How to fix check gas connections for leaks: step by step

  1. Use a commercial leak-detection soap solution.

  4. Isolate the furnace from the supply during any test at or above 1/2 psig.
Safety: Gas, electrical and refrigerant work must be done by a licensed technician. Turn off power and gas before servicing, never bypass a safety control, and always follow the manufacturer's manual for your exact model.
