- Open Water Supply: Turn on the cold water supply to the unit. Ensure water pressure is within 3-145 PSI.
- Adjust Controls:
- Set the Season Control Center to "Winter" for higher temperatures or "Summer" for lower temperatures.
- Adjust the Gas Control Center (Min/Max) to regulate the flame intensity.
- Adjust the Water Control Center (Low/High) to regulate water flow. Lower flow generally results in hotter water.
- Initiate Hot Water: Open the hot water faucet or shower head. The unit will automatically ignite, and the digital display will show the water temperature.
