Wolf AG - gas line pressure?

16 years ago

Hi

I am very interested in the gas line size/pressure in relation to Wolf problems that people have experienced. I just had my AG Wolf installed and the oven won't get above 400 degrees (and that's after 2 hours!). Wolf technician came out and checked everything and said the diameter of the gas line is too small. We have propane and the huge tank is located about 100 feet away from the house, with the line buried. It looks like the pipe is less that 1/2", then it goes into some kind of regulator right before going into the house, then on the other side of the regulator it is 1/2".

The Wolf technician called the gas company with all the pertinent information, but the gas company is dragging it's feet in getting back to me. Can anyone give me an idea of how big a deal this is going to be? We are in snowy Vermont, with a foot of snow on the ground, so I don't think they will be digging up any gas lines any time soon....Is it a matter of increasing the pressure or do we need a larger diameter gas line? Does a gas line from a propane tank have to be buried?

My problem is if we have to get rid of the Wolf (hopefully not!!), I want to get it out before the granite countertops and island get installed, which is supposed to happen in a couple of weeks.

Please, someone tell me this problem is fixable!

Thanks!

Our problems with the Wolf were not related to the lines/pressure. However, since you DO have issues and what you have isn't up to the specs that they state that will is the first thing they point out to you. I know they want a minimum of 3/4".

Also, call the gas company yourself and ask them to come out and check the pressure to the house and to the range. That will give a second opinion that isn't from Wolf.

I know there has been some luck with larger pipes but that was not an option for us and what was inside was within the standards.

It would also be a shame to have it all done and paid for and then still have issues and end up without the range anyway.

Hard call, really! Sorry, that isn't much help is it?

I'm not a plumber, so don't take anything I say as 100% accurate, just trying to point you in the right direction, also I am on natural gas. Yes the line from the LP tank needs to be buried. The good news is, I don't think you need to replace the underground gas line. My gas line, that brings the natural gas to my house, ending at my meter, and regulator is also 1/2" inside diameter, but that's high pressure, before the regulator. Of course once it gets to the regulator, it needs to be at least 3/4", maybe more depending on how long it is to your stove, and how many btus your furnace, water heater, clothes dryer uses. We didn't have a problem getting our Wolf past 400 when we first got it, and did the burn in, with the small pipes, our problem was trying to use the oven, and burners at the same time. The new pipes fixed our problem, but other people with the same problem have big enough pipes. Wish I had an answer for them.

Omg, wolf all the way. Your question is almost like asking "mercedes or chevy"? Lol :). I can not point you to any direct comparisons, but even if the wolf was less reliable it will still probably last longer as I truely believe that with the simplicity of an all gas professional range you could keep them going for 50 years or more. Wolf is probably also the most reliable of the professional ranges, although I do not believe that any of them are as good as they should be in that department given the cost etc. Plus as with the mercedes vs chevy comparison, you will get so much more "driving" pleasure from the wolf. As others have mentioned the AG will also give you an infrared broiler which I think hands down beats a traditional electric broiler, but on the flip side some people swear by electric ovens. But if an electric oven is important then I would say go for a DF wolf. I personally would get that ge out of your mind! :). I'd also look at Bluestar and Capital Culinarian. I won't say they are "better" than a wolf, cause I am unable to tell you what is best for you, but they offer a lot more power and probably as mentioned earlier more "driving" satisfaction. I had a viking which is probably the closest competitor to wolf before my bluestar and although it was much more satisfying than a more pedestrian range it really doesn't compare to the satisfaction I get from cooking on my Bluestar.

I couldn't say anything about accuracy at least recently (haven't checked it with an oven thermometer)--I know the Jade range we'd returned (and replaced with the Wolf) was never calibrated correctly, even after a tech supposedly calibrated it for us. At some point while we were involved with the Wolf AG burner issues/replacement ranges/"fix" I believe the tech did check to make sure the oven was at the set temp during one of his visits to work on the range we ended up with.

I'll explain my post (the 1st response to OP), but I won't get into a debate over which range is best, because feelings run high among some folks, and I respect everyone's individual preferences. For myself only (I have the 30" Wolf DF range), I never, ever Wok cook, so having instant, high heat flames is not, and never will be, important to me. I sautee all of the time, and the heat produced by my burners more than meets my sautee requirements. Likewise, while people sometimes talk about how many BTUs their ranges produce and how they can bring water to a boil in "x" minutes, that has never been important to me. The BTUs on the range I have are more than sufficient for the kind of cooking I do...which is home variety, often at a gourmet (but certainly not professional) level. I wanted a range that had wonderful low burner output and could melt chocolate without burning, could hold a sauce without scorching, etc. And the DF does that beautifully. I like the fact that 3 of the burners on the 30" range have a high BTU (I think it's 15,000 - but don't quote me), and the one in the back has only 9,000 BTUs for its high heat level. All of that works wonderfully well for the way I cook. So, bottom line, I recognize my needs may not be similar to people who are much more professional in the kitchen, who need a range with a higher level of performance. For my wants the DF range (with its wonderful convection oven, which I truly love) makes me ecstatic every time I use it, and produces fabulous meals.

Three+ years ago I remodeled, and replaced my electric stove with 30-inch DF Wolf (which I LOVE far more than I ever anticipated). My house was built in 1978, with gas heat and gas hot water heater. The plumber did run a dedicated gas line (flexible hosing) to the Wolf. Not a big deal and done as part of the remodel. I've never had a bit of trouble with the flame, output or performance of the Wolf burners. I don't think you're being misled by your contractor or plumber. Good luck. And have fun anticipating your new cooking adventures on the wonderful Wolf!
