INSTALLATION
Continued
Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged fireplace valves.
CAUTION: Use pipe joint seal- ant that is resistant to liquid pe- troleum (LP) gas.
We recommend that you install a sediment trap in supply line as shown in Figure 18, page 10. Locate sediment trap where it is within reach for cleaning. Install in piping system between fuel supply and heater. Lo- cate 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.
NOTICE: Most building codes do not permit concealed gas con- nections. A flexible gas line is provided to allow connection with the fireplace (see Figure 20). The flexible gas supply line connec- tion to the equipment shutoff valve should be accessible.
4.Connect gas supply line to flexible gas line attached to gas regulator of fire- place insert (see Figure20). Use seal- ant on all male pipe threads.
5.Check all gas connections for leaks. See Checking Gas Connections, column 3 and page 12.
6.Replace log base assembly back into fire- place insert. Feed flexible gas line into fire- place insert base area while replacing log base assembly. Make sure the entire flex- ible gas line is in fireplace insert base area. Reattach log base assembly to fireplace insert with screws removed in step 2.
CHECKING GAS
CONNECTIONS
WARNING: Test all gas pip- ing and connections for leaks after installing or servicing. Cor- rect all leaks at once.
WARNING: Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once.
Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1. Disconnect appliance from its appli- |
ance main gas valve (control valve) and |
equipment shutoff valve from gas sup- |
ply piping system. Pressures in excess |
Installation Items Needed
•5/16" hex socket wrench or
•Phillips screwdriver
•sealant (resistant to propane/LP gas, not provided)
1.Remove fireplace insert screen. Re- move two screws that hold fireplace insert screen in place for shipping. These screws are located near top of screen. Discard screws. Lift fireplace insert screen up and pull out to remove.
2.Remove screws that attach log base as- sembly to fireplace insert (see Figure 19). Carefully lift up log base assem- bly and remove from fireplace insert (see Figure 19).
Note: If adding the G8010 series brick liner accessory, install it now. Follow instruc- tions in G8010 accessory kit.

3. | Pressurize supply piping system by ei- |
| ther using compressed air or opening |
| propane/LP supply tank valve. |
4. | Check all joints of gas supply piping |

5. | Correct all leaks at once. |
6. | Reconnect fireplace insert and equip- |
| ment shutoff valve to gas supply. Check |
| reconnected fittings for leaks. |
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1.Close equipment shutoff valve (see Fig- ure 21).
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 insert (see Figure 2, page 3).
