#7 Installing into an existing chimney using 3" pellet
vent in combination with 6" or 8" single or double wall
stove pipe.
This method allows the installer to use 6" or 8" single and
double wall stove pipe (sealed seam not snap lock) and an
existing masonry or class A chimney to vent the stove.
The stove must use pellet vent and 90 degree elbow to start at
the stove connector and then use the approved pipe adapter
to connect to the size of vent that continues into the chimney
connector. Support of the assembly must follow any pipe and
connector manufacturers recommendations.
Due to combustible fuel, vent pipe to hopper clearances must
meet guidelines stated by NFPA or local codes.
