Type of propane regulator on AG system
What type of regulator does everyone use on their AG gas systems where one tank is used in a plumbed system to feed two or more burners?

Out system has two 50,000 BTU burners (King Kooker), one for the hot liquor tank and one for the boil tank. We've plumbed up copper pipe to the burners, and have a needle valve to control each burner.

We originally installed a turkey fryer propane gas regulator on the propane tank that contains a red low pressure control valve. The performance of the system has been erratic lately, with the gas flow from the regulator fluctuating.

Question: since we have needle valves on each of the burners and only use one at a time, can we use a standard propane grill regulator that doesn't contain the red low pressure control valve? I'm thinking that since we already have a needle valve to control the flow of gas to the individual burners, the turkey fryer gas regulator with the red low pressure control knob is not needed, and may account for problems with gas flow.

Thanks for the view and replies. :mug:

Sounds like a question for Hank Hill... :)

I use a standard 10 psi regulator from a turkey fryer. I have it plumbed with ball valves to each burner. It works great with 1 going or all 3.

Thanks, Lil' Sparky.

Does your regulator look like this:


Or like this:

Neither exactly, but I guess it looks more like this one.


You can see it a little in this pic.

Yup, thanks. You've got a high pressure regulator with a variable flow control knob.

We started having problems with ours during last Friday's brew session. The gas flow through the system began fluctuating, and fell off dramatically when the variable flow knob on the regulator was turned the full "on" position. We also have needle valves in line with our two burners.

Although the regulator is just a couple of months old and has only been used for 4-5 brew sessions, the regulator itself may be defective. It worked great the first couple of times out, but has started to "act up".

Also found information on the bypass safety feature of propane regulators on this page:


We'll try to "reset" the regulator system to see if that's the problem. If not, we'll replace it.

Lil' Sparky 07-02-2007 02:41 PM

Good luck. At least it's an inexpensive part if that's what needs to be replaced.

I'm no Hank Hill but I'd think 10 PSI would not be enough for 2 each 50,000 BTU burners. Nowdays most 50,000 BTU units come standard with 10 PSI regs.

I'd go for a 20 PSI or an adjustable 30 PSI.

Just looking at the picture of Lil Sparky's reg it looks a lot like an adjustable regulator rather than a fixed to me. As a rule, usually an adjustable reg has a knob on top of the regulator (just like the picture lil sparky posted) a fixed PSI reg will not have that knob on top.

That being said I'm sure there's an exception to every rule.

Lil' Sparky 07-02-2007 02:56 PM

Mine is adjustable, 0-10 psi. If mine ever craps out, I'll definately go for a 0-30 psi reg.

drayman86 07-02-2007 03:28 PM

Thanks for the discussion, guys.

Decided to go with a 0-30 adjustable PSI regulator; ordered the first one on this page.


I'm fairly certain that our regulator is defective. Shouldn't make any difference that we've got needle valves to control our burners and an adjustable regulator. Was thinking that there was a pressure "confusion" on the part of the regulator due to the adjustable valve at the regulator AND the needle valves, but I don't think this is the case. Fluctuating gas flow likely due to diaphragm problems in the regulator.
