Since some municipalities have additional local codes it is always best to consult your local
authorities and the current edition of the National Fuel Gas Code ANSI.Z223.1, NFPA54. In Canada
CSA-B149 (1 or 2) Installation Code.

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.
Check your building codes for any special requirements
for locating equipment shutoff valve to fireplaces.
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 43. 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 collects moisture and contaminants and 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.
