Installing Non-Combustible Front Fireboard Standoff
A non-combustible standoff board is provided with the fireplace to prevent overlap of drywall or other material of portions of the fireplace that may
be prone to the buildup of heat. It is supported by a middle bracket and two side brackets.
NOTE:
DRL3535TEN and DRL3545TEN models require a 4.75” non-combustible fireboard (provided) while DRL2035TEN and DRL2045TEN models
require a 2.75” non-combustible board (provided).
The gas supply line should not be connected to the appliance until step
14. Connect the Gas Line
(
Page 44
).
NOTE:
• All fireplaces are factory-equipped with a flexible gas line connector and 1/2” shutoff valve
(
Figure 35, Page 44
)
.
• 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. 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
(see
Figure 34
)
.
• Check with the local building official for local code requirements (e.g., Are below grade penetrations of the gas line allowed?, etc).
4.
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 10
)
.
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
(
Page 44
)
.
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).
