How to Fix / Troubleshooting
Safety first: If you smell gas strongly, do not operate electrical switches or the boiler. Evacuate the area and call the gas utility or fire department from outside.
Steps (for minor suspected leak with utility approval):
- Shut off gas: Close the manual gas shutoff valve to the Peerless boiler.
- Soap test: Apply a soap-and-water solution to gas joints and watch for bubbles indicating leaks.
- Tighten or re-pipe: Tighten leaking joints or reassemble with approved gas-rated pipe dope or tape.
- Professional test: Have a licensed technician perform a full leak test and combustion check before returning the boiler to service.
