Weil McLain 381-359-295 Inducer Kit

The Weil McLain 381-359-295 is the inducer kit for CGi Series 4 boilers in sizes 4 through 6. The inducer is the draft motor and fan that pulls combustion air through the burner and heat exchanger and drives the flue gases out the vent. When it wears out the symptoms are the ones a boiler tech knows well: bearing noise, a boiler that will not prove draft, and lockouts because the pressure switch is not seeing airflow.

381-359-295 supersedes 381-359-293. Weil-McLain's CGi Series 4 parts book lists the 381-359-293 kit as an inducer fan assembly kit that includes the inducer fan assembly, gasket and nuts, for CGi sizes 4 through 6. If your records, parts book, or old invoice call for 381-359-293, order 381-359-295. The inducer kits are size-specific across the line: 381-354-588 is the kit for CGi sizes 25 and 3 and 381-359-294 is the kit for CGi sizes 7 and 8, so the number has to match the boiler. The inducer mounting gasket is also available on its own as 590-317-627.

On the job, shut off the gas and power, and disconnect the inducer wiring only after labeling the leads. Inspect the vent connection, condensate path, and pressure switch tubing while the inducer is out — a blocked vent or a cracked tube can mimic a failed inducer. After the new kit is installed, confirm a clean draft proof, check combustion, and verify the vent system for leaks before the boiler goes back in service.
