of ATAG units. It is advisable to read these instructions
thoroughly, well in advance of installation. Separate
instructions for use are supplied with the unit for users of
ATAG central heating units. ATAG is not liable for the
consequences of mistakes or shortcomings which have
found their way into the installation instructions or users
manual. Further, ATAG reserves the right to alter its
products without prior notification.

When delivering the unit, give the customer
clear instructions concerning its use; present
the customer with the users manual and card.

Each unit is fitted with an identification plate. Consult the
details on this plate to verify whether the unit is compliant
with its intended location, e.g.: gas type, power source
and exhaust classification.

On completion of the installation the installer or
commissioning engineer must fill out and complete the
Benchmark commission section of the boiler log book and
hand to customer or end user for future record keeping. The
Benchmark log book must also be filled out and completed
by the service agent following each service call, and returned
to the customer. A copy of the Benchmark commissioning
certificate must be returned to ATAG Heating UK Ltd / Total
Energy Management Ltd along with the warranty registration
card to register the appliance for the standard warranty
benefits.

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.

The boiler has been tested 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
emission of damaging substances is far below the standard
set for equipment with the gas quality-control label for clean
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;

Installation instructions E-SHR series page 6

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
difference between the flow and return water is checked. 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.

H(m)

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 pre­charge pressure of 1 bar and a capacity of 8 litres.
The vessel of the E-SHR35T is positioned directly beneath
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, choose an
expansion vessel volume, 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.
