I have a P22 and it starts up fine, great flame but then after about 15 min I lose my flame. Auger is turning every 14 sec on high..not sure how often its supposed to turn on high. Sometimes though it will only drop a couple pellets, sometimes quite a few. Usually though it's on dropping 1 to 4 pellets. I assume this is why I loose my flame. There is not a clog in the chute. Have taken the panel off the auger and ran a hanger down it. Everything inside has been cleaned. Please help....why is it not dropping very many pellets and why am I loosing my flame? Thanks
