With the blowers off on this insert, I was doing smoke test on door for first time. When going around lower part of stove, inoticed there is some draw from underneath the stove where the blowers sit. No noticeable cracks in floor of firebox. I just read in manual that the air inlets for primary and secondary air are located toward the rear of the firebox. I'm figuring what I am seeing is the slight draw from those inlets, but for some reason figure that That would not show up on smoke test. Stove appears to be functioning as normal with dry wood. Any thought would be appreciated.
