Installing downpipes and accessories
Intermediate Segment
The length of an intermediate segment of downpipe between two elbows is measured in the following manner. Squeeze the upper elbow (1) onto the gutter collection box directing it towards the assumed point of installation of the downpipe. Hold the lower elbow (2) in the air aiming it at the upper one. The distance between the elbows and the wall should amount to 35 mm. Arrange the elbows so they are in a single line. Use a measure as a straightedge. Measure the distance between the elbows and add 10 cm. Intermediate elements come in 0.5 m segments with narrowed ends. A cut off downpipe may be used in houses with large eaves (Figure No. 12).
Downpipe fasteners
Downpipe fasteners are available in two versions—for timber walls (attached using screws) and for masonry walls with insulation (with a screwed anchor bolt) and non-insulated (with a hammered anchor bolt). The upper fastener should be installed immediately below the elbow. The distance between fasteners should amount to 2 m. It should be made certain that the downpipe is set vertically (Figure No. 13). The fastener should be locked as in the drawing, by rotating the lock 180° (Figure No. 14).
