The combustion readings on the particular piece of equipment that you are working on will give you this information.
There are a lot of furnaces set to operate at 3.5" that are doing a great job.
The problem is 3.5" of pressure assumes a perfectly sized orifice and a certain parameters for the fuel.
If those parameters are met you're good.

Pot this is kettle you're black.
Before you start calling someone a troll you might want to go back to the business forum and delete all those hand grenade threads you've started.
Your last statement is correct except it's done by a different method than adjusting gas pressure.
Most water heater gas valves don't have pressure adjustments on them.

http://www.andersonforrester.com/ and get all the orifice charts you want. They are a good source for that type of information.
Watch trusting the combustion efficiency number on a combustion analyzer.
Unless the fuel parameters that are programmed into the analyzer are identical to the fuel you're using the efficiency calculations will be off.

I know we all like to think we are smarter than the next guy but stop getting out of control. You show me proof on your so called huge savings per customer and maybe I will believe you. A system will not work properly with crappy ass duct work too but most of the time that is ignored. You think you have some sort of magic bullet by with a factory set up furnace? I do not. If this was truly an issue perhaps we should petition the manufacturers to send us a full set of orifices with each and every furnace.I will believe that the government is broke when the welfare checks start bouncing!!

Don't know where the idea that there is some magic bullet came from in my post or any post I make. It sure would be nice if it was that simple unfortunately it's not.
Anyone that's ever been to one of our classes knows there is more to this than what we discuss in an open forum, ductwork is one of those things we are really big on correcting too. There is a huge amount of opportunity out there for correcting messed up stuff.
This definitely doesn't have anything to do with who is smarter than who. Not sure where that came from.
This is about helping each other to learn there is more to this than meets the eye and helping to open those eyes to realize the things that are going on in the field.
Read back to the front of this thread and you will see Chuck asked a simple question and was raked over the coals for it. That is what got out of control in this thread.

Actually chuck started with the accusatory attitude first. And why such a question popped on this particular thread is beyond me. This was a simple wall of pride post. From those pictures he had no indication that it wasn't set up to his standards. He was just trying to start a pissing match. And he accomplished it.
It's all laughable to me. I just wanted to poke a hole in his theory. But then I am splitting hairs. I'm pretty sure he started that path.I will believe that the government is broke when the welfare checks start bouncing!!
