Initial Startup:
- Ensure all water and gas connections are secure and leak-free.
- Open the cold water supply valve to the RV.
- Purge air from the hot water lines by opening a hot water faucet inside the RV until water flows steadily.
- Turn on the propane gas supply.
- Power on the water heater using the remote controller.
Temperature Adjustment:
Use the intelligent remote controller to set your desired hot water temperature. The temperature range is from 95°F (35°C) to 124°F (51°C).

- Ventilation: Ensure the exhaust and intake vents are clear of obstructions.
Troubleshooting
This section provides solutions to common issues. For problems not listed here, contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water / Unit not igniting | No gas supply, low water flow, power issue, error code (e.g., E5) | Check propane tank, ensure water pressure is adequate, verify power connection, consult remote controller for error codes and refer to specific error code section (if available in full manual). |
| Water not hot enough | Temperature setting too low, excessive water flow, cold inlet water temperature | Increase temperature setting on remote, reduce water flow at faucet, allow unit more time to heat. |
| Unit cycles on/off frequently | Low water flow, air in lines, restricted exhaust/intake | Ensure adequate water flow, purge air from lines, check for obstructions in vents. |
| Error Code E5 | Commonly indicates a flame failure or ignition issue. | Check gas supply, ensure proper ventilation, reset the unit by turning off and on. If persistent, contact customer support. |
