INSTALLATION

Continued

We recommend that you install a sediment trap in supply line as shown in Figure 20, page 16. Locate sediment trap where it is within reach for cleaning. Install in piping system between fuel supply and heater. 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 controls. If sediment trap is not installed or is installed wrong, fireplace may not run properly.

CONNECTING EQUIPMENT SHUTOFF VALVE TO HEATER CONTROL

Installation Items Needed

•Phillips screwdriver

•sealant (resistant to propane/LP gas, not provided)

1. Open lower louver (see Figure 21).

NOTICE: Most building codes do not permit concealed gas connections. A flexible gas line is provided to allow accessibility fromthefireplace(seeFigure21). The flexible gas supply line con- nection to the equipment shutoff valve should be accessible.

2.Route flexible gas line, included, from fire- place control to equipment shutoff valve through side access holes in outer casing.

3.Apply pipe joint sealant lightly to male threads of gas connector attached to flexible gas line/ equipment shutoff valve (see Figure 22).
