Do you know what a clinker is? If you own a corn stove, you do! A clinker is a condition of fuel bonding together during the burning process. If your firepot is filling up quickly and you have overflowing clinkers, it’s likely that one of a few things is happening.
First, the most common reason for excessive clinkering would be the quality of the fuel, installation errors or maintenance. If the firepot is overflowing check your venting system, make sure that you have fresh air hooked to the appliance, check your home for negative pressure and clean your firepot out more frequently.
Then, if the firepot continues to overflow after just a couple hours it probably is fuel quality related. Check your fuel and if it is bad, replace with a quality fuel source. If the fuel is good, then check the firepot for proper fit, make sure the venting is clean and there are no problems with the draft blower system. Check all cleanout ports to make sure that the heat exchangers are not plugged.
There are complete maintenance, installation guidelines, and troubleshooting in your operations manual.
