3 Delivery package
The boiler is delivered ready for use. The delivery package is composed as follows:
• Boiler with cover;
• Automatic air vent (in boiler);
• Gas isolation valve;
• Suspension bracket;
• Cable feed through;
• Fittings consisting of plugs and screws;
• Drawing template;
• Installation instruction;
• User manual;
• Warranty Card and Benchmark logbook.
The ATAG A is mainly equipped with 230V electrical components.
The following components are not present in the boiler as a standard and should be
included in the installation according to the requirements (supplied by third parties):
• Circulation pump
• Programmer, room thermostat and cylinder thermostat.
4 Boiler description
The ATAG A is a room sealed, condensing and modulating CH boiler.
The boiler is equipped with a compact stainless steel heat exchanger with smooth pipes.
It is a well thought-out principle using sustainable materials.
The boiler burns (natural) gas to supply heat. This heat is transferred in the heat
exchanger to the water in the CH installation. The rapid cooling off of the ue gases
causes condensation. This results in a very high yield. The condensation that is formed,
has no negative impact on the heat exchanger and it's operation, and is removed through
the internal siphon.
The boiler is equipped with an intelligent control system: CMS (Control Management
System). Each boiler anticipates the heat request of the heating installation. This will
cause the boiler to tune its capacity to the installation. This means that the boiler will
function longer and at a low level.
The boiler has been tested according to valid CE* standards and has a CE* certicate
and SEDBUK A-rating.
Statement: No banned materials including asbestos, mercury, CFC's have or will not be
included in the product.

5 Mounting the boiler
The room where the boiler will be placed must always be frost free. The boiler casing is
splash water tight (IPX4D) and is suitable to be installed in e.g. a bathroom.
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 boiler can be mounted practically to any wall with the suspension bracket and the
enclosed xing equipment. The wall must be at and of sufcient strength in order to be
able to carry the boiler weight with its water content.
Above the boiler there must be at least 250 mm working space in order to be able to t a
coaxial ue 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 tting or removing of casing. The location
of the boiler can be determined by using the template.
Before hanging the boiler remove the outer boiler casing. The cover is also the air cabinet
and is attached to the rear wall with four quick fasteners (A, B, C and D) (see gure 1).
Secure the quick fasteners with the screws (A, B, C and D) at the back of the
cover.
Lift the boiler only by the boilers rear wall.
Figure 1
Lifting and carrying precautions:
- Lift only a manageable weight, or ask for help.
- When lifting the boiler, bend the knees, and keep the back straight and feet
apart.
- Do not lift and twist at the same time.
- Lift and carry the boiler close to the body.
- Wear protective clothing and gloves to protect from any sharp edges.

6 Connecting the boiler
The boiler has the following connection pipes;
- The central heating pipes.
These can be connected to the installation by means of compression ttings / adapter
ttings;
- The gas pipe.
It is provided with a female thread into which the tail piece of the gas isolation valve
can be screwed;
- The condensation drain pipe.
It consists of a 22mm plastic pipe. The drain pipe can be connected to this by means
of an open connection. If the open connection is tted in a different location, then the
pipe can be lengthened by means of a 32 mm PVC sleeve;
- The ue gas exhaust system and air supply system.
It consists of a concentric connection 60/100 mm.
Isolation valves are not permitted to be installed on open vent boilers.
It is advisable to spray-clean all of the boiler’s connecting pipes and/or to spray-
clean/blow-clean the installation before connecting it to the boiler.
6.1 Open vent heating system
This boiler is only suitable for installations that have been equipped with “open”
expansion tanks (Open vent).

The boiler pipes have to be connected to the installation by means of compression
ttings. For connecting to thick-walled pipe (welded or tted), adapters should be used.
When removing the plastic sealing caps from the pipes, contaminated testing
water may be released.
If all, or a substantial part of the radiators have thermostatic radiator valves, a pressure
regulator has to be used to prevent ow problems in the installation. The pressure
regulator used should have the same diameter as the connecting diameter of the supply
and return pipe of the boiler. See also chapter 5.1.
An Adey Magnaclean or Fernox TF1 lter is recommened to be installed,
preferably on the return pipework as close to the boiler practitable.
Additives in the installation water are only permitted in consultation with the
country distributor. ATAG Heating UK Ltd recommend the use of either Fernox
or Sentinel products.
6.2 Heating systems with plastic pipes
When connecting or using an underoor 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 underoor heating component will have to
be separated from the central heating appliance 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 underoor heating pipes.
