I was told that the plumbing was different throughout for the different gases if you didn't want BTU loss in a conversion, which is why Wolf and BlueStar have different models for the different gases. I know that DCS and others that create their ranges for NG do have lower BTU ratings on the higher output burners for LP after the conversion. Why do you want to convert rather than order for what gas you have?

I don't have any experience with these expensive stoves. However, my impression is that they are designed like old classic simple stoves and therefore would probably only need a specific gas regulator designed for propane. I looked on the Bluestar site and their install manual is listed. Here is what appears to be the answer I expected for you. This appliance can be configured to work with either natural gas or LP gas. Verify that the appliance and the incoming gas supply are compatible. Check the rating plate. 3. The gas supply line must be the same size or larger than the gas inlet of the appli- ance. Your appliance has either a ýâ NPT or þâ NPT gas inlet connection. We recommend the supply line be üâ NPT larger than the gas inlet of the appliance. 4. Sealant used on pipe joints must be resis- tant to LP gas. 5. An installer provided manual shut-off valve must be installed in the gas supply line ahead of the appliance. This shut-off must be easily accessible in case of emer- gency. 6. All gas cooking equipment must have a pressure regulator on the incoming service line for safe and effi cient operation. This appliance is equipped with such a gas pressure regulator. Incoming gas pressure should be checked with a manometer. The correct manifold pressure for natural gas is 5.0â wc. For LP gas the correct manifold pressure is 10â wc.

Does anyone happen to have the Natural Gas hood orifices for their Jenn-Air gas range that they no longer need? I purchased this range a little over two years ago. It came with the natural gas orifices but we were LP so we used the conversion kit to convert. We are now converting back to Natural Gas and I can not locate my original natural gas orifices. I have not been able to locate Natural Gas conversion kit and Jenn-Air is currently trying to locate part number for me to order.It seems everyone has the LP conversion kits but no one has the Natural Gas. I know I should have done better keeping up with the originals but I never knew they would be so difficult to replace. If anyone happens to know the part number for the Natural Gas orifices I would like that information also. Thanks!

I like that my Wolf has the same power, high and simmer, on all burners. I believe in the dual ring of flame over Thermador's star burner. If I wanted the star shaped flame, I'd go with BlueStar. I don't know which Wolf you're going for...the open or sealed burners...but my open burners have 1 grate per 1 burner, so they're not too heavy and awkward to move, but the Thermador and sealed burner Wolfs have 1 grate per 2 burners, so dbl long and dbl heavy. Wolf has the higher BTU ratings. Do you have natural gas? If you're using propane, the Thermador offers only 13K BTUs instead of 15K it offers with NG. The Wolf is designed for the type of fuel used, so there is no BTU difference. The other reason I didn't consider Thermador, which probably doesn't apply to you, but we wanted a 48" with all burners and no griddle or grill, and they didn't offer that configuration. I think Thermador has a 1 yr warranty where Wolf has a 2 yr. The only problem I've had with my Wolf is that the grates had little rubber feet that degraded very quickly. They make a new type of grate now, which they sent immediately. They also sent new underpans, since they weren't 100% sure the new grates would fit the holes in my original ones. They did fit, so now I have 2 sets of the underpans, just because Wolf didn't want me to be inconvenienced with a 'wait and see' plan. The great reports about their customer service is what pushed me the last bit toward deciding for Wolf. I obviously haven't used a Thermador to compare. I am very happy with the performance of my Wolf. Not all that crazy about the shiny black under pans for cleaning, but at least I can take them out when necessary. I was concerned about the sealed vs open burner issue on models like Thermador. But you will hear both sides of that argument here, and it seems to have to do with personal preference, as well as cooking and cleaning style.
