heatilator direct vent
having a problem with the flame lifting off the thermopile and going out. works fine when the glass is off as soon as i put it on 20 seconds later it starts at the first openings in the burner,right by the pilot. thought air intake right away pulled everything apart looks clear, short vent 1- 90 5' total length
Your exhaust and fresh air are mixing somewhere. Recheck all of your connections.
