This not only created pressure drop issues throughout the kitchen, but led to excessive hot water use as well. Fenske explained why the restaurants were experiencing so many problems, and the words resonated.

"It planned to convert any problematic installations to Navien units, while standardizing on the NPE-240A for construction of all new restaurants going forward."
