Venting - Hearth Mount - St. Croix SCR Installation & Operation Manual

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
a cold chimney environment.
