A Heartland Wood Cook Stove Fresh Air Kit enables you to use outside air, instead of room air to fuel the fire. Using an outside source for combustion air has its advantages. If your home is tight and well insulated, then the fire in the stove may be “starved” of combustible air, it will be difficult maintaining a fire, and you may have back drafting problems. During the heating season, cold air, (which is more dense than warm air), will cause the fire to burn a little hotter, resulting in more BTU’s from your wood, and less creosote build-up.
