As with anything new and expensive (to me) I am probably way over-thinking this new insert. I do have a couple of questions that I need help with on operation and maintaining. 1. I do not know if this is even possible after looking at the diagram of the insert but I swear I smelled wood smoke from the blower outlet last night. Is it possible that smoke could be mixing with the blower circulated air? I also had semi-sore throat and congested this morning after burning all night last night. The insert did not smell the same as the "break-in" smell. 2. The glass is already browned up and cloudy. Tried to clean with good foaming glass cleaner No good. just smeared and didn't work. Any tips there? 3. How often do you clean out the ashes from the insert? Every four hours or four days? I seemed to have a lot of ash build up after 8 hours our so of fire. Damper kept mostly closed most of the time. Just not that cold here yet to need alot of heat. I really have no experience with a stove or insert just open fireplace fires.
