RainGain Gutter 125mm x 2.45m - White

1. Measure around the building

To determine the length of gutters needed, measure around the building. Remember to allow 150mm extra for all external corner mitres and 100mm for each overlap in the gutter.
Predetermine the location of your downpipe outlets.

2. Assemble pre-cut gutter lengths on the ground

Connect the two gutter sections by cutting back 100mm on the front lip of the gutter & slide the second piece inside (in the direction that water needs to shed).
To cut the gutter length, use a set square to mark out your cut line. Make use of a thin metal cold cutting blade or tin snips to make a clean cut.
The cut end should always face outwards.
Join the pieces by inserting sealant in the joints.
Predrill holes. Join the ends with a sealed rivet.
Use two rivets/screws on each side at the top of the
joint.

3. Install gutter brackets

With the gutter assembly complete, space out the gutter brackets inside the gutter, based on the truss/rafter spacing and add one bracket between these (total distance between brackets should be 500- 700mm).
These brackets fit under the front lip of the gutter & slide over the back of the gutter.
It is easier to install these on the ground before lifting the gutter in place.

4. Assemble stop ends

Apply stop-ends to the gutter lengths where you require the flow of water to stop.
Stop-ends are either left or right-handed.
Apply sealant to the inner perimeter before fastening to the end of the gutter.
To fasten: predrill holes & use sealed rivets to hold the stop-end in place. Use two rivets on each side, one on top & one on the bottom.

5. Cut holes for the downpipes in the gutter

Using a piece of the downpipe, trace the outline of the downpipe on the bottom of the gutter where you want the section installed.
Create an X within the traced line.
Predrill holes in each quadrant & use a metal cold cutting disc to cut along the X.
Push the cut pieces down to create an outlet for the downpipe to fit over.

6. Line-up gutter

To ensure a straight line when hanging a gutter, make use of a nail & string line/chalk line along the edge of the roof to serve as a guide when installing the gutter.
The gutter should shed water in the direction of the downpipe. Therefore, consider approximately 15-30mm of slope over the total installed gutter length.

7. Hang the gutter

Slide the gutter (with brackets inside) in place, to line up with the pre-marked line.
Fasten the brackets using the appropriate fasteners as indicated below.
Be aware of the fact that there can be 2 different fasteners required to hang a single gutter length, due to the difference in the truss and inter-truss materials.
