When I start a fire from cold I will see the cat temps rise from room temp to about 300*. I don't think you will really see anything past 300* because it is usually time to close the damper at this point. On reloads I will actually see the cat cool off more while I'm waiting for the fresh load to char some and establish good flue temps again. What model is your encore. My 2550 has the EPA holes behind the front legs. They deliver air into the ash pan.
