guideline and do not supersede local codes
in any way. Install venting according to local
codes, these instructions, the current National
Fuel Gas Code (ANSI-Z223.1) in the USA or
the current standards of CAN/CSA-B149.1

See Approved Vent Components on
Page 2.
These fireplaces must be vented directly
to the outside.
The vent system may not service multiple
appliances, and must never be connected to a
flue serving a solid fuel burning appliance. The
vent pipe is tested to be run inside an enclosed
wall (such as a chase). There is no requirement
for inspection openings in the enclosing wall at
any of the joints in the vent pipe.
Preparing the Appliance Vent Collar.
Each of the unit's two vent collars are sealed
with a cover plate and a seal plate and gasket.
The cover, and seal plate and gasket must be
removed from the vent collar being used. Refer
to Figure 15 for top vent usage and Figure 16
for rear, and the following steps to prepare the
appropriate collar for use.
From the vent collar being used, remove the four
screws securing the vent seal plate and gasket.
Remove and discard the seal plate and gasket.
When the top vent collar is being used, from
inside the firebox, loosen the two screws in the
keyhole slots of the cover plate and remove the
remaining two cover plate securing screws.
Remove and discard the cover plate. Reinstall
and securely tighten all four screws.
When the rear vent collar is being used, from
inside the firebox, remove the two screws se-
curing the lintel to the rear wall of the firebox,
then remove the lintel. Remove the four cover
plate securing screws.
Remove and discard the cover plate. Rein-
stall and securely tighten all four cover plate
screws. Re-secure the lintel to the rear wall
of the firebox.
