#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.
