All Rinnai interior units utilize an exclusive cool-to-the-touch vent system that is sealed combustion
and requires only one penetration through the roof or sidewall. Rinnai interior units can mount almost
anywhere and can have a vent up to 41 feet long. They are designed to operate at outdoor temperatures
as low as -30° F.
Exterior Rinnai units offer tremendous flexibility and safety. They are mounted on the exterior of your
home so they require no floor space. While they are designed to operate to -30° F, care should be taken to
properly install them in colder climates. |
