Recommended Regulator for Propane Powered Water Heater and Stove

Question

Question:

I am changing my Travel trailer propane water heater to a propane tankless water heater because they no longer make the water heater I need so I am changing all of the gas piping to support the new build with a 100lb propane tank, I will have a Rinnai v75i tankless water heater that needs Inlet Pressure: 11.0 inches W.C. and The gas input of the V75i is 180,000 BTU/HR I will also have a stove/oven connected that has the same 11.0 inches W.C. and the top burners are 5,200 BTU/HR and the oven is 7,200 BTU/HR. Do you have a propane gas regulator that can handle this system?

For your setup the MB Sturgis 2-Stage Propane Regulator # 108221 will work perfectly. Its 2-stage design will reduce the pressure to the needed 11" WC and it has a maximum flow capacity of 400,000 Btu, plenty for your application.

I have attached a short video review that you can check out as well.
