rigid tubing or an approved flex connector. 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.Z3.1, NFPA54. In
Canada CSA-B149 (1 or ) Installation Code.
A listed manual shutoff valve must be installed upstream

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.

Sediment Trap/Drip Leg
We recommend that you install a sediment trap/drip leg
in supply line as shown in
Figure 37
. 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 contami-
nants. 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.
