Verify Gas Supply
Check the gas supply if you have a gas-powered Navien water heater. Make sure the gas valve is open and unobstructed. Inspect the gas line for leaks or damage. If you smell gas, evacuate the area and contact a professional immediately. If the gas supply is intact, check for proper pressure using a manometer or contact your gas supplier for assistance.
