NOTE : The gas line connection may be made using 1/2"
rigid tubing or an approved

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

valve) in an accessible location. The main gas valve is for
turning on or shutting off the gas to the
fi
replace.
Check your building codes for any special requirements for
locating equipment shutoff valve to
fi
replaces.
Only persons licensed to work with gas
piping may make the necessary gas
connections to this appliance.
W
ARNING
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 28
. 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 con-
trols. If sediment trap/drip leg is not installed or is installed
wrong, burner system may not run properly.
