What burner should I use with my new brew stand? What burner works with low pressure propane? What is the difference between low pressure and high pressure propane? These are all questions faced when building a brew stand or sculpture. They can also be difficult questions to answer if you have not experienced the different burners. Let’s face it, we want to make the right choice up front because brewing equipment can become expensive. This article discusses low pressure propane regulators and low pressure regulators.

Over the last month I have had the chance to fine tune my current brewing sculpture and consider the options that I want on my new sculputure which is in the planning stage. I have come to the conclusion that low pressure propane is the right option for me.  During my research, I read several people discussing what regulator to use with certain types of jet burners. I found numerous opinions on what works best. I read anything from a 0-30 psi adjustable high pressure regulator to a standard .5 psi regulator.

The most important information you can learn in this article is to know what type of burner you really have. If you followed the Brutus Ten design, you will notice that most people have installed a jet burner. They can be cheaper in price and work great for automation.  Most of these jet burners are, indeed, low pressure propane.

So. Let’s think about pressure for a moment. I had the general thought that I want this thing to burn like a jet engine. The more propane pressure, the quicker it will heat! After all, if I turn my garden hose on to wash down the house or driveway,  I want it to have as much pressure as possible so the stream is nice and steady. This seems reasonable to apply this to a propane burner, however it really is not correct.  This goes back to knowing what kind of burner you have. High or low pressure?

I initially constructed my system taking the advice from several threads from some of the more popular internet brewing forums. Over and over again I read that a 0-30 psi regulator would work great! Guess what? It did work, but not as well as it should have. You see, I installed a Honeywell gas valve to assist in automating my mash tun through temperature control.  If I had the 0-30 psi regulator throttled down, it would work (with fine tuning by way of the ball valve).

If I just would have taken the original advice from Lonnie Mac over at alenuts.com, I would have figured this out long ago. He has said several times that he runs his jet burners on a low pressure regulator(s) and has not had any issues. I installed a low pressure regulator in place of my adjustable 0-30 psi regulator. I purchased a Mr. Heater brand .5  psi 200,00 BTU low pressure regulator . I fired up my jet burners and noticed that I did not need to throttle back anything with the ball valve. The burner provided a perfect flame! In fact, I am able to run two burners at the same time off this regulator.  There are other low pressure regulator options available such as the two stage regulator, however that is not covered in the scope of this article. (The two-stage low pressure is a great option as well)

Below are a few different videos which showing the jet burner being used with a low pressure regulator. The propane valve and ball valve are completely open. This is a 23 tip jet burner rated at 175000 BTU. (.5psi Low Pressure Propane)

    Just purchased a 23-jet burner, similar to the one you show here in your small thumbnail picture.

    How can i tell whether it is intended for LG or NG ?

    I’ve heard there are specific orifice sizes (drill size) for each. I intend on building an outdoor wok cooker, and ran into this website, which has much info.

    It only has the large 1/2″ Female NPT and the array of jet nozzles

    Thanks in advance. Happy Brewing

    They come as NG and Propane. You will not need to make any modification if you order the appropriate ones from the beginning. Just give the vendor a call and see what they sold you.

    Hello gbrewer. I am brand new to this forum. To my obsolute surprise I found your video and test between the 2 burner styles which was a hughe help to me in decided to either stick with the Jet burners or switch back to a Banjo burner.

    I currently use 3 propane burners to heat 3 lobster cooking pots filled with a slat water mixture. Each pot has 30 gallons of water at air temp when we lite them each morning. For the past 4 years I have used a 20 jet cast iron burner. When I purchased them I was told they were 200,000 BTU’s. (I replaced high pressure 3 ring cast iron banjo style burners in hopes of getting a quicker boil and a faster recovery time once lobsters were dropped in the pot) I gained about 20-30 mins until the burners needed to be cleaned or reamed back out to get back to full efficiency as boil overs and other things would begin to clog the jets.

    I am confused between the 20 & 23 jet burners as it appears the 23 jet one’s are rated at 175,000 BTU’s and the 20″s are rated at 200,000 BTU’s. (It must have something to do with the orifice size. I use a #74 reamer to clean my burners so it you do the math 20 x #74 orifice)

    My question is where did you purchase your burners and do you really know if they put out 175,000 BTU? I had found prices from $44 to $144 but can not locate the $44 dollar place anymore.

    Happy brewing!!!

    I purchase my jet burners from topfoodservice.com. You may need to tighten some of the jets when they arrive on the burner but I have not had any problems with them.

    Thanks for posting this info.
    I am still debating not only between the Banjo and the Jet burner but if I go to the Jet burners should I get the 10 tip or the 23 tip. I have read that the 23 tips are a little hard to control the flame on the propane version. Some think that the 10 tip is more than sufficient.
    I wil be trying a HERMS set up where the heat exchanger is in the HLT so I need good flame control there so that I can regulate the temp easily.. The Boil kettle could be bigger I suppose.
    The Mash Tun is a cooler and I am using the HERMS heat exchanger so I don’t need a burner for the Mash Tun. What would give me the best flame control for the HLT/HERMS heat exchanger?

    Thanks for sharing your build information. It is very helpful to those of us attempting the dame.

    I have a Honeywell controller and will be using my BCS PID to control the burner for the HLT. However, in reviewing the Jet Burners from TopFoodService.com, they make no distinction of High or Low Pressure. Other sites show Low Pressure models for Jet Burners, but they are two to three times the cost. Does it matter with Jet Burners if they are ported for High or Low Pressure? (Propane)

    If you have your paperwork from your purchase, could you please share the exact the model that you purchased? After seeing your in action on the video, I would be happy to have the exact same burner you show.

    Thanks again for all of the valuable information. Cheers!

    If I were to do this again, I would select the burners in this link. http://bayouclassicdepot.com/618lp-10-jet-propane-jet-burner.htm
    They are the perfect size for home brewing. If you chose to order from Top Food Service, just order one that is for the appropriate fuel. If you are using propane, make sure you order the LP version. It will work with you Honeywell controller. When I build another sculpture, I will be using the burners in the link I provided with my gas valve.

    I’m not in any way affiliated with Bayouclassicdepot.com nor do I know how they rate as a company. The price seemed competitive and this is really the more appropriate burner.
