LS25 Commercial Separated Combustion Unit Heater
Increased Application Flexibility
The LS25 Separated Combustion Unit Heaters utilize high-temperature silicone gaskets to provide a superior seal and leakage rates that are up to 57% lower* than those allowed under ANSI Z83.8. Lennox goes above and beyond to deliver a tight, durable seal because that is the key to unmatched durability and efficiency over the life of a separated combustion product in harsh environments. The LS25 design simplifies installation of the unit by not disturbing any of the factory-installed seals or requiring messy, field-applied sealants.
