INSTALLATION

Continued

Installation must include an equipment shutoff valve, union and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from fireplace (see Figure 24).

IMPORTANT: Install an equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on and shutting off the gas to the appliance.

Check your building codes for any special re- quirements for locating equipment shutoff valve to fireplaces.

Apply pipe joint sealant lightly to male NPT threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged fireplace valves.

WARNING: Use pipe joint sealant that is resistant to liq- uid petroleum (LP) gas.

We recommend that you install a sediment trap in supply line as shown in Figure 24. Locate sediment trap where it is within reach for cleaning. Install in piping system between fuel supply and fireplace. Locate sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into fire- place 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.Remove fireplace screen. Remove two screws that hold fireplace screen in place for shipping. These screws are located near top of screen. Discard screws. Lift fireplace screen up and pull out to remove.

2.Remove screws that attach branch support to fireplace (see Figure 25). Carefully lift up branch support and remove from fireplace (see Figure 25).

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

NOTICE: Most building codes do not permit concealed gas connections. A flexible gas line is provided to allow accessibility from the fireplace (see Figure 25). The flexible gas supply line con- nection to the equipment shutoff valve should be accessible.

CAUTION: Avoid damage to

regulator. Hold gas regulator

with wrench when connecting it

to gas piping and/or fittings.
