When a house has work done and it looks good first glance, have a look around. See if things look right everywhere. And remember, angling is for fishing, not kitchen vents.
Around the back of this house, which added a garage and new James Hardie siding, I noticed the odd kitchen vent.
It had to be shifted somewhat to accommodate that new garage.
Kitchen vent openings are large, necessarily, because they need to move a lot of air.
That is especially important when cooking is done with gas.
Any build up inside of the wrong gases can be a bad thing!
Also, the flaps on those vents work with a spring and gravity. The force of the air opens the flap, and when the fan is turned off the flap is closed by the spring so animalia do not get inside.
And it's not a great idea to blow the exhausted air directly at a window, which might be open as the cooking is done. But that is just me...
From the ground I could see the vent wasn't looking right.
So I tested it, on high!
I noticed that air seemed to be drawn in on the one side, but was blowing out on the other.
That can indicate a clog, or that the flap is not opening properly.
Going back outside, this is what the flap looked like with the fan on high.
It isn't working. That's why the air is returning to blow down back onto the burners.
Either there is a clog, or the flap is stuck in some fashion and cannot open.
No matter what, angling the vent, and its flap, is not the best way to vent air, but this is what they were left with when the new garage roof abutted the house!
The vent itself has come somewhat askew from the framing they installed to accommodate it.
My recommendation: remodeling is good! But always have a look around. Look at everything too, because what you see is what you get!
