I am considering an OAK after reading so many posts in favor of it. My stove is on the first floor, vented through the flue. Is it feasible to take the OAK down through the flooring, run across the basement and out - much like the dryer is vented outside? Who installs OAKs - plumbers, stove installers, hvac guys? Anything else I should look for? As usual, thanks for the help.
