1 Introduction

These instructions describe the functioning, installation,
use and primary maintenance of ATAG central heating
units for United Kingdom and Ireland. Where necessary
different regulations of each country are separately
described.

These instructions are intended for the use of Corgi
registerd installers or registered Bord Gais installers in
connection with the installation and putting into operation
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.

The ATAG Premier boiler is a certified appliance and must
not be modified or installed in any way contrary to this
Installation Manual.
Manufactures instructions must not be taken in any way
as overriding statutory obligations.

The ATAG Premier is a central heating unit with an
optional integrated hot water function. These units must
be connected according to these instructions and all
installation norms in respect of the part of the unit to be
connected.

Observe the following rules of safety:

- All work on the unit must take place in a dry
environment.

- ATAG units must never be in operation without their

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;

- Benchmark logbook.

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.

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.

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 combi­nation 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

The appliance connection diameter is 80/125 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, Re­connect 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.

For further information regarding the supply
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.

8 Boiler controls

The boiler is provided with a fully 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 parame­ters 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.

Installation instructions E-SHR series page 16

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.
If the water pressure rises to above 1.5 bar then after a 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 read­out 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
valve provided.

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 read­out 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.

Green key function
The green key function can be used in order to activate the
factory settings. By this means the modified settings are
cancelled. The following actions must be carried out.

Make sure that chapter

is shown in the display by
means of the Mode key. After this press the Store key.
The word Copy becomes visible and the factory settings
will be active again.

11 Isolating the boiler

In some situations it may be that the entire boiler must be
switched off. By switching off the three keys with the
lamps for central heating, hot water and pump program,
the boiler is switched off. Leave the plug in the wall socket,
by which means the circulation pump and the three-way
valve are activated once every 24 hours in order to prevent
jamming.

In the event of frost danger it is advisable to
drain the boiler and/or the installation.

Installation instructions E-SHR series page 21

12 Commissioning

Work on the boiler must be carried out by a
competent person, (Ref: Gas Safety
Installation and Use ) using correctly
calibrated instruments with current test
certification.

The casing is fixed by 4 quick release clamps and 5
screws (4x 1 clamp and 1 behind door). After removing the
screw, unlock the clamps, now the casing can be
removed.

With the E-SHR settings such as burner pressure and
adjustment of the air quantity are unnecessary, due to the
fact that the boiler operates with a so-called zero pressure
control. By this means the correct gas quantity is
controlled by the suction operation of the fan. The fine
adjustment which is carried out at the factory is once­only, which means that adjusting of these values is
unnecessary.

Following maintenance or other activities;
always check the installation of all parts through
which gas flows (using leak-search spray).

12.1 Checking for contamination

In order to be able to check the boiler for
contamination in the following running years
it is advisable to measure the maximum air
displacement in the boiler when putting the
boiler into operation. This value can be diffe­rent with each type of boiler.

In order to be able to measure this value the following
operations must be carried out:

- in order to enter the service chapter feed in the access
code as described on page 18-20;

- select the manual fan setting without burner action
Step , by means of the Step key which will
indicate that the fan is off ;

- connect the digital pressure gauge hose to the
uppermost measuring nipple of the gas block
according to figure 13 (open it before fitting the hose);

- take the fan to its maximum number of revolutions by
means of the + key;

- measure the pressure difference and write down this
value;

- when next servicing the boiler the value of the fan
output may not have reduced by more that 20%
compared to the value during commissioning. If this
value is lower than 20% the boiler does not require
maintenance.

measuring point air pressure difference figure 13

Installation instructions E-SHR series page 22

13 Maintenance

Maintenance or changes to the unit may only
be carried out by an authorised technician.

13.1 The frequency of maintenance

We advise to carry out an inspection to the boiler every
two years and an overhaul every four years. When doing
this the circumstances of the boiler’s location must be
taken into account, From this one can determine whether
to deviate from this advice.

13.2 Maintenance activities

If it is necessary to clean the boiler the following actions
to the following components must be carried out:

The air unit (casing of the boiler)
Dirt which is sucked in by the air supply pipe will end up
at the bottom of the casing. This dirt can be cleaned with
a cloth with a simple (non-abrasive) cleaning agent.

The burner ceramic bricks and heat exchanger
These components should only be cleaned if it is
determined that the maximum Pa is no longer obtained as
described in chapter 12.1.

The fan unit must be removed in order to be
able to inspect the heat exchanger.

In this case the following actions must be carried out:

- close the gas valve and isolate the boilers electrical
supply;

- loosen the nut of the gas pipe under the gas block;

- loosen the small crosshead screw on the red
electrical connection adaptor of the gas block;

- remove the electrical connection plug from the fan
motor;

- loosen the front crosshead screw of the black plastic
air inlet damper;

- after this turn the two clamping rods ¼ turn and remove
them by pulling them forward;

- slightly lift the fan unit and remove it towards the front
of the heat exchanger;

- the fan unit and the air inlet damper can be checked
for contamination and if necessary cleaned;

- now remove the burner ceramic bricks by slightly
lifting them upward and removing them in the same
direction as the heat exchanger fan unit;

- the burner ceramic bricks and the heat exchanger can
be cleaned by means of a soft brush;

Do not flush the heatexchanger through with
water

Refitting of the components is done in reverse.

12.2 Checking the CO

2

The CO2 percentage is factory-set. This has to
be checked during check up, service and
error intervalls.

- remove the black cover from the gas valve by means
of unscrewing the by paint sealed screw.

- put the boiler into operation by means of the service
chapter as described in chapter 10.3;

- place the lance of the CO2 gauge in the location
according to figure 14;

adjustment screw CO

figure 14

- adjust to maximum load by means of the “+” key;

- ending the manual selection is done by pressing the
“-” key until the minimum load is shown. After pressing

this key again the text is shown which means
that the selection is off.

- adjust the CO2 percentage according to table 12. The
CO2 percentage can be adjusted by means of the
adjustment screw according to figure 15.

- replace the black cover and tihgten it with the screw.

Installation instructions E-SHR series page 23

The following components require extra attention during the
service procedure and when dismantling and reassenbling
the burner:

- ensure that the orange gasket that fits around the
ceramic brick has not heat hardened or perished in any
way, if it has, it is essential that the gasket is replaced
before continuing to reassemble the boiler. If in any
doubt replace the gasket;

- make sure that the burner gasket is fitted onto the heat
exchanger precisely;

- make sure that the fan unit clamping rods have been
pushed backward sufficiently and that they have again
been turned ¼ turn;

- make sure that the gas connection under the gas block
is tightened;

Following maintenance or other activities;
always check the installation of all parts through
which gas flows (using leak-search spray).

The siphon
In order to check the siphon for contamination the
following actions must be carried out:

- make sure that the boiler is off by isolating the boilers
electrical supply;

- unscrew the screw in the bottom of the condensate
tray of the heat exchanger where the siphon is fixed;

- pull the siphon downwards until it is released from the
condensate tray;

- pull the drain pipe of the saftey valve out of the siphon;

- turn the siphon carefully out of the boiler;

- clean the siphon and re-fill with water.

Refitting is done in reverse order.

13.3 Further checks

Checking the ionisation current.

- ionisation determines if there is a flame present with
correct combustion. The measurement is done by means
of connecting a micro Ampere gauge in series with the
ionisation thread. The minimum allowed ionisation is 2 µA.
The boiler will modify its load anyway if the ionisation
reaches the bottom limit of 2 µA.

Checking by means of a visual inspection.

- A visual inspection entails viewing and checking of a
number of components with regard to their functioning.
The safety valve may not show any traces of leaks. The
waste trap should be clean.
The central heating water filter only requires cleaning if
the circulation pump is adjusted at maximum speed
and the maximum DT is exceeded.

Following maintenance or other activities,
always replace the housing and secure it with
the screws.

17 Error indication

When detected, errors are indicated on the display. Some, of a temporary nature, will not usually result in the boiler
locking out. Whilst the control system will try its utmost to prevent lockout, and may temporarily switch off the unit,
any fault which could potentially damage the appliance will result in lockout. The following are examples of message
display, which fall into two categories - i.e. Blocks and Errors.

Blocks with a number in the last 2 positions.

Block 01:

External safety contact cut out

Block 11:

Maximum DT of flow and return sensor in central heating has repeatedly been exceeded. During the
block normal operation of the hot water supply is possible. The pump continues to operate at minimum
capacity during the block.

Block 12:

Maximum DT of flow and return sensor in domestic hot water has repeatedly been exceeded. During
the block normal operation of the central heating installation is possible. During the block the pump
continues to operate at minimum capacity.

Block 60:

Incorrect parameter setting of the minimum or maximum power.

Block 67:

A DT has been detected between flow and return sensor whereas the burner is not in operation. After
the DT has disappeared the block will disappear.

Block 80:

Maximum flue gas temperature has been exceeded (if present). The block will not be cancelled until
the flue gas temperature has arrived below the temperature.

Block 81:

The flue gas sensor is not connected although it has been connected to the control. The burner is blocked
until the flue gas sensor is reconnected.

Block 82:

The flue gas sensor has short-circuited, heat requirement blocked and pump capacity at minimum.

Block 85:

The control has not detected a water flow. The venting cycle is started. If during this cycle water flow
is detected, the venting cycle is ended and the burner is released.

Error with a number in the last two positions.

Error 00: poor flame-forming
Error 01: short-circuit of 24 volt circuit

Error 02: no flame-forming
Error 03: temperature in airbox to high
Error 04: adjustment or error for voltage interruption
Error 05: fault control unit
Error 12: fuse 24 volt/3AT faulty
Error 19: maximum return temperature exceeded
Error 28: number of revolutions not reported back from fan
