Installing Gas Piping to Fireplace Location (Cont.) Connecting Fireplace To Gas Supply

INSTALLATION

Continued

CONNECTING FIREPLACE TO GAS SUPPLY 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.

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 14).

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.

Manual background 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 15. 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.

1.If fireplace screen and floor are still installed, see Removing Fireplace Screen and Floor Assembly, pages 8 and 9.

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

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 16). The flexible gas supply line connection to the equipment shutoff valve should be accessible.

3.Attach the flexible gas line to gas supply (see Figure 16). Check tightness of flexible gas line attached to gas regulator of fire- place (see Figure 16).

4.Check all gas connections for leaks. See Checking Gas Con- nections, page 13.

5.Replace fireplace floor assembly. Feed flexible gas line into fireplace base area while replacing fireplace floor assembly. Make sure the entire flexible gas line is in fireplace base area.

Note: Be careful of wires and components on underside of fireplace floor. Reattach fireplace floor assembly with screws removed in step 3 of Removing Fireplace Screen and Floor Assembly, pages 8 and 9.
