Running on air is just for fun
The unit came with 3 boxes of fuel pellets and a large burner setup for the back packing stove.
I will try to use the burner

It looks new or ma bee one use
No box or book

Assuming you have whistle with chain? That is M6x1 and Safety valve M6x0.75

Curious, why do you have to run on air?
