FWIW 11 inch water column is normal

A week back they dropped the 120gal tank. Same rating as my RV 11”wc regulator and the one that came with the unit. Same as your link

Yes, exactly, pretty standard, just a larger volume than the standard camp stove regs. My camp stove reg got the water to luc warm at 1.6 gal / min flow. I do know of some natural gas residential/commercial on demand units that can use the 2 psi household pressure.

I’m talking out of hand cuz I have little experience in the field
However, I’m pretty sure regulated propane and natural gas are way less than .5 psi delivery. I’m thinking NG at .25 and propane 35psi. 2psi doesn’t ring any bells for anything I’ve run across.
