Hello all, first time writer, long time listener. I appreciate all you knowledgeable folks helping a wood burning newbie like myself through big decisions. And as far as beauty is concerned, the Hampton was a great decision. We had it installed last week. I planned on having a full ss liner installed, but the installers said that the chimney flue was "bent" and they couldn't snake it down. As a result, I'm stuck with a direct connect to the flue (6 foot ss) with a blocker plate at the damper area. They said my flue was in very good shape (6"x8"), and my wife said it seemed like they give a valiant effort trying to get the full liner in. My question is, how far should a press the issue on the full liner? Is it worth a second opinion? I understand the cleanings are more difficult without it, but are there serious performance and/or safety concerns I should have?
