Stove and Microwave venting

[RALPH WERNETT]

I would like to vent both a microwave and a range. I planed on running two 6" round vents side by side (both microwave and stove are on the same wall) and have them connected with a "y" connector just before it goes though the outer wall with a vent plate. Both units have dampers on them so there shouldn't be any back flow. I figure I would ask just in case I'm missing something.
Thank you.

Aren't most microwave vents meant for over-the-range installation and the vent fan is for the range, not the microwave itself? That is, I don't see any reason to vent the microwave at all.

I've never seen a microwave vented, that includes a couple of convention microwaves. If you doing an over range in a location other than over the range and want to vent it to draw air from the room that can be done also.

Ranges do not have a built in vent fan.

Unless it's a downdraft like Jen-air

you are correct, we have one and it vents out through the floor. The vent is on the same surface as the burners.

We have a Jenn-Aire cook top with the down draft, never seen one of their ranges with the down draft but into it. I've also done the Thermodore raising vents, but only on a cooktop.

They make a downdraft range just like a cooktop
Not really popular
The last time I've seen one was about 8-10 years ago

They still make them.  Their reliability is pretty spotty.  I've had to deal with two different kitchens this year that had them.  One customer had the Jenn-Aire range in an island, so the new island cabinetry was a little deeper, to accommodate a pop-up downdraft and cooktop.  The other client chose to replace the existing one with a brand new gas version.  In both cases I tried to convince the clients to go with designs that would allow for less expensive appliances, but I must not have made a convincing enough case.

We Have a GE Profile range with a matching GE Profile Microwave mounted above it.  The Microwave includes a fan for venting fumes from the cook top.  In addition, when you turn the microwave on a small motor opens a vent directly above the microwave door and a fan vents anything coming from the microwave.

Every one I've ever seen with a range was a separate piece that went behind the range. I'm sure I have not seen them all. 

There is a Thermadore raise up behind this cooktop.

$3500 list for a Whirlpool range with reduced oven capacity.  That's more than the new Samsung Pro induction cooktop / two-zone oven I covet.  I guess it's one solution to a problem, though.

This question doesn't even make sense. The main purpose of the fan unit in the over the range nuker isn't to vent the microwave but to vent the range. If you are going to have an inset nuker at a cabinet there isn't much point to venting it. If the nuker isn't over the range then use a hood.

Why are you venting a microwave?  My Sharp has been working for 24 years.  It is not vented but I did allow one inch on each side and three or four above the unit.  The biggest problem I had saw that it was too deep and stuck out beyond the cabinets.  I cured that by notching out the 6" studs and having a stainless enclosure made for the unit to close in the rear.  My wife uses the space above to store her serving trays.

 

[jbasen]

The only microwaves I've seen that include venting are those that are built-in above a range and include the venting for the cook top.  On these microwaves there can be a feature where the microwave vents itself into the vent line to help remove steam produced while the microwave is running.  Just an added feature when the vent line is right there anyway.

I think that the OP has a microwave/hood combination that he wants to use over his Jenn-air downdraft range
I guess having an additional vent helps
So to answer his question about connecting the 2 ducts,it should be OK
But I never seen this before

 

[WastedP]

What?  He wants to put a unit that sucks air up above a unit that sucks air down?  It sounds like ventilation tug-of-war.

Thank you for all your replies, been away form the internet for a while... The ideal is having the microwave in a different location than the range hood, but didn't want to run two outside vents.  The MW was only to vent itself, nothing under it...  I did decide not to vent the MW but only the range hood...
Thanks again for the feed back.
