I have a blaze king King which I got used it has only been used maybe 3years when I started using it we had problems with draft and it smoking up the whole house. We have added about 12ft of triple wall stove pipe to fix that issue, however if we fill our stove full and let it get good and hot them turn it down to a 1 or 1.5 the stove will sometimes smoke out the back and the stove pipe will smoke or it will just put the fire out all together, the people at the fireplace center told us we have to keep it burning hot, if I do that I have to get up one to two times in the night to put more wood in the fire. I know I live where it is cold but it isn't always that cold I believe this spice is capable of way more. We have cleaned the catalyst a couple times. Not sure what else to do or what could be causing this stove to not run as efficiently as it is supposed to. Please help I'm going crazy and ready to get rid of this and go back to an old one that I know how to run! Thanks
