INSTALLING
Continued
2. 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 16.
3. 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 8). 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.
