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.
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 9. 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.
