Just installed this stove and pipe. When looking down there is a smalll gap that you can see into the firebox. The pipe is seated all the way down, the gap is in a spot where there wasn't a screw hole so it didn't get sucked in tight by a screw. The stove has about 24 hours of burn time so far and haven't noticed any smoke coming from the gap at any point in time. Is this a problem or normal
