10. Tile Roof Installation: (Above the tile) SAV-20 & SAV-20T
*The SAV-30 has a different base plate and ventilation opening size. This will require different measurements and
allowances to those shown here for the SAV-20 & SAV-20T.
Remove 4 x tiles and slide up the two top tiles. This should allow enough
opening for installation. However as there are variances in the different
styles and sizes of tiles, this may need to be adjusted.
Prior to taking the solar fan onto the roof, make a cardboard cut-out to
cover the solar panel so that the fan does not activate during the
installation process. Place the solar fan over the opening that is created by
the removal of the 4 roofing tiles. You can temporarily hold it in place by
securing a strap thru the centre top hole in the base place to the exposed
batten.
Mark a line on the tiles showing the outside edge of the solar fan base
plate. This will show you the outline of the base plate when the solar fan is
temporarily removed. Ideally the solar fan base plate should have equal
over-hang on each side. The top of the base plate will line up with the
bottom of the row of tiles where you have previously slide them up from.
Blue lines show the tape markings on the tiles showing the outline of the
base plate. The base plate location is marked for illustration by the dotted
red lines.
(Picture-5) You will need to measure the distance between the rafters for
the 2 x timber supporting braces you will require. These 2 x braces will
mount on top of the trusses. A 3rd brace will be the width of the opening
of the tiles at the bottom. These braces will provide an incredibly strong
and convenient securing point for the solar fan base plate. They will most
likely require 35 x 70mm pine for most tile roofs.
(Picture-6) Screw a timber brace across the rafters at the bottom of the
opening. This brace will later have the shorter 3rd brace screwed on top of
it as shown in Picture- 8 & 9.
(Picture-7) Screw a timber brace across the rafter at the top along the line
of the tiles at the top as if they had been slid back down. This will be used
to secure the top of the solar fan base plate.
(Picture-8 & 9) Screw the shorter 3rd brace on-top of the bottom brace.
This should fit inside the opening of the tiles. The bottom of the base plate
will sit on this for securing later.
