Why is there buildup in my firepot?

It is normal for there to be a small amount of buildup on your firepot as a result of everyday use—there is nothing wrong with your stove. This buildup should be removed daily as part of routine maintenance. Fuel quality can affect the amount and strength of buildup on your firepot. For this reason, if you’re noticing abnormal buildup consider switching the brand of fuel you are using.
