The current, Electricity at Work Regulation must be complied with and also be in
accordancewiththerelevantand current editions of the British Standards.
TheATAGEboileris a certified appliance and must not be modified or installedinany
way contrary to this Installation Manual.
Manufacturers instructions must not be taken in any way as overriding statutory
obligations.
The ATAG E is a central heating boiler with an optional integrated hot water function.
These boilers must be connected according to these instructions and all installation
norms in respect of the part of the boiler to be connected.
Observe the following rules of safety:
- All work on the boiler must take place in a dry environment.
- ATAGboilersmayneverbeinoperationwithouttheirhousing,exceptinconnection
with maintenance or adjustments (see Chapter 13 and 14).
- Never allow electrical or electronic components to come into contact with water.
Carry out the following tasks in connection with maintenance, etc. to an already-
installedboiler:
- Shutdownallprograms
- Close the gas tap
- Remove the plug from the wall socket
- Close the stop cock of the boiler’s intake connection
Take note of the following when maintenance or adjustments are needed:
- Theboilermustbeabletofunctionduringtheseactivities;forthisreason,theboiler’s
supplyvoltage,gaspressureandwaterpressuremustbemaintained.Ensurethat
there is not a source of potential danger during these activities.
Following maintenance or other activities; always check the installation of all
parts through which gas flows (using leak-search spray).
Following maintenance or other activities, always replace the housing and
secure it with the screw behind the door at the front of the casing.
The following (safety) symbols may be encountered in these installation instructions
andontheboiler:
This symbol indicates that the boiler must be stored away from frost.
This symbol indicates that the packaging and/or contents can be damaged as
a result of insufficient care taken during transport.
This symbol indicates that, whilst still in its packaging, the boiler must be
protected from weather conditions during transport and storage.

4 Description of the boiler
TheATAGEboilerisaroomsealed,condensing,modulatingcentralheatingboiler,with
orwithout an integratedhot waterfacility.
The boiler is provided with a compact stainless steel heat exchanger with smooth
tubes. A well thought out principal using durable materials.
The boiler burns gas for supplying warmth. The heat is transferred in the heat
exchangerto the waterinthecentralheating system. Bycoolingdowntheflue gasses
condensate is formed. This results in high efficiency. The condensate, which has no
effect on the heat exchanger and the function of the boiler, is drained through an
internal siphon.
The boiler is provided with an intelligent control system (CMS Control Management
System).Theboileranticipatestheheatdemandofthecentralheatingsystemorthehot
waterfacility.
When an outside sensor is connected, the boiler works weather dependantly. This
meansthattheboilercontrolmeasurestheoutsidetemperatureandflowtemperature.
With this data the boiler calculates the optimal flow temperature for the installation.

5 Mounting the boiler
Theroomwheretheboilerwillbeplacedmustalwaysbefrostfree.Theboilercasingis
splash water tight (IPX4D) and is suitable to be installed in e.g. a bathroom.
ItisNOTnecessarytohaveapurposeprovidedairventintheroomorinternalspacein
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
temperatureoftheboilercasingduringoperation.ThereforetherequirementsofBS6798,
Clause12,andBS5440:2maybedisregarded.
The boiler can be mounted practically to any wall with the suspension bracket and the
enclosedfixingequipment.Thewallmustbeflatandofsufficientstrengthinordertobeable
to carry the boiler weight with its water content.
Abovetheboilerthere must be at least 250 mmworkingspacein order to be able to fit
a coaxial flue system or a twin supply. On the left side of the boiler at least 50 mm and
on the right side 10 mm must be reserved to allow fitting or removing of casing. The
location of the boiler can be determined by using the template.
Removethecasingoftheboiler.Thecasingisalsotheairboxoftheboilerandissecured
withascrewbehindthedooratthefront.Alsothefourquick-releasefasteners(2atthe
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.
Lifting and carrying precautions:
- Lift only a manageable weight, or ask for help.
- Whenliftingtheboiler,bendtheknees,andkeepthebackstraightandfeetapart.
- Do not lift and twist at the same time.
- Lift and carry the boiler close to the body.
- Wearprotectiveclothing and glovestoprotectfromany sharp edges.
Removing the casing figure 1
Lift the boiler only by the boilers rear wall.

When the boiler has to be converted from natural gas to LPG, ATAG provides special
kits for this purpose. Special instructions are supplied with the kit.
Always check the installation of all of the parts through which gas flows
(using leak-search spray)

The water mains installation must comply with the British water regulations.
In regions with a water hardness value higher than 267ppm (2,67 mmol/l),
calcium deposits should be removed from the plate heat exchanger on a
regular basis. If problems occur when using sanitary water with a chlorine

6.6 Condensationdrainpipe
ATAG boilers produce condensate. This condensate must be drained otherwise the

Connect the condensation drain pipe according to the actual regulations.
The following components are connected to the collective 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.
The condensate pipe must be run using suitable corrosion resistant materials (eg.
plastic).

We suggest you design a simple flue gas system and air supply system using table 6.
For further information about the available components of the flue gas and air supply
system we recommend you consult the Monopass Flue system literature.
The ATAG flue gas system is meant and designed solely for the use on ATAG central
heating boilers adjusted to Nat gas or LPG. The maximum flue gas temperatures are
below70°C(fullload80/60°C)
Theproperoperation can be influencedharmfullybychangesofor adjustments to the
correct set up.
Possible warranty claims will not be honoured if incorrect changes result in non
compliance with the installation manual or local rules and regulations.

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.
Forhorizontalsections,theoutletsystemshouldalwaysbefittedonanincline(50mm/

accumulate in the outlet system. The chances of icicles forming on the roof outlet is
minimisedbycausingthecondensationwatertorunbacktowardstheappliance.Inthe
case of horizontal outlets the inlet system should be fitted on an incline sloping down
towards the outside to prevent rainwater from coming in.

Cutting the pipe goes as follows:
- Take out the inner tube by turning it until it releases from its security position;
- Cut just as much from the air intake part as from the flue gas part;
- Take off the burrs from the cutting edge to prevent cutting the seals;
- Click the pipes back together again.

and the correct diameter. The table below shows the maximum flue lengths with the
different boiler outputs. A longer flue gas length can be achieved by increasing the
diametertoø100mm.
Explanation table 1:
Two pipe flue gas system: maximum noted length = distance between boiler and
roof terminal A
Concentric flue gas system: maximum noted length = distance between boiler and
roof terminal B
When using bends the noted value behind every bend should be deducted from the
maximumstraightlength.

Example:
A 22kW with a
concentric flue gas system
ø60/100mm has according
to the table a maximum flue
straight length of 12m In the
system that is going to be
put in there are 2 x 45°
bends, so the maximum flue
gas length is
12 – ( 2 x -1 ) = 10 meters.

7 External hot water cylinders
Depending of the comfort preferences different external hot water cylinders can be
connected to the boiler. The choice of the cylinder depends on the coil output. The coil
output must comply with the boiler output.
