the stove door, 8” (20.3cm) beyond the sides of the door, and under the pipe and 2” (5cm)
beyond for back venting.
When installing the stove, the heat distribution to other rooms should be taken into
consideration. The approximate heating area (based on standard ceiling height) and
thermal output are:
