TERMINATION
NOTE: Masonry fireplace installations require a direct connection or positive (complete reline) connection to the chimney
flue. With a direct connection a block-off plate made of metal or other non-combustible material (i.e. Kaowool or
high temperature fiberglass insulation) must be used at the damper location and sealed airtight. The singlewall
pipe or flexible liner must extend past the block-off plate or insulation by one (1) foot (305 mm) or to the first flue
tile if the chimney has a tile lining.
With a positive connection, the block-off plate at the damper location is optional, but a sealed cover plate is
required at the top of the chimney. A positive connection (complete reline) is recommended for ease of cleaning.
