Step 3. Appliance Vent Collar; Step 4. Install The Venting System - Lennox EDV3530CNM-B Installation Instructions Manual

Step 3. 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 16 for
top vent usage and Figure 17 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 fireplace by its front flange. 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.

Step 4. INSTALL THE VENT SYSTEM
General Information
These instructions should be used as a
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
in Canada.
Ensure clearances are in accordance with
local installation codes and the requirements
of the gas supplier.
Dégagement conforme aux codes d'installation
locaux et aux exigences du foumisseunde gaz.
Use only approved venting components.
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.
Installation of Vent Restrictor
A vent restrictor may be needed with this
appliance. The restrictor is installed in the
appliance top flue outlet as shown in Figure
16, either before adding vent, from above, or
after installation of vent from below, within the
firebox. The restrictor is self securing through
a positive friction fit.
Determine the venting for the appliance. If the
vent run will include at least 8 feet of vertical
rise, then install the restrictor in the appliance
collar before connecting any vent (Refer to
Figure 19 ). Place the restrictor inside the ap-
pliance vent collar and press in place.
Note: The restrictor is included within the
firebox.
Select Venting System - Horizontal or Vertical
With the appliance secured in framing, determine
vent routing and identify the exterior termina-
tion location. The following sections describe
vertical (roof) and horizontal (exterior wall)
vent applications. Refer to the section relating
to your installation. A list of approved venting
components are shown on Pages 34 and 35.
