Pellet store Filling nozzles
73
Only in exceptional cases - when no narrow wall
of the pellet store is accessible from the outside -
can the filling nozzles be positioned on the longer wall.
Each half of the room needs its own nozzle with an
impact protection mat on the opposite side. The disad-
vantage is that halfway through the filling process, the
hoses must be exchanged.

Anchoring the filling nozzles
The filling nozzles must be firmly anchored in the wall
so they can withstand the movements of the hoses
from the delivery vehicle and cannot rotate when the
hoses are attached. Mount the filling nozzles horizon-
tally 200 mm under the ceiling of the pellet store so that
the pellets are not blown against the ceiling.
To install the filling nozzles in smooth holes or sewer
pipe cut-outs so they cannot twist, the ETA filling
nozzles are equipped with a flange that transfers the
forces directly into the wall via 4 screws.
ETA filling nozzles with 100 mm diameter fit exactly in
the cut-outs made for fitting a sewer pipe with 110 mm
outside diameter. The small gap between nozzle and
wall can be sealed with silicone; for larger gaps, foam
is used.

If the filling nozzles are installed below ground in an
area, ensure that the hose can be led out of the area in
a straight line. Angled filling nozzles are available for
this situation.

If an extension of the fill line is required, keep it as
short as possible to prevent friction loss while
filling.
The lever for tightening the coupling, around
300 mm long, needs a working range of 120°.
