ASSEMBLING VENT PIPE
Only venting components manufactured or approved by
Vermont Castings Group may be used in Direct Vent sys-
tems.
USA Installations
The venting system must conform to local codes and/or
the current National Fuel Code ANSI Z223.1/NFPA 54.
Canadian Installations
The venting system must be installed in accordance with
the current CSA-B149.1 installation code.
FLEX VENT PIPE
Secure fl ex vent pipe in place with a hose clamp (provid-
ed).
•
Be sure the fl ex pipe overlaps at least 1" (25 mm) onto
the collars of the fi replace and termination. If the ter-
mination has an internal bead, be sure to overlap and
secure 1" (25 mm) past the bead.
•
Tighten fl ex clamp to fl ex pipe so it is tight to collar and
cannot slip off.
•
Apply a tug to be sure the vent will not slip off the col-
lars.
•
Repeat process with 7" fl ex vent pipe. The same pro-
cedure must be performed on the vent side.
