(doorbell, lighting, motor, lift etc).

2. Shut off the gas supply.

3. Open the windows.

4. Trace possible leaks and seal them off
immediately.

5. If the leak is upstream of the gas meter, notify
the gas company.

Danger
If you smell flue gases:

1. Switch the boiler off.

2. Open the windows.

3. Trace possible leaks and seal them off
immediately.

Caution
After maintenance or repair work, check the
entire heating installation to ensure that there are
no leaks.

For the end user:

the boiler settings, the temperature of the flue gas
pipes can rise to over 60°C.

Warning
Do not touch radiators for long periods.
Depending on the boiler settings, the temperature
of the radiators can rise to over 60°C.

Warning
Be careful when using the domestic hot water.
Depending on the boiler settings, the temperature
of domestic hot water can rise to over 65°C.

Warning
The use of the boiler and the installation by you
as the end-user must be limited to the operations
described in this manual. All other actions may
only be undertaken by a qualified fitter/engineer.

Warning
The condensation drain must not be changed or
sealed. If a condensate neutralisation system is
used, the system must be cleaned regularly in
accordance with the instructions provided by the
manufacturer.

Caution
Ensure that the boiler is regularly serviced.
Contact a qualified installer or arrange a
maintenance contract for the servicing of the
boiler.

1.2 Recommendations

7600532 - v.11 - 13122018 7

1 Safety

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.

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.

1 Safety

8 7600532 - v.11 - 13122018

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).

1.3

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.

4.1 General description

4 Description of the product

The C 330 ECO / C 630 ECO is a freestanding gas boiler with the
following characteristics:

High-efficiency heating.
Heat exchanger made of cast aluminium sections.
Limited emissions of polluted substances.
Has transport wheels as standard.
Left- or right-hand version of the water and flue gas side connections
possible.
Separable for assembly in boiler room.
DIEMATIC iSystem or IniControl control panel.
The C 630 ECO comprises a left-hand and a right-hand module. These
are combined on the flue gas side (optionally on the air side) and also in
terms of their casing.

The following boiler types are available:

4.2.1 Regulating the water temperature

The boiler is fitted with an electronic temperature control with a flow and
return temperature sensor. The flow temperature can be adjusted between
20°C and 90°C. The boiler modulates back when the set flow temperature
is reached. The switch-off temperature is the set flow temperature + 5°C.

4.2.2 Protection against shortage of water

The boiler is fitted with protection against a shortage of water that is based
on temperature differences (difference in temperature between flow and
return). From ΔT = 25K (factory setting) the boiler reduces its output by
modulating to remain in operation as long as possible. At ΔT ≥ 25K, the
boiler goes into part load. At ΔT > 25 + 5K, the boiler goes into a normal
control stop (blocking).

4.2.3 Maximum protection

The maximum temperature protection shuts the boiler down in the event
that an excessively high water temperature (110 °C) is reached. Once the
cause of the fault has been remedied, the boiler can be unlocked by

pressing the button for 2 seconds.

4.2.4 Air pressure differential switch

Before a start and when the boiler is in operation, the air pressure
differential switch PS measures the difference in pressure between the

measuring points on the back of the heat exchanger p+ and the air box p-.

4 Description of the product

20 7600532 - v.11 - 13122018

If the pressure difference is greater than 6 mbar, then the boiler will lock
out. Once the cause of the fault has been remedied, the boiler can be

unlocked by pressing the button for 2 seconds.

4.2.5 Circulating pump

The boiler does not have a built-in pump. A circulating pump can be
installed on the connector of the standard control PCB. This can be an
on/off pump or a modulating pump (with 0 - 10 V control).

The pump settings can be changed.

See
Manual for the control panel.

Warning
The boiler must be installed by a qualified installer in accordance
with local and national regulations.

Choice of the location

Position of data plate

5.2.1 Data plate

The identification plate is located behind the boiler casing on the frame,
near the syphon connection. The data plate provides important information
on the boiler specifications such as the model and the device category.

5.2.2

Use the guidelines and the required installation space as a basis for
determining the correct place to install the boiler.
When determining the correct installation area, take account of the
permitted position of the flue gas outlet and/or air supply outlet.
Ensure that there is sufficient space around the boiler for good access
and ease of maintenance.
A technical clearance of at least 80 cm is required at the front (service
side) of the boiler. However, we recommend that the clearance is at
least 100 cm. Above the boiler, we recommend a clearance of at least
40 cm (when using an air inlet filter, the clearance must be at least 65
cm). A minimum of 30 cm is required on the side of the flue gas outlet,
and a minimum of 30 cm is also required on the other side (or 80 cm, if
this is operating side).

Inspection trap (service side)

The service side with the inspection trap on the heat exchanger is
considered to be the front of the boiler. The boiler is available in both a
'left-hand' and 'right-hand' version. This means that the hydraulic
connections and the flue gas discharge are situated on either the left or
the right-hand side of the boiler. The control panel is on the front as
standard, but can easily be rotated so that it is on the short side.

The adjustment bolts must be used to make the boiler level and to raise
the wheels off the floor. Turn the adjustment bolts outwards as soon as the
boiler is placed in the correct position. The figure shows the support
surface of the boiler (this is the position of the adjustment bolts).
