What to do if Rinnai Water Heater exhaust gas temperature is too high?
If your Rinnai water heater shows a high exhaust gas temperature, ensure the condensate line is not blocked and confirm the inlet water temperature is not too high. It is recommended to schedule a service call.
Why Rinnai Water Heater doesn't respond when water flows?
If nothing happens when water flow is activated on your Rinnai water heater, verify you have at least the minimum flow rate required to fire the unit. Clean the inlet water supply filter. On new installations, make sure the hot and cold water lines are not reversed.
