Apox how full or what level do you try to keep the burn pot with pellets..?
Your stove is the ussc 6041 correct? On setting 1 there is barely a hand full of pellets in pot on setting 9 might be a little less than quarter full. Has always amazed me that such a small fire heats my whole house. Toward the ended of 7 days you will start to see more ash in the pot and it will look fuller. That means it is time to clean the stove.
Your stove does not dump the pot like rona's. You have to pull the damper out to drop the ash under the burn pot. I usually do this each time I fill the hopper.
Yes my stove ussc 6039 runs 24/7, only shut down 20 minutes every Sunday for cleaning.
