I have an old vent, about 6-8 inches in diameter, in my ranch style brick home that used to be for my stove. We have done away with the stove and no longer need the vent. The hole and vent is outside and leading into our unfinished basement so it would be easy to run an electrical outlet (GFI) where the hole is to where we are going to put a fountain with some landscape design.
Can I place the electrical outlet in the hole and cement around the outlet with the electrical wire into the basement? Do I put CCA treated wood or an aluminum piece of metal inside behind the cemented hole to support the concrete inside the house?
