Allied Commercial Lennox LF24-100A Steady State Efficiency Unit Heater 100,000 BTU

Lennox 100,000 BTU 80.5% Steady State Efficiency Gas-Fired Unit Heater LF24-100

One standard feature of all Lennox unit heaters and duct furnaces is the tubular heat exchanger, designed to enhance performance and reliability. The exchanger’s curved design provides excellent heat transfer by completely exposing the heating surface to the air stream. Rounded surfaces minimize air resistance and even heating is allowed across all surfaces, reducing stress on theheat exchanger.

The many other advanced features include an in-shot burner assembly that’s simple to clean and easily within reach, plus safety valves and switches and efficient direct-spark ignition. A self-diagnostic board with LED readout simplifies troubleshooting.

Each unit is shipped completely assembled with factory-wired controls and tested with complete cycles of start-up and shutdown, as well as acceptable gas and electrical operation verification for quick and easy unit start-up on the jobsite. The low cabinet profile of the LF24 and TU models allows installation even in tight spaces and helps where appearance is a concern. The simple-to-install units feature either mounting brackets or spotnuts and centrally located connections for gas, line voltage and thermostats.

Several heating capacities are available, making it easy to keep both small and larger spaces comfortable. These reliable heaters and furnaces are available with your choice of natural gas or propane, and several wall venting options—including horizontal and vertical—allow the units to be placed in a number of locations.
