Do gas cooktops still have pilot lights?
Comments (15)Check the installation instructions. What you do need with Wolf, and probably Gaggenau, is a dedicated electrical circuit for the ingniter. My electrician pooh-poohed that without telling me (my idea is follow the directions, but I'm just a girl...). It worked for a month or so, then failed, taking the plugmold nearby with it. Electrician said it was a short in the cooktop. Hearing that, even though they probably knew what the problem was, Wolf sent out a warranty repair man who had to unscrew stuff to pull the unit out and open it up. And then tell me that it was fine and wasn't on the dedicated circuit it was supposed to have. There are plenty of spots on the panel, and it wasn't a big deal (if you don't count the pot drawers living on the floor for a week until he could come out) to put in the circuit, so I don't know why he didn't do it from the beginning. If it says you need a separate circuit, believe it....See MoreGas Pilot Question
Comments (10)If the pilot tends to go out with the doors closed, it's because the flame is short on oxygen. Hard for me to imagine your doors are so tight to do that, but anyway, if that is the case, the thermocouple would prevent gas from continuing to flow if it went out. But to be extra safe you could either leave the doors open a crack to keep the pilot running, or get in the habit of turning off the gas to the pilot. As for CO2, I would think it's not a problem, since ventless fireplaces are used with the pilot running all the time. My folks have two and use them all winter long, leaving at least the pilot on, and that's in rooms without any vent or chimneys....See MoreCommercial ranges in homes (residential kitchens)?
Comments (0)[Information first compiled, written, and posted in the Appliances Forum by Colin (GW Member Page: cpovey) on 1-9 June, 2004. Many thanks, Colin!] ****************************** A Short FAQ on commercial ranges in homes (residential kitchens): One of the biggest trends in appliances is the "professional" look, meaning appliances made out of stainless steel. This trend was largely the result of Viking Corporation making the first "pro-style" ranges, meaning a range that looks like a commercial range but is designed for home installation. Some people, including myself, have thought of going all out, and installing true "commercial" ranges in our homes, because they are less expensive and produce more heat than the "pro-style" range. However, there are issues with installing "commercial" ranges in homes. This FAQ will attempt to answer these issues. To keep confusion to a minimum, I will refer to "commercial" ranges as the ones made for use in restaurants, and will refer to ranges made for home use as "pro-style". True commercial ranges are made by companies like Garland, Vulcan, Wolf, DCS, Comstock-Castle, Royal, Montague, American Range, US Range, Jade, Imperial, Quest metal works, Southbend, Blodgett, and the like, while the "pro-style" ranges are the ones made for home use, by Viking, Wolf, Blue Star, DCS, Capital, Dacor, Heartland, Jade, GE Monogram, Thermador, Imperial, etc. Yes, some companies make both. -------------------- Here is a list of the advantages and disadvantages of these units in general. Pros of commercial ranges: Less costly than home ranges. Higher output burners (generally 25k BTUs on restaurant grade, while the "heavy duty" models come in around 35k BTUs). Ovens usually hold full sheet pans (see note 1). Very durable. Generally no electronic gimmicks to break. Cons of commercial ranges: Insurance and warranty issues: With many brands, the warranty is void in residential installations. Here is a quote from one manufacturer: "The use or installation of our products in Non-commercial Applications renders all warranties, express or implied, null and void." (the quote continues in this vein for nine additional paragraphs). Insurance issues: you may have problems with homeowners insurance, though probably not, if the range is installed exactly per specifications. Whatever you do, if the insurance company asks if you have commercial equipment installed, do NOT lie to them. Lying to them creates a "Material Misrepresentation" which will void your insurance and they can refuse ANY claim you make. Installation and service issues: In homes with natural gas, the gas supply line is generally insufficient in size for a commercial range. Having too small a gas supply line seems to void the warranty of every unit I looked at. Generally require 6 inch or more clearance from combustible surfaces, with some ranges requiring up to 12 inch clearance. This generally means lining cabinets, walls, backsplash, etc. with tile, which lowers the savings. It also means gaps between the range and the adjoining cabinets. Less insulation around the ovens, which may cause problems in a home, especially with small children. You may have problems getting service (some commercial service companies do not carry liability insurance covering their service personnel in homes). Most are more than 24 inches deep, meaning they stick out from regular cabinets. Since most are deeper than 24 inches, custom hoods are generally required, again reducing the savings. And with the heat these things can produce, you need a good hood. And commercial hoods tend to be noisy compared to residential hoods, and often require makeup air, reducing the savings still more. Most require multiple pilot lights (generally one per burner and one per oven) consuming a lot of fuel, and eliminating over a few years the rest of the up-front savings. A typical 36" commercial range has seven pilot lights running all the time, wasting a lot of gas and producing a lot of heat. A 48" range with double ovens has ten pilot lights! Cooking and other issues: They generally don't simmer home size amounts well (i.e. they make too much heat) without a separate "flame tamer". Pros generally make larger quantities of stuff than people do at home, so the larger "simmer setting" is not a problem. No broilers in commercial ranges. Pros use a device called a "salamander" which is a broiler that is mounted at eye level, generally above the range. The advantage of this is that the cook can watch the food while doing other things, and it frees up the oven. Note that cooking things like steaks, hamburgers, etc. is NEVER (in my professional experience) done in a salamander or broiler in a commercial kitchen. They don't get hot enough, and they don't put grill marks on the food. That's what the grill is for. Salamanders are sometimes called "cheese melters", which is more descriptive of their common function. No option for built-in grill or griddle on most units. Not the easiest to clean - Pro kitchens have a dishwashing crew of very hard working people who get paid to clean things, most homes don't. Not the prettiest to look at. Most do not have stainless sides. Since they are usually deeper than most cabinets, this may not look good. Few, if any, are available as "dual fuel" models, most are all gas or all electric. No self cleaning units. Pros of good quality "pro-style" residential ranges: Elimination of all the problems mentioned above. This means they have sufficient insulation for zero clearance installations, they simmer home sized amounts well, have no insurance issues, contain broilers, often have options for grills or griddles, many come in dual-fuel or gas ovens, many have self-cleaning ovens, are never deeper than 27 inches, etc. In other words, they are designed and engineered for residential use. Most have no pilot lights, resulting in lower operating costs, lower energy wastage, less pollution, and lower electric bills when running AC. Note that in a loss of power, most if not all will allow the burners to operate by using a match or lighter to light the burners, but may not allow the use of the oven. Some brands available in multiple colors, instead of just stainless steel. Cons of good quality "pro-style" residential ranges: More expensive than commercial ranges. Not as much heat as commercial ranges. Most "pro-style" home units run around 12-15k BTUs, with some going up to 18-20k BTUs. This is sufficient for most people at home. Note that the "normal" home gas ranges typically top out at 9-12k BTU burners. Ovens may not hold full-size sheet pans (though some will - check this carefully before purchase) (see note 1). Some have electronic widgets (timers, etc.) that can fail, causing repair problems down the road as the required electronic parts are discontinued because of changing technology. Notes: 1 - A full-sized sheet pan has interior dimensions of 18 by 26 inches. A full-sized layer cake with two layers will feed 80-90 people. Half-sheet pans (also called jelly roll pans) are 13 by 18 inches, and a two layer half-sheet cake will feed 40-45 people. The reason that these pan sizes are important is that many recipes are sized to fit these pans. -------------------- How to get more heat: A partial "work-around" to get more heat for less money is to get a commercial (i.e. Garland, U.S. Range, Vulcan, etc.) cooktop and residential ovens. Many of the problems with commercial equipment in a home are related to the ovens, not the cooktops. Buying a used one avoids the warranty problems. However, the too-hot simmer, the gas supply issues, and potential service problems still exist. Another and probably better option is to install a residential wok burner (DCS, Thermador, Viking and others make these) or a heavy duty induction burner (CookTek and others) along with a residential range. Both of these options provide roughly 30k BTUs, in an easily installed appliance. These units are also not that expensive. -------------------- With permission, I have also included here a posting from another site (an online newsgroup). This article is from Adam Finkelstein, a dedicated and resourceful person who has installed a "commercial" range in his home. I edited it some, for reasons of length, but I tried to keep all the essential elements intact. "I currently own and use a Comstock Castle Six burner 36" restaurant range in my remodeled kitchen. I opted for the commercial for financial and practical reasons. Since I cook seriously and use tools functionally, after researching commercial ranges and using them in friends' restaurants, I arranged to have a Castle stove made and order it through a restaurant supply house as per Castle's recommendation. I had them modify a front burner to run at 45K BTU for Wok cooking. The stove arrived and we had it installed per code with all clearances etc. I had the stove approved for use before I purchased it. However, I'm still having a problem with the final building inspection since the stove is not a "residential" stove--pure bull, but a hassle nonetheless. My GC is going to iron this out eventually. These stoves are HOT. No messing around. I can have a saucepan (1 quart) of water boiling in ~60 seconds. I can make Asian food almost as if I was using a wok jet. Cooking is much faster and more precise. But, there is no room for error. If I neglect anything for a few seconds, stuff is overdone. I have had to adjust all my recipes to compensate for the change in actual cooking time/done-ness. Points to Consider: I have burned myself several times getting used to this stove. Heat radiates up and around the utensil and reaching across to adjust food, one can get seared/scorched. Any utensils that have plastic or composite handles will not last very long on a commercial stove and you will need to use pot-holders or dish towels to manipulate utensils. The stove makes lots of amazingly rich smoke. If you want one of these stoves, you'll need a real hood. Mine is 42 inches and has a 600 CFM internal fan. My 600 CFM hood/fan removes 75% of the most nasty greasy smoke from searing meat or serious Wok use. I was hoping for 100%, but I had to compromise (because of the maximum size ducting I could install). You'll need either a natural gas line or propane--propane burns less hot than NG but is still okay--what I have. You'll also have to wrangle with the company to have a 120 Gallon (400 lb) tank installed. We go through an 80 gallon load in two months: 40 gallons a month. This has been fairly steady, more in the Winter when we bake more. The line needs to be to code with shut-offs and disconnects. Not a huge deal but more details to manage in a remodel. Lastly, after being approved by house insurance and the local building code, you'll possibly run into some cretin-like inspector who will arbitrarily decide that your stove isn't allowed. But, if you have installed to code and specs you should be able to work this one out. I wouldn't want anything else after using this stove. Someone else posted awhile back that after owning and driving a high-performance sports car, why drive a sedan: this is true. If you want to save money and cook like you work in a restaurant (weird desires huh) get a commercial stove. If you have any doubt about high heat, necessity for serious ventilation, detailed gas line installation, and potential skirmishes from building code enforcers, do not consider a commercial stove. If you can deal with those factors and you want to use an amazing tool to make excellent food, then by all means, install a restaurant stove." Notes From Colin Povey (FAQ author) on the commercial range installation by Adam Finkelstein: Like most commercial ranges, this range is deeper than "pro-style" or normal ranges that are 24 to 27 inches deep. This range (per the web site) is 30.5 inches deep. Coupled with the offset requirement, the front of the range must sit 32.5 inches from the wall. Standard base cabinets are 24 inches deep. One way of looking at it is that this commercial range is 8.5 inches deeper than most cabinets, the width of a standard piece of (US) letter or legal paper, or approximately the width of a piece of A4 paper. The range sits on 6 inch tall aluminum legs or optional casters, with no front "toe kick" cover. Toe kick covers are not allowed on commercial equipment, because they make it hard to clean behind. You can get this range with griddles or grills. However, it would seem that the grill (charbroiler) is very hard to install in a home, since the literature says that: "Charbroilers are approved for use in non-combustible locations only." This means all surfaces around the grill must be non-combustible, meaning you cannot have wall cabinets real near this range, and you must have a non-combustible backsplash. The literature on the range also says that "All controls are tested and confirmed in good working order. Calibration and adjustments are the responsibility of the installer." -------------------- I hope this FAQ helps with your decision on getting a "pro-style" or "commercial" range.

Comments (7)>>>"How do you know the oven has finished preheating?"<<< Well, if you believe in little signals or lights, there is the little blue light to the side of the oven dial on the Blue Star ranges. (just saw john williams' post as I was uploading this.) But, bear in mind that virtually all oven preheat indicators are mostly measuring air temperature without telling you if the oven walls are fully preheated. It is the oven walls that are important for preheating, mostly. (I just give my oven 20 minutes or so to get preheated -- 30 minutes when a specific pre-heat temp is important for the recipe.) There have been numerous threads discussing this subject here if you want to do a search. Or, you could check out this link for a technical explanation: http://spectrum.ieee.org/consumer-electronics/gadgets/nathan-myhrvolds-recipe-for-a-better-oven >>>"What do you use for setting timers?"<<< I use a couple of Taylor 1470N units which have both timers and thermo-probes. There are better and more full featured ones (count up and count down timers, etc.) but these were what my local hardware store carried. These units also get used with my bbq grill and my smoker. Thermoworks makes some nice units. FWIW, I also have a Thermapen and find it very useful. Reacts much faster than the wired remote probe units. >>>"Do you keep a clock in your kitchen? "<<< Not since a guest accidentally knocked it down (Small kitchen, a mop handle, etc.) I do have a MW near the stove, though, and I wear a watch. I like timers over watches and clocks, though, because timers do not get disracted the way I sometimes do....See MoreUser
