GENERAL

If you have pre-customised this work section using the "questions and answers" provided as part of the downloading process, it may be necessary to amend some clauses to suit the final project-specific version.

 

The section must still be checked and customised to suit the project being specified, by removing any other irrelevant details and adding project-specific details and selections.

 

This section relates to Marley rainwater disposal systems.

It includes;

Modify / expand this clause to suit requirements of this specification section.

 

The word 'spouting' is used here to describe any roof guttering which is bracketed off the roof edge or fascia, as against an internal 'gutter', which may or may not be formed as an integral part of the roof cladding.

 

Some specifiers prefer to group general rainwater plumbing work - such as flashings to roof penetrations, windows, etc - together with the supply and installation of spouting and downpipes.  While this can be a convenient arrangement, especially on smaller projects, there are dangers in such an approach, in potentially affecting guarantees or manufacturer's warrantees on roofing and/or window work.  In terms of co-ordination, such flashing and sealing work is also best grouped with the primary enclosure element concerned.

It is important to ensure that all personnel on site have access to accurate, up to date technical information on the many products, materials and equipment used on a project. In most cases individual products are not used in isolation, but form part of a building process. Also a particular manufacturer's and/or supplier's requirements for handling, storage, preparation, installation, finishing and protection of their product can vary from what might be considered the norm. Access to technical information can help overcome this potential problem.

EXECUTION
Conditions
3.1
HANDLING AND STORAGE

Handle and store Marley downpipes, spouting and accessories to avoid damage.  Store on site under cover, on a clean level area, stacked to eliminate movement and away from work in progress.  Store out of direct sunlight. Refer to Marley installation guides for further details.

3.2
SUBSTRATE

Check that fascias, barges or cladding are level and true to line and face and will allow work of the required standard without distortion to the product alignment.  Do not proceed until they are up to standard.

3.3
THERMAL MOVEMENT

Make adequate provision in the jointing of the spouting for thermal movement in the length of the spouting by using Marley expansion joiners and/or expansion outlets.  Refer to Marley expansion technical information.

3.4
ENVIRONMENTAL

Marley Spouting and Downpipe systems are suitable for most environmental conditions and will never rust, rot or corrode.

ESD Note:  Marley spouting and downpipe systems are manufactured using Best Environmental Practice (BEP) and can achieve positive credits under the NZ Green building Council's Green Star rating system for commercial buildings. Refer to www.marley.co.nz/about-us/environment/bep/ for further information.

3.5
RECYCLING

All Marley manufactured spouting and downpipe systems are 100% recyclable and Marley operates recycling programs with industry suppliers where uPVC pipes can be returned from site for recycling at Marley.

Application

Marley spouting is designed as a modular system.

3.6
INSTALL MARLEY SPOUTING

Install to Marley's current published installation instructions available at www.marley.co.nz.  Ensure only Marley MCS® Solvent Welding Cement to be used in conjunction with the spouting systems to manufacturer's instructions.  From high points fix brackets true-to-line to give a fall of 5mm every 10 metres to outlets.  Set spouting brackets at 500mm centres; reduce to 300mm spacing for high wind zones or areas subject to occasional snowfalls.  Make adequate provision for thermal movement.

3.7
INSTALL MARLEY DOWNPIPES

Install to Marley's current published installation instructions available at www.marley.co.nz.  Ensure that all joints are sealed properly using Marley MCS® Solvent Welding Cement.  Assemble downpipes, solvent cement jointed complete, fit to outlets, fix with pipe clips every 1.2 metres, fix pipe clips with 304 stainless steel screws, plumb and discharging into the stormwater gully or pipe inlet to the Marley required practice.

For wet systems when downpipes are holding water for a prolonged period of time and are therefore subjected to head pressure, only round downpipes are suitable.  Marley does not recommend uPVC downpipes be buried, instead Stormwater/DWV pipe should be used for this application.

Painting Marley uPVC spouting/downpipes
3.8
PAINTING

After installation use a mineral based undercoat and two coats of 100% weatherable acrylic paint.  Do not paint the inside of spouting or internal brackets.

Delete this clause when not painting the Marley uPVC spouting system.
