The Gas
Supply Line
NOTE: Have the gas supply line installed in
accordance with local building codes by a
qualified installer approved and/or licensed as
required by the locality. (In the Commonwealth
of Massachusetts installation must be
performed by a licensed plumber or gas fitter).
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 (and the Commonwealth of Massachusetts
approved) 1/2 inch (13mm) tee-handle manual shut-
off valve and a listed flexible gas connector are
connected to the 1/2 inch (13mm) inlet of the con-
trol valve. NOTE: If substituting for these compo-
nents, please consult local codes for compliance.
• The gas line may be run from either side of the
fireplace provided the hole in the outer wrap does
not exceed 2 inches in diameter and it does not
penetrate the airtight firebox.
• The gap between the supply piping and gas
access hole can be plugged with non-combus-
tible insulation to prevent cold air infiltration.
• Locate the gas line access hole in the outer
casing of the fireplace.
• Remove decorative door by lifting up away to gain
access to the gas control and shut-off valve,
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, all
connections must be tightened and checked for
leaks with a commercially available, non-corro-
sive leak check solution. Be sure to rinse off all
leak check solution following testing.
WARNING: DO NOT USE AN OPEN
FLAME TO CHECK FOR GAS LEAKS.
