Can you tell me step-by-step how to perform combustion tests on a natural gas bouiler ?
Thank you for your help.

Huh?
Premix burners have two designs regarding gas inlet, positive or negative pressure gas valves, depending on placement of venter, both easily set up with a manometer for correct firing rates.
I understand that in Europe, for instance when installing a Viessmann for example they state set gas regulator for 21 bar, well here we don't always have the luxury of setting incoming gas pressure so that our mix is correct based on factory settings, thus we tune the gas valves for a proper install.
I suggest you stop believing what other people post or write on the internet and follow what US manufacturer's publish in their install manuals.
Regarding pre-mix negative pressure gas valves on the Weil McLain boilers,
You're referring to this?Yes you are correct in the warnings that a standard fluid manometer was not to be used, it suggests a U-Tube or digital, That warning is for idiots that don't understand.
Dig deeper and you will find the proper way of doing it.
Check gas valve outlet pressure
After following the start-up procedures of manual Section
VII, follow the procedures of Section VIIf to measure gas
valve outlet pressure and adjust if necessary.
Failure to check gas valve outlet pressure and adjust, if
necessary, could result in severe personal injury, death or substantial
property damage. Carefully follow the guidelines given in this manual.
Why do you challenge a US boiler guy on US boilers?
This is awkward, but...
