[. . . ] Use at least one bracket for each extension used. Ensure that all inner flue connections have a good fit/seal, and that the space clips in each extension are correctly positioned. 5. 8 5. 8. 1 REASSEMBLE BOILER AS PER (sect. 5. 6. 1) Fitting valves pack Remove plastic caps from boiler connection and fit flanged copper tail and valves as per Fig. 46) A minimum gas pressure of 20 mbar (8 in wg. ) must be available at the boiler inlet at full flow rate. Fit gas service cock to the boiler via the union nut and connect gas pipe. Do not overtighten and use another spanner as a counter force to avoid straining internal connections. 46) Before any central heating connections are made to the boiler all system valves should be opened and the system thoroughly flushed out with cold water. - Connect the central heating return pipe to the isolating cock marked CHR. - Connect the central heating flow pipe to the isolating cock marked CHF. - Pipe dimension's and position are marked on template supplied and Fig. 49A 5. 11 5. 11 . 1 DOMESTIC HOT WATER (Fig. 46) The domestic hot water circuit does not need a safety valve but it is essential to ensure that the pressure of the cold water supply does not exceed 10 bar. If in doubt it is advisable to install a pressure reducing valve. The minimum pressure needed to operate the domestic hot water system is 0. 5 bar with a flow of approx 3 Lts. The regulator screw on the cold water outlet of the diverter valve may be adjusted to prevent excess volume flow (Fig. Flush out all foreign matter from the supply pipe before connecting to the appliance. cold water pipe to the stop cock to the appliance inlet marked DCW. hot water pipe with a suitable connection. SAFETY VALVE DISCHARGE The safety valve is located near the pump. It has a threaded outlet RC l/2" (to 15 mm copper) to permit a discharge pipe to be connected. When connecting ensure the discharge pipe does not restrict access. [. . . ] Spacing Clips Spacing clips are available on request should they be required. Sampling point Sampling point is positioned on the outlet of the twin flue header for the use of sampling gas combustion products. Vertical eccentric flue exhaust duct Condensing trap To drain the exhaust pipe only with a greater distance of over 6 metres, a condensating trap must be fitted, or as an alternative to this the sampling point may also be used as a condensating drain should this be required. Exhaust/suction system with concentric pipes for flat or sloping roofs. Maximum distance D = I + E + T = 14 metre + 14 metre + 1 metre = 29 metre maximum (pipe + terminal). NOTE: The pressure loss for each elbow fitted is: 90" elbow less 4 metre of pipe length for each one fitted. [. . . ]
