Build a custom decorative box to cover your old range hood. Reorganize your kitchen, so you don’t need the extra space of an overhead cabinet and then cover the front and sides with wood that you can stain or paint as shown here. You’ll still have access to the vent controls by reaching underneath. And, the front ledge works as a spot for small fun or functional objects.
While these by-products may simply sound like nuisances, studies have shown that cooking without proper ventilation is one cause of poor indoor air quality that can negatively affect your health. That's why the International Residential Code and the U.S. Environmental Protection Agency strongly advise homeowners to install a vent hood to capture, filter, and then expel the fumes outside through a vent in an exterior wall or on the roof.
Venting the polluted air out of your house is always preferable to recirculating it. Recirculating fans use charcoal filters to clean the air and release it back into the house when ducting to the outside is impossible, as in many apartment buildings. When it's the only option, a recirculating hood is better than no ventilation at all, but this type should never be used with pro-style appliances.
If you prefer to install a passive makeup air duct rather than a powered makeup air unit, the duct must include a motorized damper that is wired to come on simultaneously with the range-hood fan. Broan sells motorized dampers for this purpose, and also provides detailed and useful installation instructions.
Concerning the reference to NFPA standards, I tried to pin down what GE was hinting at. I contacted Allan Fraser, a senior building specialist with NFPA. After hearing me read the relevant paragraph from the GE instruction booklet, Fraser said, “That is a bad reference. As far as makeup air for range hoods is concerned, NFPA doesn’t cover it. Frankly, it is not an issue on our radar screen.”
If your heart is set on a stainless hood, and feel a custom wood range hood would be mutually exclusive, consider the solution shown above! The stainless range hood is complemented by the enclosure overhead, which encases the duct work, resulting in a harmonious and fitting combination.
GE went out of its way to advise range-hood installers of the best way to install a water heater or a furnace — that is, by following ASHRAE standards. Why didn’t GE bother to tell range-hood installers that ASHRAE also has something to say about the best way to install a range hood?
