Rinnai makes exterior units. Do they freeze in the winter in Kansas City, MO?

Rinnai makes both interior units (which are sealed combustion and vented outdoors) and exterior units. All Rinnai units are designed to operate properly to outdoor temperatures of minus 30° F. Exterior units will not freeze even well below zero as long as they have electrical power and gas. However, the water connections to an exterior unit must be properly protected from cold conditions by the installer to prevent these water lines from freezing.
