York S1-4HK165N1506 Heat Kit

The York S1-4HK165N1506 is a field-installed 15kW electric heat kit designed specifically for compatibility with York, Luxaire, and Coleman air handlers and modular blowers. This 208/240V single-phase heater assembly provides reliable supplemental or primary heating, featuring nickel-chromium heating elements for consistent thermal transfer and corrosion resistance. The unit incorporates sequenced staging to prevent high-amperage surges during startup, maintaining electrical stability within the system. Equipped with built-in circuit breakers, this kit simplifies installation by providing integrated overcurrent protection directly at the unit, streamlining the wiring process for contractors. The thermal limit switches serve as a critical safety interface, preventing overheating by interrupting power if airflow is restricted. For technicians performing retrofits or new installs, this heat kit ensures precise fitment and OEM-level performance in residential and light commercial split system applications.

• High-grade nickel-chromium elements ensure long-term durability and resistance to oxidation in high-cycle environments.
• Integrated 60-amp circuit breakers eliminate the need for external disconnects in many applications, reducing labor time.
• Plug-and-play wiring harness allows for seamless integration with the air handler's control board.
• Automatic reset thermal limits provide reliable protection against high-temperature excursions.
• Staged heating cycles improve comfort and reduce the electrical load on the building's infrastructure.

Common Questions

Is the S1-4HK165N1506 compatible with multi-position air handlers?
Yes, this heat kit is designed for use in upflow, downflow, and horizontal configurations, provided the air handler matches the S1-4HK series technical specifications.

What gauge wire is required for a 15kW heat kit installation?
Installation usually requires 6 AWG copper wire for the auxiliary heat circuit, though you must verify local electrical codes and the unit’s nameplate MCA (Minimum Circuit Ampacity) before finalizing the run.

Does this kit include the necessary limit controls?
Yes, the assembly includes factory-installed primary and secondary thermal limits to ensure safe operation within the blower cabinet.
