Is there any tips on how I can keep the pellets in the hopper flowing easy and freely in to the auger. I have notice that my fire will die out because the pellets in the hopper do not make it to the auger. I find myself having to push the pellet in positioin or sometimes the pellet gets suck and I have to stick my hands through the pellets to reach the bottom of the hopper to free up the pellets. Any good tips on how to resolve this or must I babysit my stove?
