Moraflauta: For the Broan MUA systems, have a look at these links: http://ths.gardenweb.com/forums/load/appl/msg010822599493.html?6 http://ths.gardenweb.com/forums/load/appl/msg0313214523464.html?40 The second link is titled "Braun" but they meant "Broan." For finding contractors, I'd start with my local government's building department/code enforcers and find out if they've ever inspected any kitchen hood MUA systems -- if so, ask who did the work. Also, I would try calling any local retailers who sell higher-capacity range hoods (if anybody local sells them). Also, there have been discussions here at GW where folks have owned-up to using exterior-venting 400 cfm OTRs with pro-style ranges. Heck, if your stove is against an exterior wall, you could even vent the existing OTR and work with that for a while. Almost any overhead vent-set-up will do a better job than the downdraft and recirculating vents you now have. A 400 CFM hood would be better, even if not as good as the venting could be. We have to work within our budgetary, spatial and architectural constraints, Wekick: Specifically I would love it to go low enough to -hold an 8 qt pot of mashed potatoes in enameled cast iron. Can you do that with your Wolf range? I've done that with induction but very low gas flames seem a little too concentrated to evenly heat the cast iron base on my LC enameled CI when I've got mashed potatoes in them. Of course, the burners will do the stupid melt-chocolate-on-a-paper-plate trick and I haven't needed a double boiler for years even with my previous GE DF range. Holding mashed potatoes on a gas stove-top is the one task for which I've needed a dispersion plate/disk/flame tamer. Todd or any of you folks with a BS or AR have any better luck with the star-shaped open burners on your ranges? Maybe I just don't put enough butter and cream in my mashed potatoes? ;>) This post was edited by JWVideo on Tue, Feb 4, 14 at 16:23

Mandy Lopez (mlopez@bluestarcooking.com), or Michael Allen(mallen@bluestarcooking.com) There is a door with a completely different hinge available.

Here I am again, for those of you who might still be interested: Yesterday morning, at 7:20AM, the service contractors came back to fix the problem I had with my simmer burner. It is one month since I first called Bluestar about the problem. They agreed to do the repair even though it was more than a year since I had purchased and installed my range. They called back promptly, answered all my questions and sent the service company out without delay. When the first team couldn't correct the problem another part was ordered and in a few weeks I was called to make an appointment. I was offered an earlier appointment but I wasn't going to be available for that time so another time/date was offered, which was yesterday morning at 8. I was called to confirm on Friday afternoon, and called yesterday at 7:15 to be warned that the men would be at my house in 5 minutes. The team included one guy who had come the first time around and another, who said he was the service supervisor. I didn't hover this time around, (it was before my first cup of coffee.) But I know they changed the ceramic igniter, opened and made some adjustment under the front panel, switched positions of the 2 rear burners (my request for which I agreed to pay $75), switched the gas nozzles (I know that is not the right term but its all I can think of calling those right now) so that the BTUs were correct for the switched burners, and adjusted all the flames. The stove is working like a charm. There's no more clicking, the simmer burner simmers and all the burners have a full flame range. They also tightened one of the knobs, that has recently begun to slip off. It is all good. I now have the pro-style range I have always wanted, and just in time for a houseful on Thanksgiving (20+ family and friends). There will be 2 turkeys, all the usual sides, more pies and cakes than we can possibly eat and some decent wine and beer to wash it all down. Hurrah! Thanks for listening. I am quite satisfied with the response I got from the people at Bluestar and the local service company.

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.
