Just about a year into my home and have decided to start doing some repairs/decorating/renos etc. and moved the piano that came with the house to find an old stove pipe covered by a doilie by the former owner. The pipe has been filled with plaster and it sticks about 1/4" out from the wall and is very unsightly. My wife and I are planning to either paint or wallpaper the room and this needs to go.
It looks to be a galvanized pipe and has a cracked plug of plaster that is sort of concave inside of it. The chimney is only used for venting the oil furnace.
First, is this safe?
Secondly, what is the best course of action to level it with the wall and cover it over?
I was planning on knocking a bit of the plaster out with a chisel until it is behind the line of the wall and either folding in or cutting the protruding pipe inside and then patching the wall.
