OTR (over the range) microwave - vented inside or out?
We just bought a Kenmore OTR microwave, which can either be vented to the
outside (ceiling or wall) or vented inside (and use a charcoal filter). It is a new install (no OTR present before) Which is the better of the two? 1. I hear that with inside venting method, you don't have to worry about wind blowing and making noise, nor about the hassle of running the vent to the outside air (either wall or ceiling). Sounds a lot simpler 2. You would think that the outside method would be more effective in removing smoke and water vapour from cooking. You would also not have to worry about replacing the charcoal filter. Comments / tips / suggestions / ideas / advice? Howie |

Outside it always better for eliminating odors, excess heat. Depends on how much is involved in venting outside. |

Vented in is completely useless. I really miss having an outside vent.

From there, can I run a flexible vinyl tubing to the roof? I am about 35" from an exterior wall. Which is best? (roof or wall)... Howie |

Howie If you fry foods a lot or create a lot of smoke in cooking, you may prefer the outside vent. But remember, the hood will be taking all of the "conditioned, hot or cool" air out of the house and venting it outside. After the oil embargo of the early '70s, you couldn't get a permit for gas in new construction in some states (Wisconsin for one) if you vented your hood outside. Too wasteful. In addition, the dampers on these things don't stop much cold air from falling into the house from outside. We just switched from a non vented hood to a non vented micro hood. We've been happy not venting but we don't fry much. And it would have been easy for me to vent right out the back through an outside wall. Tom. |

Howie Don't EVER use flexible vinyl duct for a kitchen vent, it will be a mess (not to mention that it probably won't be to code). Think of all those nooks and crannies just waiting to catch the greasy moist hot air that will be going up that tube. Use solid metal duct all the way to the roof, square or round makes no difference. IMHO, if the stove isn't on the outside wall, then go to the roof and keep the turns as few as possible. To answer your question, yeah, you can do what you think. You may need a duct man to custom make some pieces, but they aren't that expensive. -- Grandpa Koca - SAHD for 6 - Keeper of the Perpetual Kindergarten My opinion is neither copyrighted nor trademarked.

No matter what, you wouldn't want to circulate filtered(?) air in the kitchen. No range hood with vent now? Tony |

Howie To pass code in most areas hood venting needs to be done in metal pipe, no way I would run it in vinyl flex duct! Think range fire, with the fan running. You just helped fan the flames and spread them into the attic! If you can not vent it outside in metal duct, then don't bother! Greg |

Didn't know you fried stuff in a microwave and if you get smoke in a microwave you are doing something wrong. Yeah I know there are special dishes for bacon, but still..... I think you must have missed the part about the microwave. Otherwise I agree, the regular hood for the main range should preferably be a vented. |

Sure, you will have to live with the popcorn smell for a couple of hours longer, but you'll save all that unnecessary construction. -- Bill |

----cut----
To run it outside, I'll have to run the venting up into the about cabinet, then into an inside an interior wall cavity about 24" (can I do this?) to the ceiling. From there, can I run a flexible vinyl tubing to the roof? I am about 35" from an exterior wall. Which is best? (roof or wall)... Howie Mine vents up into the upper cabinet and then through the wall inside the upper cabinet. Less than 24 inches total. Check the directions for the maximum length of exhaust for you unit. Flex is out, not approved for kitchen exhaust. Remember this is fairly low pressure exhaust. Any obstructions/corrugations in the pipe will just collect grease. I once used a bathroom that had carbon filter. Yikes never worked. I do not understand why anyone would want to recycle hot/greasy/humid air. Look at the filter, do you really think that it is going to filter much? For that matter the exhaust on mine does not really work except for the rear burners. Makes more noise that anything else. |

I lived without sex for about 13 years, but I have no intention of becoming celibate again. I'd base my decision on how difficult it is to put the vent outside. Mine was fairly easy so I did it. If it was major reconstruction, I'd forgo it. There are time I'm really glad I have it but no, it is not used every day. |

The venting is for the stovetop beneath the microwave, not the microwave oven itself. OK. I was thinking under the counter, guess OTR means over the range. Not to be too flippant but damn, that's got to be a stupid idea, put your electronic stuff right above steam, smoke, and what all. |

Howie That is the way it is done in many houses when the cabinet goes to the ceiling. No much room left in the cabinet though. Climb up there and put a can where the pipe would go to see if it would be obvious. How much room between the cabinet top and the ceiling? With crown molding and the pipe near the wall, it would likely not be too noticeable. In any case you put some type of decorative wood around the pipe. |

I think that having no range hood at all lets a lot of steam and oil go all over into the inside of the house, coating walls, ceilings, carpets, furniture, etc. I HAVE used a microwave for years without exterior venting, but don't cook in it long enough to make smoke. (Except for the time I set the bag of popcorn on fire.) I don't like a microwave above a range because that is where all the steam and smoke from the range goes, and it is a short time until the microwave is gunky, even with an exterior vent. Just MHO, YMMV Steve |

Right, but not everyone has the counter space to spare so this is a way to have the microwave and not lose 20" or counter space. Not my first choice either, but it is the only practical choice in my house. |
