- Freeze Protection: For installations in environments below 18°F, an automatic drainage accessory is recommended to provide freeze protection by draining water during power outages.
5. Troubleshooting
This section provides basic troubleshooting steps for common issues. For more complex problems or if issues persist, contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water / Unit not igniting | No gas supply, low water flow, power issue, flame sensor error. | Check gas valve, ensure adequate water flow (min 0.5 GPM), verify power connection, consult manual for error codes. |
| Inconsistent water temperature | Fluctuating water pressure, mineral buildup in heat exchanger, incorrect temperature setting. | Check water pressure, consider annual flushing, adjust temperature setting on remote control. |
| Low hot water flow | Clogged inlet filter, restricted plumbing, multiple fixtures running simultaneously. | Clean inlet filter, check plumbing for kinks/restrictions, reduce simultaneous hot water usage. |
| Unit displays error code | Internal fault or specific operational issue. | Refer to the detailed User's Manual for specific error code meanings and solutions. If unresolved, contact customer support. |
