What is a "local safety officer"? What do you mean "a bunch of back and forth" with your "local safety officer and Wolf"? What prompted you to use your CO meter to test the levels? They are employed by our BC safety Authority who are the regulators for all regulated work, gas and electrical and such. As a licensed gas fitter I hold my ticket through them and they are the final say when it comes to appliance safety. Permits and approvals for equipment go through them. I chatted at length with him about the stove and he did agree we can’t do anything because it meets ANSI standards being below 800ppm, but he did say he wouldn’t have it in his house. His advice to me was if Wolf won’t do anything to then adjust the burner input by under firing the appliance to bring the CO back inline. I went to Wolf with this information and they said ‘based on your requirements I don’t think Wolf products will be right for you, would you consider a buy back’. Checking CO is very common here in Canada especially when commissioning an appliance. I didn’t mention the CO alarm going off because it never went off, however it did show peak levels in the 15-19ppm range after cooking for a short period of time. Enough to make me concerned with a pregnant wife and 2 yr old. This is what will happen if you in a room where the CO levels are 800 ppm. The ANSI standards are referring to the CO levels in the air coming out of the range vent. 800 ppm air coming out of the vent does not translate to a room concentration of 800 ppm. Especially if you have your ventilation on. Now, if you were getting 250-300 ppm where the cook was standing, that indicates a concentration of way more than 800 ppm out of the vent, and thus a violation of ANSI standards. Either way, those readings were way too high and Wolf's response was poor. Yes, I agree, somewhat. The stove should never be operating at the ANSI levels, your house would build up to a dangerous level of CO over time ie. When cooking a turkey for hours. Our utility will actually shut down any gas range over 540ppm during normal operation. Also they shutdown any other appliance if its over 250ppm while operating. I agree we need ANSI standards but as new homes get built tighter and with less makeup air having a cooking appliance pumping 800ppm at the vent/flue is insane. Consider this regulation was put in place in 1926, buildings have changed considerably since then. So, what happened when you tried adjusting it? Was 250-300 ppm the lowest it would go? That would surprise me, I have adjusted several gas ranges and have usually been able to get them down to 30-40 ppm from as high as 500 ppm. I knew this question would pop up, but yes I went through the full range of what is reasonable on a brand new appliance. Below is what I went through, to try and reduce the CO: Tested inlet pressure, adjusted within 1”wc of manifold pressure. ‘Wolf recommends having inlet pressure within 1” for proper operation’ – no change Checked flip top regulator and it was set to natural gas Checked manifold pressure on stove it was at 5”wc Verified orifice was correct as per spec sheet supplied by Wolf Adjusted air shutter, no change was actually higher and this was the lowest I was able to get the stove to run at CO tests were done after 10-15 minutes of operation and the burners were warm Clocked meter to verify burner input is correct Verified no blockage in burner tube Verified all secondary air ports were free and clear House is still very drafty, so not a lack of air within the house The only thing I never did was under fire it, as I didn't want to go down that road on a brand new piece of equipment. Wolf blew me away with their service and willingness to make a customer happy. From a cooking standpoint however, it will be Bluestar for us.

maire_cate and Wekick Thanks both. I think I've watched Trevor's video before. the simplicity of the BS is very similar to my Russell range except everything in the Russell is stainless. (which I do like) I'm not terribly concerned about service as there is little that can go wrong. Having a high BTU kiln I'm used to taking he venturis apart and cleaning the burners. So I'm comfortable working with burners, cleaning adjusting. Unfortunately, there is no BS dealer close. I've watched all of the BS videos to ad nauseam drove to Las Vegas some months ago as I was told I could see one and try it out. They had a range which I would think is similar to a range top. They knew nothing about it. It was not live, disappointing to make a 5.5 hr trip for nothing. Next closest is Salt Lake city a 8- 9 hour round trip. Maybe when I get close to actually buying I'll make the trip and spend the night.. Trevor wrote his phone number on one of my posts suggesting I call him. Haven't done it yet and of course the paper I had has disappeared from my desk. Sales person also told me how wonderful Wolf ovens were. Yikes, I remember reading about your pain Wekick. When I mentioned the blue enamel chipping there was just a blank stare. I told him I plan on getting the GE French door wall oven as I have one in the FL house and like it. . When I asked if he can give me a deal on SZ (side by side and wine cooler) if I buy all of my appliances he said no they are sold at full price unless I purchse a suite of SZ/Wolf, which isn't going to happen.::(( There is a Ferguson in town as well. I don't think their set up is nearly as large but will head there one of these days. The only thing I'm still on the fence about is the dishwasher. Do I get another Bosch which cleans really well but doesn't load very well with my handmade dishes. Maybe by the time I actually get to remodel, Bosch will have improved their interior set up...I'm hoping. Inga

@Denise Meyer, I have the 30" gas F&P range. Things I love about it: Powerful, responsive burners. Stainless steel top (I much prefer it to the black enamel) Telescopic oven racks (come standard with the range) Soft close oven door Things I don't love about it: No low simmer burners (1,000 BTU is the lowest) The oven isn't real large but it suits my needs. I don't bake much or cook elaborate dinners where I need a large oven.

@Timothy Fisher ”would you consider triply pans as highly conductive?” There are huge differences in these pans. This guy has done a lot of studies and ranks some here. https://www.centurylife.org/cookware-even-heating-rankings-butane-propane-natural-gas-etc/ The nonsticks are all pretty good because they tend to be aluminum. I think you would almost have to try the burner to see how much flare it has on high. Also I don’t see 3 rings but two. I guess three choices, inner, outer ring or both. This is a screen shot from a video of GE’s burner with a 12” pan. I don’t know if this is the highest heat. Typically on this type of a dual burner the middle burner doesn’t carry many BTUs so still basically a single ring burner. As you turn this up the burner ports are along side the rays and the flame stays to the middle. This is why it is good for woks. This may be one of the smaller burners but the principle is the same. if you cook with a lot of wider pans on high heat, the GE is probably fine.
