I recently bought a country wood stove insert and 35 feet of 316ti liner I have a heatalator fire place. I was told by the dealer that the pipe would go right in . when we got the pipe through the damper area to the fire box we were off about 6 inches. I only have a few inches clearance to work with. could use any advice on how to connect flex to stove I cant seem to find any offset adapters on line.
