I will be installing a new stove ,in the next few weeks , After talking to my sales rep he believes we have can make it work , here is the issue . I will have to go out the home with one 90 or 2 45% . Then i have to 90% over and follow the concrete wall horizontal 14 feet and then 90 up and then another 14 feet to code height i know i need atleast 2 or 3% pitch up on the horizontal run .. So the ? for you guy and gals is is there going to be a issue with the amount of linear feet . and with the bends can i get proper draft . The stove im looking at is the enerzone 3.4. The sales rep says we can make it work .Just looking to see what you think or experts here know .. Thanks
