CONNECTING FIREPLACE TO GAS SUPPLY

OWNER’S MANUAL

INSTALLATION

CONNECTING FIREPLACE TO GAS SUPPLY

Installation must include a manual 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 17).

Check your building codes for any special requirements for locating manual shutoff valve to fireplaces.

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.

Manual background CAUTION: Use pipe joint seal- ant that is resistant to liquid pe- troleum (LP) gas.

Install sediment trap in supply line as shown in Figure 17. Locate sediment trap where it is within reach for cleaning. Locate sedi- ment 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 sedi- ment trap is not installed or is installed wrong, fireplace may not run properly.

1.Remove fireplace screen. Remove two screws that hold fireplace 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, page 12). Carefully lift up log base as- sembly and remove from fireplace (see Figure 18).

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

3.Route flexible gas line provided by in- staller from manual shutoff valve to fireplace. Route flexible gas supply line through one of the access holes.

NOTICE: Most building codes do not permit concealed gas con- nections. A flexible gas line is provided to allow accessibility from the fireplace (see Figure 19). The flexible gas supply line con- nection to the manual shutoff valve should be accessible.

4.Attach a 45° flare union gas connector to flexible gas line from gas supply (see Figure 19). Connect flare union to flex- ible gas line attached to gas regulator of fireplace (see Figure 19).

5.Check all gas connections for leaks. See Checking Gas Connections, page 12.

6.Replace log base assembly back into fireplace. Feed flexible gas line into fire- place base area while replacing log base assembly. Make sure the entire flexible gas line is in fireplace base area. Reat- tach log base assembly to fireplace with screws removed in step 2.
