New customer has a GB142 with 6A code. Previous company replaced gas valve and venturi. If I put my hand over venturi, the unit will light. Hand off.....and no ignition. Gas pressures are all within range. Inlet is 11wg, and outlet is -.02wg. Gaskets and covers are all tight. Why is this thing blowing itself out? I can sit there with my hand on the venturi, get it to light and run....remove my hand and watch the flame lift right off burner plate and go out. Anybody seen this before?
