We have a Comfort Glow B42LI-M wood burning box. First flue liner needs to be offset elbow. Should inner liner go inside outlet on box or should it be outside?

Our Answer:

The general rule of thumb is for vent pipe to be installed male end down. So, the liner would go inside the flue outlet. Of course, most factory boxes require specific brands of pipe that feature locking tabs and ensure a proper fit/connection.
