I would not recommend that burner.
These burners are great when you have the valve wide open, but for low heat they can burn dirty yellow, with soot.
There are a few threads on here on these type of burners.
NG is a low pressure gas, and for a normal house you do not have the pressure to run that burner correctly. It will burn dirty yellow, cool, and put soot all over your kettles. What people end up doing is plugging 13 of the 23 jets in that model, and then they work correctly. Also it is important that you pick the right pattern of jets to keep.
Bobby_M has the best video and instruction on this.
I went the same route as you are going, more must be better, so I bought the 32 jet version. Now I have that down to just 6 jets, and that is producing the best results for high heat and low heat (rolling boil).
I just ordered three of these.
10 Jet Natural Gas Jet Burner
Dont think that these type of burners are bad, a lot of people use them, and I will continue to use them. They are the easiest to mount, just connect them to your 1/2 black pipe, and add a standard NG gas valve, no regulator needed.
Here is a great picture of the 10 jets in action.
This is what my current burner can do:
70 degrees to 150 degrees in 15 minutes
150 degrees to rolling boil in 30 minutes.
