Your tools and materials
Refer to Pg 3 and 4 of the Marley DIY Easy Installation Guide for assistance with
planning and quantifying or visit your local building or plumbing merchant for further advice.
Assemble your scaffold and drop cloth around your work area and ensure appropriate safety equipment is at hand. Check the roof overhang beyond fascia is less than 50mm.
Locate position of downpipe outlet, this will be your low point. On existing houses these are identified by existing downpipes or stormwater outlets.
Next find your high point. Position the first bracket at determined high point as high as possible on the fascia under roof overhang. Secure string line to fascia using a screw adjacent to the first bracket and run under first bracket to low point. Use Fig 1 as reference. Ensure a min fall of 5mm for every 10m of run.
Mark and secure brackets no more than 500mm apart. In high wind or snow prone areas reduce spacing to 300mm. Use a minimum of 3 nails or 3 stainless steel screws per bracket. Minimum screw is 6g x 20mm coarse thread count. NB: Gib clouts must NOT be used.
Position outlet at low point ( in line with drain) and ensure string line aligns with feature on side tabs of outlet. Secure outlet to fascia using a minimum of 4 fixings.
For internal brackets, position front of spouting into front of brackets, then roll spouting into back of brackets until secure. For external brackets, position back of spouting into back of bracket, then roll spouting into front of brackets until secure. Check every bracket is correctly engaged.
Slide spouting into expansion outlet. Ensure end of spouting is aligned with the marking corresponding to the temperature at time of installation
Use spouting joiners and Marley MCS® solvent cement to connect lengths of spouting as necessary. For long runs over 12 metres replace one of the spouting joiners with an expansion joiner to provide further expansion allowance.
When required, solvent weld corners onto correct end of the spouting.
N.B Corners should be supported by brackets either side- 50mm clearance for external corners and 200mm clearance for internal corners.
Check project is safe and complete. Clean any excess Marley solvent cement (MCS®) from corners or joiners to minimise potential pooling of water. Ensure spouting is correctly secured to each bracket and space has been provided for expansion and contraction.
