    Last night my stove started backpuffing at 450*. What should I do to get more draft?
    1. Add 5' of Class A 8" chimney pipe to have 20' of chimney.
    2. Put in a 6" liner that will be 15'
    3. Add 5' of Class A 8" Chimney and put in a 6" liner of chimney to have 20' of chimney.
    4. start over and run a 6" Class A chimney at 15'

    Your stove has an 8" exhaust, I would not recommend switching to 6" on that small of a run. I would put in double wall 8" from the thimble to your stove and if that doesn't help then add a few feet of class A and brace it.

    Agreed, 5ft may not be needed I'd add a 3 ft section of class A and brace the pipe at 5ft above the roof.
