IMportant: Install main gas valve (equipment shutoff valve) in an accessible location. The main gas valve is
for turning on or shutting off the gas to the fireplace.

Apply pipe joint sealant lightly to male threads. This will
prevent excess sealant from going into pipe. Excess seal-
ant in pipe could result in clogged burner system valves.
We recommend that you install a sediment trap/drip leg
in supply line as shown in Figure 35. Locate sediment trap/drip leg where it is within reach for cleaning. Install
in piping system between fuel supply and burner system. Locate sediment trap/drip leg where trapped matter
is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into the
burner system gas controls. If sediment trap/drip leg is not installed or is installed wrong, burner system may
not run properly.
