The red arrow at the right is pointing to proof positive that the Lynndale Furnace is built to last for years. The unit shown was installed in this building in the late-1970’s, and it is still used to heat it each winter, after all of these years.

The firebox of a new Model 1025 is also shown here, before the insulated cabinet is added.
Note the reinforcement that is added to the upper firebox area of the industrial models, to assure a long life of each and every Lynndale System.
