Want to connect a 8 flue to a 6 chimney will this work with my new wood burning stove?

It will not work very well. Many days when you open the door the smoke will come out the door. You can purchase a reducer to make it work, but if there is any possible way to install the 8 inch pipe, I would recommend it.

I sell stoves in BC. Codes here dictate that you can only step down the flue size by 1 inch. Make sure you check with your insurance company. They will look for anything to void your coverage if there is a fire. I agree with the fellow above: put in an 8" chimney or get a stove with a 6" collar.
