Secondary burn on Kozyheat z42

[Chris611]

I have a kozyheat z42. I see the secondary burn holes in the back of the fireplace. It's not a tube, but more like an angle that has holes in it with the faces of the angles at 45 degrees welded to the back wall just below the bricks in the top of the fireplace. What is the path of the air in the seondary burn process? From what I have searched here, hot air should come out of there and help burn the gasses? I haven't ever seen air come out of there. An I not burning hot enough?

Thanks
Chris

Chris, your not burning hot enough. Once you get the fireplace going good shut the air down and you should see the flames coming out of the tubes and rolling towards the glass. The first time I saw this it scared me a little. Lasts for a little while then dies down. I hope this helps.
