Natural gas BTU vs propane BTU and pressure gauge resolution

[day]

Well, In the prepurchase I confirmed that the NG and Propane stoves can easily be swapped back and forth with a simple fitment. However, on reading more I stumbled on this site http://www.wardburner.com/gaspressure.html

Now I have some concern about the ability of the burners to keep up at such lower btu. Anyone know if there is a potential problem? I will know in a few weeks I suppose, but will have to have my dad help me run the NG line and set everything up, so it would be good to know in advance if it was a likely a no-go! 

Also, he said that the pressure gauge is 0-10kpa. But even propane operates at 11-14 inch of water, which I THINK is 2.7-3.4 kpa, when combined with margin of error of the gauge it seems like it really lacks resolution doesnt it? Even more so then on natural gas working on some 1.7kpa max.

You are right that that is not very good resolution.
Some of us have changed the gauge to a Dwyer with a 3.75kPa maximum.
A search (or searches) will turn up details and pictures etc.

I've also read up on this subject, and the larger sized jets compensate for the lower energy value of NG. Mill City has sold a number of 1K's hooked up to the home gas line without issue. They do recommend a higher pressure, something like 9-12 WC which give you more range. Apparently the atmospheric burners on the 6-8 WC suffice according to owners.

One option if the IR stove is insufficient would be to replace it with a NG Cajun Cooker.

My situation on the 14th floor is either NG or Butane.

Well bad news. According to mr li 1.7kpa or 7inch will not be enough. I will try it out with a short line to see what happens I think. Mill city said they need 7inch for their line but they may have more jets to accommodate it. Hopefully Mr li is just used to using it with propane? But he probably knows 

UPDATE coming:

Now, I naturally defer to Mr. Li, but realize that we all have unique experiences and skill sets, so it is possible that it will work in my circumstance. It is also possible that language prevented effective communication. Thus, I will attempt to hook it up and report back.

Promising information below:


http://www.lawsupply.net/tech_data/gas_jet_orifice.htm

   IR Stove LPG Orifice size is .75mm=.0295inch
                         Resulting in  5,950BTU/Hr at 11"WC

   IR Stove NG Orifice size is 1mm=.0394inch
                         Resulting in 5,400 BTU/Hr* at 7"WC
                                              *closer to 5,525

I have confirmed this information on a variety of sites. Given that most people seem to rarely go beyond 7" WC on propane it seems like there should be plenty of juice. Here's hoping!
