Thank you for your question. No this product is not FEMA approved as it is not something that would apply for this product.
Thomas, I would like to answer your question but there is not enough information for me to realize what you are trying to accomplish. What hole are you referring to. The ventilation access kit comes with the access screen panel and frame.
You can have covers cut somewhere and drill some holes and screw sheet metal screws on the outside of the unit yourself; I would.
This assembly is made to be installed when the house foundation is being built. If you do not have an access crawl entry, you will need to cut the foundation to install one of these.
