Now that the solar fan base is secured you will need to cut the lengths of
bitumen impregnated foam to seal between the tiles and the solar fan
base plate. Cut a length for the top of the solar fan base plate and push in
under the tile across the top. Apply silicone to seal.
Cut a length for each side of the solar fan base plate. The left hand side
will be installed after the cut tiles are installed at a later stage. The right
hand side will be installed at this stage.
Apply silicone to the right hand side of the solar fan base plate ready for
the bitumen impregnated foam to be fitted.
Apply the bitumen impregnated foam to the right hand side of the solar
fan base plate. This will now sit under the high part of the tiles that will be
re-installed. Do the same to the left hand side of the solar fan base plate.
Re-install the bottom tile and slide the tile above back down.
Take 2 of the tiles that have been removed in the early stages and prepare
them to be cut to increase the overlap of the tiles on the left hand side of
the solar fan base plate. Mark a line on each tile that would leave approx
20-30mm clearance from the intersection of the solar fan base plate and
the exhaust neck.
