Before joining the flex vent pipe to the unit, apply a bead
of high temperature sealant* (provided) to the 4” pipe
exiting the fireplace. Secure flex vent pipe in place with
a hose clamp (provided).
*Be sure the flex pipe overlaps at least 1” (5 mm) onto
the collars of the fireplace and termination. If the termi-
nation has an internal bead, be sure to overlap and se-
cure 1” (5 mm) past the bead.

* Be sure the vent is actually crushed before proceeding.
Apply a tug to be sure the vent will not slip off the collars.
Repeat process with 7” flex vent pipe. The same proce-
dure must be performed on the vent side.
