What to do if the NBE Boiler displays an 'Alarm no fuel' message?
- R
  Robert ZhangAug 19, 2025
  If the NBE Boiler shows an 'Alarm no fuel' message, it could be due to several reasons. First, check if the hopper is empty and fill it with wood pellets before restarting. Another possible cause is that the flame has gone out during operation, in which case you should make a new adjustment of the burner. Also, a defective photo sensor might be the reason, so consider changing it. Finally, an unstable fuel supply due to sawdust in the auger/hopper can cause this alarm; try emptying the auger/hopper.

  If your NBE Boiler is showing an 'Alarm ignition', there are a few potential causes. It could be due to a defective ignition, in which case you should replace the electrical igniter. Also, check if the ignition or the burner grate is located or fitted incorrectly and mount it correctly. Furthermore, too high a chimney draft can cause this issue, so consider installing a draft stabilizer in the chimney. You might also want to set the electric ignition power up or reduce the fan speed during ignition. Finally, verify the fan is running, and replace it if necessary.

What to do if my NBE RTB 10 Boiler experiences smoke setbacks?
- E
  Erin VillaAug 25, 2025
  Smoke setbacks in your NBE Boiler can occur due to several reasons. A lack of draft in the chimney might be the cause, so insulate the smoke pipe or increase the chimney height. You might also need to submerge a liner in the chimney or increase the temperature of the smoke. If the drop shaft sensor is defective, change the temperature sensor on the burner print. Unfavorable wind conditions can also cause this, so increasing the chimney height might help. Additionally, closing doors or making the intake on the same side as the chimney might resolve the issue.

  If your NBE Boiler is displaying an 'Alarm temperature boiler', it could be due to a defective temperature sensor, so you should change it. Ensure the temperature sensor hasn't fallen off the boiler; if it has, mount it correctly, attaching it with a cable tie. If the power is too low for your house, make a new adjustment of the burner. You might also need to adjust the alarm limit down or add more power to the burner if possible.

- T
  Tyrone PowellAug 27, 2025
  High pellet consumption in your NBE Boiler can be attributed to several factors. Lean burning is one potential cause, so make a new adjustment of the burner. Another reason could be too high a chimney draft, which can be resolved by installing a draft stabilizer in the chimney. Additionally, uninsulated pipes in the installation can lead to increased consumption, so insulate them with pipe insulation.

What causes an 'Alarm hot drop shaft' in my NBE Boiler?
- A
  Ariel SchwartzAug 30, 2025
  An 'Alarm hot drop shaft' in your NBE Boiler can be caused by several factors. Cinders in the burner head may be the issue, requiring more air for combustion. Back pressure in the boiler can also trigger this alarm, so you should clean the boiler. A lack of draft in the chimney might be the cause, so increase the chimney height. Ensure you clean the burner head regularly and consider switching to better quality wood pellets.

What causes cinders on the grate of my NBE RTB 10?
- J
  Jason WallaceSep 3, 2025
  Cinders on the grate of your NBE Boiler can be due to several reasons. Insufficient blower cleaning may be the cause, so adjust the fan % up to clean and the time between cleans down. Clean the grate mechanically more frequently. Poor quality pellets can also cause this issue, so change supplier. Consider mounting compressor cleaning or changing the grate to a more open model. Fat combustion might be the problem, so adjust the fan up at 10, 50, and 100% power. You can also adjust the burner power down in 'auto calculation'.
