GAS ROUGH-IN
Check local codes for requirements as to the size and type
of gas line required. See Figure 8 for location of gas inlet
holes in furnace cabinet.
Compounds used on threaded joints of gas pipe should
be resistant to the action of liquefied petroleum gases.
The gas line joints must be checked for leaks. This should
be done with a soap solution – watching for bubbles on
all connections. NEVER USE AN EXPOSED FLAME TO
CHECK FOR LEAKS.
A manual valve equipped with a 1/8" NPT plugged tapping
accessible for test gauge connection should be installed
immediately upstream of the gas supply connection to
the appliance. Some codes and ordinances require that
the manual valve be located outside the appliance. See
Figure 9.
The appliance and its individual shut off valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess
of ½ psig.
The appliance must be isolated from the gas supply piping
system by closing its individual manual shut off valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than ½ pig.
It is required by the National Fuel Gas Code that a drip
line be installed near the gas inlet. This should consist of a
vertical length of pipe tee connected into the gas line that
is capped on the bottom in which condensation and foreign
particles may collect.
