6. Keep screws away from the top of the timber / fascia board as this will avoid splitting the wood / plastic fascia You should use 10x1.25 screws to fit guttering with two in each bracket .Or one 14 x 1.25 screw should suffice.
Before fixing gutters you should lubricate all seals this makes fitting the clips 100 percent easier if you do not have any silicone spray and the clips are tight a small smear of washing up liquid will help.
Ensure gutters are only fitted up to the cut lines as indicated inside the fitting this allows adequate room for the gutter to expand and contract.
To fit the gutter start at the out let insert the back edge first up under the retaining clip then push down ward until the front clip fits tightly into place
Ensure the back clip has remained in position and double check the gutter is in the marked position .allowing for expansion and contraction.
Now add a union to add the next piece of gutter, and repeat the process until all fittings are in place.
Add stop ends to the end
