We recommend that you install a sediment trap/drip leg in supply line as shown in Figure 17. 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.
