*To calculate wood figure 3 face cords to make 1 cord

Compare your TOTAL SIZING VALUE to the SUGGESTED SIZING RANGE for the listed models.
* Full cords of medium to high-quality wood


BE SURE TO CONSULT YOUR DEALER WHEN SIZING.  Previous heating efficiencies and heat loss need to be considered when sizing a furnace, THIS IS ONLY A GUIDELINE.
