The result is exquisite and reliable heating for decades to come. With the standard bypass damper we’ve given you full control over the flow of smoke inside your Evergreen. Simply open the bypass via the pull ring located just above the door to draw smoke away from the door and up the chimney. Close the damper to drive smoke around the baffle and initiate the efficient secondary combustion process. Your burn rate, from a mellow overnight burn to a large rolling fire, is effortlessly managed by a single air control knob found below the stove’s door.
