Just got off the phone with a guy who was grandfathered in as an HVAC contractor.
He did a job that was redflgged by the inspector for not having a flue liner for the water heater in a clay lined chimney, also he put a union inside the furnace cabnit, at the gas valve. And 2 small issues outside.
He said that he's never seen a code book, and that having a union inside the furnace is just fine, the inspector is picking on him. Here the book says no unions inside the cabnit.
I can't believe he thinks that,that should be fine.
He wants the union there so if he ever has to change the valve he only has to loosen a small portion of the gas line.
The flue is an 8" clay tile lined chimney, It used to have the old furnace and the water heater, now it's just the water heater. New 90% unit vents side wall.
So now he's mad, well maybe if he had stayed awake at the continuing education classes, or even knew the codes to start with. He would have done a better job.
