LENNOX WINTER AIR CONDITIONING UNITS
The Lennox line of warm-air heating and air-conditioning equipment is complete, containing units specially designed for
every type of fuel, and sizes ranging from 50,000 to 1,000,000 Btu per hour at the register. All heaters are of the famous riveted, calked steel construction--per manently gas- and dust-tight. Every unit throughout the line is designed to deliver air at uniform temperature and velocity to all warm-air ducts. As a result, these
units are unusually easy to balance. Lennox units have long been famous for
their high efficiency, quick response to temperature changes and long life. The company has been manufacturing steel warm-air heating equipment for more than 40 years and have pioneered the field of residential forced-air heating. Complete specifications and descriptions of the com plete line on request.
