CONNECT THE GAS

NOTE: The gas line connection may be made using 1/2"
rigid tubing or an approved fl ex 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 valve must be installed upstream of
the appliance. Union tee and plugged 1/8" NPT pressure
tapping point should be installed upstream of the appliance.

Sediment Trap/Drip Leg
A manual shutoff valve must be installed
upstream of the appliance. Union tee
and plugged 1/8" NPT pressure tapping
point should be installed upstream of the
appliance. Figure 17
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 17. 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 contami-
nants 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.
Use pipe joint sealant that is resistant to
liquid petroleum (LP) gas.
