Operation

21 Domestic Hot Water Mode In order to supply hot water, the main switch 19 Fig. 6 must be in ON position I This will be confirmed by the green indicator light 23 Fig. 6. Turn the selector switch 20 clock wise to establish the green DHW indicator 28 Fig. 6. When a tap or shower is turned on, the flow of mains water, above 2 litres per min., will activate the 3 way valve f Fig. 7 to move to the DHW position. The pump will now circulate primary water heated by the main heat exchanger through the secondary heat exchanger. The first stage solenoid a Fig. 7 and safety solenoid c Fig. 7 open together to allow gas to the burner. The ignition sequence begins and a continuous high speed spark ignites the gas. As soon as a flame is detected the orange indicator bulb 24 Fig. 6 will light and the second

Fig. 6

stage solenoid b Fig. 7 opens to allow the full gas rate. If a flame is not detected, after 8 seconds, the security solenoid closes and shuts off the gas. The red lockout indicator bulb 25 Fig. 6 will show. The domestic hot water temperature is controlled by the hot water control thermistor d Fig. 7 and the central heating control thermistor e Fig. 7. This system anticipates the changes of temperature in the secondary heat exchanger and ensures accurate temperature regulation. When the tap is closed the burner is extinguished and the pump stops. Priority will be given to a demand for hot water. This will interrupt the central heating for the duration of hot water delivery.

Central Heating Mode To be able to supply heating, the main switch 19 Fig. 6 must be in I position. This will be confirmed by the green indicator light 23 Fig. 6. Turn the selector switch 21 clock wise to establish the green heating indicator 29 Fig. 6. When there is a demand for heating (either from the room thermostat or the clock) and the boiler temperature control is calling for heat. The pump starts allowing the ignition sequence to begin. The first stage solenoid a Fig. 7 and safety solenoid c Fig. 7 open together to allow gas to the burner. The ignition sequence begins and a continuous high speed spark ignites the gas. As soon as a flame is detected the orange indicator bulb 24 Fig. 6 will light. After 45 seconds the second stage solenoid b Fig. 7 opens to allow the full gas rate. If a flame is not detected, after 8 seconds, the security solenoid closes and shuts off the gas. The red lockout indicator bulb 25 Fig. 6 will show.
The central heating flow temperature is controlled by the central heating control thermistor e Fig. 7. The boiler has been designed to minimise cycling and will not attempt to relight for at least 3 minutes after the boiler thermostat has been satisfied (it is possible to reduce the time to 30 s if necessary). When the room thermostat is satisfied the burner will switch off and the pump will remain running for a further 4 minutes before it to stops. NB : It is possible to override the 3 minute delay by pressing the RESET button 26 Fig. 6.

Installation Requirements
It may be necessary to protect the terminal with a guard. Reference should be made to the Building Regulations for guidance. Suitable guards may be obtained from the following manufacturer: Quinnel Barret & Quinnel Wireworks Old Kent Road London SE15 1NL Tel: 1357 Ventilation The room in which the boiler is installed does not require specific ventilation. If it is installed in a cupboard or compartment permanent ventilation is not required for cooling purposes. Gas Supply The gas installation and soundness testing must be in accordance with the requirements of BS 6891.The boiler requires a 22 mm supply. Ensure that the pipe size is adequate for demand including other gas appliances on the same supply. Electrical Supply The appliance requires an earthed 230V - 50 Hz supply and must be in accordance with current I.E.E. It must also be possible to be able to completely isolate the appliance electrically. Connection should be via a 3 amp fused double-pole isolating switch with contact separation of at least 3 mm on both poles. Alternatively, a fused 3 Amp. 3 pin plug and unswitched socket may be used, provided it is not used in a room containing a bath or shower. It should only supply the appliance.

Location The boiler can be installed on any suitable internal wall. Provision must be made to allow the correct routing of the flue and siting of the terminal to allow the safe and efficient removal of the flue products. A compartment or cupboard may be used provided that it has been purpose-built or modified for the purpose. It is not necessary to provide permanent ventilation for cooling purposes. Detailed recommendations are given in BS 5440 pt 2. If it is proposed that it is installed in a timber framed building then reference must be made to British Gas Document DM2, or advice sought from CORGI. Flue Detailed information on flue assembly is contained in the appropriate starter pack. The boiler must be installed so that the flue terminal is exposed to the free passage of external air at all times. It must not be allowed to discharge into another room or space such as an outhouse or closed lean-to. The minimum acceptable clearances are shown below: - A Directly below an opening, window, etc - B Above an opening, window, etc - C Horizontally to an opening, window, etc - D Below gutters, soils pipes or drain pipes - E Below eaves - F Below balconies or car port roof - G From a vertical drain pipe or soil pipe - H From an internal or external corner - I Above ground roof or balcony level - J From a surface facing the terminal - K From a terminal facing the terminal - L From an opening in the car port into the dwelling - M Vertically from a terminal on the same wall - N Horizontally from a terminal on the same wall - Q Fixed by Ubbink Rolux 4 GM flue terminal 300 mm 300 mm 300 mm 75 mm 200 mm 200 mm 150 mm 300 mm 300 mm 600 mm 1200 mm 1200 mm 1500 mm 300 mm

Installation

Installing the Boiler

Method of positioning the boiler on the wall. The paper template can be used to ensure the correct positioning of kitchen cabinets etc. The paper template has to be fixed to the wall and used to locate the position of the hanging bracket, the centre for the flue hole and, if required, the fixings for the pre-piping jig. Drill and plug the wall and secure the hanging bracket using the screws provided. Remove the boiler from its packaging as shown in fig. 9 and remove the outer case as shown in fig.10.

Please check that you are familiar with the installation requirements before commencing work.(section 6) The installation kit includes the flue components and the flue installation instructions with the boiler you have the following items : - Hanging bracket - A paper template (showing the dimensions of the boiler with 5 mm side clearances and fitting instructions) - Connection tails - Screws and wall plugs - Connection washers and filters
Installing the Boiler (continued)

A Fig. 9 A

Fig. 10
Place the boiler on the wall on the hanging bracket. If required, there is space for all piping to pass behind the boiler. Using fig. 11 for reference, connect the gas and water pipes and the valves to the base of the appliance using the tails provided. There is a 190 mm space between the valves and the wall to make these connections. Connecting the boiler to the system - Hinge down the front panel (fig. 11) to access to the valve connections - Remove the yellow caps and connect the boiler to the taps using washers provided in the plastic bag 3 x fibre washers for the C/H flow, hot water outlet and cold supply inlet 1 x washer mesh filter F CH return connection. 1 x rubber washer R for gas connection. Provision must be made to fill and recharge the system pressure. This can be achieved using a filling loop or other methods approved by the local water authority.

Fig. 11

Fig. 12 Safety valve The pressure relief valve tube is clear silicone. It should terminate below the boiler over a tundish or 22 mm pipe (see I fig 12) which should in turn discharge safely outside the premises. Care should be taken that it does not terminate over an entrance or window or where a discharge of heated water could endanger occupants or passers by. The system should be carefully checked for leaks, as frequent refilling could cause premature system corrosion or unnecessary scaling of the heat exchanger. Fitting the Horizontal Flue The instructions for the vertical and biflux (twin pipe) flue options are included with the relevant adapter kits. The standard flue supplied with the appliance is suitable for lengths from 300 mm minimum to 790 mm maximum. This means for rear flueing, the standard kit will accommodate a maximum wall thickness of 600 mm, and for side flueing a maximum wall thickness of 587 mm. This takes into account the minimum appliance side clearances of 5 mm. If the fixing is a rear exit flue, the template provides the position of the centre for drilling the flue hole with a core drill. If the flue is a side exit installation then calculate the position of the hole with a slope of 5 mm / metre away from the boiler to the terminal. The flue should fall slightly to the terminal. Making the Electrical Connections Connect the live and neutral wires of the main cable. Note: The connections should be made so that should the lead be pulled from its anchorage, the current carrying wires become taut before the earth wire. If using a room thermostat or other external control, undo the two retaining screws B, remove cover V (fig 15), they can be connected in place of the link on the multipin plug.C. Connect multipin plug into the socket on the power board. Replace the cover.

System Guidance
Fernox Manufacturing Britannica Works Clavering Essex CB11 4QZ Tel: System Controls
The boiler is suitable for sealed systems only. The maximum cold water mains pressure for the appliance is 10 bar. All fittings and pipework connected to the appliance should be of the same standard. If there is a possibility of the incoming mains pressure exceeding 10 bar, particularly at night, then a suitable pressure limiting valve must be fitted. The boiler is designed to provide hot water on demand. If there is a requirement for greater demands, for example if the property has several bathrooms and cloakrooms, a vented or unvented hot water storage system should be used. Showers Any shower valves used with the appliance should be of a thermostatic or pressure balanced type. Refer to the shower manufacturer for performance guidance and suitability. Flushing and Water Treatment The performance of the appliance could be impaired by system debris or the effects of corrosion. The system must be flushed thoroughly to remove metal filings, solder, machining oils and other fluxes and greases before connecting the boiler. If it is an existing system, an appropriate flushing and descaling agent should be used. Refer to BS 7593 (1992) for guidance. For more information on the use of corrosion inhibitors, flushing and descaling agents, advice can be sought from the manufacturers of water treatment products such as: Betz Dearborn Ltd Foundry Lane Widnes Cheshire WA8 8UD Tel: 5351

The boiler is electrically controlled and is suitable for most modern electronic time and temperature controls. The addition of such external controls can be beneficial to the efficient operation of the system. The boiler connections for external controls are 24V and so only controls of 24V or that have voltage free contacts should be used. By pass and Pump The boiler is fitted with an automatic by pass. Although adjustment is not necessary. Expansion Vessel The expansion vessel is pre-charged to 0.7 bar (10 lb/in2). The vessel is suitable for systems up to 145 litres capacity. For systems of greater capacity an additional expansion vessel will be required. Refer to the chart below and BS 7074 pt 1 or BS 5449. Filling Point Provision must be made to be able to charge the system on commissioning and to make up any subsequent pressure loss. The method of connection must utilise approved equipment and must comply with the water regulations. A filling loop can be so installed as to be hidden beneath the boiler.

When there is a demand for heating (either from the room thermostat or the clock) and the boiler temperature control is calling for heat. The pump starts and at a flow rate of 4 Itr/min the central heating flow switch operates allowing the ignition sequence to begin. The first stage solenoid 12a Fig. 7 and safety solenoid 12c Fig. 7 open together to allow gas to the burner. The ignition sequence begins and a continuous high speed spark ignites the gas. As soon as a flame is detected the orange indicator bulb b 23 Fig. 6 will light. After 45 seconds the second stage solenoid 12b Fig. 7 opens to allow the full gas rate. If a flame is not detected, after 8 seconds, the security solenoid closes and shuts off the gas. The red lockout indicator bulb * 24 Fig. 6 will light. The central heating flow temperature is controlled by the central heating control thermistor 16 Fig. 7. The boiler has been designed to minimise cycling and will not attempt to relight for at least 3 minutes after the boiler thermostat has been satisfied. When the room thermostat is satisfied the burner will switch off and the pump will remain running for a further 3 minutes before it to stops. NB It is possible to override the 3 minute delay by pressing the RESET button 25 Fig. 6.
Location The boiler can be installed on any suitable internal wall. Provision must be made to allow the correct routing of the flue and siting of the terminal to allow the safe and efficient removal of the flue products. The appliance may be installed in any room, although reference must be made to the IEE regulations if it contains a bath or shower. A compartment or cupboard may be used provided that it has been purpose-built or modified for the purpose. Provision must be made for permanent ventilation. Detailed recommendations are given in BS 5440 pt 2. If it is proposed that it is installed in a timber framed building then reference must be made to British Gas Document DM2, or advice sought from CORGI. Flue The boiler must be installed so that the flue terminal is exposed to the free passage of external air at all times. It must not be allowed to discharge into another room or space such as an outhouse or closed lean-to. The minimum acceptable clearances are shown below: -A -B -C -D -E Directly below an opening, window, etc Below gutters soils pipes or drain pipes Below eaves Below balconies or car port roof From a vertical drain pipe or soil pipe 300 mm 75 mm 200mm 200 mm 75 mm

It may be necessary to protect the terminal with a guard if it is accessible and could be damaged. Reference should be made to the Building Regulations for guidance. Suitable guards may be obtained from the following maufacturer: Quinnel Barret & Quinnel Wireworks Old Kent Road London SE1 NL Tel: 1357 Ventilation The room in which the boiler is installed does not require specific ventilation. IF IT IS INSTALLED IN A CUPBOARD OR COMPARTMENT PERMANENT VENTILATION IS NOT REQUIRED FOR COOLING PURPOSES. If vents are installed, they must communicate with the same room or be on the same wall to outside air.
outside air. Gas Supply The gas installation and soundness testing must be in accordance with the requirements of BS 6891.The boiler requires: 2.74 m3/hr and a 22 mm supply. Ensure that the pipe size is adequate for the demand including other gas appliances on the same supply. Electrical Supply
The appliance requires an earthed 230V - 50 Hz supply and must be in accordance with current I.E.E. It must also be possible to be able to completely isolate the appliance electrically. Connection should be via a 3 amp fused doublepole isolating switch with contact separation of at least 3 mm on both poles. Alternatively, a fused 3 Amp. 3 pin plug and unswitched socket may be used, provided it is not used in a room containing a bath or shower. It should only supply the appliance.
The boiler is suitable for sealed systems only. The maximum working pressure for the appliance is 10 bar. All fittings and pipework connected to the appliance should be of the same standard. If there is a possibility of the incoming mains pressure exceeding 10 bar, particularly at night, then a suitable pressure limiting valve must be fitted. The boiler is designed to provide hot water on demand to multiple outlets within the property. If there is a requirement for greater demands, for example if the property has several bathrooms and cloakrooms, a vented or unvented hot water storage system may be used. Showers Any shower valves used with the appliance should be of a thermostatic or pressure balanced type. Refer to the shower manufacturer for performance guidance and suitability.

on the use of corrosion agents, advice can be water treatment products Ltd
Fernox Manufacturing Britannica Works Clavering Essex CBll 4QZ Tel: System Controls
Flushing and Water Treatment The performance of the appliance could be impaired by system debris or the effects of corrosion. The system must be flushed thoroughly to remove metal filings, solder, machining oils and other fluxes and greases before connecting the boiler. If it is an existing system, an appropriate flushing and descaling agent should be used. Refer to BS 7593 (1992) for The boiler is electrically controlled and is suitable for most modern electronic time and temperature controls. The addition of such external controls can be beneficial to the efficient operation of the system. The boiler connections for external controls are 24V and so only controls of 24V or that have voltage free contacts should be used.
By pass and Pump The boiler is fitted with a pre-adjusted by pass. Although adjustment is not normally necessary, the by pass can be reset by turning screw ( D Fig. 9 ) anticlockwise to open the by-pass using the chart below for guidance. If used on a system with thermostatic radiator valves, the flow rate with the thermostatic valves closed should be adjusted to at least 100 I/hr.The chart below indicates the residual head of the pump available for the system.

Please check that you are familiar with the installation requirements before commencing work.(section 6) Installation The installation kit included with the flue components comprise following items : - Hanging bracket - A paper template (showing the dimensions of the boiler with 5 mm side clearances, fitting instructions and commissioning instructions) - Connection tails - Screws and wall plugs - Connection washers and filters - Pre-piping jig - Installation manual Method of positionning the boiler on the wall. The paper template can be used to ensure the correct of kitchen cabinets etc. It also details the positioning commissioning instructions. The paper template has to be fixed to the wall and used to fix the position of the hanging bracket, the centre for the flue hole and, if required, the fixings for the pre-piping jig.

Drill and plug the wall and secure the hanging bracket using the screws provided. Remove the boiler from its packaging as shown in Fig. 13 and remove the outer case as shown in Fig.1 4. Place the boiler on the wall on the hanging bracket. If required, there is space for all piping to pass behind the

boiler. Using Fig. 15 for reference, connect the gas and water pipes to the valves located at the base of the appliance using the tails provided. There is a 190 mm space between the valves and the wall to make these connections. Provision must be made to fill and recharge the system
pressure. This can be achieved using a filling loop or other methods approved by the local water authority. The pressure relief should terminate below the boiler over a tundish or 22 mm pipe (see I fig 15) which should in turn discharge safely outside the premises. Care should be taken that it does not terminate over an entrance or window or where a discharge of heated water could endanger occupants or passers by. The system should be carefully checked for leaks, as frequent system corrosion or refilling could cause premature unnecessary scaling of the heat exchanger. Fitting the Horizontal Flue The instructions for the vertical and biflux (twin pipe) flue options are included with the relevant adaptor kits. The standard flue supplied with the appliance is suitable for lengths from 300 mm minimum to 610 mm maximum. This means for rear flueing, the standard kit will accommodate a maximum wall thickness of 490 mm, and for side flueing a maximum wall thickness of 477 mm. This takes into account the minimum appliance side clearances of 5 mm. If the fixing is a rear exit flue, the template provides the position of the centre for drilling the flue hole with a core drill. If the flue is a side exit installation then calculate the position of the hole with a slope of 5 mm / metre to the outlet.
