INSERT INSTALLATION
WARNING
Only persons licensed to work with gas piping may make
the necessary gas connections to this appliance.
NOTE: The gas line connection may be made using 1/2"
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.Z223.1, NFPA54. In
Canada CSA-B149 (1 or 2) Installation Code.
A listed manual shutoff is factory installed upstream of

A manual shut-off valve is factory installed upstream
of the appliance. Union tee and plugged 1/8" NPT
pressure tapping point should be installed upstream
of the appliance. Figure 12
Apply pipe joint sealant lightly to threads. This will prevent
excess sealant from going into pipe. Excess sealant in pipe
could result in clogged burner system valves.We recom-
mend that you install a sediment trap/drip leg in supply
line as shown in Figure 12. 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.
Use pipe joint sealant that is resistant to liquid
petroleum (LP) gas.
