Problems venting Imperial range hood
Comments (4)[I feel like I need to parse that one paragraph blob in a word processing app just to decode its content. Only having read it thrice, I'll limit my comments for now to hood construction and general requirements.] In order to obtain relatively equal flow through the filter area, whether baffles or mesh, there has to either be some height above the baffles (probably commensurate with their airfoil length), or similarly above the mesh (narrow dimension), or the mesh has to be so restrictive that it chokes the flow equally at all points (not good). So of all the noted configurations that weren't already rejected by the OP, I would vote for narrowing her consideration to whichever ones provide enough height for the selected filter type and dimensions. Baffles have advantages over mesh filters, but both can filter if the meshes are kept clean. Less tortuous duct paths are preferred over more tortuous paths. Full power actual flow rate (CFM) should be roughly 90 cfm/sq. foot of hood aperture, if possible. A rated capability of the blower of 1.5x that above should accommodate pressure losses in ducting, hood, filters, transitions, and MUA restrictions. Duct area should allow the air velocity in the duct at full power (90 cfm/sq. ft times the aperture area in square feet divided by the duct area in square feet) to be between 1000 and 2000 feet per minute. Aim toward the lower value if all the ducting remains warm in winter, or the higher value if passing through a cold attic. kas...See MoreVent hood height problem
Comments (3)After discussing it with my husband we have decided to take out the soffit above the stove, exchange the 30" in hood for the 36" one, and mount it at 30" above cook top and have the chimney extend to ceiling as I had originally intended. Thanks for your help guys!...See MoreProblem with venting Wolf Hood - PW482418R. Help!
Comments (5)Thanks! The venting for the hood and plumbing for the fridge are really the only things holding us up from getting appliances so we hope it can be sorted out soon! Calling Wolf directly is a good idea. We'll try that. We had to get an attorney involved after we received the letter from the GC's attorney. I can't post the details at this point really (at least not under this name), but you wouldn't believe it. Saying that the guys is a piece of work is an understatement. There is nothing I would like more than to post every detail but probably sensible to keep quiet for a bit and see what happens. If I never hear his name again it will be too soon. At this point he disgusts me at every level....See MoreHelp with vent hood problem
Comments (15)partigal, I'm not sure it matters since switching to it would require a new cabinet at this point and I don't know that we can/will do that. But I have owned this hood previously and I was able to turn the lights on and off separately. So unless that has changed with a new model, yes it does. Additionally the lights in the imperial do aim straight down, not forward. Again, not sure it matters for me at this point though. I have actually never before seen a vent hood that you couldn't turn the lights off and on separately from the vent and I have also never before seen a hood that has lights aimed forward. And I have lived in a lot of houses. So it seems likely to me that almost any hood would be an improvement in this regard....See Moremississippirose
