559CLT Co-Linear Terminal and 559SFK Square Flashing Kit are
recommended—see list of approved venting accessories on page 22.
Cut flashing kit to size. Allow extra around perimeter for drip edge to
be formed on site. Seal flashing to top of chimney using sealant (not
supplied). Fasten terminal to flashing using sheet metal screws as
shown.
Existing Round Factory-Built Chimneys
The 559CLT terminal is designed to fit existing 7" or 8" diameter factory-built round chimneys without requiring
additional flashing. Ensure the installation of the terminal seals off the top of the chimney space to avoid convective
air loss. The diagrams below show a typical terminal installation for an 8" diameter air-cooled chimney system.

Vent Termination

The RF24 is approved for Vertical Co-Linear Termination Only. Two 3" diameter liners
are required from top to bottom. The vent liners must be connected to the proper collars
(intake and exhaust) or the unit will not operate properly. The method of flashing will
depend on whether the liners are installed into a rectangular masonry or round factory-built
solid-fuel burning chimney. It is important to seal the gap at the top of the chimney in
either case to avoid convective air loss up the chimney. The integrity of the air-cooled
function of factory-built chimney systems must be maintained when installing terminations.
Termination of the chimney may need to be completed after the RF24 firebox is
installed and the slack vent liner pulled up—see Section Firebox Installation.
