Lennox 19F12 Heater Kit
The Lennox 19F12 is an OEM 5kW Heater Kit with Circuit Breaker designed for field installation within compatible air handler units. This 208/240V single-phase electric heat section, officially designated as model ECB29-5CB-7P, provides 17,100 BTUs of supplemental heat at 240V. Engineered for the CBA27UHE series air handlers, it utilizes helix-wound nichrome elements that are exposed directly to the airstream for immediate heat transfer and optimized thermal performance. The integrated 35 Amp circuit breaker functions as a primary safety mechanism, offering overload and short-circuit protection while potentially serving as a local disconnect depending on regional electrical codes.
For technicians performing a retrofit or replacement, the Lennox 19F12 features factory-wired connections and a current-sensitive, temperature-actuated manual reset limit control. This ensures high-limit protection and consistent operational safety. The unit is ETL listed and includes all necessary mounting hardware for a secure fit within the air handler deck. Its compact 4.7 lb frame and official Lennox HVAC OEM part status guarantee physical and electrical compatibility, reducing field modification time during critical heating season service calls.
Key Benefits- Provides a robust 5.0 kW heating capacity (17,100 BTU @ 240V) for effective supplemental or primary heating.
- Includes a built-in 35A circuit breaker specifically sized for overload protection and system safety.
- Features high-grade nichrome heating elements for rapid heat-up and long-term durability in the airstream.
- Developed as an official Lennox OEM part to ensure seamless integration with CBA27UHE air handlers.
- Equipped with accurately located fixed-temperature limit controls for positive thermal protection.
What air handlers are compatible with the Lennox 19F12?
This kit is engineered primarily for the CBA27UHE series, though it may fit other ECB29 series compatible units such as the CBX27UH or CBX32M depending on the cabinet size and specific wiring harness. Always verify the air handler's data plate before installation.
Does this heater kit require a separate disconnect?
In many jurisdictions, the integrated 35 Amp circuit breaker qualifies as a unit disconnect. However, you must consult your local electrical code to determine if a secondary field-provided disconnect is required for your specific installation.
What size wire is required for a 5kW heater kit?
For this 208/240V 1-phase application, you generally require wires suitable for at least 167°F (75°C). Always refer to the National Electrical Code (NEC) or Canadian Electrical Code (CEC) to determine the exact wire gauge and fuse requirements based on the Minimum Circuit Ampacity (MCA) listed on the unit.
