If I find unburned pellets in my ash pan, can I reuse them?

Never put any debris or pellets found in the ash pan back into your appliances hopper. This is to ensure your safety. Ash pan debris may contain embers, which could ignite the rest of the fuel in your hopper. Properly dispose of these pellets with the rest of the debris by emptying the ash pan into a metal container featuring a tight fitting lid. Keep this container away from any combustible materials at all times.
