Menards recently switched pellets to Indeck. These are the worst pellets Ive run yet. I have a Pelpro pp130. The Indeck pellets left a hard, flaky soot in my stove and a lot of unburned pellets. The Dejnos from Kenosha, WI have been top notch. Dejnos leave very little soot but still leave a good amount on the glass. The rest of the chamber is pretty clean. Attached is a pic of what was left over after running Indeck.
