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.
WARNING: Use pipe joint sealant that is resistant
to liquid petroleum (LP) gas.
We recommend that you install a sediment trap/drip leg in supply
line as shown in Figure 28. Locate sediment trap/drip leg where it is
within reach for cleaning. Install in piping system between fuel supply
and fireplace. Locate sediment trap/drip leg 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/drip leg is not installed or is installed wrong, fireplace may not
run properly.
