Vent Connection
The Vent Collar Plate, located on top of the cabinet,
is removable to ease connection of the vent liners in
those cases where access within the fireplace is
restricted. Whether you are venting through a
masonry chimney or a prefabricated chimney, the
flex liner is connected to the insert in the same way.
Use the following procedure.
