with the current CSA-B149.1 installation code.

The venting system must conform to local codes and/or
the current National Fuel Code ANSI Z223.1/NFPA 54.
Only venting components manufactured by CFM Cor-
poration may be used in Direct Vent systems.
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).
*Be sure the flex pipe overlaps at least 1" (25mm) onto
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.
