How to hotrod a Bluestar RCS model
For those of you with the older RCS model Bluestar ranges with the single 18k btu burner in the right front hob, you can upgrade that burner to a 22K Ultranova by simply replacing the burner orifice (sometimes referred to as a spud.) with one with a tiny bit larger hole. The 18k Supernova burner has a 48 gauge drill size orifice and the Ultranova 22k uses one with a 47 gauge hole. You can find the equivalent drill sizes in both metric and English via Internet search engine.
The newest models of RCS ranges do not have the 18K burner. In that case, owners will have to order an upgrade kit from Bluestar. The parts are as follows:
Burner #729801 $77.57
Gasket #734301 $3.52
Orifice #709548 ~$11.00 (it's ten and change and I can't remember the change!) Note, this is the 18K - 48 gauge orifice. If you want the 22 then tell them to send you that instead.
NOTE: THIS ORIFICE IS FOR NATURAL GAS ONLY! Do not order this orifice if you use LP. The orifice will be a different size.
The videos don't cover replacing the orifice, but it is easy. The burner feed tubes fit right over the orifices, so they are fairly easy to see if you peek in from the top looking toward the front of the machine.
You need a 7/16" deep well socket and about a 6" extension.
Slide the socket over the orifice until it is captured. Attach your ratchet and unscrew it. Note how hard it was to remove the old orifice. (not hard)
Next, put the new orifice in the socket and using only your fingers and the extension, finger tighten the new orifice on the gas nipple. Only after the threads are started correctly should you use the ratchet to finish tightening the new orifice. Don't over-torque. The orifice is brass and you do not want it deformed or or the threads damaged in any way.
With that burner head you will be able have either an 18 or 22kbtu burner, depending on the orifice.
If you choose the 47 gauge example you will be doing the Ultranova, Baby.
By the way, I would like to add that I do not insist that anyone modify their stove if they do not want to. I am simply relating something I did that worked pretty well. Use it and enjoy if you feel it might be something you are interested in doing, otherwise, don't! We'll still be pals!

Comments (36)theplayer... it is confusing. Here is what I have learned: The old style looking RCS with the slotted vents on the front were configured with the simmer, 2x15k and an 18k burner. The new style RCS without the slotted vents in the front (like I bought) have a simmer and 3x15k burners as a way to cut costs. When we were in the process of purchasing this new style RCS the on-site BlueStar rep was hawking the new style range as having the simmer, 2x15k and an 18k burner... the rep was apparently not educated on the new style burner layout and telling us the burner layout was the same and did not change from the old style RCS. Since the 18k burner was the selling point for us to buy this new style range, along with the new look, we held the appliance store to the rep's word. In short, the new style RCS does not come with an 18k burner unless it is ordered as an upgrade....See More18" or 9" Ventahood for Bluestar RCS?
Comments (9)There is adequate ventilation and there is optimal. We work with the kitchens and budgets we have. Since you apparently have the budget and the room for it in your kitchen, the PRH18 will be more optimal than the 9" high models with your RCS range. I'm assuming you meant the NPH9 or PRH9 models when you referred to 9" Ventahoods. Is that correct? An NPH9 or PRH9 will not necessarily be a bad choice. They will just be less optimal than the PRH18 with your 36" RCS. To oversimplify the treatises that Kas mentioned, consider the following: Hood capture design and coverage area are as important and maybe more important than sheer CFM numbers. The 18" tall PRH 18 has a decent canopy making it more optimal for your RCS stove than VAH's sleeker and shallower VAH 9" models. You can get the PRH18 in a 42" width which further enhances capture from the outer sides of your 36" wide RCS stove top. I believe that the widest NPH9 and PRH9 models are a less optimal 36" wide. The PRH18 is 24" deep which gives better coverage and capture over pots on the front burners than the 21" deep PRH9 and NPH9 models. Whatever you get, do not overlook make-up air MUA. We are talking real-world laws of physics as much or more than code requirements. OTOH, the low speed on your 600 CFM motor/fan might be significantly quieter when run at low speeds for those times when you do not have flaming woks going simultaneously on all six burners of the RCS at once....See MoreCostco BlueStar RCS version
Comments (6)My Bluster range was just delivered in January 2018 and I too thought I was getting the newest model (RPB304BV2). My serial plate looks suspect at best (the over printing looks counterfeit in my opinion) and reads (RPB304BSS). Internet searches showed the BSS was discontinued in 2011. When I inquired further I was told it must say V2 somewhere in the model #. Please help, I attached a photo of the serial plate, I don't see V2 listed anywhere....See MoreAnyone with a BlueStar 36 inch RCS Sealed Burner Range?
Comments (32)The glowbar igniters are a really old and proven technology. You'll find it in lots of gas appliances (e.g. water heater, furnace, ovens, ...) as they are so safe. Whenever the thermostat calls for heat, it turns on the igniter. As a first approximation, a glowbar igniter is the same thing as an incandescent light bulb without the protective glass shell. It draws a couple of hundred watts and uses that to produce heat. Right next to the glowbar is a temperature activated gas valve. As long as no heat it produced (i.e. glowbar doesn't call for heat or glowbar is defective), no gas flows. This is very safe. But if the valve detects sufficient amounts of heat, it opens and gas flows over the glowbar and ignites. This is damn simple and there is very little that can fail catastrophically. So, it is inherently a safer design than using click igniters. Those are good for the stove top where a person can supervise the burners. But the oven has to work even when it cycles on/off without human intervention. The downside, of course, is that this glowbar behaves just like an incandescent bulb. Some bulbs live for decades, most live for a couple of years, and a small number dies within months. Same is true for glowbars. Nothing much you can do about it. Fortunately, they are cheap and standardized components. Every appliance manufacturer buys from the same factory. And yes, gas ovens always cycle on/off completely. There generally isn't a great way to modulate heat output. This is a noteworthy difference when compared to electric ovens, which frequently can keep constant temperatures much more easily. For many dishes, that doesn't actually matter. But there are some that do in fact cook much better in an electric oven. And I guess the reverse is true too....See Moremojavean
