Problem
The stove failed to start a fire or displayed a Failure to Ignite alert.
Customers may also describe this issue as:
- Stove will not light
- Failed ignition
- Pellets not lighting
- Failure to Ignite message
- No fire
- Stove starts but no flame develops
Symptoms
One or more of the following may occur:
- Failure to Ignite message displayed
- Pellets accumulate in the burn pot
- No flame develops
- Ignition cycle ends without fire
- Stove shuts down after startup attempt
Clear the Alert
To clear the alert:
- Press and hold the On/Off button located at the upper left of the control panel.
- Hold for several seconds.
- Allow the stove to reset.
What Causes Failed Ignition?
Successful ignition depends on three systems operating together:
1. Exhaust Fan (Combustion Airflow)
The exhaust fan creates airflow through the combustion system.
The stove requires adequate airflow and vacuum pressure for ignition.
2. Auger Feed System
The auger delivers pellets into the burn pot.
Insufficient feed may prevent ignition.
Excessive feed may overload the burn pot.
3. Igniter
The igniter heats incoming air and lights the pellets.
A weak or delayed igniter may allow excessive pellets to accumulate before ignition occurs.

Step 1 – Verify Igniter Operation
A weak igniter is a common cause of failed ignition.
If the igniter heats too slowly:
- Pellets may overfill the burn pot
- Delayed ignition may occur
- Startup may fail

Step 2 – Verify Airflow
Restricted airflow may delay ignition.
Common airflow issues include:
- Dirty stove
- Exhaust blockage
- Vacuum leak
- Poor combustion airflow

Vacuum Pressure Test
Use Diagnosis Mode to test combustion airflow.
Enter Diagnosis Mode
- Press and hold the Enter button (Left Arrow) until Set Data appears.
- Go to:
#6 – Diagnosis
- Select combustion level:
H01–H05
- Press Enter twice until Exhaust is selected.
- Press the Up Arrow to activate the exhaust fan.
Paper Test Procedure
With:
- Front door closed
- Ash pan sealed
Take half a sheet of printer paper.
Hold it against the 2-inch combustion intake pipe behind the stove.
(Remove Outside Air Kit piping temporarily if installed.)
Expected result:
The exhaust system should create enough vacuum to hold the paper in place.
Interpreting Results
Paper holds normally
→ Airflow likely acceptable
Weak or no suction
→ Possible:
- Vacuum leak
- Exhaust blockage
- Restricted venting
Additional test:
Open the cleanout tee cap and repeat.
If suction returns:
The restriction is likely inside the vent system above the tee.
Step 3 – Verify Burn Pot Condition
The ignition sequence assumes:
- Empty burn pot
- Primed auger
- Full hopper
Remove:
- Leftover pellets
- Ash
- Residue
Starting with fuel already in the burn pot may cause:
- Backfire startup
- “Bang-to-life” ignition
- Excess fuel accumulation
Step 4 – Verify Hopper Level
Low hopper level may reduce pellet density near the auger inlet.
If hopper level falls below approximately ¼ full, intermittent feeding may occur.
Many ignition issues resolve by:
- Filling hopper completely
- Restarting ignition cycle

Important Notes
Failed ignition is commonly caused by:
- Airflow restriction
- Weak igniter
- Feed interruption
- Dirty burn pot
- Low hopper level
Always verify airflow, feed, and igniter operation before replacing parts.
Escalate To Support If
Contact support if:
- Igniter tests good but ignition still fails
- Vacuum pressure remains weak
- Feed system appears normal
- Failed ignition repeats after cleaning
- Backfire startup events continue
