  • Page 31: E What Can I Burn

    What should I burn? This furnace is designed to burn well-seasoned cordwood ONLY(unless you have a coal option with shaker grates). Well seasoned wood is wood that has been properly prepared for combustion. Proper seasoning is generally accepted to be wood that has been harvested, split if necessary, and stored for a reasonable amount of time. The most efficient preparation will result in a wood moisture content of 20 percent to 30 percent.

  • Page 32: G Types Of Wood

    At this point the fuel/air mixture is fuel rich. With proper “secondary air” introduction the fuel/air mixture will approach ideal and result in proper combustion. Your Heatmor furnace is designed to create this situation. Wood too high in moisture content results in lower temperatures and unreliable performance.

  • Page 33: J Efficiency Measurements And Types Of Fires

    Heating Efficiency - Output Based The percentage of the heat produced that was actually absorbed into the water and transferred into the house from the Heatmor Net Efficiency This is the product of the combustion and heating efficiencies. Ninety percent combustion efficiency times 60 percent heating efficiency results in a 54 percent net efficiency.
