Lennox 19F19 Heater
The Lennox 19F19 (Model ECB29-12.5CB-8P) is a high-performance 12.5kW electric heat kit designed for seamless field installation within Lennox CBA27UHE and CBX32M series air handlers. Engineered for 208/230V single-phase applications, this unit features helix-wound nichrome heating elements that are exposed directly to the airflow, ensuring immediate heat transfer and maintaining lower element temperatures for extended service life. Each element is integrated with a precision-calibrated limit control featuring an automatic reset, coupled with a supplemental thermal cutoff for secondary overheat protection.
This OEM Lennox heater includes factory-installed 35 Amp and 45 Amp circuit breakers, providing essential overload and short-circuit protection while serving as a local disconnect to satisfy most jurisdictional electrical codes. The assembly is housed in a heavy-gauge galvanized steel control box and utilizes a thermal sequencer relay to bring heating stages online in timed increments, preventing excessive amperage spikes. To ensure a professional installation, technicians must apply the included adhesive-backed foam seals to the circuit breaker cover to prevent condensation in the control compartment.
Key Benefits for Technicians:- Direct Air-Stream Exposure: Nichrome elements provide instantaneous thermal response and high efficiency.
- Integrated Circuit Breakers: Built-in 35A and 45A breakers eliminate the need for secondary field-installed disconnects.
- Sequential Loading: Thermal sequencers manage element activation to protect the electrical service and minimize light flicker.
- Plug-and-Play Integration: Low-voltage control plugs directly into the air handler harness for rapid commissioning.
- Corrosion-Resistant Housing: Construction using galvanized steel ensures durability in high-humidity evaporator environments.
Is the circuit breaker cover included with the 19F19?
Yes, the ECB29-12.5CB-8P includes a circuit breaker cover and adhesive-backed seals. If missing or damaged, it must be replaced to prevent warm, moist air from causing condensation on internal electrical components.
Can this heat kit be used in downflow configurations?
Yes, but when installed in a downflow air handler, the circuit breakers must be rotated 180 degrees to the "UP" position per manufacturer specifications to ensure proper orientation and safety compliance.
What air handlers are compatible with this 12.5kW kit?
This heater is primarily designed for the Lennox CBA27UHE series, but it is also widely used in CBX32M and ACBX32M air handlers. Always verify the minimum blower speed requirements in the air handler's engineering handbook.
