ainwater systems installation fixing and connections guide Fixing centres and expansion joints Thermal movement When fixing gutter, allowance must be made for thermal movement and all Geberit Terrain outlets, angles and joint brackets are engraved with the appropriate expansion gaps. It is important that the gutter is correctly fitted into these fittings taking due care to place the cut end of the gutter on the line marked. It is important that the expansion gaps are maintained when gutter is fitted and must not be spaced to exceed 4 metres/13ft centres. In the case of dry jointing downpipe each fitting clip has a sight hole provided on the front of it. The purpose of the sight holes is to allow sight of the top of the pipe being fitted from below. When this pipe end obscures half of the aperture you have the correct expansion gap. The maximum distance between expansion joints should not exceed 5.5 metres/18ft. Applicable to all Geberit Terrain gutter systems and downpipe assemblies. 10 mm expansion gap Fig 1. Maximum 2.0 m pipe supports Maximum 1 metre Maximum 4.0 metres between expansion Joints Maximum 5.5 m between expansion joints Maximum distance between: Gutter support brackets* : 1 metre* Gutter expansion joints : 4 metres Pipe fixing clips : 2 metres Pipe expansion joints : 5.5 metres * NOTE: Support centres for gutters subject to risk of heavy snow fall should be reduced to 800mm (max) 11mm gap 2 For roof outlets Applicable to: 82 mm and 110 mm circular pipework used with roof outlets Maximum distance between: Vertical pipe fixing clips : 2 metres Pipe expansion joints † : 4 metres † † NOTE: Anchor expansion couplings with 140 Pipe Fixing Clip to prevent thermal expansion upthrust from rupturing joint between roof outlet and finish.
