   Allegedly, the micro's exhaust is too small for the stove, not enough cfm's.

   You might check the Height of micro above the range.  The allowed clearance is higher than conventional ranges I think.

   If you're lucky, maybe she got a small one.

   and don't offer to help move it in.

   it's all according to what range she bought.  some have burners that do 18,000 BTU like a real commercial, while others just look commercial but run at 12,000 BTU. 

   If the HO is going to really cook, and the range is putting out 18,000 BTU per burner, she's going to need a real exhaust and 900 cfm will save a lot of headaches, like when she's making bacon and the smoke detectors start going off. 

   On the other hand, a lot of people put in these ranges for the look and barely use them, and if they do, never crank them up anyway.  Still, a minimum 650 cfm fan is needed just in case they mistakenly turn on a burner and cook something.

   You don't say what size range she has, but assuming it's only a 36" she's going to need at least a 650 cfm vent hood.  900 cfm would be even better, especially if she has a grill burner.  It's usually recommended to go with a 42" hood with a 36" range.  The hood has to be mounted 27-30" above the range and it should extend out 24-27".

   Speaking of exhaust hoods, I'm installing a 650 CFM Miele hood over our cooktop which is to be installed later this month. My plumber was over the other day running the gas lines and he mentioned that I might want to keep an eye on things as this kind of ventilation could effect my hot water heater and furnace in the basement.  Some of you were mentioning larger 900 CFM units, is this not something to consider?

   According to him, depending on how efficient or 'tight' a houses is, this vent hood could cause a back draft situtation (not like the cheesy movie)  or negative pressure.  It could also be compounded if I was running the gas dryer or gas fireplace at the same time.  I might be looking at an air exchange unit if I run into problems. 

   Something to think about.

   My expierence is that it is not feasable to install a microwave over a Viking gas range.  The requied clearence would mean that the micro was too high to realistically use.  The ventilation requirement is also an issue.

   Having read the manual for a similar (but in my biased opinion better) stove, I wonder how anyone could think of installing a microwave over a prosumer appliance. There is a lot of concentrated heat to deal with, if all 4-6-8-whatever burners are firing.

   IMO, your best bet is to install a hood that is 6" wider than the appliance underneath it and that has significant overhang. That way you'll capture most of the fumes and the curtain effect that a effective range hood will create will be quie effective at keeping the fumes out of the kitchen, even on low speed.

   Some hoods also offer variable-speed motor control based on what the hood preceives as the venting need. Could be an interesting option.

   The points raised about tight homes having issues with high-CFM hoods is also spot-on. I had the AC guy install a duct and a motorized damper that opens a 6" exterior duct into the main AC return every time the hood comes on. Between that and the two HRVs we'll hopefully be OK most of the time.

   Lastly, I wonder to what extent the 150CFM/burner requirement was the simplest way for prosumer appliance manufacturers to cover their liabilities, because 150CFM per burner (in the 15kBTU/hr) range is what I believe the commercial code calls for. Yet, few of us will cook for 12 or more hours per day.

   Would'nt put a micro over the range (except in a motor home maybee).
   Do your client a favor (if feasible) whatever CFM you come up with, install a remote blower, done it many times, as a "first course of action". She'll praise you everytime she turns on the blower, (and everyone will hear her better).

   Good luck

   WE have the Viking range/hood, and even the Viking Hood doesn't suck enough. I WOULD NOT use a microwave fan. The stove is very nice, though. Darn hard to clean.
