Proper Sizing of Gas Line
Properly size and route the gas supply line
from the supply regulator to the area where the
appliance is to be installed per requirements
outlined in the National Fuel Gas Code, NFPA
54 - latest edition (USA) or CAN/CGA-B149.1
- latest edition (Canada).
IMPORTANT: It is critical that a licensed
installer perform this step strictly per
NFPA.
Never use galvanized or plastic pipe. Refer
to
Table 6
for proper sizing of the gas sup-
ply line, if black iron pipe is being used. Gas
lines must be routed, constructed and made
of materials that are in strict accordance with
local codes and regulations. We recommend
that a qualified individual such as a plumber or
gas fitter be hired to correctly size and route
the gas supply line to the appliance. Installing
a gas supply line from the fuel supply to the
appliance involves numerous considerations of
materials, protection, sizing, locations, controls,
pressure, sediment, and more. Certainly no one
unfamiliar and unqualified should attempt sizing
or installing gas piping.
NOTE:
• All appliances are factory-equipped with
a flexible gas line connector and 1/2 inch
shutoff valve (see
Figure 37
on
Page 26
)
.
• See
Massachusetts Requirements
on
Page
7
for additional requirements for installations
in the state of Massachusetts in the USA.
• The gas supply line should not be connected
to the appliance until
Step 6
(
Page 26
)
.
• A pipe joint compound rated for gas should
be used on the threaded joints.
Be very careful
that the pipe compound does not get inside
the pipe.
• It is recommended to install a sediment trap
in the supply line as close as possible to the
appliance (see
Figure 37
on
Page 26
)
.
• Check with local building official for local
code requirements (i.e. are below grade
penetrations of the gas line allowed?, etc).

Step 2. ROUTE GAS LINE
NOTICE: For indoor/outdoor installations,
the CONTROL SIDE of the fireplace must
be installed on the INDOOR side.
Route a 1/2" (13 mm) gas line along the inside
of the right side framing as shown in
Figures 13
and 14
. Gas lines must be routed, constructed
and made of materials that are in strict accor-
dance with local codes and regulations.
All appliances are factory-equipped with a
flexible gas line connector and 1/2 inch shutoff
valve
(see Step 6 on Page 26).
The incoming gas line should be piped into
the valve compartment and connected in one
of the two methods as shown in
Figure 37
on
Page 26
.
Step 3. INSTALL 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 or the
current standards of CAN/CGA-B149.1 and
-B149.2 in Canada.
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’installa-
tion locaux et aux exigences du foumis-
seunde 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.
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
