Route a 1/2” (13 mm) gas line to the left side of the fi replace
(
Figure 10 or 10a
)
.
NOTE:
Gas lines must be routed, assembled, and made of materials that are in strict accordance with local codes and
regulations. All fi replaces are factory-equipped with a fl exible 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

.
NOTE:
•
All fi replaces are factory-equipped with a fl exible gas line connector and 1/2” shutoff valve
(
Figure 35
)
.
• 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 fi replace is recommended.
•
Check with the local building offi cial 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 insuffi cient 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.
