Yes. Pressure loss over length is real. Suggest you talk to the manufacturer before ignoring their requirements.

This one does not apply but if you search online you should be able to find a calculator for your size piping.
LPG friction/pressure loss calculator.

Well, assuming I'll be using about 2.5 gallons every two or three months on a 16 foot run, that table seems to leave me well below problem level.
Thanks for the info.

Re: Propane line
 
I have seen several references online stating a 1.5m recommended maximum length for a flexible hose connection to a hard feedline, in order to accommodate a gimballed installation. It seems this might be standard practice in some areas, but is not the recommendation of the ABYC. Perhaps this is the reason your documentation reads as it does?

No, ABYC A-1, Marine Liquified Petroleum (LPG) Gas Systems makes no reference to any length whatsoever, whether pipe, tube or hose are used.

Capta, I can't upload pdf's to this site but if you send an email to [email protected] I will respond with the ABYC LPG Standards.

You can save a PDF as a JPEG... at least in Bullzip which is a great alternative to Adobe who changed their financial model to a subscription. Bullzip is a single purchase. I switched and love it. Interface is intuitive and easy to pick up. basic version is free! Upgrade is not expensive.

Thanks but I don't want any more software.

I tried saving a pdf as a jpeg (didn't know that could be done). It does work but I don't have the patience to upload 34 pages at one photo per page.

You are only storing the propane in liquid form. When you use it on your appliances you are drawing vapor off the top of the tank. The regulator reduces that gas pressure to 11" wc, or about 0.4psi. Such low pressure is very sensitive to restriction and pressure drop. At the burner the appliance relies on gas velocity coming through the burner orifice to draw air in to mix with the gas. If pressure and flow are reduced at the burner it may not mix enough oxygen, and you end up with incomplete combustion, which will manifest as yellowish flame, and sooting on your pots. Incomplete combustion also produces carbon monoxide, which, of course, is not a good thing in an enclosed space.

Gas is not something to be trifled with. If you are not sure, consult a gas fitter.

Re: Propane line
 
As noted above the pressure drop along a hose depends on the length and number of bends etc. in the hose. Another important factor is the inside diameter of the hose. Using a larger diameter hose will result in less pressure drop. A larger diameter hose that ends in a fitting that will attach directly to your stove might solve any pressure drop problem, should one occur. The trick might be finding one.
