Is hard buildup in my firepot a problem?
If you have cleaned out your firepot and you find hard buildup remaining, you most likely have nothing to worry about. This buildup is caused by impurities in your fuel, which means that it is not an issue with the operation of your appliance. Be sure to scrape any hard buildup off your firepot daily as you clean it. To avoid this issue, using a different brand of fuel may be necessary.
