Figure 8. Venting to the Top of Chimney
When installing as a hearth mount stove into a fireplace the unit must either be relined,
terminating above the chimney chase top, or positively connected to the existing chimney system
using a block off plate (D). An approved flex liner of PL vent must be used.
A chimney system
with known drafting problems may require a liner, which may also need to be insulated to
keep vent system warm in cold chimney environment.
