Information about pellet hoses
11
On the ends of the pellet hoses, free around 5 cm of
copper litz wire from the hose and bend it inwards into
the hose.
This establishes a contact between conveyor and the
boiler. At the boiler, the copper litz wires are clamped
to the earthing cable near the pellet hose attachment
nozzles.
No contact with uninsulated heating pipes
The pellet hoses are designed for a temperature range
of -15°C to +60°C, so they may not come into contact
with uninsulated heating pipes.
UV protection outdoors
When pellet hoses are installed outdoors, they must be
enclosed in a protective conduit to protect them from
ultraviolet radiation. If the pellet hoses are not
protected, they can become brittle, leading to a
reduced service life.
