Make sure that in case of freezing weather that the water heater and its water lines are protected to prevent freezing. Damage due to freezing is not covered by the warranty.With electrical power and gas supplied, the water heater will not freeze when the outside air temperature is as cold as –22°F (-30°C) for indoor models or is as cold as –4°F (-20°C) for outdoor models, when protected from direct wind exposure. Because of the “wind-chill” effect, any wind or circulation of the air on the unit will reduce its ability to protect itself from freezing.In the event of a power failure and/or gas interruption at temperatures below freezing the water heater should be drained of all water to prevent freezing damage. In addition, drain the condensate trap and drain line.Loss of freeze protection may result in water damage from a burst heat exchanger or water lines. The unit may be drained manually. However, it is highly recommended to:drain down solenoid valves be purchased and installed that will automatically drain the unit if power is lost. These are available in a kit, 104000059. (The condensate trap is not affected by the auto drain down solenoid valves and will have to be manually drained.)a surge protector with terminals be purchased and installed which allows the solenoid valves to operate if the unit is disabled due to a diagnostic code. This is available as 104000057.In addition, the solenoid valves should be connected electrically to a surge protector with terminals. This allows the solenoid valves to operate if the water heater is disabled due to a diagnostic code. The freeze protection features will not prevent the external piping from freezing. It is recommended that hot and cold water pipes be insulated. Pipe cover enclosures may be packed with insulation for added freeze protection. --Tashay

3rd purchase, Works well with some caveats
My 1st unit lasted 9 years. I followed the instructions of the manual and flushed out with vinegar every 6 months. The vinegar ate thru a copper line and the unit sprayed water ruining the electronics. 2nd unit worked fine for 2 years untill we had 5 days below freezing with 18 hrs below 14 degrees. Reading the manual the unit is rated to -30 - "A Rinnai tankless water heater features built-in freeze protection, so it will remain in operation in temperatures as low as -30℉" but the caveat of power was not a consideration in my mind but Texas ERCOT decided I didn't need power for 120 hours! Had I known I would have read the very print on page 42 of the manual of the steps you need to take before it freezes and you still power. 3rd unit works well in the sunshine!
