Heater emits a strong gas smell around the unit, especially at startup.

Safety first: Immediately turn off gas at the shutoff valve and switch off power to the heater. Do not use open flames or create sparks. If you smell a strong gas odor, evacuate the area and contact your gas supplier or fire department.

• Do not operate: Do not attempt to restart the Nirvana heater until the leak is located and repaired.
• Visual inspection: Once safe and with gas off, inspect the gas piping, unions, and Nirvana gas valve and manifold for obvious damage or loose fittings.
• Professional leak test: A licensed gas technician should perform a leak-down test and use an approved leak detection solution or electronic sniffer to locate leaks.
• Repair/replace: Tighten or replace leaking fittings, replace damaged gas valves or manifolds with OEM Nirvana parts, and verify proper ignition timing.
• Combustion check: After repairs, have a professional perform a full combustion analysis to ensure safe operation.
