be installed is sufciently solid and guarantees the
safe anchorage of the screws.
For the assembly, proceed as follows:
position the boiler support plate (F) on the wall and
use a spirit level to make sure it is perfectly horizontal
mark the position of the holes (ø 6 mm) for securing
the boiler support plate (F)
make sure all the measurements are exact, then drill
the holes using drill tips with the diameters indicated
above
fasten the plate to the wall.
