conversion of gas to LP

Mojo15 Apr 10, 2009 09:14 PM

I have propane and am considering a new range. I was just told that a Wolf could come factory made for propane vs using a conversion kit that reduces BTU efficiency by quite a bit. Anyone know anything about this?

    Almost all Pro-Ranges ,THERMADOR,WOLF,VIKING,VULCAN are from the factory equipped with your choice of fuel.The world wide market is so big that dishwashers,
    clothes dryers etc are offered with both types of gas.
    I just purchased a THERMADOR 36" range ,propane ready from the factory.My retired 62"
    VULCAN was about the only game in town 20 plus years ago for "factory propane" instead of conversion.(maybe import exceptions)
    Most dealers are up to speed informationaly.WOLF et all have great web sites and 800 numbers.As are our propane people in the DC area

      Don't know what you mean by "reducing BTU efficiency." Actually propane burns somewhat hotter than NG. I converted my cooktop to propane and it's done just outstanding. Had to replace the jets in the burners and the regulator, very easy conversion.

        BTUs are a measure of heat, not temperature. The BTU rating of a burner is unrelated to the flame temperature.

        That aside, I installed a prosumer range some years ago, and had to have it converted for use with propane. At that time I believe everything on the market required a conversion kit, with about a 10% loss in rated BTU output going from NG to propane. From what others are saying in this thread, it sounds like some ranges are now designed specifically to produce the same BTUs using propane, which would require a complete redesign of each burner and not simply having the factory install the proper orifices and adjust the regulator, which would have no advantage over the retailer or consumer doing the same. If so, that's great, but I have to admit I only very rarely use my burners at full output and I don't feel at all disadvantaged by getting only 90% of what NG would have produced.

          No, with a properly designed burner, you can adjust the burner so that there's enough oxygen available to burn enough propane to produce the same heat output. That costs money, though, so many stoves don't use them. They've also got more parts to get out of adjustment, so there's another economic factor at work.

            Well, I'm not sure. My range is a Thermador - some love 'em, some hate 'em, but they're sure not inexpensive (about $1K per burner) and the conversion involved a 10% BTU loss. I see from an earlier poster that Thermador and Wolf (at least) now come set up for LP from the factory, which appears to be a change - definitely on the Thermador and likely on the Wolf because the dealer at the time warned me that the Wolf design uses two orifices per burner. So as I said, and I think as you said, if they're coming already set up from the factory it likely involves a different burner design, and if so that's great.

              all 11 of the PRO BIG BOYS come "ready" for ? your fuel choice or duel,DACOR is the only limited duel player in the game I think (electric oven,burner choice)
              As nearly as I could tell working out choices (mine and clients) all are ready with wrinkle free options

                Just my thoughts.. but thinking the other poster meant most range manufacturers offer your choice of fuel type ranges.. not specifically "dual fuel"

          I just posted a similar question regarding LP. When I check out manufacturer's websites, they give the BTU output for both natural gas and LP. The LP is sometimes dramatically lower than the natural gas output (over 1/3 lower). For example, the GE Profile PGB910SEMSS has a Powerburner that gets 18K BTU on natural gas, but only 11K on LP. That is a huge penalty. A couple of folds suggested that I go with induction, but that would mean tossing all of my Calphalon (not sure about the Le Creuset).

            wmanning: "A couple of folds suggested that I go with induction, but that would mean tossing all of my Calphalon (not sure about the Le Creuset)."

            I was one of those folds (fortunately not creased, just gently stirred in). ;-) Although I was not present when you purchased your Calphalon pots, here's betting that you paid less than $250 for all of them. You have received some value using them over the years, so apply a discount to that original value; and now you are thinking (according to the other thread) of spending $2,000 or so on a replacement range. Viewed in that light, does it not seem that you are letting the tail wag the dog?

            If you live near a Tuesday Morning store, check out the cookware aisle. Last week, our local Tuesday Morning had quite a variety of induction-ready cookware from several big name makers, including some interesting-looking Berndes "Injoy" line cookware, and it was very reasonably priced.

              Sorry about my typing skills, FOLKS. I am keeping an open mind about induction. I think I just have gas envy (cooked with gas for many years), but got stuck with electric when we bought our current home. Thanks for the advice.

                Hey, no harm, no foul. I trust that you noticed the smiley emoticon in my reply. In a cooking forum, I just could not resist a pun on the word "fold"; sorry.

                I also started with gas and used only gas for many years, then (in 1977) we purchased a house that had no gas connection, and we were stuck with an electric range for more than two decades. We switched to induction ten years ago, and now, if we bought another house that had a gas range, even a pro-style gas range, the first thing we would do is take it out and replace it with an induction cooktop. Induction is addictive.

          I purchased a gas range and had it adapted for propane, and at the time did some research -- including on this board! Propane burns less hot than natural gas, but not so much that you would notice, particularly when you have a super-duper Wolf. I think it was 10% or so.

          The best thing IMO about top quality ranges is that you can get super low. I have to do that with a heat diffuser.

          1. CindyJ Apr 11, 2009 02:52 PM

            We have propane, also, and when I bought my gas cooktop about a year ago I did quite a bit of research before I decided on a brand/model. If I were to generalize, I'd say that the less expensive models come with a propane conversion kit, which results in a loss of BTUs. In some cases, this loss is substantial -- up to 20% BTU loss. However, the higher-end brands I looked into came factory-ready for propane and there wass no BTU sacrifice. I ended up with a Dacor propane cooktop and I'm happy as can be with it. If I were shopping for a gas cooktop or range today, I'd make sure that it was manufactured for use with propane, and that it did NOT require a conversion kit.

              You specify from Wolf whether you want LP or Natural. Under my burner plates is written LP....which also needs to be specified if you are getting a unit with an infrared grill.

              1. Fritter Apr 14, 2009 02:57 AM

                I have a range converted to LP but not one of the brands listed here. Conversion was no problem at all even on a standard consumer range. Some brands advertise a loss on BTU while others claim zero. IMO this is nothing more than marketing.
                Nearly all come with a set of jets that are swapped out from NG to LP.
                Your profile is rather interesting for some one considering Wolf.

                  What a comment, Fritter. I am new here, what IS my profile? As far as I know, I didn't fill it out. I have found out that most of the better stoves come made for either LP or propane and so do not need the conversion kit.

                    Well, Mojo15, you DID fill out some info on your profile. Either you did or it just magically appeared there.

                    Your profile shows a blog name of "blue star ovens" which is obviously a competitor to Wolf... that's why Fritter mentioned it and I agree with them. No need to get fussy.

                    "BTU efficiency" is not an engineering term I ever heard of, so it's not clear what your source meant. Propane has twice the energy content than natural gas in terms of BTUs per cubic foot of fuel. What the propane conversion kit does is reduce the volume of fuel that goes to the burners, so you get roughly the same heating rate as you would with natural gas. The conversion kit is a lower flow rate regulator plus a replacement brass fitting for each fuel line going to a burner. There is a hole in the fitting. The hole is smaller for the propane version than the natural gas version. End result: less fuel volume but same heating (BTU) rate.

                      I am new here but have been lurking for some time. hanks for all the tips/tricks and range inputs. We settled on a 30" Dacor that will be here next week. We have (had) a 1999 model Wolf that we were going to convert to LP for the new house. The folks that purchased the old house decided to purchase it from us so now we have a conversion kit we dont' need. Anyone need a NG to LP conversion kit for a Wolf? CHEAP! Says its valid for models with serial numbers 11,000,000 and above. Thanks

                        I've got a year-old 30" Dacor propane cooktop, and I'm loving it! Of course, compared to my ancient Jenn-Air electric, probably anything would have been an improvement, but I'd buy the Dacor all over again if I were shopping today -- which is more than I can say about my new Bosch double oven.

                          I chose THERMADOR for my 60" range (I wanted all LPG and convection)when we retired the 60" VULCAN to an outdoor kitchen and DACOR for my 2 wall ovens ,and would do the same thing again

                              I don't have a conversion kit. What I have is a wolf rangetop rt-486g currently set up for natural gas. I need to convert it over to propane gas. So I'm looking to exchange parts with someone or sell the parts off the one I have. I can be emailed at mikeand wendy88@live.com
