FIXING AND ADJUSTING THE WINDOW
It is important to adjust the square and level of the window to
ensure a weathertight seal between the sash and frame and for
optimum operation.
Start by fixing the bottom frame to the lower installation batten
which should be level.
Adjust distance between frame and sash to ensure an even gap
at each side. Bottom frame and bottom sash must be parallel. If
uneven rafters cause the frame to twist, adjust frame using the
wedge supplied as shown in the installation instructions. If the roof
is not level, eg very lopsided/slanting, see pages 50-51.
Having adjusted the window, fix it as described in the installation
instructions.
