I ran across this new construction direct vent water heater in a 7’ high crawl space and the installation is bothering me because the drain pan is setting on a dirt “floor”. I have researched today and cannot find a specific source of information stating it CANNOT be on a dirt floor in a crawl space?? What if a water pipe breaks and washes out the dirt underneath it? What about the pipes not being insulated?
Please share with me your wisdom before I complete the report!!
