Calibrate your stove to light on the first click
A complaint I see a lot about this stove is that the piezo auto ignitor is unreliable or stops working. I have found that the performance of the auto ignitor is dependent upon the distance between and orientation of the sparking prong relative to the burner assembly.
If you have to click the piezo many times in order for the stove to light, you may simply need to bend the sparking prong with a pair of needlenose pliers. The stove will produce the best results when
1) The prong is about 3mm from the burner assembly. (See "Distance" photo)
2) The prong is centered over the screen instead of the gate. (See "Alignment" photo
I hope this has been a help.
