INSTALLATION
Installing Gas Piping to Fireplace Location (Cont.)
Connecting Fireplace to Gas Supply
* Purchase the optional CSA design-certified equipment shutoff
valve from your dealer. See Accessories, pages 28 through 30.
** Minimum inlet pressure for purpose of input adjustment.
Installation must include an equipment shutoff valve, union, and
plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge
hook up. NPT tap must be upstream from fireplace (see Figure 18).
IMPORTANT:
Install equipment shutoff valve in an accessible
location. The equipment shutoff valve is for turning on or shutting
off the gas to the appliance.
Check your building codes for any special requirements for locating
equipment shutoff valve to fireplaces.
Apply pipe joint sealant lightly to male NPT threads. This will prevent
excess sealant from going into pipe. Excess sealant in pipe could
result in clogged fireplace valves. Never use sealant on flare threads.
WARNING: Use pipe joint sealant that is resistant
to liquid petroleum (LP) gas.
We recommend that you install a sediment trap in supply line as
shown in Figure 18. Locate sediment trap where it is within reach for
cleaning. Install in piping system between fuel supply and fireplace.
Locate sediment trap where trapped matter is not likely to freeze. A
sediment trap traps moisture and contaminants. This keeps them
from going into fireplace gas controls. If sediment trap is not
installed or is installed wrong, fireplace may not run properly.
CONNECTING FIREPLACE TO GAS SUPPLY
Installation Items Needed
• 5/16" hex socket wrench or nut-driver
• Phillips screwdriver
• sealant (resistant to propane/LP gas, not provided)
1. Remove fireplace screen. Remove two screws that hold fire-
place screen in place for shipping. These screws are located
near top of screen. Discard screws. Lift fireplace screen up
and pull out to remove.
2. Remove screws that attach log base assembly to fireplace (see
Figure 19). Carefully lift up log base assembly and remove
from fireplace (see Figure 19).
Note:
If adding the G8000A series brick liner accessory, install it
now. Follow instructions in G8000A accessory kit.
CAUTION: Do not pick up log base assembly by
burner. This could damage burner. Only handle base
by grates.

NOTICE: Most building codes do not permit concealed
gas connections. A flexible gas line is provided to
allow accessibility from the fireplace (see Figure 20,
page 13). The flexible gas supply line connection to the
equipment shutoff valve should be accessible.
