Duct Offset Installation: How to Install a Range Hood with an Uncentered Duct
You have purchased your new range hood and now it is time to install it. If you run into an offset ducting problem, there are a few options that can help resolve the issue.
If the duct in your home is not centered, you will most likely need to use adjustable elbows to make a turn and connect the range hood to the ducting. Once that turn is made, the ducting will need to be covered.
It is likely that since a turn is being made, the width of the ducting will be larger than most standard chimney covers. Most chimney style range hoods have chimney covers that are 11-13" wide. If the duct takes up more space than the average chimeny covers, there are a few solutions:
Use an Under-Cabinet range hood with cabinets. If an under-cabinet range hood is used, there is more room for the ducting to turn inside the cabinet. A great way to conceal ducting is inside a cabinet.
Wide Chimney Cover
Use a range hood that has a wide chimney cover. Range hoods such as our Tofino model have an option to purchase a separate stainless steel cover that spans the entire width of the hood. If your ducting must be off-set, this may be the solution for you.
Create a drywall box and install the duct turn inside in order to center it. Depending on the height of the ceiling, this method may require custom cutting of the range hood chimney covers. For example, if the ceiling height is 8 feet and a drywall box is created, this will create a lower ceiling for the range hood and chimney cover. All range hoods are made to work with standard 8 foot or 9 foot ceilings. Any range hood that is installed with a ceiling lower than 8 feet, will require custom cutting, which we offer as well.
