Thank you!
I replaced the burner ending with a 3/4 to 1 1/4 reducer, earlier it was a 1.9'' steel pipe. Is it looks better ?
Still, when the burner inside the forge I have this jumping on and off problem especially when the back of the forge is closed or half closed. I added another video about that.
Gas pressure is 0.5 bar (~7 psi)
Part sizes are in the drawing blew.
Thanks !!!
