Prepare the Fireplace Top Standoffs
1.
Bend each of the two (2) L-shaped standoff components, at the designated places, into a U-shape (
Figure 8
).
2.
Align the closed end of each U-shaped standoff component with the left/right side of the top, front of the
fireplace and the attachement holes in the top of the fireplace (
Figure 8
). Attach each U-shaped standoff
component with two (2) 5/16” hex head screws (
Figure 8
and
Figure 9
).
3.
Align the center support with the holes in the U-shaped standoff components and the top of the fireplace. Attach
the center support with two (2) 5/16” hex head screws in the top and two (2) screws in the bottom (
Figure 9
).
NOTE:
Position the center support with the larger holes at the bottom and the smaller holes at the top.

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 36
).

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
11. Connect the Gas Line
(
Page 36
).
NOTE:
• Never use galvanized or plastic pipe. Refer to
Table 12
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.
• Hire a qualified plumber or gas fitter 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 considerations of materials, protection,
sizing, locations, controls, pressure, sediment, and more. No one unfamiliar and unqualified should attempt
sizing or installing gas piping.
• See
Massachusetts Horizontal Vent Requirements
for additional requirements for installations in the state of
Massachusetts in the USA.
