PRODUCT INFORMATION, INSTALLATION AND MAINTENANCE
When chimneys are relined, a chimney chase cap that reduces the
outlet of the chimney to the size of the liner is required. Extend
the exhaust vent above the chimney chase cap and finish it off
with a rain cap.
A single wall liner may need to be insulated to maintain ade-
quate exhaust temperatures in the vent system.
a
Outside Chimneys frequently are difficult to keep
warm: it is recommended that you insulate the liner.
Venting into the side of an existing masonry chimney must be
done through a masonry thimble. When wall penetration is nec-
essary to access a masonry chimney, use a listed PL vent wall
thimble.
When venting into a Class A steel chimney, use an appropriate PL
Vent adapter.

An approved flex liner of PL vent must be used.
