How can I verify the gas supply to my Rinnai water heater?


James Thompson, Water Heater Repair Expert

To check the gas supply to your Rinnai water heater, first, ensure the gas valve is in the ‘ON’ position. Next, check the gas pressure using a manometer. If the pressure is too low, it may not be sufficient to heat the water. If you’re unsure about any of these steps, it’s best to consult with a professional.
