1.2 Recommendations
Caution
Ensure that the boiler is regularly serviced.
Contact a qualified installer or arrange a
maintenance contract for the servicing of the
boiler.
Caution
Only genuine spare parts may be used.
Important
Regularly check for the presence of water and
pressure in the heating installation.
Danger
This appliance can be used by children aged
eight and above and people with a physical,
sensory or mental disability, or with a lack of
experience and knowledge, provided they are
supervised and instructed in how to use the
appliance in a safe manner and understand the
associated dangers. Children must not be
allowed to play with the appliance. Cleaning and
user maintenance should not be carried out by
children without adult supervision.
Warning
Installation and maintenance of the boiler must be
carried out by a qualified installer in accordance
with local and national regulations.
Warning
The installation and maintenance of the boiler
must be undertaken by a qualified installer in
accordance with the information in the supplied
manual, doing otherwise may result in dangerous
situations and/or bodily injury.
Warning
Removal and disposal of the boiler must be
carried out by a qualified installer in accordance
with local and national regulations.
Warning
If the mains lead is damaged, it must be replaced
by the original manufacturer, the manufacturer's
dealer or another suitably skilled person to
prevent hazardous situations from arising.
1 Safety
7725131 - v.01 - 06062019 AMC Pro 9
Warning
Always disconnect the mains supply and close
the main gas tap when working on the boiler.
Warning
Check the entire system for leaks after
maintenance and servicing work.
Danger
For safety reasons, we recommend fitting smoke
and CO alarms at suitable places in your home.
Caution
Make sure the boiler can be reached at all
times.
The boiler must be installed in a frost-free area.
If the power cord is permanently connected, you
must always install a main bipolar switch with
an opening gap of at least 3 mm (EN 60335-1).
Drain the boiler and central heating system if
you are not going to use your home for a long
time and there is a chance of frost.
The frost protection does not work if the boiler is
out of operation.
The boiler protection only protects the boiler,
not the system.
Check the water pressure in the system
regularly. If the water pressure is lower than 0.8
bar, the system must be topped up
(recommended water pressure between 1.5 and
2 bar).
Important
Keep this document near to the boiler.
Important
Only remove the casing for maintenance and
repair operations. Refit all panels when
maintenance work and servicing are complete.
Important
Instruction and warning labels must never be
removed or covered and must be clearly legible
throughout the entire service life of the boiler.
Damaged or illegible instructions and warning
stickers must be replaced immediately.
Important
Modifications to the boiler require the written
approval of De Dietrich.

Warning
Fix the appliance to a solid wall capable of bearing the weight of
the boiler when full of water and fully equipped.
Do not place the appliance above a heat source or a cooking
appliance.
Do not locate the boiler in direct or indirect sunlight.
Caution

4 Preparation of installation
16 AMC Pro 7725131 - v.01 - 06062019
4.3 Requirements for CH water connections
When fitting service shut-off valves, position the filling and drain valve,
the expansion vessel and the safety valve between the shut-off valve
and the boiler.
Carry out any welding work required at a safe distance from the boiler or
before the boiler is fitted.
For filling and tapping the boiler, install a filling and drain valve in the
system, preferably in the return.
Install an expansion vessel in the return pipe.
4.4 Requirements for condensate drain line
The siphon must always be filled with water. This prevents flue gases
from entering the room.
Never seal the condensate drain.
The drain pipe must slope down at least 30 mm per metre, the maximum
horizontal length is 5 metres.
Condensed water must not be discharged into a gutter.
4.5
4.6
Requirements for gas connection
Before starting work on the gas pipes, turn off the main gas tap.
Before installing, check that the gas meter has sufficient capacity. Take
into account the consumption of all appliances.
Notify the local energy company if the gas meter has insufficient
capacity.
Remove dirt and dust from the gas pipe.
Always perform welding work at a sufficient distance from the boiler.
We recommend installing a gas filter to prevent clogging of the gas
valve unit.
Pipe diameters must be defined in accordance with ATG's (Association
Technique de Gaz) B171 specifications.
Requirements for the electrical connections
Establish the electrical connections in accordance with all local and
national current regulations and standards.
Electrical connections must always be made with the power supply
disconnected and only by qualified installers.
The boiler is completely pre-wired. Never change the internal
connections of the control panel.
Always connect the boiler to a well-earthed installation.
The standard NF C 15,100.
The standard CEI.
The wiring must comply with the instructions in the electrical diagrams.
Follow the recommendations in this manual.
Separate the sensor cables from the 230 V cables
Outside the boiler: Use 2 cables spaced at least 10 cm apart.

The maximum length of the flue gas outlet and air supply channel vary
depending on the appliance type; consult the relevant chapter for the
correct lengths.
Important
When using bends, the maximum chimney length (L) must be
shortened according to the reduction table.

Connecting the flue gas outlet
Connecting the air supply
With a room-ventilated version, the air supply opening stays open; only the
flue gas outlet opening is connected. This will ensure that the boiler
obtains the necessary combustion air directly from the installation area.
Caution
The air supply opening must stay open.
The installation area must be equipped with the necessary air
supply openings. These openings must not be obstructed or
shut off.

4.7.5 Additional guidelines
Installation
For installing the flue gas outlet and air supply materials, refer to the
instructions of the manufacturer of the relevant material. After
installation, check at least all flue gas outlet and air supply parts for
tightness.
Warning
If the flue gas outlet and air supply materials are not installed in
accordance with the instructions (e.g. not leak-proof, not correctly
bracketed), this can result in dangerous situations and/or physical
injury.
Make sure that the flue gas outlet pipe towards the boiler has a sufficient
gradient (at least 50 mm per metre) and that there is a sufficient
condensate collector and discharge (at least 1 m before the outlet of the
boiler). The bends used must be larger than 90° to guarantee the
gradient and a good seal on the lip rings.
4 Preparation of installation
24 AMC Pro 7725131 - v.01 - 06062019
Condensation
Direct connection of the flue gas outlet to structural ducts is not
permitted because of condensation.
If condensate from a plastic or stainless steel pipe section can flow back
to an aluminium part in the flue gas outlet, this condensate must be
discharged via a collector before it reaches the aluminium.
Newly installed aluminium flue gas pipes with longer lengths can
produce relatively larger quantities of corrosion products. Check and
clean the siphon more often in this case.
Important

4.8
Water quality and water treatment
4.9 Process heat application
The quality of the CH water must comply with certain limit values, which
can be found in our Water quality instructions. The guidelines in these
instructions must be followed at all times.
In many cases, the boiler and central heating system can be filled with
normal tap water and water treatment will not be necessary.
In process heat applications (for example pasteurisation and drying and
washing processes), the boiler is being used for industrial purposes and
not for central heating. With process heat, the nominal flow (at ΔT 20°C) in
the primary CH circuit must be guaranteed. The flow in the secondary
circuit may vary.
To ensure that this is the case, a flow rate sensor can be fitted, which
locks out the boiler if the flow falls below a specified level (due to a
defective pump or valve, for example).
Important
The service life of the boiler may be reduced if it is used for
process heat applications.
For more information, see
Setting for process heat application, page 60
4.10 Increase default ΔT setting
In some cases, the default ΔT setting of the boiler will need to be
increased, for example in systems with:
underfloor heating
air heating
district heating
a heat pump.
Important
Prevent the boiler from locking out and ensure a minimal water
circulation by using a bypass or low-loss header.
For more information, see
Changing the default ΔT setting, page 61
