I need some help figuring out my stove's drafting problem. Have had this stove for 2 years and it has worked fine, but the last few weeks has stopped drafting properly. I have already cleaned the chimney, the stove, kindling and wood is seasoned and dry, done everything I can think of and still the stove won't burn properly.
It seems the air intakes are not functioning. Have tried to make sure they are clear by removing bricks, shop vac'd the stove and outlets, used a long brush etc. Done every trouble shooting method I am aware of. It seems perhaps the air tubes inside the stove are blocked but there is no way to get to them. I even used a compressor to try to blow them out. Flu wide open but as soon as I shut the door the fire snuffs out.
My stove is a Hampton cast iron H300 and is only about 2 years old. Any suggestions?
