Product review (5 stars): Excellent kit for maximum control of the airflow through the GE GeoSpring water heater.
This kit provides the ability to install a GE GeoSpring water heater in a small water heater closet as long as the vents can be run to larger spaces. Alternatively, the kit can enable the water heater to draw air from and exhaust cool dry air to specific spaces. I draw from the cooler 5 ft elevation during summer and from the warmer 8 foot elevation in winter to control the temperature of the output air into our living space for maximum comfort. Two 8-inch hose clamps are included with the kit and all screws needed. The intake side includes a dust screen which replaces the original one.  The output hood is installed using the included self-tapping screws which requires a drill to install. The head size of the self-tapping screws is the same as the hex size of common drill driver bits (1/4 inch), so a drill driver extension works well to drive them.
