Advice needed: Island range hood for 48 inch bluestar cooktop

7 years ago

I am looking for an island hood for my BS 48 with 4 burners on the corners and a 24 in griddle. we have 14 foot ceiling and plan to vent straight up into the attic and through the roof. We like the sleek look of the chimney style T hoods. We are so lost with what to do on this, and feel like I can't get an unbiased recommendation. We also don't want to spend $4000 on a hood. I really appreciate any and all help. Thanks. Here are my questions:

do I need a 54 inch hood or can I get away with 48 due to high ceilings?

is 24 in depth enough or do I need 27?

is 940 ffm enough or do I need 1100-1200?

internal or external blower?

should I expect to be able to buy what I need for $2000 or am I being unrealistic?

You're being completely unrealistic to plan to spend that much on a range and only 4K on a hood, much less an island hood, which is an order of magnitude more expensive than a standard wall mount hood. It has to be fiished 360, and needs to be much wider and deeper with more CFM than a wall hood because the air currents in the room will interfere with the capture. Plus, you'll have to deal with make up air as an expense as well. And a custom duct cover for your extra tall ceiling, which probably will be more than 2K just for the duct cover. The venting may end up being more costly than the range. You should at least plan for a 50/50 split in the costs, and if it ends up being less, be thankful.

Plus, to do a island cooking zone with a range that large will need a 12' island at least. Bigger if you want a prep sink there. Which you should, since cooking is only 10% of the time you spend in a kitchen but prep is 70%.

First of all, let me say I pine for a 48" with 24" griddle...my dream range!

Now let me add my first hand three year experience; I have a 36RNB with griddle which gets three or more times a day use. I have a 36"x27" Prizer island hood mounted 36" over the grates. The blower is a 1000cfm remote roof mounted. I would honestly say my set up is adequate, but marginal. If I were to do it again, I would go for a wider (42") hood and perhaps the 1400 cfm blower. I really don't think you can have too much ventilation.

For your set up I would recommend a 54"x 27" with as much cfm as you can get, external blower if possible, and no I don't think you are going to get the hood you need for $2k maybe not even $4K, but in the long run it will be money well spent.

Enjoy that Bluestar, and happy cooking!

So, is this 48-inch BS in the staff quarters or where guests will congregate and chat while food is being prepared? If the latter, then you want the quietest possible high flow hood. This entails at a minimum a roof-mounted blower or remote in-line blower and an in-line silencer on 10-inch ducting. My usual recommendation for actual air flow rate capability for a baffled hood with an assumed 8 square feet of aperture is 720 cfm. This calls for a blower rated at least at 1080 cfm at zero static pressure, but given the possibility of some combination of cooktop and oven use where oven spillage is the most difficult effluent to capture, I'd aim higher. For an island setup, I'd aim for a 1500 cfm rated roof blower. With a wall set-up 1200 should do. (For most cooking you would operate at a reduced blower setting and there will be little fan or baffle turbulence noise.) I use a 1500-cfm rated blower with my Wolf (Independent) Pro-Island hood with a 10-square-foot aperture, but don't have a griddle and have another 1000 nominal/600 likely cfm capable vent over the separately located ovens. A suitable source of (possibly conditioned) make-up air is also necessary. kas

I have the Zephyr Monsoon DCBL series, but that is an insert not an full hood. But I like the brand and have no regrets going with it over my 36" BS Range Top. It is not wider than the range top and probably could be deeper, but for our cooking style it has not been an issue. Prior to our kitchen remodel we only had a OTR microwave and the vent from that, which was vented to outside. But any time we cooked almost anything in that setup we would set off the smoke detector in the kitchen. And, since our town home has the smoke detectors all hardwired to each other, they all went off. The smoke detector is about 15 feet or so away from the cooking surface, maybe a littler farther. Since we have gone to the BS range top and the new Zephyr hood we have not set it off even one time in 6+ months now. I know that an OTR hood and a real vented hood are not the same, but just wanted to point out that with the higher heat output of the BS compared to our old wimpy 4 burner GE range, we have not had any issues to speak of and I would recommend the Zephyr brand based on that.

I love our 48" Viking. There is plenty of room when dh and I are cooking at the same time and the extra space also comes in handy when I'm cooking alone. I love having unused burners to slide hot pots onto for cooling off or as landing space for hot items from the oven. It contains all the hot items to one space instead having them scattered across the counter on trivets. And there are times when all of our burners are used at once (we have 6 + a griddle.) I use the small oven most of the time for our family of 4. The large oven is handy when I cook mulitiple items at the same temp or when I use large cookie sheets. Having 2 ovens comes in handy for different oven temps and for when one oven is tied up by something baking for an hour that shouldn't be disturbed. Take your favorite baking dishes to the showroom to make sure they fit into the small oven. The dishes I brought were a 9" Pyrex pie pan and a 9x13 pan. They fit fine in our Viking but didn't in some other brands. The brand I was leaning toward got eliminated because the oven rack brackets decreased the usable space so much that I couldn't fit either of the 2 dishes I brought. Just reading the oven specs wouldn't have been good enough since it seemed the oven was plenty big. Dh was happy we ended up with his top choice by default. I would definitely buy another 48" range if I had to do over again. Getting a range with 2 ovens and plenty of burner/elbow space was a splurge that made a lot of sense to us.

Not only should the hood sides overlap the range cooktop, (60 inches may do vs. 48 for the range), but similarly the front-to-back aperture distance must be sufficient to overlap the range cooktop. The VaH drawing shows 30 inches, perhaps enough, although it is unclear how much of that might be lip or controls. Assume none. With an entrance aperture of 30 x 60 or 12.5 sq. ft. under the hood, at 90 CFM per sq. ft. the actual flow should be 1100 CFM -- probably adequate even on an island -- so long as there are no significant cross drafts. However, a magic lung isn't magic. The most we can generously assume is that the hood hanging in the air can flow the rated 1100 CFM. What it can do with some length of ducting, a roof cap, and a make-up air system imperfectly attempting to make the interior air pressure to outside air pressure equal is not knowable without analysis. I would go for a higher flow rate, ca. 1700 CFM. With care and expense, maybe 1500 would scrape by, particularly at 30-inches height, where the hood may block the view of taller cooks. A side view stick figure mock-up is recommended. Also, I am unclear how effective the entire entry aperture is, without more detail about how the incoming air meets the blowers and how the blower structure interacts with it. Pro style baffle type hoods are, in their way, somewhat less complex internally if the blower is moved to the roof where it belongs.

You really should post your layout on the Kitchen Forum. Island cooking is darn expensive, and there are more functional choices for most kitchens. Don't build in dysfunction and expense when you have the opportunity to build something better from the beginning. Kitchen work follows the 70/20/10 time split. Prep/Cleanup/Cooking. Make the most of your work space by designing it to take advantage of that division. Put your effort into creating the best prep zone that you can design.

If you keep to your original plan, yes budget an almost equal amount for a complete ventilation system as you do for your cooking system. Also, double check your space constraints. A 4' range is a giant space hog and would overwhelm most standard kitchen islands.

The other thing to think about (as some of us swelter in the 90 degree summer with the a/c cranking) is that the cavernous high-CFM hood that you will surely need (that high up over an island you should be minimum 3-6" beyond the range and that is overly conservative) will also be sucking your expensive heat and air conditioning out of the house. The harder it has to work to capture the free flowing smoke/steam/vapors, the more heat/a/c your system will need to pump out to compensate. So count me as one more vote for wall range placement and island prep. You can always add one of those serpentine prep sinks if you want to add a little something extra to the island.

There is a lot of hood design rule information posted in response to similar questions on this forum, and these ventilation topics should be reviewed for basic information and understanding. (This will take a while but is important in separating wheat from chaff.) Please feel free to ask specific questions, including questions about confusion resulting from our comments. Key search words that might be used in Advanced search on Google, using ths.gardenweb.com as the search site include:
- Capture and containment
- Pressure loss
- Fan curve
- Make-up air (MUA)
- Hood overlap
- Baffles
- Mesh filters
- Blowers (hood, in-line, roof)
- Silencers
Two essential concepts that drive the ventilation system solution are (a) the effluent rising from hot pan surfaces expands as it rises at significant velocity and has to be captured by the hood aperture and contained by the flow rate and filter/baffle system, and (b) all the air moved out of the house by the hood system has to be replaced somehow.

For a commercially-oriented presentation of the subject, see the Greenheck link below. The key to proper ventilation of "Pro" residential cooking equipment is to understand that it derives from commercial equipment, and ventilation requirements follow the same rules, if not the same scale.

dueceluxe I'm not sure if you ever got an answer to your question, but I'm going to chime in because in 2008 I was in the same boat. We have a 48" BlueStar in a 12' island, with a prep sink located about 48" away, which is where I spend my prep time. Frankly I wish people would focus on answering the direct questions, vs. lecturing about what percentage of prep/cook/cleanup time people "should" be spending in their kitchens, or in which direction they should be facing when doing so. The OP stated they were looking for an island hood for their cooktop, not IF they should be putting the cooktop in the island. For us personally, my prepping and cooking is very intertwined, and we entertain a lot. Ergo, I want to be facing my guests while prepping AND cooking, and not facing my guests during cleanup (THAT sink is behind the prep area against a wall), so the cooktop in the island is what we did and we (and guests) LOVE it and wouldn't go back. It's not for everyone, but it's definitely right for me.

Having said all that, yeah, sadly the hood is going to be expensive. We went with a Best by Broan IEX222 51" with a 1500 CFM externally mounted blower. The pros are that the thing will suck up ANYTHING at full speed. The con is that we've had it for 7 years, and unfortunately have gone through 4 control modules or transformers on the thing (everything on it stops working). So nn my frustration I'm now researching replacement hoods, which is going to be $$. It's the price you pay for the style you want. Currently evaluating Cavaliere and Imperial 54" hoods....
