The Gas
Supply Line
NOTE: Have the gas supply line installed by a
qualified service technician in accordance with all
building codes.
NOTE: Before the first firing of the fireplace, the
gas supply line should be purged of any trapped air.
NOTE: Consult local building codes to properly size
the gas supply line leading to the 1/2 inch
(13 mm) hook-up at the unit.
This gas fireplace is designed to accept a 1/2 inch
(13 mm) gas supply line.
To install the gas supply line:
• A listed 1/2 inch (13 mm) manual shut-off valve and a
listed flexible gas connector are connected to the 1/2
inch (13 mm) inlet of the control valve.
• A 1/8 inch (3 mm) N.P.T. plugged tapping, accessible
for test gauge connection, should be provided for in
the gas supply line leading to the unit’s shut-off valve.
• Locate the gas line access hole in the outer casing of
the fireplace.
• Open the fireplace lower grille, insert the gas supply
line through the gas line hole, and connect it to the
shut-off valve.
• When attaching the pipe, support the control so that
the lines are not bent or torn.
• After the gas line installation is complete, use a soap
solution to carefully check all gas connections for
leaks.
