LS25-200A-1​ Separated Combustion Unit Heater, 200,000 Btuh, Aluminized Steel

LS25-200A-1​ 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.
