We are hearing here repeatedly and on other web sites as well: These vent systems have perpetual problems. First, they suck serious heat away from the gas burners. Secondly, they are located too low to affectively vent the tops of pans and pots.
The built in down draft vents in the middle of stoves and tops are worse then the pop ups. ie. like Jenn-air.
So what if we did this on new or remodeled kitchen islands:
1) build in a " box" behind the cook top or stove. The box would be fire proof, wide enough for the pop up fan and say, 8" above the counter.
2) the eating space around the island would also be raised 8" above the counter top.
3) the pop up is installed in the box.
Now allowing 2" in height for the burner and 9" for the pop up vent, when the fan comes up, it is about 6" to 15" above the burner and the bottom any pan or pot.
There should be two benefits: Better exhaust pattern above the pot or pan and no sucking the heat directly from the burner.
Whatdoyathink???? Will this work? It is my own design so I'd appreciate your ideas and feedback.
I'm getting ready to build the island and I just might do this.
