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 4.
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 24
, 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 24
)
. Place the
restrictor inside the appliance 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 termination 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 40 and 41.
