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 valve.
We recommend that you install a sediment trap/drip leg in
supply line as shown in
Figure 41
. 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 collects moisture and contami-
nants and 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.
