Tankless hot water heater related questions

I currently own a tankless HWH which I am replacing soon. I have a few questions related to the new unit.

1. My municipality provides 7 CW natural gas pressure for my residential line. If I buy a tankless HWH that is rated for 8 CW, will it run?

2. How often do I REALLY need to descale the tankless HWH with white vinegar? I have a 2-person household.

3. For how long do I run the descaling process? What will happen if I run the descaling process longer?
