We recommend that you install a sediment
trap in supply line as shown in Figure 14, page
13. Locate sediment trap where it is within
reach for cleaning. Install in piping system
between fuel supply and heater. Locate sedi-
ment trap where trapped matter is not likely
to freeze. A sediment trap traps moisture and
contaminants. This keeps them from going
into fireplace controls. If sediment trap is not
installed or is installed wrong, fireplace may
not run properly.
