Can anyone help me compile a list of vent hood models that vent straight out the back? I have everything bought except my vent hood. I am holding up the cabinet work until I find one. If you have a back venting hood can you tell me which model and brand? Thanks for your assistance, Peke

RE: back venting hoods

I have the Broan E60E36SS, which can vent either out the top or out the back. I have the remote blower version, but the internal blower version can also vent in either direction.

The lower profile Broan E64xxx has the same options.

Go to ajmadison and just start looking at hoods -- many can vent in either direction.

Kobe makes several that vent to the rear.

RE: back venting hoods

Some manufacturers make their range hoods with an option to vent straight out the back. I prefer to work with the Futuro brand products, they're good products and easy to install, and they have at least several models with a blower that can be rotated 90 degrees to exhaust straight out the back. It's very convenient when you have limited space above the range hood.

RE: back venting hoods

attofarad, thanks for the model #. I will check it out.

weedmeister, I heard Kobe does, but which models? I have looked on their website, but can't figure it out.

robert_sett, I haven't looked at Futuro yet, but will look for the ones that say they can be rotated.

It is very possible I just miss the part that tells me it is back venting. I have been looking for weeks. Thanks, Peke

RE: back venting hoods

We have a Kobe CH122-SQB undercabinet hood which vents out the back or the top. Several Kobe hoods have this option. If you go to the link below, you can get to the main list of Kobe products.

RE: back venting hoods

I am starting to wish I had not bought the Blue Star rangetop. Who would have thought finding a back venting vent hood that I can afford would be so difficult....

Here is what I found so far in case someone else is looking.
Zephyr Typhoon - 3 way (don't know what 3-way means.)
Zephyr - Tempest I - vertical and horizontal vent. Not sure if this means it goes vertical then horizontal...or either one.

Kobe CH2742SQB horizontal/vertical. (here we go again)

Cavaliere Euro AP238 - horizontal/vertical.

Problem is these are all 22" depth.Plus they all have halogen lights.


 o
RE: back venting hoods

When Kobe descibes the vent as horizontal OR vertical, that's exactly what they mean. You have the option of either. It does not mean it does one then the other.

I was interested in a Blue Star cooktop or rangetop, but the venting problem turned me to induction.

RE: back venting hoods

Thanks, I thought it was that but I wasn't sure. If I could just afford a $1200.00 -2000.00 vent hood I wouldn't have this problem.

RE: back venting hoods

It is quite possible that I am misunderstanding the back venting issue. Do they go straight out the back? Do they go up first then out the back?

I am trying to get a hood that goes straight out the back and that is 24-27" deep.

Thanks, Peke

RE: back venting hoods

"It is quite possible that I am misunderstanding the back venting issue. Do they go straight out the back? Do they go up first then out the back?"

I'm wondering if you're confusing this too. For example in my wall mounted under the cabinet vent hood system, with fan on the effluent wafts up through two adjacent 10" x 3 1/4" vertical holes in my old Thermador vent hood, then meanders vertically several feet within galvanized steel, then makes a 90 degree turn to run through the room behind where eventually a 10" round duct takes it to the 1000 cfm external blower on the roof (I figure I'm getting 750 cfm max if lucky due to the run).

So, while my vent apertures are vertical openings, the vent ducts first turn is horizontal. So yes, up first and then out the back for me.

I understand your frustration. I've been trying to figure out all the twists and turns of my ventilation system since March so as to know how to approach buying a vent hood which will work with the existing ducting (not vent hood but ducting) in place. The inside duct run over the stove (with vent hood removed) will be replaced and cleaned up, and a new 1000 cfm squirrel cage exterior motor added.

I would get a professional venting specialist in if time is of the essence.


 o
RE: back venting hoods

Regarding the vent hood itself:

Vertical venting is the punched out hole (aperture) in the vent hood you see from the top when looking down at the spec pictures of the hood.

Horizontal venting is the punched out hole (aperture) in the vent hood facing backward when looking down at the spec picture of the hood.

Hope this helps.

RE: back venting hoods

I spent all day yesterday and all day today looking for vent hoods on the internet. I wonder if what I want even exists.

I was going for 42" but will settle for 36" I guess.
I need 24-27" deep with a rear vent that goes straight out.
SS baffles, LED lights, 700-1200 cfm. Under $1500.00.

So I wonder if I can trade the halogen light bulbs for LED.
I have checked out every vent hood anyone has suggested, but they just don't fit the criteria. So maybe what I want doesn't exist.

I guess I should just settle for less cfm, less width, halogen, less depth.

RE: back venting hoods

Peke, Broan is a consumer friendly vent hood maker. They were the first, as I understand it, to design an economical make up air damper. They have a technical support site phone line for ventilation. Perhaps you'd find it helpful to give them a call. As I recall, their hoods were fairly reasonably priced. The do have back vent hoods.

The link below gives their technical support phone line as well as a faq question and answer sheet. Hard to believe Broan wouldn't have some recommendations for your specifics.

RE: back venting hoods

Peke, why do you want LED lights? My friend has them, and is already replacing expensive LED bulbs. Hot locations are not good for LED lifetime. Many, maybe all, hood LEDs put out less light than the 50W halogens.

I don't know whether you like this one, but I think it fits your stated criteria. I bought mine (external fan version) from fullhouseappliances.com for 15-20% less than AJMadison was selling for. That top stainless part is optional -- I have a cabinet there, over the hood.

The 42" has 1200CFM internal blowers (pair of 600's), the 36" has 600CFM.

I don't expect this hood to be quiet. Mine will, but it has a roof mounted 600CFM fan, and a muffler ("silencer") between the fan and the hood.

RE: back venting hoods

I did more research today and found that horizontal venting does not mean 100% horizontal like I thought. It means up then out. Rear venting goes straight out the back. Hope I have this right.

I thought they were doing away with halogen lights due to the amount of energy they consume. That is the only reason I wanted LED. So that is one problem off my list. I will get halogen.

I looked at that Broan once before, but it is made of 22 gauge SS. I was hoping for 18 gauge. It is also a vertical then horizontal vent.

I found 3 Proline hoods that vent out the back, but I do not know what gauge of SS they are. PLJW 102.42, PLJW 101.42, PLJW 109.42.

I appreciate all your help and advice. The search continues.
Peke

RE: back venting hoods

Peke,

As someone here once said, once the hood is in place, the gauge doesn't matter. It's not like a sink, where you could easily dent it by dropping a pan in it. Also, that's gonna be a heavy hood to hang.

You are wrong about the Broan being a vertical then horizontal (unless you want to install it that way). You either connect to the back vent and block the top, or the other way around.

I looked at the installation manual for the Proline -- if I was looking at the right one, it only vents out the top. So up then back. It is a good thing that the Proline has more lights at the back (heat or other) -- 20 watt halogens aren't all that bright, maybe you SHOULD replace them with LEDs.

Maybe I worry too much, but I also shy away from controls that look like I will not be able to replace them with something else, if they fail and the model is no longer in production.

RE: back venting hoods

Thanks, you were right about the Broan. Somehow I missed that back cut-out. I am leery about the Proline Hood since so many people had trouble with them.

The Broan E6042T series sounds like it might work. I wish it was 27" deep though. If I can't find a deep one, I will get the Broan.

I also found 2 Kobes that are 24" deep. Not sure yet if they vent out the back though. CH0142 sqb and ch0342 sqb.

It finally feels like I am getting close. Thanks, Peke


 o
RE: back venting hoods

Found another one. Faber Maestrale- only 600 cfm, vents straight out the back, 25"depth, baffles.

Kobe's site said the ch0142 and 0342 are discontinued now.

Has anyone any reviews about Faber? Thanks, Peke

RE: back venting hoods

So is it impossible to get a 27" deep under cabinet hood with blowers? Or does 27" only come in island hoods and hoods that have to have blowers added?

I am guessing Wolf, Viking, Blue Star, etc have 27" deep but I would need to buy blowers, etc.

I thought about buying them separately, but I am not sure what sizes to buy or what to buy. Hood 42", liner ?", size blower, and anything I left out.

I am guessing it is much less expensive to buy it as all-in-one. If I get a hood over $1500.00 then I will be shorting myself on money for the counter top. I really want the counter top. I thought I could change the vent hood later on if I hated it.

RE: back venting hoods

Ok here is what I have found so far.

Faber Maestrale
Broan E6042T
Kobe CH0142 SQB
Kobe CH0142 SQB
Proline PLFW 832.42
Proline PLJW 101.4
Proline PLZW 697.42

What does anyone know about Cavalier-Euro, Windster, Air King, XO, Xtreme-Aire?


 o
RE: back venting hoods

I am narrowing it down, but still have questions.

I am putting the vent hood over a 36" blue star 6 burner.

24" deep Broan E6042T 42" wide, 1200 cfm. baffles,

24" deep Kobe CH0142SQB 42" wide, 1000 cfm. baffles

25" deep Faber Maestrale 42" wide 600 cfm

26 7/8" deep Dacor EH4218, 42" wide, 600 cfm, mesh filters

26 7/8" deep Dacor EH4212, 42" wide, 600 cfm, mesh

25 1/2" deep Dacor MH3618, 36" wide, 600 cfm mesh

25 1/2" deep Dacor MH4818 48" wide, 1200 cfm. mesh

So since I want to pull the BS out 3" from wall I need a 27" deep vent hood. Problem is they are only 600 cfm.

So how do I choose? The higher cfm, the deepest?

There will be cabinets beside the vent hood. Plus I really wanted baffles, not the mesh that the Dacor has. Can those be changed to baffles?

I am leaning towards the Broan. Thanks, Peke

RE: back venting hoods

I forgot. All are rear venting and have blowers already.

RE: back venting hoods

I can report on my DW's LED hood lighting experiment. The hood is a Wolf Pro Island hood and has three light ports on the underside of the hood at the counter edge side. These ports are designed for 50W R-20 halogen flood lights.

DW obtained some 7W R-20-like LED lights. They are a bit longer than regular R-20s, so the lower edge of their bezels peeks out from each port. The LED's luminous intensity on axis is higher than the halogens. They probably have higher luminous intensity over over most of their beamwidth. However, they are closer to spot lights in their pattern, and leave significant portions of the cooktop less well illuminated than the halogens do.

Although defined as warm white, they are a higher color temperature (whiter) than the halogens.

A positive aspect of the LEDs is that they won't set one's hair on fire from standing under them cooking. What they need is greater dispersion.

The cooktop is induction so the LEDs will not see high temperatures in our environment.

If I could add two more light ports canted toward their opposite side of the cooktop, light fill would be much better.

In the Wolf, the light switch positions are low/off/high. The underlying circuit is a mere diode, so the halogens get half-wave rectified power on low. As it happens, the LED lights power must be half wave rectified, but with the opposite polarity, so on "low" they are completely off. To fix this would require some re-engineering of Wolf's control circuitry.

"24" deep Broan E6042T 42" wide, 1200 cfm. baffles"

The Broan 24" E6036S 600 cfm with baffles has an internal blower. As yourself, I plan a dedicated exterior blower (Broan part E60E36SS).

Is that what the Broan E6042T 42" wide includes? Fairly popular vent hood for pro ranges as I understand it. I'd probably go with wider than range, counters on side, as deep as quality item allows in your budget, and more powerful cfms so effluent is quickly dealt with and generated blower fan noise may be less.

I saw the Best by Broan 24" WP29M364SB (add 900 or 1200 ext blower) the other day up above a pro range. It was nice. I want to find out the SS gauge, nickle/chromium content and finish on Broan models myself before putting out the money.

As to whether baffles can replace mesh filters, I doubt it but others may know better.

RE: back venting hoods

Kaseki, the Broan dimmer is the same: on, half, off. I thought the diode was an elegant solution (for incandescent) -- can't get much cheaper than that.


 o
RE: back venting hoods

kaseki, Thanks for your insightful post on LED in vent hoods. It's wonderful your daughter has you to help and provide such insight. Thank you for sharing the same here on GW forums too.


 o
RE: back venting hoods

So...which would be the best one? Not as wide but more cfm or wider with less cfm?

Peke


 o
RE: back venting hoods

Peke, my 2 cents (just my gut) is higher cfm (to pull the effluent hopefully faster before it disperses laterally) less width (but of course at least to size of your Blue Star range. And snug those lateral cabinets as close as Blue Star install specs allow.
Have you checked with your city/county permit office for local regulations: height counter to hood, maximum cfm if code dictates, any mua requirements?

Are you going to install Broan's make up air (mua) damper or like kind if you get a high cfm one. It's not overly expensive and is a consideration.


 o
RE: back venting hoods

Sorry I should have said not as deep but more cfm. I will definitely get a 42" with my 36" rangetop. I just will not be able to get my 27" deep hood. I am thinking about pulling the hood away from the wall 3" and adding a SS filler/backsplash if I can find someone to make it.

I think I will go with the Broan with higher cfm. Thanks to everyone for the help.

Now I am on to the next crisis! Paint that doesn't turn yellow, peach, or pink on my walls! LOL

Peke


 o
RE: back venting hoods

Baffles: Mesh can work more or less as well as baffles so long as they are kept clean. However, they are usually mounted flush with the aperture opening, so it is easier to spill effluent past the edges of the hood. Note that only the mesh area counts as aperture in this case.

Baffles have the advantage of working when greasy, and due to how they are usually mounted, baffle hoods have some capture volume below the baffles that helps.

Pulling: The upward or from the edge inward air velocity at a hood rapidly drops with distance from the hood, so the effect of more cfm on capturing effluent that would otherwise miss the hood aperture is quite modest up to very high intake noise levels. Higher cfm may help capture effluent hitting the mesh filter frames. Once past the filter, containment for either filter type will be good so long as the air velocity is at least 3 ft/s.

RE: back venting hoods

Thanks to all. The Broan is ordered. Peke

RE: back venting hoods

Here is the Broan E6042T with up AND back venting. In the picture you can only see the baffles. They seem to be good quality. Two rectangles to punch out for the 2 blowers.

No Broan label on it. Peke


 o
RE: back venting hoods

This is the back of the hood. The 2 rectangles punch out to vent upwards, but there are 2 on the bottom as well so you can vent straight out back.

Peke


 o
RE: back venting hoods

Nice looking Broan hood, Peke! Are you doing your own install? Thanks for the pictures too.


 o
RE: back venting hoods

It was the best price for one that size. We have beenn looking for a long time and I thought it might help someone else who was looking for a rear venting hood.

No, wish we could install it and save money. As my husband says, "hubby don't do electic".

Peke


 o
RE: back venting hoods

Besides "electric," many of these hoods are heavy, and will require some muscle to hold them in place while attaching them to ceiling joists or wall studs. For larger hoods (and before lower cabinetry is in), a sheetrock lift may prove useful. Alternatively, depending on weight, jury-rigged schemes for temporarily supporting the unit can allow two normal people to do the install.

kas


 o
RE: back venting hoods

I have the Broan Elite as well and I vent it directly out the back. I really like this hood...


 o
RE: back venting hoods

That's the top of the hood, not the back. ;-)

The electric part of the install is simple. Physically getting it into place and connecting the vent is the harder part.
