• Burns more efficiently
• Minimizes amount of wood used
• Reduces emissions
• Extends life of furnace
• Reduces bridging
NOTE: The larger the volume where the wood is burning and not drying, the more efficiently the outdoor furnace will be operating.

Operating the Classic Edge for Maximum Efficiency and Performance

Because of its highly efficient and clean-burning design, the Classic Edge
operates differently than other types of wood-burning devices. Understanding
a few basic principles will help you operate the Classic Edge as it was designed,
maximizing its performance, heat transfer and longevity.
NOTE: For proper operation, the fuel must match the heat load, the furnace must be
maintained to ensure proper air flow, and the water temperature must be kept above
150˚F (66˚C).
1. The combustion air fan pressurizes the airbox located at the front of the
outdoor furnace. Primary air flow, regulated by a solenoid, flows into the
firebox through combustion air outlets located on the front, sides and the
back, near the bottom. Secondary air is regulated by solenoids that allow
air flow through the secondary air charge tube. Combustion starts in the
firebox near the bottom of the wood load.
NOTE: The combustion air outlets must be visible (i.e., ash must be kept below the
combustion air outlets as shown).
