Feed screw installation
(For PellX feed screws, 1.7 and 2.3 m.)
Check that the screw turns easily in the screw tube. Put the blue pellet tubing on
the angular outlet pipe of the feed screw and fasten it with hose clamps. Mount
the adapter with clamps on the other end of the tubing.
Mount the screw tube in the storage hopper. The screw inlet shall be positioned
at least 100 mm from the bottom and 150 mm from the nearest storage wall and
the inclination to the ground plane between 40° and 50°. Adjust the position of
the screw so that the hose adapter can be pressed into the flame trap tube and so
that the tube has an unbroken slope without being stretched or deformed. The
tube may not be cut to less than 500 mm plus the length for fitting.
The feed screw must be well anchored so that it does not work its way into the
storage hopper. Fasten the screw without deforming the pipe. Most storage
hoppers on the market (intermediate types, week-size types, etc.) are provided
with a connection sleeve that fastens the tube perfectly. Balance the tube by
hanging it with the enclosed suspendor. Put a suitable hook or loop in the roof
and stretch the suspendor between that point and the fixing hole in the end of the
screw tube. Do not stretch too much; the tube may bend.
Mount the screw motor onto the feed screw driver. The M8 bolt with its distance
tube shall stick into the motor plate and lock the motor, which prevents it from
rotating. Ensure that the stop screw fits into the groove on the motor shaft and
tighten the screw.
Connect the supply cable to the socket on the burner.
Independant of manufacture or type of feed screw, it shall not be
possible to come in contact with any moving parts of the screw during
operation. Dependant on each individual installation, it can be
necessary with a safety switch and/or an emergency stop and also a
safety guard. The installation should be secure for children and
animals.
