I wonder what you're trying to do? You could always contact the manufacturer for good info. I have 2 of these burners in my rig, and I thought the stock 10 PSI reg wouldn't be enough to supply 2 burners, so I bought a 20 PSI reg. The burners kept blowing out, etc....which is a dangerous thing if you turn your back for a few minutes.
I went back to the 10 PSI reg, and both burners can rip at full blast with the proper mixture of fuel and air. These burners are quite powerful; anything more and you'll be sending flames up the sides of your vessel and wasting fuel.
Why the different hose?
