Thank you. it Goes without saying that functionality is important. That’s why I am specific and aware that most 48” stove offer the functions I want. Reliability is important. I was not aware that I needed a make up air unit for the actual range. i had been looking at appropriate exhaust systems. I’m hoping not to spend $20000. Do you have recommendations or experience with these type of stoves?

anything "good' will be expensive. the make up air part is also important and will be more than you would imagine as you are not just buying a small vent hood.

find a local dealer that sells and services what they sell - not always the case to do both. with that amount of expense you want to make sure that when it breaks (they all do) that you can get it repaired quickly

my only dive - avoid those really good looking Italian units

Thank you. I have heard to avoid the Italian ones. So not sure where that leaves me.

you may want to determine if you even need a 48 instead of just wanting it. that really is a lot of firepower (in every sense of the word). Maybe a combination of 30 or 36 range top with a collection of steam ovens and wall ovens would give you really need

It’s for the location and double ovens. We don’t have space for a wall oven. You’re right, I don’t need a grill. Blue star and Wolf are definite contenders. Do you think dual-fuel is important. I didn’t until reading up on it.

I mean the 48” requirement is only because of the double ovens.

I've had two 48" ranges, one a DCS and the other a Wolf. I prefer the dual fuel Wolf, but maybe it worked better because it was newer than the DCS. I would not do this set up again, because for my style of cooking, the ovens in a 48" range are never the right size. One is too big and the other is too small. I also have a 24" Miele CSO XXL and that is the oven that I use 90% of the time. Next time around I would do a 36" range with a 24" Miele CSO XXL or a 36" cooktop with a 24" Miele CSO XXL (with trim) above a Miele 30" oven.

Although review of many hood and make-up air (MUA) threads here is recommended, here is a brief summary of suggested requirements.

Use 90 ft/min as a hood entry air velocity goal (without a cooktop grill). For a 4.5 x 2 ft nominal hood aperture, this corresponds to 810 CFM. The blower needed will be rated around 1200 CFM, because it will be operated with pressure losses, not hanging in the air outside.

10-inch duct will be appropriate. We can discuss noise mitigation when you get on-board with the overall system requirements.

Code requirements for MUA vary with locale; for safety, you will want to supply 810 CFM of MUA with low pressure drop relative to outside. The definition of 'low' depends on what combustion appliances (hot water heater, for example) you have and whether they have their own MUA. When this is known, either relatively inexpensive passive MUA or more expensive active (fan blown) MUA can be selected. Most code authorities will not determine MUA effectiveness, but you are advised to achieve it anyway. In colder areas, MUA heating may be required, by code or by cold tolerance.
