pipe exiting the fireplace. Secure flex vent piep in place
with a hose clamp (provided).

the collars of the fireplace and termination. If the ter-
mination has an internal bead, be sure to overlap and
secure 1” (25 mm) past the bead.
* Be sure the vent is actually crushed before proceed-
ing. Apply a tug to be sure the vent will not slip off the
collars.
