• Check Exhaust Port: Ensure the exhaust port remains clear of obstructions (e.g., debris, insects, nests).
• Battery Replacement: Replace the ignition batteries annually or when the ignition becomes unreliable.

Winterization (for outdoor use in freezing climates):

To prevent damage from freezing, especially if the unit is used outdoors or in unheated areas:

1. Turn off the gas supply to the water heater.
2. Turn off the water supply to the water heater.
3. Disconnect the water inlet and outlet hoses.
4. Allow all water to drain completely from the unit. Tilting the unit slightly may help.
5. Store the unit in a dry, frost-free location if possible, or ensure it is completely drained if left in place.

7. Troubleshooting

If you encounter issues with your water heater, refer to the following common troubleshooting steps. For complex problems, contact a qualified technician.

Common Issues and Solutions:

• No Hot Water / Unit Not Igniting:
  • Check if the gas supply is open and there is sufficient gas pressure.
  • Ensure the water supply is open and there is adequate water flow.
  • Verify that the batteries for ignition are correctly installed and not depleted. Replace if necessary.
  • Check if the water flow rate is too low. Increase water flow using the water control knob or by opening the faucet further.
  • Ensure the exhaust port is not blocked.
• Water Not Hot Enough:
  • Adjust the Gas control knob towards 'Max'.
