Questions about this item

Does the HC21ZS123 inducer motor come with a mounting bracket, gasket, or wiring harness, or are those purchased separately?

The listing specifies "INDUCER MOTOR ONLY," meaning the motor itself is the sole component included. Mounting hardware, gaskets, and electrical connectors are not supplied and must be sourced separately to complete the installation.

How do I confirm the HC21ZS123 is the correct replacement for my specific furnace or boiler model?

Match the part number HC21ZS123 exactly to the number printed on your original inducer motor or listed in your appliance service manual. Verifying this number ensures the voltage, rotation, and mounting alignment match your equipment.

What does the "INDUCER MOTOR ONLY" designation mean for installation once the part is in the appliance?

It indicates the assembly arrives as the bare motor unit without the fan wheel, housing, or mounting plate attached. You must transfer the existing fan wheel and reuse the original mounting hardware to reinstall it into the appliance.
