Water flow

Manometric height central heating circuit

The boiler is fitted with a modulating pump which is regulated by the control panel as a function of ΔT= (Flow T °C - Return T °C).

The graph shows the manometric height at various outputs. The parameters MIN.PUMP SPEED and MAX.PUMP SPEED are used to modify the pump settings. If flow noise can be heard in the system, it is possible to reduce the maximum pump speed with the parameter MAX.PUMP SPEED (First of all, vent the heating system). If circulation in the radiators is too low or the radiators do not fully heat up, increase the minimum pump speed with the parameter MIN.PUMP SPEED.

¼See chapter: "Professional settings", page 114.

4.2.3. Water flow rate

The boiler’s modulating control system limits the maximum difference in temperature between the heating flow and return and the maximum speed at which the flow temperature increases. In this way, the boiler does not require a minimum water flow rate.

5.2.3. Ventilation

CAUTION

In order to avoid damage to the boiler, it is necessary to prevent the contamination of combustion air by chlorine and/or fluoride compounds, which are particularly corrosive. These compounds are present, for example, in aerosol sprays, paints, solvents, cleaning products, washing products, detergents, glues, snow clearing salts, etc. Therefore:

4 Do not pull in air evacuated from premises using such

products: hairdressing salons, dry cleaners, industrial premises (solvents), premises containing refrigeration systems (risk of refrigerant leakage), etc.

4 Do not stock such products close to the boilers.

If the boiler and/or peripheral equipment are corroded by such chloride or fluoride compounds, the contractual guarantee cannot be applied.

Type C - Forced flue version

If the evacuation of combusted gases and the intake of combustive air are done using a concentric conduit, ventilation of the boiler room is not necessary.

Condensing boilers require a flue gas discharge system or a fresh air inlet specially adapted to the method of operation. Installation must be carried out in accordance with current laws.

CAUTION

Do not block the air inlet, combustion product evacuation or condensation water flow pipes (even partially).

Avoid any low points in the flue gas and condensates discharge circuit in order to prevent any condensates accumulation.

Type B - Open flue

Condensing boilers require a flue gas discharge system or a fresh air inlet specially adapted to the method of operation. Installation must be carried out in accordance with current laws.

Position the air inlets in relation to the high ventilation vents in order that the air is refreshed throughout the boiler room.

CAUTION

4 Avoid any low points in the flue gas and condensates

discharge circuit in order to prevent any condensates accumulation.

4 Do not block the air inlets in the room or the

combustion products evacuation or condensation water flow pipes (even partially).

pH > 6,5

AFC 18 - AFC 24 - AFC 30 5. Installation

The installation must be constructed in accordance with prevailing technical regulations. Depending on prevailing regulations, it is possible to use a neutralisation station to bring the pH down to a value of more than 6,5.

1. Mount a standard drainage pipe, DN 32 or more, leading to the mains drainage system.

2. Connect the condensates discharge pipe with a gradient sufficient to ensure flow through the siphon to the wastewater network.

3. Mount a trap or a siphon in the discharge pipe.

CAUTION

Do not make a permanent rigid connection owing to maintenance work on the condensate trap.

4 The condensate drain must be connected openly to

the drain.

4 Set the discharge pipe at a gradient of at least 30 mm

per metre, maximum horizontal length 5 metres.

4 Do not drain condensation water into a roof gutter at

any time.

4 Connect the condensate discharge pipe in

accordance with prevailing standards.

CAUTION

If operating with the siphon empty, combustion products will escape into the premises in which the boiler is installed.

1. Pour water into the flue gas conduit (central pipe) until it flows out of the condensates discharge pipe 2.

5.5 Oil connection

5.5.1. General

4 Use a single-pipe system and mount the oil filter with the deaerator

and the stop valve (provided with the boiler). The negative pressure required for the oil supply must be less than 0.35 bar (0.035 MPa).

4 Use of a floating strainer is strongly recommended to prevent

deposits being sucked up from the bottom of the tank.

4 If replacing the boiler, clean the tank.

5.6 Flue gas system connections - Depending on country

CAUTION

To obviate any transmission of boiler operating noise into the home, the flue gas connection pipes must not be bricked into the walls. Use a sleeve.

WARNING

Fix the concentric conduits to the wall using clamps and brackets. The conduits come under stress at each startup and may eventually work free of their fitments. Should this happen, the boiler continues to operate and pollutes the air in the premises. This risk is even higher when the length of the flue gas connection pipe to the wall or chimney is significant. The horizontal flue gas pipes must be installed with a minimum gradient of 1% to allow the flow of the condensates that form in the pipes to the boiler siphon.

5.6.1. Connections for the air and exhaust pipes -

5.10.1. Water treatment

In most cases, the boiler and the central heating installation can be filled with normal tap water and no water treatment will be necessary.

WARNING

Do not add chemical products to the central heating water without first consulting a water treatment professional. For example: antifreeze, water softeners, products to increase or reduce the pH value, chemical additives and/or inhibitors. These may cause faults in the boiler and damage the heat exchanger.

For an optimum functioning of the boiler, the water of the installation must comply with following characteristics:

Degree of acidity (water non-treated) pH 6,5 - 8,5 Degree of acidity (water treated) pH 7 - 9 Conductivity at 25°C µS/cm ≤ 500 Chlorides mg/l ≤ 50 Other components mg/l < 1 Total water hardness °f 5- 35

°dH 2,8 - 20,0 mmol/l

(1) Flow temperature lower than 90°C - Maximum hardness: 1,50 mmol/l

Total installed heat output (kW)

≤ 70

(1)

0,5 - 3,5

4 Flush the central heating installation with at least 3x

the volume of the central heating installation. Flush the DHW pipes with at least 20 times the volume of the pipes.

If a water treatment is necessary, De Dietrich Thermique recommends the following manufacturers:
