It is fitted with an automatic domestic hot water priority valve. A Summer/winter switch is fitted to the left hand side of the control panel. With the Summer only switch position being for domestic hot water. The summer/winter position being for central heating with domestic hot water priority. The boiler is equipped with a front cover which can be removed for servicing. The data badge with technical data is placed on the lower part of the left hand side panel. etc ,with heating circuit fully charged so as to operate the low water sensor device the boiler will start in the same way as domestic hot water mode . As the heating sensor reaches temperature the fan speed modulates down. When starting, the fan will always start at the set-point speed. 2.2.8 On the control panel are mounted two potentiometers (thermostats) these control the temperature. One is for domestic hot water and the other for heating. 2.2.9 The boiler is fitted with an anti-cycling device on the control board. This delays the boiler from re-firing over a 10 minute. If the heating temperature goes 20°C below the set point, the burner restarts immediately. The domestic hot water will always take priority and is unaffected by the anti-cycling device. Fig.1 Illustrates the general layout of components. Fig.2 Illustrates the operating principles described in section 2. GENERAL FUNCTION SECTION 2 2.1 DESCRIPTION OF CONTROL SYSTEM AND SEQUENCE OF OPERATION 2.2 Domestic hot water mode When the appliance is in rest mode with the mains neon and switch on. Switch the summer/winter switch to Summer position, with the heating circuit charged with water (above 1 bar). If the domestic hot water tap is turned on, the boiler will function in the following sequence: The pump starts. The fan starts and sends a signal back to the ignition board that the fan is running . 2.2.1 2.2.2 The spark ignition system is powered which in turn commences the spark igniter to operate and light the burner. At this point the ignition board opens the gas valve to light the burner. 2.2.3 When the electrode sensor senses the signal of the burner, the spark igniter stops. 2.2.4 6 From the fan speed setting the boiler increases to the maximum permissible speed over a period of 5 seconds and will remain at its maximum required power until its maximum regulated temperature. 2.2.5 When the domestic hot water tap is closed the diverter valve goes back into rest mode, the burner is shut down along with the fan which is also switched off. 2.2.6 Central heating mode 2.2.7 If the switch is positioned on winter with a demand for heat to supply radiators, 2.3 Central Heating Mode 2.3.1 A potentiometer installed on the panel instruments permits regulation of the boiler to partial heating requirements, between maximum and minimum settings. 2.3.2 Air is drawn by the fan for combustion. 2.3.3 The fan also forces exhaust gas through the flue to the outside, this creates a lesser pressure in the sealed combustion chamber, thus sucking in combustion air, through the inlet duct. 2.3.4 The boiler water temperature is automatically controlled by a built in thermostat 2.3.5 Interior space temperature is set by the room thermostat to be installed in the heating system. The boiler already carries connection terminals for this thermostat, as well as for a timeclock. The burner continues to operate until it is stopped by the timer or one of the thermostats 2.3.6 When the internal C.H. temperature sensor intervenes the burner shuts down. The fan stops but the pump continues to operate. 2.3.7 When the room thermostats intervene the burner shuts down. The fan stops and the pump after 3 minutes turns off. 2.3.8 In summer position an anti-block of the pump is included. Every day the pump is powered for a period of 2 minutes. The boiler also incorporates an anti-block system which powers the pump every 24 hours, allowing it operate for 2 minutes if the boiler has not been in use. This operation may in some cases be heard for a short period when the pump has been activated. 2.4 Domestic hot water mode 2.4.1 The heat exchanger in the D.H.W. circuit is a stainless steel plate heat exchanger water to water, and domestic water is heated by converting the water in the central heating circuit. The transference of heat is very high because the two fluids move in a counter direction flow to each other. 2.4.2 Switch 1a Fig.27 in the winter position. When a hot water tap is turned on a diaphragm diverter valve excludes the central heating circuit, the boiler automatically modulates to maintain the domestic hot water at a constant temperature. 2.4.4 2.4.5 2.5 SAFETY DEVICE In both central heating and domestic hot water mode safe operating is ensured by a control board shuts off the main burner if the fan stops or the flue or combustion air intake duct is obstructed 2.5.1 An overheat cut off thermostat acts to turn of the burner to resetable “lockout” (Fig. 27) . A safety valve is fitted on the central heating circuit set at 3 bar. A low water pressure switch set at 0.4 bar is fitted on heating circuit. Water temperature can be regulated using the D.H.W. thermostat located on the front control panel. 2.4.3 When domestic hot water is being drawn the burner and pump perform as they do during central heating except that the burner is commanded by the D.H.W. thermostat. OVERALL DIMENSION When D.H.W. is no longer called for the boiler automatically returns to the central heating mode. Switch 1a in the Fig.27 in summer position The boiler functions like an automatic gas hot water heater When D.H.W. is no longer required the burner and fan immediately turn off. This also takes place when switch 1a is on Winter if there is no demand for heat to the central heating system or until the room thermostat/time clock demands for central heating circuit. 2.5.2 2.5.3 Fig. 3 AVAILABLE PUMP HEAD Fig.4 PRESSURE DROP ACROSS APPLIANCE Fig.5 7 SECTION 3 TECHNICAL DATA CSI 120 (T) Low Nox TABLE 1 NATURAL GAS (G 20) І2H - П2H3+ NOMINAL HEAT INPUT NET QMS MINIMUM HEAT INPUT NET 26.0 kW 5.78 kW NOMINAL HEAT OUTPUT NOMINAL HEAT OUTPUT CONDENSING MINIMUM HEAT OUTPUT MINIMUM HEAT OUTPUT CONDENSING 25.7 kW 28.8 kW 5.72 kW 6.41 kW GAS RATE AFTER 10 MINUTES max min INLET PRESSURE 20 mbar FAN SPEED C.H.

If in doubt advice must be sought from the local gas supplier The combination boiler may be installed in any room or internal space, although particular attention is drawn to the requirements of the current I.E.E. Wiring Regulations, and in Scotland the electrical provisions of the Building Regulations applicable in Scotland, with respect to the installation of the combination boiler in a room or internal space containing a bath or shower. Where a room sealed appliance is installed in a room containing a bath or shower, any electrical switch or appliance control, utilising mains electricity should be so situated that it cannot be touched by a person using a bath or shower. A compartment used to enclose the combination boiler MUST be designed and constructed specifically for this purpose. An existing cupboard, or compartment, may be used provided it is modified accordingly Samples of the CSI combination boiler have been examined by B.G. Technology Notified Body, and is certified to comply with the essential requirements of the Gas Appliance Directive 90/396/EEC, the Low Voltage Directive 72/23/EEC and shows compliance with the Electro Magnetic Compatibility Directive 89/336/EEC and are therefore permitted to carry the CE Mark. 4.6.1 The terminal should be located where dispersal of combustion products is not impeded and with due regard for the damage or discolouration that might occur to building products in the vicinity (see fig. 6). The terminal must not be located in a place where it is likely to cause a nuisance In cold and/or humid weather water vapour may condense on leaving the flue terminal. The effect of such steaming must be considered. The terminal must not be closer than 25 mm (1 in) to any combustible material For protection of combustibles, refer to BS 5440.1. Where a flue terminal is installed less than 1000 mm. from a plastic, or painted gutter; or 500 mm from painted eaves, an aluminium shield 1000 mm. long, should be fitted to the underside of the gutter or painted surface. The appliance has been tested and approved by the WRc as meeting the requirements of G3 and L of the Building regulations and water Bylaws Scheme - Approved Products. 4.5 GAS SUPPLY 4.5.1 A gas meter is connected to the service pipe by the Local Gas Region or the Local Gas Region contractor. An existing meter should be checked preferably by the Gas Region to ensure that the meter is adequate to deal with the rate of gas supply required for all appliances it serves. Installation pipes should be fitted in accordance with BS 6891. Pipework from the meter to the boiler must be of adequate size (22 mm) min To within at least 3 metre of the boiler (15 mm) min. can then be used for remaining pipe work to the appliance. A smaller size than the boiler inlet gas connection should not be used The complete installation must be tested for soundness as described in the above Code. N.B. if the gas supply for the boiler serves other appliances ensure an adequate supply is available both to the boiler and the other appliances when they are in use at the same time. FLUE SYSTEM Pluming will occur at the terminal so, where possible, terminal positions which could cause a nuisance should be avoided. The flue must be installed in accordance with the recommendations of BS 5440: Part 1. IMPORTANT NOTES For greater flue lengths see alternative flue instructions. Flue must be positioned in a place not likely to cause a nuisance from pluming. IMPORTANT NOTICE: If the flue terminates less a balcony, above the ground, or above a flat roof to which people have access, then a suitable terminal guard must be fitted 0001PRO06005/0. Fit only recommended FLUE TERMINAL GUARD by securing concentrically around terminal with screws.

The following notes are given for general guidance. 4.8.2 Pipework Copper tubing to BS 2871 1.1.1971 is recommended for water pipes. Jointing should be either with capillary soldered or with compression fittings. Where possible pipes should have a gradient to ensure air is carried naturally to air release points and water flows naturally to drain taps. It should be ensured as far as possible that the appliance heat exchanger is not a natural collecting point for air except where providing useful heat, pipes should be insulated to prevent heat loss and to avoid freezing. Particular attention should be paid to pipes passing through ventilated spaces in roofs and under floors. 4.8.3 The water through the appliance heat exchanger circuit must exceed the min. 2.38 gals/min. (650 It/h) when the burner is firing. It is important to ensure that this rate is achieved when sections of the system are shut off either manually or by automatic controls. Therefore a by-pass must be fitted to the system (15 mm min.) (Fig. 6). If the volume of circulating water is too low, the boiler water temperature will rise too rapidly. This could cause noise in the system or even cause the safety thermostat to trip. 1200 1500 300 300 NOTE: The flue must be terminated in a place not likely to cause a nuisance. 4.6.2 A concentric vertical flue kit is available for flueing applications up to a maximum height of 4 metres. For further details see vertical flue installation instructions. 4.7 AIR SUPPLY 4.7.1 The following notes are intended for general guidance. The room sealed fan flued boiler does not require a permanent air vent for combustion air supply. Where installed in a cupboard or compartment ventilation is not required. Fig.6 14 4.8.4 Draining tap These must be located in accessible positions to permit the draining of the whole system. The taps must be at least 15 mm nominal size and manufactured in accordance with BS 2870 1980. 4.8.5 Air release points These must be fitted at all high points where air will naturally collect, and must be sited to facilitate complete filling of the system. 4.8.6 The appliance has an integral sealed expansion vessel to accommodate the increase of water volume when the system is heated. It can accept up to 6 Its of expansion water. If the appliance is connected to a system with an unusually high water content, calculate the total expansion and add additional sealed expansion capacity as appropriate (Fig. 7). In general, modern systems will present no problem. 4.8.8 Fig.7 4.8.7 Mains water feed: central heating There must be no direct connection to the mains water supply, even through a nonreturn valve, without the approval of the Local Water Authority. Permissible methods of filling Fig.8 Figure depicts the requirements of Diagram R24.2a of the Water Supply (Water Fittings) regulations 1999. 15 SIZING OF ADDITIONAL EXPANSION VESSEL: TABLE 3 Deduct from the value given in the table the 7 litre vessel supplied.

An 25mm plastic overflow pipe is fitted on the condensing trap and must should be used to fit on the drain connection, if required, to discharge condensate to a drain. The drain pipe should have a fall of a least 2.5° away from the boiler. Condensate should, if possible be discharged into the household internal drainage system. POSITION OF WATER AND GAS CONNECTIONS Fig. 26 INSTRUMENT PANEL Fig. 27 26 If this is not practicable, discharge can be allowed into the external household drains or a purpose designed soak away. It is recommended that any external condensate drain pipe is insulated and also preferably of 32 mm diameter, to prevent freelzing in adverse weather conditions. The condensate is discharged periodically in “ slugs” by siphonic action. It is not necessary to provide air breaks or extra traps in discharge pipe as there is already a 125mm high trap inside the boiler. Fitting an extra trap may cause the boiler siphon to work incorrectly. Refer to BS5546 or BS6798 for advice on disposal of boiler condensate. SECTION 6 COMMISSIONING 6.1 Each boiler has been through a rigorous operational procedure at our factory and should not require any further adjustment If in the unlikely event of the appliance not operating correctly, please turn to the Fault Finding and Logic Sequence charts. 6.2 GAS SUPPLY INSTALLATION 6.2.1 Inspect the entire installation including the gas meter, test for soundness and purge, all as described in BS 6891. 6.3 ELECTRICAL INSTALLATION Preliminary electrical systems checks to ensure electrical safety shall be carried out by a competent person (earth continuity, polarity, resistance to earth). Those checks are outlined in the «Instructions for British Gas Multimeter» Booklet. If a fault has occurred on the appliance the fault finding procedure should be followed as specified under the servicing section of this document. 6.4 INITIAL FILLING OF THE SYSTEM Open central heating flow and return valves Unscrew the cap on automatic air release valve positioned on the top of the pump housing one full turn (leave open permanently). - Close all air release taps on the central heating system. - Gradually open stopcock at the filling point connection to the central heating system until water is heard to flow. - Starting with the lowest radiator open each air release tap in turn. Close it only when clear water, free of bubbles, flows out. In the same way release air from any high points in the pipework. GAS VALVE - Continue filling the system until 1.5 bar register on gauge. Then turn off the filling points stopcock. - Inspect the system for water soundness and remedy any leaks discovered 6.5 SETTING THE SYSTEM DESIGN PRESSURE The design pressure must be a min. 1 bar and max. 1.5 bar. These figures are read off the pressure gauge. - The actual reading should ideally be 1 bar + the height in metres to the highest point of the system above the base of the appliance (up to max of 1,5 bar). N.B.: They safety valve is seat to lift a 3 bars (30 mt/42.5 psing). - To lower the system pressure to the required value remove drain point (Fig. 29) or drain on the heating circuit. 6.6 FILLING THE HOT WATER SYSTEM Close all hot water draw-off taps. Open the cold water inlet cock. Slowly open each draw-off tap until clear water is discharged. 6.7 LIGHTING THE BOILER Before lighting the boiler make sure that the heating circuit flow and return valves are open and also that the cold water input cock is open. - If external controls are installed (e.g timeclock and thermostat) make sure that they call for heat. - Push Summer/Winter switch (1A) Fig.27 to Winter . IMPORTANT: Before switching on the boiler POWER SWITCH FOR THE FIRST TIME when commissioning, turn the heating control knob (Fig.27) DOWN TO ITS MINIMUM setting leaving it at minimum for approx 5 mins to purge air saffely from the boiler heat exchanger. Fig. 28 Fig. 29 27 -Turn control knob 4 (Fig.27) down to its minimum setting. -Push the power main switch to on (Fig.27) -The digital display will show water set point temperature in central heating . -The fan start and after a few second the digital led display will show that the ignition commence. -NOTES : It maybe necessary to reset the Digital Timer on boiler (if fitted) to start. Put the timer to on position (Fig.27) -The ignition control will automatically have three attempts , but initially this may be due to air in the gas supply line.If the burner fails to light, the digital led display and fan will stop, and the display will show the lockout code. -If necessary push the boiler Reset button (Fig.27) and the boiler will restart automatically. -After the boiler has light , allow to warm at minimum temperature setting to purge any air from the system. -Once the system has been purged of air turn the control knob (Fig.27 item 4) to the desired position. With leak detection fluid test for gas soundness of all gas components and joints.See paragraph 6.14 for regulating the heating circuit control knob. 6.8 CHECK THE GAS PRESSURE Check the gas mains pressure at at the gas valve test nipple UPSTREAM ( Fig.28 ) with boiler operating Check with the Local Gas supplier if the pressure differ significabntly from 20 mbar G20 (natural gas), 37 mbar G31 (propane) and 29 mbar G30 (butane) IMPORTANT : Any adjustement to the gas valve should only be carried out by a qualified person Refer to table 6.10 adjust the maximum level of CO2 by turning the Throttle on the gas valve ( Fig.28 ). Anti-clockwise to increase CO2 Clockwise to decrease CO2 After any new regulation wait to stabilise about one minute. - Replace the sample point screw on the flue manifold ( Fig.1 item 8) - Replace the front panel of the case. RATIO BETWEEN FAN SPEED AND HEAT INPUT Fig. 30 ELECTRODES POSITION Fig. 31 IMPORTANT :The Gas Valve Throttle adjuster is required to be sealed with tamper proof paint after adiustment. 6.9 28 COMBUSTION CHECK : If a gas carrying components has been replaced, the combustion of the appliance should be checked as follows. Remove the front panel of the case. Ensure the boiler and external controls are calling for heat. Turn on electrical supply. Open the Hot water tap at maximum flow rate. Wait at least five minutes or until the unit has reached its operating temperature. Unscrew the test sample screw on the boiler elbow band (Fig.10 ). Measured the level of CO2. Check the reading against the corresponding value in sect.3 TECHNICAL DATA If adjustment proves necessary then proceed as follows. Once the process of commissioning the boiler is complete, the commissioning engineer MUST complete his section in the Benchmark log book. 6.10 CHECKING THE FLUE SYSTEM 6.10.1 The flue system should be visually checked for soundness Check all connections and fixings are secure and tight 6.11 CHECKING THE HEATING THERMISTOR 6.11.1 Allow the system to warm up and then turn the C.H thermistor to ensure the main burner modulates from “high” to “low” and “low” to “off” and vice versa (scale range covers approx. 45° C / 85° C). 6.12 TESTING AND REGULATING THE DOMESTIC HOT WATER SYSTEM FLOW 6.12.1 Put the appliance in summer position with the (summer/winter) switch (Fig.27). - Open a domestic hot water tap (preferably the bath tap). Ensure cold water inlet stopcock is open and the D.H.W. control knob (Fig.27) is set at maximum. - Digital display show water temperature in demand ( led on) - If the boiler does not light check that the water flow rate is above the min. required to operate the differential pressure 2 8 Lts./ min. (0.61 gals/min). - The temperature of the water will depend on the rate at which it flows. If, due to high water pressure, the flow rate is too high (and thus the temperature too low for practical use) the flow rate may be adjusted. It is better to set for the lowest acceptable temperature, preferably at the bath tap since the user can gain higher temperatures at other restricted flow taps (Table ...) -If the cold supply is subject to large fluctuations or is above the permitted max. water pressure, a suitable pressure/flow regulator should be fitted in the cold water supply to the appliance. - Slowly close the draw off tap to reduce the flow rate to above the min (approx. 2.8 litre/min) - 0.61 gals/min.). Rotate the D.H.W. control knob to ensure it operates at its various setting. - Close the draw-off tap still further. The burner should stop when the rate falls below about 2.8 litres/min (0.61 gals/min ). 6.13 HANDING OVER TO THE USER 6.13.1 After completion of installation and commissioning of the system, the installer should hand over to the Householder by taking the following actions: - Hand the “User’s Instructions” to the Householder and explain His/Her responsibilities under the “Gas Safety Regulations 2000”. - Explain and demonstrate the lighting and shutting down procedures. - The operation of the boiler including the use and adjustment of ALL system controls which should be fully explained to the Householder. This then ensures the greatest possible fuel economy consistent with household requirements of both heating and hot water consumptions. Advise the User of the precautions necessary to prevent damage to the system, and to the building, in the event of the system remaining inoperative during frost conditions - Explain the function and the use of the boiler switch Summer/Winter and ON/OFF switch,reset and digit display . - Explain and demonstrate the function of temperature controls, neon lights radiator valves etc for the economic use of the system. - If an optional time clock is fitted, then draw attention to the time clock User’s Instructions and hand them to the Householder - Stress importance of regular servicing by a qualified Heating Engineer and that a comprehensive service should be carried out AT LEAST ONCE A YEAR - Fill in the Benchmark log book and leave completed with the customer.
