INSTALLATION

Continued

Apply pipe joint sealant lightly to male NPT threads. This will prevent excess sealant from go- ing 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 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 fire- place gas controls. If sediment trap is not installed or is installed wrong, fireplace may not run properly.
