I have a Breckwell P24i inserted into a masonry fireplace with pellet pipe running to the top of the chimney. The unit has been working great. I bought it in fall 2008 and have burned almost 4 tons of pellets this winter. I recently noticed one oddity that I'm wondering about. On the bottom right underneath the front of the unit, I can see a small reflection of the flame where the stove sits on the masonry platform. I have to get down on the floor and the room must be dark to see it. It's barely noticable, but it is there -- a bit of flickering light -- just a pinprick -- coming from the fire which reflects onto the floor. I don't smell smoke in the room, and the stove appears to be working properly. Is this normal? I'm assuming that there must be a tiny hold in a weld someplace underneath, but I'm surprised that I don't smell smoke.
