Lennox 99M66 Heater Kit
The Lennox 99M66 (Model: ECB26-7CB-PP) is a field-installable 7.5kW electric heater kit designed for high-performance integration with CBX26UH series air handlers. Operating on a 208/240V single-phase 60Hz power supply, this kit provides a nominal heat output of 25,600 BTUH at 240V, making it an essential component for supplemental or primary heating in residential and light commercial forced-air systems. The assembly features an integrated circuit breaker, which serves as a necessary disconnect and provides robust overload and short-circuit protection directly at the unit. Helix-wound nichrome elements are exposed directly in the airflow for instantaneous heat transfer and consistent discharge temperatures. This OEM Lennox part includes a thermal sequencer relay for staged element activation and is factory-wired with a mating plug-in connector to simplify control circuit interfacing with the air handler’s main control box.
Key Benefits- Integrated Circuit Breaker: Provides localized safety disconnect and overcurrent protection, often eliminating the need for an external field-supplied disconnect.
- Fast Heat Transfer: Open nichrome heating elements ensure immediate response times and high thermal efficiency in the air stream.
- Safety Controls: Equipped with primary and secondary high-temperature limit controls featuring automatic reset functionality.
- Simplified Installation: Factory-assembled with a dedicated wiring harness for quick connection to compatible Lennox air handlers.
- Reliable Sequencing: Utilizes a thermal sequencer to delay blower start/stop and stage elements, preventing sudden voltage drops in the electrical system.
Is the Lennox 99M66 compatible with all air handlers?
No, this kit is specifically engineered for the Lennox CBX26UH series. Always verify the cabinet size and airflow requirements before installation.
Does this heater kit require a separate power supply?
This single-phase electric heat kit typically shares the main power source with the air handler. Consult the Minimum Circuit Ampacity (MCA) and Maximum Overcurrent Protection (MOP) ratings on the unit nameplate for proper wire sizing.
Can this be used in downflow applications?
Yes, the 99M66 heater kit is rated for multiple orientations, though downflow installations on combustible flooring may require an additional base kit per safety codes.
