Blender 2.73 Cycles fire render problem

Hey! Hope this is the right thread for this.
I have an issue with rendering fire in blender cycles engine. The thing is that when i preview it in the rendered viewport it looks ok and it illuminates other objects(img 1), but when i render it the fire isn’t there but it still illuminates other objects(img 2). I’m rendering on CPU.
Any ideas?
