How to Fix / Troubleshooting
Emergency safety warning: If you smell gas (rotten egg odor), do not operate any electrical switches, do not use open flames, and evacuate the building immediately. Call your gas supplier and emergency services from outside.
- Do not attempt repairs: Gas leaks and combustion gas intrusion must be handled by licensed professionals with proper leak detection equipment.
- Shut off gas if safe: If you can safely access the main gas shutoff valve without crossing the odor area, turn it off by rotating the handle perpendicular to the pipe.
- Professional inspection: A technician will perform leak tests on the gas piping, valve, and manifold, and inspect the heat exchanger for cracks.
