INSTALLATION
Continued
We recommend that you install a sediment trap in
supply line as shown in Figure 25. Locate sedi-
ment trap where it is within reach for cleaning.
Install in piping system between fuel supply and
fireplace. Locate sediment trap where trapped mat-
ter is not likely to freeze. A sediment trap traps
moisture and contaminants. This keeps them from
going into fireplace gas controls. If sediment trap
is not installed or is installed wrong, fireplace may
not run properly.

ing fireplace floor assembly. Make sure the en-
tire flexible gas line is in fireplace base area.
