1. Ensure the flue seal collar B is located onto the flue assembly A. 2. Position the roof flashing plate D (supplied separately) over the hole cut in the roof and insert flue assembly A from the roof end. 3. Remove the casing top blanking plate and gasket and refit to the boiler rear flue hole. 4. Fit the boiler vertical conversion kit (to be found in the vertical connector kit). Refer to Frame 26 No's 2 to 7. 5. Push fit the vertical connector E (supplied separately) into the boiler flue connection and retain with the four securing screws provided. 6. "Push" fit extension duct F (if required (supplied separately)) and the roof flue kit assembly A into the vertical connector E. 7. If the last extension duct requires cutting, measure the distance (outer ducts) between the duct and the terminal and add 100 mm to this dimension. This gives the length of the last extension duct. Note. Check the position of the inner flue duct relative to the outer duct on the assembled extension duct(s) and ensure the terminal flue duct is cut longer than the air duct to ensure engagement in the final flue duct seal. 8. Slide down and position the flue seal collar B over the roof plate D and secure it with the 3 screws C to the flue assembly A. 9. Finally ensure the roof flashing plate D is correctly sealed to the roof.

Remove the plastic plugs from the flow and return pipes. 2. Make all water connections and check for water soundness. 36 GAS CONNECTION Refer to 'Gas Supply ', page 8. Refer to Frame 2 for gas inlet service dimensions. A minimum pressure of 20 mbar MUST be available at the boiler inlet with the boiler operating. The main gas cock is on the left hand side of the gas control valve, as shown. To facilitate connection the gas cock may be removed from the gas control valve. 38 CONDENSATE DRAIN Refer also to the British Gas document: 'Guidance Notes for the Installation of Domestic Gas Condensing Boilers' (1989). The boiler comes with a built in condensate siphon trap. The boiler condensate drain must be connected to a drainage point, preferably within the building. This condensate drainage should be run in standard 21.5mm overflow pipe. Connection to the boiler is made by fitting the siphon nut and sealing washer to the threaded siphon outlet. Ensure that the condensate siphon is full of water before commissioning the boiler. Refer to Frames 19 and 27. The routing of the drain must be made to allow a minimum fall of 1 in 20 away from the boiler, throughout its length. The drainage pipework must be arranged so that obstruction (e.g. through freezing) of external drainage pipes does not give rise to spillage within the dwelling. cla7644 Front View Side View 70mm (2 3/4") 38mm (1 1/2") Condensate siphon drain BOILER cla7771 75mm trap Sink constitutes air break DRAIN Ground Level Open end of pipe direct into gulley below grating but above water level cla9252 75mm trap DRAIN Sink Ground Level Open end of pipe direct into gulley below grating but above water level Air Break 1.

If excessive external pipework cannot be avoided a condensate removal pump (available as an option) and insulation are recommended to prevent possible freezing. All pipework and fittings in the condensate drain system must be made of plastic. No other materials may be used. The drain outlet on the boiler is standard 21.5mm overflow pipe. This size must not be reduced in any part of its length.
