Calibration of feed dose - Suction version
Calibration of feed dose on a boiler equipped with a suction unit:
When the on board pellets storage has been filled it is time to calibrate the feed rate.
Remove the front casing of the fuel store. The internal fuel store and burner unit will be visual.
Remove the fall shaft connection by removing the elbow coming out from the storage. For refe-
rence see illustration on page 15.
Place a container underneath the hole to the feeding opening where the elbow used to connect
to the storage to collect the pellets that will be fed during a auger filling procedure.
The hole down the fall shaft to the burner (where the black plastic hose where connected origi-
nally) needs to plugged temporarily in order to be able to build under pressure in the fire box and
allow the auger to feed in test mode.
Enter the OPERATION menu and then INSTALLATION menu. Activate the FILL FEEDER function
which will force feed pellets for 15 minutes. Meanwhile the auger is filling up tap the auger repea-
tedly to ensure that it is packed with fuel. When pellets comes out at the end of the auger the fill
feeder should be set back to NO and then directly back to ON to have a full 15 minutes feed of
pellets to make sure enough pellets is in the auger. Collect the pellets in a bag or container during
this 15 minute feed. Do not stop the feeding process, it is critical to have a properly packed and
filled auger in order to calibrate the feed rate in the next step.
A correctly adjusted start dose is one of the most critical and important steps of a
comissioning process. If the start dose is incorrect it will give the wrong output on the
boiler which might create operational issues, excessive wear on parts and even be
dangerous in extreme situations.
