I have been told recently by a potential buyer of my home that due to the gas hot water heater in my utility room, with electric washer and dryer, that I need separate venting to bring it up to code. The room has two outside windows, and the door opens into my dining room. I live in Texas.
My own contractor who remodeled this old home 3 years ago mentioned nothing of this. What type of venting is he speaking of?
