Troubleshooting
Problem: Auger not feeding pellets
The stove operates, but does not feed pellets.
Solutions:
Ensure that the hopper is full. When the hopper gets low, the pellets can funnel or
bridge, causing a low density feeder problems.
Ensure that the hopper lid switch, and vacuum pressure switches are engaging.
Press the info button ( ! ) to check if Feed, Vacuum, and Limit are engaging.
Auger may have a buildup or jam. Empty the hopper and try to activate the auger in the diagnosis
menu to see if the auger will turn.
*Note: If the auger is making a squeaking or groaning noise, you may want to lubricate the auger system
with a lubricant such as graphite powder or white lithium grease.
Problem: Alarm - Lost Connect
The stove giving a Lost Connect alert means that the panel is receiving power from the
circuit board, but it is unable to communicate with it.
Solutions:
Ensure that the 4-pin data cable is connected snugly into both the back of the
control panel as well as into the bottom circuit board.
Ensure that none of the 4-pin data cable wires have a loose connection at the white plastic connector.
Ensure that the data cable pinout is the same on both sides, and that the Transmit line (TX) and
Receive line (RX) did not get swapped or pinned out incorrectly.
Problem: ERR where room temperature should be
The stove displaying ERR inside the house where the room temperature should be,
indicates that the control panel is not receiving accurate temperature data from the
room temperature thermocouple sensor.
Solutions:
Ensure that the room temperature sensor wire behind the stove is not crushed, cut,
or damaged in any way.
Ensure that the room temperature sensor wire is securely connected to the white jumper connection on
the circuit board. *see wiring diagram
*Note: The stove will still operate correctly when set to the Manual operational mode.
Problem: Temperature getting too warm in the room
If the room temperature is getting too warm, it means that the stove is creating more
heat than the space is losing over time. This is fairly common during mild temperatures
or in the transitional seasons.
Solutions:
Turn the stove off to allow the space to cool down.
Set the stove to a lower temperature (in Temp Mode) to allow the smallest fire
possible.
Set the stove to a lower heat level (in Manual Mode) to allow the smallest fire possible.
If the stove is set to the lowest possible heat level or temperature and is still overheating the space, you
can activate the ECO option to allow the stove to automatically cycle on and off based on room
temperature data. *See Operation > Set ECO
Alternatively, you can install a simple, wired, remote thermostat. This can help maintain a more
accurate temperature range for the space.
NOTE: Activating the ECO function, or installing a remote thermostat will activate the electronic igniter
much more frequently, causing more electricity to be used, and wearing the igniter out much faster.
