When you are working in the kitchen, there is a moment where you realize that your kitchen exhaust fans just are not doing the job that they are meant to do. The whole purpose of having the exhaust fans is so that as you are cooking up numerous dishes to please the guests that you have waiting, it will suck up all the smoke and invisible debris, as well as the heat, that rises up and away from your food. By turning on the fans, all of these problems are quickly sucked up and shoot into the chimney to be dispersed into the air outside. So if you find that your fans just aren’t doing the job that they should, you may find that it is time to install your own additional exhaust fans.

Step 1 – Make Your Measurements

The problem from the increase in heat and smoke is often going to be doubled if you are dealing with a stove top island. This of course is an island feature that is within the kitchen that actually has a stove built into the surface of it. Above this feature, there is going to be an additional exhaust system that will suck away the heat produced by this. Typically these are made of metal. It is within this unit that you are going to make your measurements. As with all projects, be sure to make your measurements twice and then cut once.

Step 2 – Measure Your Exhaust Fan

You need to know the size of the fan that you bought for your exhaust system. Typically the fan units will be slightly larger than they need to be, in order to ensure that you can securely install them into the exhaust system. Measure how big the base unit is, so that you can cut a hole that is large enough to hold the fan, but not so big that the whole unit is simply going to fall through the hole. Be sure that the measurements are about 2 inches shorter in diameter than the actual unit itself.

Step 3 – Make Your Cuts

Now you are going to cut a whole into exhaust system. Be sure to do this carefully as metal has a tendency to flake and splinter when it is being cut. Once you have the hole cut out, you are now ready to install the fan itself.

Step 4 – Install the Fan

Now you can take the fan unit and install it into the exhaust system. Once you have ensured that the fan is going to fit snugly, you can use roofing caulk to go around the outside of the rim of the fan. Don’t be afraid of how much you use. You can never have too much. The only real downfall is that if you ever choose to remove the unit, you are going to have a heck of time doing so. However, if you don’t use enough, you are going to end up with a lot more work.

Step 5 - Check the Electrical Circuitry

Use the manufacturer’s guide to ensure that you install the circuitry properly. You are going to want to have the wires connect to a power switch, so that you can turn the fan on and actually have it function properly. 

Step 6 – Leave it Alone

The important thing now is to allow the exhaust fan time to sit and allow the caulk to dry and harden. This will ensure that you don’t start knocking the unit around on accident when you are cooking and then knocking the fan out of place and creating a very large mess that may require a large amount of money to repair.
