Range hoods are common in the sense that the majority of kitchens have them, but what many people do not have in their homes are range hoods that vent the air outside of the house as opposed to simply filtering the air and recirculating it throughout the kitchen. Air ventilation is very important in any kitchen, primarily because of the grease, smoke and debris that crowds the air as a result of cooking and baking. Without proper ventilation, these air pathogens may eventually lead to health problems or food borne illness, so proper ventilation from the start is a necessity.
If you already have duct work built into your home, installing your new range hood should be a pretty simple process. On the other hand, if you were previously using a ductless range hood and are looking into switching to a vented range hood that will actually deposit the contaminated air to the outside of the house, you may need some additional construction and design work to make sure that everything is properly set up and ready to go.
Before beginning the ductwork and vent hood installation process, make sure to remove any unnecessary body parts from the hood such as the filter, fan, light housing and electrical work
Lift the hood to its permanent location above the range and outline the section that will be knocked out for the duct with a pen or pencil. The knock-out can also be made through the top for wall mounted vent hoods.
Saw out the rectangular piece from the wall where you made the outline, and drill a hole next to this box for the electrical line.
Repeat the same process for cutting a rectangular hole on the outside of the house. If possible, remove the block from the outside wall from inside of the house to achieve better alignment with the first hole.
You can create a mounting plate by aligning a piece of PVC plate to the hole against the inside of the kitchen. You can affix the plate with screws and a silicone adhesive as necessary.
If possible, get someone to help you hold the vent hood in place as you feed the cable through slot next to the knockout hole, and clamp the range hood into its permanent position against the wall and above the range.
Now it’s time to install your duct work. You can do this by starting with the rectangular hole on the outside of the house. Slide the exterior vent cap into the hole and secure with screws. As necessary, apply a silicone sealant around the edges of the cap to ensure no moisture can seep through on wet or rainy days.
On the inside of the wall, ensure electrical function before sealing off the duct work. Use a wire not to conceal the electrical wiring, and attach the vertical cover to hide the ductwork and finish installation.
Finally, install the body parts back into the range hood and enjoy a cleaner, more breathable kitchen space!
Have you installed a range hood and/or ductwork in your home? If so, how did it go? Did you encounter any issues, or do you have any suggestions for others who are looking to do a self-manned installation?
