Route the Gas Supply Line to the Fireplace
1.
Route a 1/2” (13 mm) gas line to the left side of the fireplace
(
Figure 8
)
.
NOTE:
Gas lines must be routed, assembled, and made of materials that are in strict accordance with local codes and
regulations. All fireplaces are factory-equipped with a flexible gas line connector and a 1/2” shutoff valve
(

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).
The gas supply line should not be connected to the appliance until step
12. Connect the Gas Line
(
Page 39
).
NOTE:
• All fireplaces are factory-equipped with a flexible gas line connector and 1/2” shutoff valve
(
Figure 31, Page 40
)
.
• 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.
• Check with the local building official for local code requirements (e.g., Are below grade penetrations of the gas
line allowed?, etc).
CAUTION
If propane is used, be aware that with a tank that is too small (i.e., under 100 lbs, if this
is the only gas appliance in the dwelling—see NPFA 58), there may be a loss of pressure.
This can result in insufficient fuel delivery that can cause sooting, delayed ignition, or other
malfunctions. Any damage resulting from an improper installation is not covered by the
limited warranty.
