Hi all, I am clearly new to most of this but hope you all will be able to help me find my way. I was recently givin a wood stove and in my prep to get ready to install it I noticed that my damper opening is only 5 inches and the opening on the back of the stove where the liner will attach is 7 inches. Is it OK to force a 7 inch liner through the 5 inch opeing? Sorry in advance if this is a stupid question and thanks for the help!
