Sediment Trap/Drip Leg
Apply pipe joint sealant lightly to male threads. This will
prevent excess sealant from going into pipe. Excess seal-
ant 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 28. 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 contami-
nants. 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.
