Flex Vent Pipes

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 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” (25mm) past the bead.
