Lpg regulator question

This goes out to anyone who may have the knowledge in this area to help me out. Getting close to plumbing the propane lines for my food truck and was wondering, do I need one regulator to run my appliance or does each appliance require it's own regulator? I will be running a stove with ovens and a griddle, a fryer, a grill, a generator and a tankless water heater all on propane. I'm sure if I dug around long enough I could find the answer but I'm sure someone on the forum could explain it to me. Thank you in advance.

    You should review the needs of the appliances being used.    Generally, you only need to supply std pressure.  Then any low pressure appliance will have its own regulator to step-down the pressure.     If you use proper pipe size for the BTU supply needed, then there should no reason for 2 stage pressure/regulator system (ie: high pressure supply with step-down to normal pressure).

    Be sure to add up the BTU requirement of all the units. The primary regulator has to be rated for that load you need. I used an app- Rego.com. Plug in BTU requirements, length of pipes to units and it will show pipe size to use and show regulator models that will meet your needs. Worked well for us.

    Sorry I posted that wrong.... it's: http://www.regoproducts.com/
    go to products line. Also the phone/pad app is really handy for figuring your BTU to regulator needs.

    Here's another one. My grill has a regulator installed on the back which makes it stick out too far. My question is if I were to remove the regulator , add 30 inches of flex pipe and re install it on that pipe so it was in a different position so the grill will slide in closer to the wall, would that work?

    That should be OK.   Also, adding an elbow before the regulator should work.  Make sure the regulator is easily accessible.

    Someone has told me that the regulator had to be connected right at the back of the appliance which made little sense because it should regulate the same pressure for any length of pipe.

    Possibly,  check the installation manual for the grill for regulator requirements.    This was part of the reason for my suggestion of using/installing an elbow instead of 30" of pipe.     The extra pipe length might cause additional pressure drop at the low pressure setting.

    How do you actually select the correct primary regulator? What factors influence the selection and supply pipe size?
     
    In my other thread here I posted a diagram of what I thought is a rough propane system diagram, but I dont know if Im missing any parts to the system. I havent seen a complete system from one end to the other so the the diagram was a guess based on 'pieces' that Ive seen.

    We use the single stage regulator if we only run one appliance, and we use a dual stage regulator to run multiple appliances off of the same line. This is really question to direct your fire department.
