If after calculating or measuring the overall flueheight from the top of the boiler, it is necessary to cut both pipesof assembly A, then ensure they are cut equally leaving the innerflue tube longer than the outer air tube as supplied.Ensure the cut pipe ends are free from any burrs.1. Position the roof flashing plate (supplied separately) over thehole cut in the roof and insert flue terminal from the roof end.nm8739min 16 omax 41 oMAX LENGTH:7.5mBOILERnm8740Flue TerminalPitched roof tileweather collarFlat roof tileweather collar1nm87412ExtensionDuctVerticalconnectorTurretclamp3nm8743'X'42.

"Push" fit extension duct (if required (supplied separately)) intovertical connector.4. If the last extension duct requires cutting, measure ‘X’, the distance(outer ducts), between the duct and the terminal and add 100 mm tothis dimension. This gives the length of the last extension duct.Note.Check the position of the inner flue duct relative to the outer ducton the assembled extension duct(s) and ensure the terminal flue duct iscut longer than the air duct to ensure engagement in the final flue ductseal.5. Finally ensure the roof flashing plate is correctly sealed to the roof.
