I wired the blowers direct to test they run good nice and quiet. I try to get standing dead wood then have it split and covered 9 months plus so wood should be good this years batch was perfect. I will have to check but but I thinks its a single speed blower. I will definitely have to check draft chimney will be around 35' of 6" liner then about 6' stove pipe in the basement with a 90 on the back and most like a T on the bottom of the liner with a 45 connecting them. A key damper may be necessary.
