Pour water into flue duct (to fill condensate trap) 5.4 FIT THE BOILER - Refer to Figs. 5.2 and 5.3 Lift the boiler and locate it on the mounting bracket - the boiler should be lifted by two persons. Note: When handling or lifting always use safe techniques - keep your back straight, bend your knees, don't twist - move your feet, avoid bending forwards and sideways and keep the load as close to your body as possible. Where possible transport the boiler using a sack truck or other suitable trolley. Always grip the boiler firmly, and before lifting feel where the weight is concentrated to establish the centre of gravity, repositioning yourself as necessary.
Location for wall mounting bracket on rear of boiler Appropriate personal protective equipment should be worn. Fig. 5.3 - rear of boiler 5.5 CONNECT THE PIPEWORK - Fig. 5.4 1. Thoroughly flush out all the water pipework. Refer to Section 3.9. 2. Fit the valves to the boiler connections as shown in Fig. 5.4 - note the colours of the operating levers. 3. Connect the system pipework to the union fittings on the valves just fitted. Note: When soldering bends, ensure they are not connected to the valves, otherwise the internal seals may be damaged. One metre of copper pipe must be fitted to the boiler before connecting to any plastic pipework conforming to BS 7291. 4.
Connect the flexible condensate pipe to the rubber connector as shown in Fig. 5.4. Using the adaptor supplied, connect the flexible pipe to the condensate drain. Ensure that the condensate discharge pipe is as required in Section 4.10. 5. Ensure that all the valves are closed (operating lever at right angle to valve) and do not turn on the water or gas supplies at this stage.
