Hey guys, been awhile since I posted here but I am having major problems. It seems that my installer didn't do a good job and did not seal the top of the chimney well. All the rains this Fall ended up down my chimney. In trying to start a fire I am not getting any air into the box. Maybe the vents are clogged with rain/crud? Smoke is going up the chimney somewhat but when I open the door smoke spills out. Any idea where these damper vents are? Any ideas or help appreciated.
