Not at all. I just happened to notice the setup of this combustion air source and it didn't look right to me so I recommended my clients get further evaluation to ensure it is proper. With both air sources being located at the bottom of the space, I figured it can't be right. When i called this as potentiall being incorrect, the builder went balistic and insisted everything in the home is correct but I had already found at least 5 other deficiencies that did not meet the code requirments and the city did in fact verify I was correct but this last issue seems to be eluding all of us as nobody will make a call if it is correct. Just curious if the setup is correct or not. I've also run into multiple problems in new construction in this area with missing fire walls in garages when bedrooms are located above them, electrical splices not in junction boxes, cross connections etc. My faith in the competency of the city codes inspectors has dwindled dramatically lately so I don't want to miss an important safety issue such as this.
