I have a superior ssdvt3530cnm with glass front door. We recently replaced the pilot assembly, upon replacing the pilot the logs take about 30secs to lite and burn erratically. Before hand the logs would not light at all. With the doors off the logs lite and burn perfectly. When lighting the logs with door on if you crack open the glass door it will lite immediately. Im suspecting that the logs are not getting enough intake air. We have checked flue pipe for restrictions found none, the flue terminates about 2' above roof towards back of the roof not at the peak. Ive thought about adding onto the flue or moving towards the peak of the roof but wanted to get others onion first. I've read though the manuals and couldnt come up with nothing, also superior does not have a tech support line.
