INSTALLATION

Continued

WARNING: Never connect natural gas fireplace insert to private (non-utility) gas wells. This gas is commonly known as wellhead gas.

For propane/LP units, the installer must supply an external regula- tor. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11 and 14 inches of water. If you do not reduce incoming gas pressure, heater regulator damage could occur. Install external regulator with the vent point- ing down as shown in Figure 17. Pointing the vent down protects it from freezing rain or sleet.

CAUTION: Use only new, black iron or steel pipe.

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 heater. 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 insert gas controls. If sediment trap is not installed or is installed wrong, fireplace may not run properly.

CSA Design-Certified Equipment

Shutoff Valve With 1/8" NPT Tap*

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 insert. If pipe is too small, undue loss of volume will occur.

CONNECTING FIREPLACE INSERT TO GAS SUPPLY

Installation must include an equipment shutoff valve, and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from fireplace insert (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.

• sealant (resistant to propane/LP gas, not provided)

1.Remove fireplace insert screen. Remove two screws that hold fireplace insert screen in place for shipping. These screws are located near top of screen. Discard screws. Lift fireplace in- sert screen up and pull out to remove.

2.Remove screws that attach log base assembly to fireplace in- sert (see Figure 19, page 12). Carefully lift up log base assem- bly and remove from fireplace insert (see Figure 19, page 12).

Note: If adding the G8010 series brick liner accessory, install it now. Follow instructions in G8010 accessory kit.

CAUTION: Do not pick up log base assembly by burners. This could damage burners. Only handle base by grates.

3.Route gas supply line through access opening of fireplace in- sert (see Figure 2, page 3).
