Problem with pinhole gap in bottom right underneath Breckwell P24i

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.

I did not install this stove, but the manual shows the leveling bolts at the back of the unit, on the left and right. These holes appear closer to the front. I did not mention in my previous post, but there *are* two of them, so they obviously exist for a reason. There is one hole on the left and one on the right. Both are directly under the side glass windows near the front/side corners of the unit. They don't appear to be located in the same place as the location show in the manual for the leveling bolts.

Many thanks. I see the legs show in figure 18 of the manual. That's it.
