I lurk around the site more than post, but wanted to share an experience I had last night to hopefully understand why it happened. Around 3PM, I started a fire and it was going just fine. The kids and I went outside around 5PM to go sledding. While in the back yard, I look toward the front yard and notice a dark brown smoke laying close to the ground. I walked down the driveway where I could see the front of our house and noticed that the dark brown smoke was coming from our chimney. I only saw smoke and no flames. I quickly go inside and open the stove door, and the same color smoke was spilling into the house. All the while, I heard no sounds that I have read here that would indicate a chimney fire (roaring sounds, crackling sounds).

The damper was only half closed and I have been using this stove since October. Once I removed a few splits of wood and threw into the snow, I used wood ashes and start shoveling into the stove to smother the flames. I closed off the damper most of the way and went back outside. The brown smoke cleared and it turned back to a white/grey color, but I saw black soot on the roof near the chimney since the roof was covered in snow. I have burned less than half a cord since October, and the wood is seasoned pine and poplar. Prior to this when I go outside to get a few pieces of wood, I walk around the house, and typically see no smoke just heat waves. I would only see white smoke when first starting up.

After the stove was cold, I removed all the pipes and I saw white ash but nothing was plugged up. Coming off the stove was a 90 elbow into 2' straight stove pipe, then into a SS Tee fitting. I was not able to get the 5.5" SS uninsulated liner down the chimney during the install, so I cut off 6' and placed to the first terra cotta flue tile (direct connect) going to 7"x11" OD flue. I have since removed the block off plate and installed the original damper until I can get on the roof to look down the chimney.

From your experience, is this wet wood from weather conditions or early stage chimney fire? I swept the flue last April and only the powder soot was on the terra cotta. Prior to this, we used the open fireplace as ambiance. I believe this was my last wood fire as my OCD would always have me messing with the damper, checking the exhaust, sorting wood by moisture reading. I already have NG plumbed into fireplace and may work with fireplace store this coming summer for NG install. Easier to flip switch... until the power goes out.
 
Sounds like a chimney fire to me. And with a direct connect that could be dangerous. I would strongly recommend having it inspected by a pro and have it installed properly before continuing.
