Questions and answers
Unit working on LO & Med but will only work for a couple minutes on high. Then shuts it self down.
The Rinnai REH-20DT could be shutting down after a few minutes of running on high due to several possible reasons:
1. Oxygen Depletion Sensor (ODS) Activation – If the heater is in a poorly ventilated area, the ODS may detect low oxygen levels and shut the unit off for safety.
2. Gas Supply Issue – If the gas pressure is insufficient or does not match the rating plate requirements (LP or NG), the heater may not function properly.
3. Blocked or Dirty Components – A clogged burner or pilot assembly can cause improper combustion, leading to shutdown.
4. Overheating Protection – If the heater is located too close to combustible materials or restricted airflow, it may overheat and shut down as a safety measure.
5. Faulty Thermostat or Controls – If the thermostat control (on T-Models) malfunctions, it might cause the heater to cycle off incorrectly.
Checking ventilation, gas supply, and cleaning the heater may help resolve the issue. If the problem persists, professional inspection is recommended.
