25 Fig. 6 20 Central Heating To be able to supply heating, the selector switch 19 fig. 6 must be turned fully clockwise to ‘ffff position. This will be confirmed by the green indicator light 0 22 fig. 6. When there is a demand for heating (either from the room thermostat or the external programmer) 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.
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 9 24 fig. 6 will light. The central heating flow temperature is controlled by the central heating control thermistor 16 fig. 7.
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.
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 SE15 1NL Tel: 0171 639 1357 Ventilation The room in which the boiler is installed does not require specific ventilation.
Please check that you are familiar with the installation requirements before commencing work.
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 Fitting the Horizontal Flue The instructions for the elevated horizontal, vertical and biflux (twin pipe) flue options are included with the relevant adapter kits.
Connecting of the boiler to the system - Hinge down the electrical box to gain access to the valves connections. Push in the tabs (P Fig 19) on either side of the boiler and pivot the box forward. - Remove the yellow caps from connecting pipes and connect the boiler to the taps using gaskets provided in the plastic bag. Rubber washer “R” for gas connection.
Making the Electrical Connections Hinge down the electrical box to gain access to the electrical connections. Push in the tabs (P fig. 19) on either side of the boiler and pivot the box forward. Undo the two retaining screws, remove cable clamp. (A fig. 19) remove cover and Connect the live and neutral wires to the multipin plug leaving sufficient earth wire to connect to the earthing point. (B fig. 20).
connector 1 2 Fig. 20 C If using a room thermostat or other external control, they can be connected in place of the link on the multipin plug (fig 21). Connect multipin plug onto into the socket on the power board. Secure the cable using the cable clamp and replace the cover. Earth pillar Fig.
Pre-commissioning Ensure that the system has been adequately flushed. Purge gas supply of air and test for soundness. Carry out final electrical tests to ensure the correct polarity and earthing continuity. Central Heating Open flow and return valves on the boiler.{18 and 29 Fig. 22) Open the automatic air vent (6 Fig. 23) Fill system and vent radiators. Set system pressure and remove filling loop. Check for leaks. Manually check pump is free to turn. Switch on electrical supply.
(see separate servicing leaflet for details) Set the by pass (Refer to system guidance) Re-flush the system to remove any dissolved oils and fluxes. Recharge system pressure and introduce any water treatment as required. Post Commissioning 43 - / /6 Ensure system pressure has been set correctly. Set the by pass. Set boiler thermostat and controls. Set programmer to householder’s requirements. Set external controls. Handing Over to the Householder 19 \ 21 - Fig.
The boiler is suitable for sealed systems only. The maximum working pressure for the appliance is 3 bar. All fittings and pipework connected to the appliance should be of the same standard. 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.
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 l/hr.The chart below indicates the residual head of the pump available for the system. Head and flow rate available m Fig.
Expansion Vessel Filling Point The expansion vessel is pre-charged to 0.7 bar (10 Ib/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. 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.
