To determine the diameter of pipe to use (3"or 4"), you can use the following guidelines.
Fillout the installation chart (table 1), and calculate your total equivalent pipe length.
Then use the total equivalent pipe length and the altitude in the pipe selection chart. (pic.11) to determine if your installation requires 3" or 4" exhaust pipe.

Equivalent pipe lenght = (10 + 3 + 1 + 1) ft = 15 ft
If the stove is installed in a place with an altitude of 2000 ft,
it is possible to use either a pipe of 3" or of 4", as you can
see in the pipe selection chart below.
