To select the max firing rate: nominal effect level: Press “menu” button repeatedly until “Select powerlevel. Xx
Mbtu” is shown. Change its value by pressing the “-“ or “+” buttons. The output can be adjusted between limits
for modulating effect in steps of 3,000 Btu (normal 20,000 – 78,000 Btu/hr).
To save new value: Press and hold down the “menu” button for 3 seconds.
The max firing rate is the starting point for the burner when running in modulating mode.
4.7 Pellet Filling Before Starting the NH Burner
The external auger can only feed the pellets to the burner if the external storage tank pellet level is above the
external auger’s inlet.
1.
Fill the external storage.
2.
Fit burner to the boiler by using the quick locking latches on each side. Make sure that the gasket
between burner and boiler door is tight when the door has been locked.
3.
Verify power cables from boiler high limit to burner and from external feed motor are connected to their
respective inputs on the burner, check status of the drop tube, turn on power (burner power supply must
also be turned on). After a few seconds “Waiting for pellets” is displayed on the display screen the
external feeding auger starts. This auger stops after 2 minutes if the internal hopper is not filled within
that timeframe. Press the “ON/OFF” button and the auger continues to run. Continue this process until
the correct level is reached. When the internal hopper is full, the level sensor stops the external auger.
NOTE: The main power switch is usually located on the wall next to the boiler or by the entrance to the boiler
room.
Manual Feeding
4.
The external auger can be used manually: Press “ON/OFF” to stop. Scroll menu until you come to
“manual external auger”, then press and hold the “+” button to start the motor. Fill until the burner
internal storage is full. The motor stops when the “+” button is released or when the internal storage
sensor is activated.
NOTE: “Manual external auger” is shown only when burner operation is stopped.
NOTE: Do not touch the dosage auger or the external augers in- or outlet when the external motor is connected.
The capacity sensor activates when the pellet level in the internal storage has fallen below the sensor area.
Under normal running conditions the external auger runs up to 2 minutes after the capacity sensor has switched
on. This control is programmed so that the motor will only run for 2 minutes at a time. If the burner internal
storage has not been filled in this time frame, the indication lamp changes color from green to red and the
“!!ERROR!!! External feed” appears on the display screen.
