INSTALLATION

Continued

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.

We recommend that you install a sediment trap in supply line as shown in Figure 19, page 13 . Locate sediment trap where it is within reach for cleaning. Install in piping system between fuel supply and heater. Locate sediment 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.

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

2.Apply pipe joint sealant lightly to male threads of gas connec- tor attached to flexible gas line (see Figure 21). Connect flex- ible gas line to flexible gas line attached to gas valve of fire- place (see Figure 21).

3.Check all gas connections for leaks. See Checking Gas Con- nections, page 14.

4.Feed flexible gas line into fireplace base area. Make sure the entire flexible gas line is in fireplace mantel base area.

CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting it to gas piping and/or fittings.

NOTICE: Most building codes do not permit con- cealed gas connections. A flexible gas line is pro- vided to allow accessibility from the fireplace (see Figure 21). The flexible gas supply line connection to the equipment shutoff valve should be accessible.
