3. Install gas piping to fireplace location. This installation includes an approved flexible gas
line (if allowed by local codes) after the manual shutoff valve. The flexible gas line must be
the last item installed on the gas piping. See Installing Gas Piping to Fireplace Location,
page 15.
4. Place hearth base accessory against wall at installation location. Cut an access hole in hearth
top to run flexible gas line to fireplace (see Figure 9). Make sure to locate access hole so
cabinet mantel will cover it when installed. Note: You can secure base to floor using wood
screws. Countersink screw heads and putty over.
