Canadian Installations:
The venting system must be installed in accordance with
the current CSA-B149 .1 installation code.

The venting system must conform with local codes and/or the
current National Fuel Gas code ANSI Z223.1/NFPA 54.

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 pipe in place with a hose
clamp (provided).
*Be sure the flex pipe overlaps at least 1" (25 mm) onto the
collars of the fireplace and termination. If the termination
has an internal bead, be sure to overlap and secure 1" (25
mm) past the bead.
