                                            Installation of PVCu gutters, step by step

                                            1  Establish the position of the outlets.
                                            2  Establish the high point of the gutter and fix a fascia bracket at this high point
                                               onto the fascia board using 25 mm × no. 10 zinc-plated roundhead screws.
                                            3  Using a plumb line, centre the outlet over the gully or drain.
                                            4  The distance between the high point and the outlet should be measured and
                                               a fall of 1:600 determined. Using this fall, fix the outlet at the low point on
                                               the fascia board.
                                            5  A line can now be strung between the high fascia bracket and the outlet. For
                                               gutters that are to be fixed level, a spirit level should be used against the string.

                                                                                          Gully

                                            6  Screw further fascia brackets onto the fascia board, working away from the
                                               running outlet. The brackets should just touch the line but not distort it. Most
                                               manufacturers recommend a distance between the fascia brackets of 1 m
                                               (750 mm in areas that suffer heavy snowfall), but the manufacturer’s instructions
                                               should be checked beforehand. There is no need to fix a bracket close to the
                                               running outlet as it is secured using screws and therefore acts as a bracket.
