INSTALLATION

Continued

We recommend that you install a sediment trap in supply line as shown in Figure 21, 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 22).

NOTICE: Most building codes do not permit concealed gas connections. A flexible gas line is provided to allow accessibility from the fireplace (see Figure 22). 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 flex- ible gas line/equipment shutoff valve (see Figure 23).

CAUTION: Avoid damage to regulator.Holdgasregulatorwith wrenchwhenconnectingittogas piping and/or fittings (Thermo- stat-Controlled Models Only).

CAUTION: Avoid damage to gas control. Hold gas control with wrench when connecting it to gas piping and/or fittings (Remote-Ready Models Only).

4.Check all gas connections for leaks. See Checking Gas Connections, below. Feed flexible gas line into fireplace. Make sure the entire flexible gas line is in fireplace.

CHECKING GAS CONNECTIONS

WARNING: Test all gas piping

and connections, internal and

external to unit, for leaks after

installing or servicing. Correct

all leaks at once.

WARNING: Never use an

open flame to check for a leak.

Apply a noncorrosive leak detec-
