Check your building codes for any special requirements for locat-
ing equipment 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 burner system valves.
We recommend that you install a sediment trap/drip leg in supply
line as shown in Figure 33. Locate sediment trap/drip leg where it is within reach for cleaning. Install in piping system between
fuel supply and burner system. 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 the burner system gas controls. If sediment trap/drip leg is not
installed or is installed wrong, burner system may not run properly.
