4. Check that the chimney clean outs fit properly. The flue damper must be fully blocked open or removed
for installation of the E25; the smoke shelves, shields and baffles may be removed if attached by
mechanical fasteners.
5. Stretch the Ø3” (76mm) flex vent liners to the
length needed to ensure they can be easily
connected to the vent terminals.
6. Install the flex pipe assembly up through the
chimney, ensure that the pipe slides through far
enough to connect onto the vent cap. Refer to
table 8 to confirm the vent cap is approved for
use.
7. Most vent caps can be installed onto chimneys
with flue openings up to 16” (406mm) x 16”
(406mm) when the actual flashing is 16” x 16”
or larger. If the chimney is smaller, the flashing
should be trimmed down and folded over.
8. Apply a bead of stove cement sealant to the Ø3”
(76mm) pipe of the exhaust vent terminal. Slide
the flex liner onto the vent terminal and secure
with three (3) sheet metal screws evenly spaced.
