* Purchase the optional CSA design-certified equipment shutoff
valve from your dealer. See Accessories, pages 22 and 23
CAUTION: 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 17. 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.
INSTALLATION
Continued
Installation must include an equipment shutoff valve, and a plugged
1/8" NPT tap. Locate NPT tap within reach for test gauge hook up.
NPT tap must be upstream from fireplace (see Figure 17).
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 thread sealant on flare threads.
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 18). Carefully lift up log base assembly and remove
from fireplace (see Figure 18).
Note: If adding the G8000 series brick liner accessory, install it
now. Follow instructions in G8000 accessory kit.
CAUTION: Do not pick up log base assembly by
burners. This could damage burners. Only handle
base by grates.
NOTICE: Most building codes do not permit con-
cealed gas connections. A flexible gas line is pro-
vided to allow accessibility from the fireplace (see
Figure 19). The flexible gas supply line connection to
the equipment shutoff valve should be accessible.
CAUTION: Use only new, black iron or steel pipe.
Internally-tinned copper tubing may be used in certain
areas. Check your local codes. Use pipe of 1/2" diam-
eter or greater to allow proper gas volume to fireplace.
If pipe is too small, undue loss of volume will occur.
