NOTE: Have the gas supply line installed in accordance
with local building codes by a qualified installer ap-
proved 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 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 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 control valve. NOTE: If substi-
tuting for these components, please consult local codes
for compliance.
• 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.
• Remove the decorative door on the unit by pulling away
from the unit to release it from the clips on each side.
• Locate the gas line access hole in the outer casing of the
fireplace.
• 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-avail-
able, non-corrosive leak check solution. Be sure to rinse off all
leak check solution following testing.
