Route the Gas Supply Line into the Fireplace
NOTE:
See
Page 53
for more information on
Accessing the Control Compartment
.
NOTE:
If gas shutoff valve on the fireplace is desired, surround kit must be used. Refer the gas line routing included in
the surround instructions.
1.
Route a 1/2” (13 mm) gas line to the left side of the fireplace (
Figure 9
).
2.
Route the gas line through the gas supply line access opening (
Figure 10
).
NOTE:
The gas supply line should not be connected to the appliance until step
11. Connect the Gas Line
(
Page 37
).
NOTE:
ONLY a licensed installer should perform these steps—strictly per NFPA guidelines. Installing a gas supply
line from the fuel supply to the appliance involves numerous considerations, including materials, protection, sizing,
location, controls, pressure, sediment, and more.
NOTE:
Gas lines must be routed, assembled, and made of materials that are in strict accordance with local codes and
regulations. Never use galvanized or plastic pipe.

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).
NOTE:
• All fireplaces are factory-equipped with a flexible gas line connector and 1/2” shutoff valve (
Figure 34
).
• See
Massachusetts Horizontal Vent Requirements
for additional requirements for installations in the state of
Massachusetts in the USA.
• 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.
• A sediment trap in the supply line as close as possible to the fireplace is recommended.
