- After finishing the automatic venting program the key
can be switched off again.
It can take several days before all the air is
removed from a freshly filled installation.
Especially in the first week noises can be
heard which indicate the presence of air. The
automatic air vent in the boiler will eventually
remove the air, from the system during this
period the water pressure in the system may
be deduced, if so it would be necessary to top
up the system with water to the nominal
pressure (1.5-2.0 bar) when cold.
9.2 Hot water supply
Open the main cold water supply valve to the DHW facility
and open the safety group.
Vent the plate exchanger and the hot water installation by
opening a hot water tap. Leave the tap open for as long as
required until all air has disappeared from the cylinder and
the pipes and only water is flowing from the tap.

Installation instructions E-SHR series page 17
10 Commissioning the boiler
Before the boiler is fired, ensure that the boiler and the
system are well vented and free of air. Purge the gas line
between the gas meter and the boiler and carry out a gas
soundness test as specified in the current Gas Safety
Regulations.
The boiler does not require adjustment of the burner
pressure and air quantity because it is self adjusting and
is factory set at the correct value.
10.1 Central Heating system
Provided there is a heat requirement from the thermostat
or control, the central heating program will be put into
operation by means of the key (central heating
program). The circulation pump will start circulating and
the boiler will start the burner.
10.2 Hot water supply
Provided there is a heat requirement from the cylinder the
hot water program will be put into operation by means of
the key (hot water program).
10.3 Adjustments
In the Control Tower a number of adjustments can be
made. These adjustments can be fed in easily by means
of the keys on the boiler. However, a distinction is made
between adjustments which are done by the user and
adjustments done by the installer.
At users level adjustments can only be made from the
technical read-out in other words from the display read-
out with the operating function and the water temperature.
Adjustments can not be made from the indication.
The next two chapters are accessible after pressing the
Mode key:
Chapter 1
The normal operating functions such as the simple
read out or the technical with the
read out.
Chapter 2
The chapter in which adjustments can be made.
