5.3 Multiple Points of Use
This water heater is designed to supply hot water to 2-3 points of use simultaneously. The advanced sensors and smart technology ensure consistent water temperatures even with varying demand.
6. Maintenance
Regular maintenance ensures the longevity and efficient operation of your tankless water heater. Always disconnect power and turn off the gas supply before performing any maintenance.
6.1 Annual Inspection
- Inspect the vent pipe for any blockages, corrosion, or damage.
- Check all water and gas connections for leaks.
- Examine the heat exchanger for scale buildup. In areas with hard water, periodic descaling may be necessary. Consult a professional for descaling procedures.
- Clean the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners.
6.2 Freeze Protection
The unit has an automatic freeze protection system. For this system to function, the water heater must remain plugged into a 120V/60Hz power supply, especially when ambient temperatures are below 4.6°C (40.3°F) and above 3°C (37.4°F). If the unit is to be left unused in freezing conditions without power, it must be completely drained to prevent damage.

6.3 Draining the Unit
If the unit will be exposed to freezing temperatures and cannot be powered, or for extended periods of non-use, it must be drained:
- Turn off the gas supply to the unit.
- Disconnect the electrical power.
- Close the cold water inlet valve.
- Open a hot water faucet in your home to relieve pressure.
- Open the drain valve on the water heater (or use the manual freeze relief lever if applicable) to allow all water to drain out.
- Once drained, close the drain valve.
7. Troubleshooting
This section provides solutions to common issues. For problems not listed here or if issues persist, contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water / Unit not turning on | No power, gas supply off, low water pressure, flame failure. | Check power connection, ensure gas valve is open, verify water pressure is within range (3.6-116 PSI), check for error codes on display. |
| Water not hot enough | Temperature setting too low, high flow rate exceeding capacity, cold incoming water temperature. | Increase temperature setting on the LED display. Reduce water flow at the faucet. Consider seasonal adjustments. |
| Fluctuating water temperature | Inconsistent water flow, multiple hot water demands simultaneously. | Ensure stable water flow. Avoid excessive simultaneous hot water use if possible. The unit's smart chip should stabilize within 1°F. |
| Unit making unusual noises (e.g., beeping) | Error condition detected (e.g., overheating, pipe blockage, abnormal operation). | Check the LED display for specific error codes. Refer to the full manual for error code definitions and solutions. If no code, power cycle the unit. If persistent, contact support. |
| Water leaks | Loose connections, damaged pipes, internal component failure. | Immediately turn off water and gas supply. Inspect all connections. If leak persists or is internal, contact a qualified professional. |
Important: If you encounter an error code or a problem you cannot resolve, do not attempt to repair the unit yourself. Contact LiberLive customer support or a qualified technician.
