11 Information about pellet hoses
Suitable pellet hose
DN50 pellet hoses with copper litz wire (for earthing)
are required for the suction and return air.
Minimum bending radius: 250 mm
The minimum bending radius for pellet hoses is
250 mm.
If the radius is below this value, the cross section of the
pellet hose is reduced and the friction on the inner
walls increases. As a result, the pellets are damaged,
blockages can occur and the service life of the pellet
hose is reduced.
Installation tips for pellet hoses

Fig. 11-3: Avoid twisting pellet hoses
Fig. 11-4: Use pipe guides or pipe supports
Single-piece suction hose
The suction hose for the pellets must always consist of
a single piece.
Suction hoses made from several parts have higher
friction on the inner walls, which can result in damage
to the pellets.
Only the pellet hose for the back air may be made
of multiple parts.
Straight paths
Lay out the pellet hoses as straight as possible.
Suction hoses laid out in loops have higher friction on
the inner walls, which can result in damage to the
pellets.
Do not attach pellet hoses to the tilted floor
structure
In the store room, do not attach pellet hoses to the
tilted floor structure or guide them to it. In this way,
noise transmission is prevented from the pellet hoses
to the tilted floor structure and noise lelvels are
reduced.
Earthing
The pellet hoses must be earthed as they acquire an
electrostatic charge during pellet transport. A copper
litz wire is moulded into the pellet hoses for earthing.
