Air and gas mix at the intake shutters which are found at the ends of the burner feed tubes. The flow of gas from the orifice draws in air through the open shutters via the venturi effect. You adjust the mixture by opening and closing the shutters.
Ok. Thanks for your info. Just a note for others I did call and company rep told me that they can't sell the parts to the RCS owners but it will work if you can get a hold of the parts
This video demonstrates the upgrade of an 18K burner. The 18K and 22K burners are the same part. Identical. That's why I suggested that you learn something about the range you are talking about. Now, one may go through life cowed by manufacturers' marketing schemes and plans to extract $2500 dollars more from people for nothing other than a $3 Garland M8 small orifice, or one may not.
I'm very late to the party here, but from what I can gather, because you can't purchase burner assemblies larger than the 15k burner, they're extracting a very high premium for a rather small upgrade in power. I would bet that the 15k burner head could be modified to deliver 22k BTU's by drilling the head and change the valve as you did (I would never try to modify this type of valve). With a little effort using the right tools and a commercially sourced valve you spend less than $50 to save $1,000. I would do the same thing if I were them so no ill feelings, but, the premium they're wanting is beyond what I'm prepared to pay.
The manufacturer is full of hot gas. Skilled owners have been modifying these ranges for years, upgrading ignitors, flame sensor modules, and orifices and burners. This particular manufacturer took three or more years to design a reliable oven door hinge mechanism. The RNB is an RCS, minus the convection fan, in ranges of my particular vintage. Modern RCS ranges omit the 18K burner, but everything else is identical. There is no issue with "the regulator." What there is is a desire for more $.
This "jetting" at the burner can result in extinguishment of the flame, incomplete combustion, and presents a safety hazard. Burners must be matched with orifices. Bluestar asks for a serial number when you order parts from them, that's how they keep control of who gets them. They insist that their parts distributors get a serial number for every big burner they sell. They charge an extra $3,000 for the RNB and are intent on protecting that revenue stream at all costs.
I don't have access to burners or I would sell them myself. An enterprising person would probably make a lot of money if they were in possession of a foundry and could cast the larger burners as replacement parts. I need to make something clear, though. The burners and orifices go together. You MUST have more gas ports, ie, bigger burner, in order to safely use a larger orifice. A bigger orifice alone in too small a burner will result in incomplete combustion and jetting (continued next)
Hi and thanks for posting this UA-cam Video. I have a 2011 BlueStar RCS 30" and absolutely love it. I however would like to upgrade one burner, but may not want to go all the way to 22k. Being that I currently have 15k burners. Can I go to the 18k by installing the burner assembly,adjusting the shutter, and leave the orifice size the stock 15k? Thanks again!
You could simply drill the orifice out with the correct size drill bit, I believe that you said it was a number 47. This is how gas input is adjusted in a furnace, etc.
Hi again. Thanks for the reply. It's a shame that Bluestar won't sell the burner to the RCS owners, even though older RCS stoves had the 18K burners from the factory. I wonder how much they check on that, Would they not even sell to the dealer without the RNB serial number? Just to clarify if you would. With my current 15K setup- Is it just the burner thats required, and not the orifice, if one just wanted to upgrade to 18k only. Thanks again. I take it you're a cook that likes Jimi Hendrix?
I understand what you're saying about going from 18K-22K requiring the burner port assembly and orifice change together and from 48 to 47 for proper combustion to get to 22K. I assume the current RCS with 15K burners uses a orifice size smaller than 48? as I only want to get to 18K. I settled on the RCS because it was a lot less $ and besides the extra BTU's. The louvered kick panel, bull nose top and roller bearings it was not enough justification for the extra $. Thanks again for all your help
Do you have any advice on how to get BlueStar to sell a charbroiler accessory, I have the RCS 36 15K Burners BlueStar is difficult to work with to order parts . They only sell charbroiler on Platinum model
Scott, I know this vid is 7 years old, but is there a way to get the 18k burners anywhere? guaranteedparts won't sell the burners without a RNB model and serial number. Thanks for your video.
Hi, Thanks for the info. I have one question. If i buy the LP to Nat Gas conversion kit (for the RNB-part CKRNB30NAT) will that contain the oriface I need for this upgrade assuming I have the right burner head? Awesome post btw.
No, that package will just be the orifices. It will not include the burner. You will need somebody with an RNB to order a burner for you. Sorry, I cannot help in that department. Bluestar will not sell you a 22k burner without you first providing the serial number of an RNB range. This video was made using the OLD RCS models like mine that included the single large burner. The new RCS models only feature the 15K burners. Sorry!
Robert, I hope you were able to get your question answered. The 15k burner is dimensionally smaller, so you need to order the 18k burner. After that, then go with the larger orifices to get to 22k. It looks like Bluestar is getting about $100 each for the 18k burners, and then to re-jet to the 47ga nozzles on the 5 burners (assuming an RCS 36") will cost you about another $50. Air adjustment is critical in order to get rid of the yellow flames.
Scott I will buy a new RCS with 15K burners ...I would like to upgrade to 22K burners at least two. Could you walk me though this ...also what parts I need to buy. Thanks Joseph
Your right, Knowledge is power. Why are you asking me to research a RNB range? Your video is talking about the RCS serious. On the RCS serious, the manufacture said they was having problems with converting the burners with higher BTU's. They said they was blowing out the regulators. So it's not recommended. I personally don't understand why the regulator was being blown out but they would not let me talk to an engineer. On the RNB serious, the burner and the orifice would need to change.
Great video, super handy. I've heard some hubub around the "manifold being overloaded" from the Gardenweb forums from about 3 years ago. That sounds like a load of crap to me, but was wondering (if you're still on UA-cam) if you'd run into any issues doing this upgrade with just the gasket, orifice, and burner head.
Great video-this video is great as I’m thinking of “hacking” an RCS” 30”. Are you supplying or have you found a supplier for the47k orifice/55k? for propane. Talked to the salesman at local store today and confirmed that they wouldn’t sell that upgrade unless you have the RNB model. Pardon me if I haven’t seen an updated video or gardenweb post. Their really isn’t another stove that compares but seems silly that you can’t upgrade through manufacturer. Thanks for doing this video. Let me know if you can.
You can get the burners elsewhere. Just do a search. The 18k burner part number is 18k Burner Head - 729801. Check guaranteedparts dot com. They require a model and serial number to order, but that should be simple enough to spoof. Bluestar does not want people doing this because in their nearsighted thinking, they think that it will prevent future sales. Well guess what?! I can't afford an RNB or BPS series range anyway, so their thinking is stupid. Hot-rod what you've got and keep using it!
Anyone have a RNB serial# they could pass on to me so I can get a 18/22k burner and orifice for an RCS? Looking to go from 15k RCS to at least 1 18/22k BTU burner. Thanks
Travis D Heya, ever get this done? I'm sure I could dig up an RNB serial # to do the conversion, but was wondering if there was any physical limitation in doing it.
ghostreverie I did. I was able to use the RNB serial to get the 18/22k burner piece from one of BlueStars parts dealers (online) (but they wont sell the gas orifice even with the serial number), so I ordered that from a restaurant supply website, as it is a common piece (#47 Garland orifice). Install is just as easy as this video shows. Love the 22k burner
Travis D That's rad actually. So, what, $200ish to upgrade from the 15k to the 22k? The price diff is pretty staggering. We're able to get a 36" RCS for $3700, but the 36" RNB is ~$6200. I guess my only other concern was the pipe/air shutter, but that seems to be adjustable. Edit: and the "manifold" or whatever feeds gas to all 6 (or 4) burners being overwhelmed. From what I can tell, though, the feeder to all burners is the same between RCS and RNB models.
ghostreverie Yes, about $200ish for the Burner (BS-729801), and then All-Points #47 orifice (AP261107) from webstaurantstore.com for a couple more bucks. Totally worth it for wok'ing alone. And yes on the manifold. If you look at the BlueStar parts list, the RCS manifold is the same, even for RNB models that have multiple 22k burners and 18k burners.
Travis D Awesome. Thanks sir. This makes my Range choice a lot easier. Did you end up having to swap the gasket on the new burner, or just re-apply? (Appreciate the feedback, btw).
Mojavean, Thank you for the nice video. As a prospective RCS buyer wanting to upgrade one burner to 18k, this thread was very useful, more so than the many posted on GW. It looks like there is no simple way to upgrade a new RCS to 18k as the company would not sell the kit except as part of the RNB. Shameful! BTW, what did you do to get banned from GW? I'm genuinely curious to understand why GW would prefer barring someone who added very useful and informative opinions from posting.
No. This upgrade is to take an 18K burner to 22k. You MUST have the 18K or 22K burner head, OR, you must drill some more holes in either the 8K or 15K burner to get more gas ports. You need the bigger array of holes for the fire to come out, speaking as simply as I can. The 18/22k burner has the large array of ports. If you do not have the large supply of holes in the burner head, you will just get gas "jetting" out of the burner. Get a 22k burner, or drill out your existing burner head.
My name is Tony Casillas and I am a gas engineer. I design and test cooking equipment. The first thing that I want to tell you is NEVER change the orifice on any gas appliance unless the manufacture tells you that it's ok. And always use the manufactures parts. The difference between the #47 drill bit (.078) and the #48 drill bit (.076) is .002 of an inch. A wobbly hand or drill bit can make a big difference in the hole size.
Basically there is nothing you can do without first getting the larger burner, and there lies the problem. Bluestar will not sell them to RCS owners. Period. You MUST supply Bluestar with an RNB serial number in order to get the larger burner. You MUST have the increased number of gas ports in the larger burner to install the bigger orifice. It won't work, otherwise.
Have you ever tested a unit for CO? I have, and I can assure you. Higher BTU's will increase CO. You can offset it by increasing port height or changing to a burner with more ports.
By changing the orifice to a bigger size hole, you will get a bigger flame. The problem is that the flame will get closer to the pots or pans. This will create more carbon monoxide (CO). Carbon monoxide in high dosage can kill you. Orifice sizes are determined by the type of gas you are using and the elevation of your home. Only the manufacture can tell you if the appliance can be safely ran at a higher BTU's per hour.
Higher heat will make the appliance hotter which can change your installation clearances to combustible construction. Now let's talk about liability. If you have a fire in your house and the investigator determines that it was caused by the appliance that you modified, they can deny your claim. Putting a video like this on the internet is stupid and irresponsible. Give a man a little knowledge and he can be dangerous.
Just a home cook, lovin' his range (best range I ever cooked on, bar none -- it's a beast!) and yes, big fan of Hendrix.
Air and gas mix at the intake shutters which are found at the ends of the burner feed tubes. The flow of gas from the orifice draws in air through the open shutters via the venturi effect. You adjust the mixture by opening and closing the shutters.

Natural Gas only. Those size orifices are too big for Propane.
Agree. You are better off simply buying the right orifice from any of several restaurant supply houses selling Garland range orifices.
I understand what you're saying about going from 18K-22K requiring the burner port assembly and orifice change together and from 48 to 47 for proper combustion to get to 22K.

where do i get the burners and orifices ??
Does anyone know the orifice size for the new 25k burner ,thks
You know this guy knew what he was doing when you saw the Beck's on the counter.....
in bluestar ranges, where is located the air/gas mixer?
Do you have any advice on how to get BlueStar to sell a charbroiler accessory, I have the RCS 36 15K Burners
BlueStar is difficult to work with to order parts . They only sell charbroiler on Platinum model
I kind of assuming that by getting that package it will get me the required parts to do the same upgrade.
Any guidance on how much force to tighten the orifice with?
Yeah, just snug. It is fine thread brass and an orifice, not designed to hold pressure. Pull it snug and stop. Don't crank it, no need.
Scott, I know this vid is 7 years old, but is there a way to get the 18k burners anywhere? guaranteedparts won't sell the burners without a RNB model and serial number. Thanks for your video.

Before I answer, are you using LP or Natural Gas on your stove, Shen?
CO is the same produced by the RNB, the configurations are identical.
I have an RCS 30Bl;ue star L P gas range an would like to change the 15 k burners to 18k or 22k L P
