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 venting according to local codes,
these instructions, the current National Fuel
Gas Code (ANSI-Z223.1) in the USA.
These fireplaces are designed, tested and
listed for operation and installation with,
and only with, Secure Vent™ (SV4.5) Direct-
Vent System Components, manufactured by
Security Chimneys International. These ap-
proved vent system components are labeled
for identification. DO NOT use any other
manufacturer's vent components with these
appliances.
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
ue 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.
Venting System
With the appliance secured in framing, de-
termine vent routing and identify the exterior
termination location. The following sections
describe horizontal (exterior wall) vent applica-
tions. A list of approved venting components
is shown on Page 28.
