Lennox 19F27 Heat Kit
The Lennox 19F27 is a high-performance 10kW 240V 3PH Heat Kit engineered for seamless integration into compatible Lennox air handlers and packaged units. As a veteran-grade electric heat section, this OEM component provides critical supplemental heating capacity for three-phase commercial and residential applications. Operating at 10 kilowatts on a 208-240V 3-phase circuit, it ensures a balanced electrical load and reliable thermal output during peak demand. The ECB29-10-3P series features high-grade helix-wound nichrome elements positioned directly in the airflow for instantaneous heat transfer and long-term durability. Designed for field installation, the assembly includes a built-in terminal block to simplify high-voltage wiring and integration with existing HVAC controls. Safety is maintained through primary limit controls and thermal cutoffs, providing positive protection against excessive temperatures without the need for additional field-provided disconnects in many jurisdictions.
Key Benefits- Optimized Thermal Transfer: Exposed nichrome elements provide immediate response times and efficient supplemental heating.
- Three-Phase Stability: Specifically designed for 240V 3-phase HVAC systems to balance power distribution and reduce operational strain.
- Simplified Field Installation: Integrated terminal block and pre-cut mounting holes facilitate rapid deployment for contractors.
- Rugged Safety Features: Equipped with automatic reset limits and supplemental thermal cutoffs to protect the air handler cabinet.
Is the Lennox 19F27 compatible with single-phase systems?
No, this specific model is a 3-phase heat kit. Attempting to install this on a single-phase power supply will result in equipment failure and electrical hazards. Always verify the phase and voltage of your service before installation.
Does this kit include a circuit breaker?
The 19F27 is a terminal block model. While some ECB29 series units include circuit breakers (noted as "CB" models), this version utilizes a terminal block for direct wiring into the system's power distribution.
What is the minimum blower speed required for this 10kW kit?
For most Lennox air handler applications using the 10kW heat section, the blower speed must be set to High to ensure proper static pressure and heat dissipation across the elements.
