I'll dig and google around I guess :-)

The Crown Boiler Install manual ust says " refer to whatever number / chapter of the US gas code for pipe sizing" .....its very helpful they couldn't have just said ....you need whatever size ....or whatever gas pressure ....for this or that size boiler ?
both easy to measure :-) .......instead refer to a bunch of tables ,find which one applies to you first if you can .... I hate it when companies make it harder when not necessary ... :-)

It's not harder than necessary. Every installation is different, and the required pipe sizes will change depending on factors such as distance from the pressure reducing equipment, the meter, other appliances hooked up, how many fittings and what sort are in the way... and so on. The tables help the craftsperson installing the system to do it correctly, without having to resort to the head loss calculations which are otherwise necessary.

Boilers and such are not plug and play, and you can't treat them as if they were the latest digital widget. Doesn't work that way.

I might argue that Crown Boiler did it right. The code can change over time and location...why should their manual partially try to replicate the tables that may or may not apply to a given customer?

Although the laws of physics that dictate the pressure drop in a given configuration of gas piping do not.

everything should be plug and play make life easier

See we distribute gas inside residential houses at 7" water column pressure, it was designed for gas lighting, it is more like duct work than piping so you need large diameter pipe to distribute a high volume of gas without pressure drop.
