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 15
and 16. 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 flex-
ible gas line connector and 1/2" shutoff valve
(see Step 6 on Page 29).
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 29.

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).
Never use galvanized or plastic pipe. Refer to
Table 6 for proper sizing of the gas supply 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.
IMPORTANT: It is critical that a licensed
installer perform this step strictly per
NFPA.
We recommend that a qualified, licensed
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 consider-
ations of materials, protection, sizing, loca-
tions, controls, pressure, sediment, and more.
Certainly no one unfamiliar and unqualified
should attempt sizing or installing gas piping.

NOTES:
• All appliances are factory-equipped with a
flexible gas line connector and 1/2" shutoff
valve (see Figure 37 on Page 29).
• See Massachusetts Requirements on Page
6 for additional requirements for installa-
tions in the state of Massachusetts in the
USA.
• The gas supply line should not be connected
to the appliance until Step 6 (Page 29).
• A pipe joint compound rated for gas should
be used on the threaded joints. Ensure
propane-resistant compounds are used in
propane applications. Be very careful that
the pipe compound does not get inside the
pipe.
• Sediment Trap: It is recommended to install
a sediment trap in the supply line as close as
possible to the appliance (see Figure 37 on
Page 29). Appliances using propane should
have a sediment trap at the base of the tank.
• Check with local building official for local
code requirements (such as whether below-
grade penetrations of the gas line allowed,
etc.).
