Distribute suction wands along the floor
of the pellet storage area, so that the
room is emptied evenly.
The distance of the wands to the walls of
the storage area should be approx. half of
the distance between wands (see
500 mm
adjacent diagram).
The dimensions shown are only
examples. Select appropriate distances
for storage areas with alternative
dimensions.
Create a wall opening in the storage area
in accordance with the adjacent diagram.
Close the gap between the wall opening
and the fitted changeover unit with
fire−resistant material (e.g. rendering/
plaster).
