Step 3. INSTALL THE VENT SYSTEM
General Information
These instructions should be used as a guide-
line and do not supersede local codes in any
way. Install vent according to local codes,
these instructions, the current National Fuel
Gas Code (ANSI-Z223.1) in the USA or the
current standards of CAN/CGA-B149.1 and
-B149.2 in Canada.
Use only approved venting components. See
Approved Vent Components on Page 2.
These fi replaces must be vented directly
to the outside.
The vent system may not service multiple
appliances, and must never be connected to a
fl ue serving a solid fuel burning appliance. The
vent pipe is tested to be run inside an enclosing
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 cap. The cover
plate and seal cap must be removed from the
cent 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
screw securing the vent seal cap. Twist the cap
counterclockwise to disengage it from the vent
collar. Remove and discard the seal cap.
When the top vent is being used, remove the
lintel cover plate by pushing it back towards
the rear of the fi replace by its front fl ange. It
can then be removed by pulling it forward.
Loosen the two screws in the keyhole slots of
the vent cover plate and remove the remaining
two vent cover plate securing screws. Remove
and discard the vent cover plate. Reinstall and
securely tighten all four cover plate screws.
Reinstall the lintel cover plate.
When the rear vent is being used, from inside
the fi rebox, remove the two screws securing the
baffl e to the rear wall of the fi rebox, then remove
the baffl e. Loosen the two screws in the keyhole
slots of the cover plate and remove the remaining

discard the cover plate. Reinstall and securely
tighten all four cover plate screws. Re-secure
the baffl e to the rear wall of the fi rebox.
