A question on Venting....

18 years ago

We are doing a kithcen remodel and plan on a 36" pro-style range, most likely Thermador. Our problem is the range will be against an inside wall and that is causing some issues with venting. The back of the wall the range will set against is a staircase leading to our basement. Question is could we just vent the air from the range vent into the basement? I don't like the idea of downdraft or recirc. so i thought this may work. The house is old and budget is an issue, i don't want to into too much with the vent being as cost is already more than we wanted to remodel.

Thanks, for input

The short answer is no - you can't vent into an attic or basement - it's dangerous and probably illegal. You can probably run the duct throught the basement but it needs to vent outside.

Going down is also fighting the natural rise of hot air.

Our bent is on an inside wall and we did a 90 turn to run the duct across and out the far side. The duct runs between the joists. We were able to get a 10 inch duct, but not a 14 inch silencer.

My mom is doing a similar set up. I am running an 8 inch round duct into the ceiling, adding a right angle and running it across over the kitchen in the joist space to the outside wall. Luckily, the joists are going the right direction or else we would be moving the range.

If your joists are oriented correctly, this would be an option. Just make sure you have accounted for all the added turns and length when you calculate how many cfms you need. Usually, the hood specs include a table with allowances for turns and langth. Good luck! I am doing this Tues so if you need a picture, let me know.

My old GE Profile electric glass cooktop had a downdraft vent, 6" duct, that ran through my basement to an outside wall. It was ineffective.

In my remodel, I purchased a Wolf rangetop. My GC tried to convince me that I should reuse my downdraft and existing duct. I said no.

My thinking was why spend the $$$ for a great gas rangetop and not be able to fully utilize it because you're worried about smoke, grease and smells.

Mine is also on an interior wall. The 10" duct takes a 90 degree turn from the hood runs through the top of my double oven cabinet, then into the top of the hallway coat closet, another 90 degree turn, up through the 2nd fl linen closet to attic and roof. The duct is sheetrocked in and not unsightly.

I've got a Broan Elite 1200 cfm external blower mounted on the roof. I went with higher cfm's than needed for my rangetop due to the double 90 degree turns and length of duct run. It's very quiet and effective.

The Broan technical support folks helped me come up with this solution. If going up just won't work, start contacting some of the ventilation manufacturers your considering for ideas on how many cfm's, size of duct, etc... you will need to accommodate the turns and distance your duct will run through your basement. As Weissman said, it has to vent outside from the basement.
