Ao Smith 100093633 Pressure Switch Kit Polaris

Product Description

The AO SMITH 100093633 is a pressure switch kit designed for Polaris water heaters. It monitors combustion air and flue gas pressure to verify proper venting conditions before and during burner operation. When pressure falls outside the acceptable range, the switch interrupts the control circuit to prevent unsafe operation. Licensed plumbers and HVAC technicians performing water heater service and maintenance are the primary installers of this component.

This pressure switch kit is intended for use in Polaris high-efficiency gas water heater systems. The Polaris line is a direct-vent, power-vent design commonly installed in residential and light commercial applications. This kit is referenced by superseded part number IS22085 and serves as its replacement.
