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:

558 kW output 700 kW output 850 kW output 994 kW output 1148 kW output 1303 kW output

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-.

Page 20

AD-0000521-01

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.

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).

Left-hand version

Right-hand version

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).

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.

Page 36

6 Installation

36 7600532 - v.11 - 13122018

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.

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.

Important Contact us for more information.

6.4.5 Connecting the flue gas outlet

The boiler is equipped with a mechanical flue gas non-return valve as standard. This prevents flue gases from flowing back into the boiler when it is not in operation (cascade settings for example).

Proceed as follows to connect the flue gas outlet:

1. Fit the flue gas outlet pipe to the boiler.

2. Fit the subsequent flue gas outlet pipes in accordance with the manufacturer's instructions.

Caution

The pipes must be flue gas-tight and corrosion-resistant. The materials used must comply with the prevailing regulations and standards. The flue gas outlet pipe must be smooth and deburred. Connect the pipes so that they are stress-free. The pipes must not rest on the boiler or flue gas adapter. Fit the horizontal parts sloping down towards the boiler, with a slope of 50 mm per metre. Maximum bracket spacing for vertical pipes is 2 m. Maximum tilt of vertical pipes is 20 mm per meter. Use a bracket at each connection for horizontal pipes.

6.4.6 Air supply connection

1. Fit the air supply pipe to the boiler.

2. Fit the subsequent air supply pipes in accordance with the manufacturer's instructions.

5. DIEMATIC iSystem: If the water pressure is below 0.8 bar, the symbol will flash (only if a hydraulic pressure sensor is connected). If the water pressure is too low, top up the central heating system.

DIEMATIC iSystem: Do not disconnect the boiler from the power supply. If the central heating system is not used for a long period, we recommend activating the HOLIDAYS mode.

See Manual for the control panel.

IniControl: If the central heating is not due to be used for a long period of time, it is recommended that the boiler be disconnected from the power supply.

1. Turn the on/off switch to the off position.

2. Switch off the boiler's electrical connection.

3. Shut off the gas supply.

4. Keep the area frost-free.

Caution In the event of low temperatures, we recommend that the installation continues to operate at a lower temperature. This will prevent freezing.

8.4

Frost protection

IniControl: Set the temperature control low, for example to 10 °C.

IniControl: If there is no heat demand, the boiler will only switch on to protect itself against frost.

If the temperature of the central heating water in the boiler drops too low, the built-in boiler protection system is activated. This system works as follows:

If the water temperature is lower than 7 °C, the heating pump switches on. If the water temperature is lower than 4 °C, the boiler switches on.

Page 56

8 Operation

56 7600532 - v.11 - 13122018

If the water temperature is higher than 10℃, the boiler shuts down and the circulation pump continues to run for a short time.

To prevent the system and radiators freezing in frost-sensitive areas (e.g. a garage), a frost thermostat or outside sensor can be connected to the boiler.

Caution

The frost protection does not work if the boiler is out of operation. IniControl: The boiler protection only protects the boiler, not the system. DIEMATIC iSystem: The boiler protection only protects the boiler, not the system. To protect the installation, set the appliance to HOLIDAYS mode.

DIEMATIC iSystem: The HOLIDAYS mode protects:

The installation if the outside temperature drops below 3 °C (default setting). The room temperature if a remote control is connected and the room temperature is lower than 6 °C (default setting). The domestic hot water boiler if the boiler temperature is lower than 4 °C (the water is heated to 10 °C).

10 Maintenance

58 7600532 - v.11 - 13122018

10 Maintenance

10.1 General

The cast aluminium/silicon heat exchanger forms the heart of the boiler. When combined with the special geometric shape, the flue gas pollution remains limited. Nevertheless, we recommend cleaning the flue gas side of the heat exchanger thoroughly during the annual inspection and service.

Boilers must be inspected at least once a year or every 3000 operating hours.

Caution

Maintenance operations must be completed by a qualified installer. During inspection or maintenance work, always replace all gaskets of the disassembled parts. Replace defective or worn parts with original spare parts.

Important Adjust the frequency of inspection and service to the conditions of use. This applies especially to boilers in constant use (for specific processes).

Important For work on the C 630 ECO boiler: The features and instructions described apply to each boiler module.

10.2 Standard inspection and maintenance operations

Warning Always wear safety goggles and a dust mask during cleaning work (involving compressed air).

For a service, always perform the following standard inspection and maintenance operations.

Caution

Check whether all gaskets have been positioned properly (absolutely flat in the appropriate groove means they are gas tight). During the inspection and maintenance operations, water (drops, splashes) must never come into contact with the electrical parts.

10.2.1 Preparation

Preparation prior to commencing inspection and maintenance activities:

1. First heat the boiler on high for about 5 minutes (return temperature 65ºC) to dry the heat exchanger on the flue gas side.

10.2.2 Checking the water pressure

1. IniControl: Check the water pressure that is shown on the display (only if a hydraulic pressure sensor is connected).

2. DIEMATIC iSystem: If the water pressure is below 0.8 bar, the symbol will flash (only if a hydraulic pressure sensor is connected).

3. If necessary, top up the central heating system.
