CHECKING GAS CONNECTIONS

INSTALLATION

Continued

2.Remove screws that attach log base assembly to fireplace (see Figure 23). Carefully lift up log base assembly and remove from fireplace (see Figure 23).

Note: If adding the G8005 series brick liner acces- sory, install it now. Follow instructions in G8005 accessory kit.

PRESSURE TESTING GAS SUPPLY PIPING SYSTEM CAUTION: Do not pick up log base assembly by burner. This could damage burner. Only handle base by grates.

3.Route gas line (provided by installer) from equipment shutoff valve to fireplace. Route flexible gas supply line through one of the access holes.

NOTICE: Most building codes do not permit concealed gas connections. A flexible gas line is provided to allow accessibility from the fireplace (see Figure 24). The flexible gas supply line con- nection to the equipment shutoff valve should be accessible.

4.Attach the flexible gas line to gas supply (see Figure 24). Check tightness of flexible gas line attached to gas regulator of fireplace (see Figure 24).

5.Check all gas connections for leaks. See Checking Gas Connections.
