Decide on a good location for your ventilation system. A basement is usually a good location if you have one. Place the system near a 120-volt electrical outlet.
Install a support system for the ventilator. However, if it is placed over a cement or other sturdy surface you do not need to worry about this step.
Use a large saw to cut holes through the outside wall for the exhaust ducts.
Run this ductwork to a central location, so air can be exhausted into your home. Otherwise, you may fasten it to the intake on your central heating appliance.
Attach drain tubing to the ventilator and run it to the closest floor drain.
Connect the ventilator to the nearby 120-volt outlet. If there is no outlet close to where you installed the ventilator, you could call a professional electrician to complete this step for you.
