He took one look at the AQ3 and said it wasn't appropriate. For one thing, Bosch mandates that the exhaust be constructed of 4" stainless steel. This equipment is 3" and the main exhaust vent pipe is aluminum. In some climates, the fumes react with moisture in the air and form acid (think acid rain). The acid and water accumulate in this corrugated pipe and drip back into the unit. This means that the main vent will fail, and then cause the water heater to fail.Unless you live in the high desert, don't use this installation kit. I'm returning mine. ### ⭐⭐⭐⭐ 4.0 out of 5 stars got the jobe done *by D***Y on Reviewed in the United States on October 30, 2009* This is a great product that makes your work easier. Make sure you make holes in wall first and install it then mount your hot water heater.
