I have built a three tier system and now I am going to plumb the gas lines. I bought 160K BTU burners that are 3/8" so I am going to use 3/8 copper tubing. The problem I am running into is if I can use a 1/4" supply into the manifold? Also what psi rating regulator should I get? I read somewhere people using 30 psi but I can't find any.... Any thoughts, recommendations would be VERY appreciated.

It sounds like you are going the high pressure route so the 1/4" inside hose that is used with the regulators should work well. The chances of having 2 burners at a high fire setting at the same time is usually small so one 10-30 psi regulator should do well on the rig. I fire 2 100K burners with a 3/8" Od gas supply at 10 psi and have no troubles, the burners are connected with 1/4" od SS tubing from the manifold.

Is it safe to assume that you are using propane and not natural gas?

copper and galvanized are not approved for lp or natural gas delivery. only black pipe, and special pet/pvcs/rubbers.

Copper is fine for gas. Both LP and NG. Even aluminum will work.

Copper is approved for propane, if your not in california (from what I read) but NOT for NG...

Unless your pulling a permit for your brewstand, I don't think it matters, it will all hold.

This is not true. Copper and brass tubing should not be used if the gas contains more than an average of 0.3 grains of hydrogen sulfide per 100 standard cubic feet of gas (0.7 milligrams per 100 liters). Check with your gas company for hydrogen sulfide content levels and your local building codes before using copper pipe.

Well, lets be realistic here. Applying the same logic that I applied when I decided to use 3/4" plain old reinforced goodyear rubber heater hose for my natural gas connection to my brewstand. This is not like a furnace, it will not be continuous duty. It will not see a ton of use when you compare it to a furnace or a how water heater. When I am using this, I will be watching it, I will be with it. So, if there will be a problem, I will be right there to address it.
