INSTALLATION

CAUTION: Use only new, black iron or steel pipe. Internally-tinned copper tubing may be used in cer- tain areas. Check your local codes. Use pipe of 1/2" diameter or greater to allow proper gas volume to fireplace. If pipe is too small, undue loss of volume will occur.

*Purchase the optional CSA design-certified equipment shutoff valve from your dealer. See Accessories, pages 34 and 35.

**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 22).

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 22. 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 23, page 14). Carefully lift up log base assembly and remove from fireplace (see Figure 23, page 14).

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.

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