GAS PIPING
Proper sizing of gas piping depends on the cubic feet per
hour of gas flow required, specific gravity of the gas and the
length of run. National Fuel Gas Code Z223.1 or CAN/CGA
B149.1 or .2 should be followed in all cases unless super-
seded by local codes or gas company requirements. Refer to
Tables 5 and 6.
The heating value of the gas may differ with locality. The
value should be checked with the local gas utility.
NOTE: There may be a local gas utility requirement specify-
ing a minimum diameter for gas piping. All units
require a 1/2 inch pipe connection at the gas valve.
GAS CONNECTION
The gas supply line can be routed through the hole located
on the left side of the unit. Refer to Figure 7 to locate these
access openings. Typical supply piping arrangements are
shown in Figure 5.
Gas piping recommendations:
1. A drip leg and a ground joint union must be installed in
the gas piping.
2. When required by local codes, a manual shut-off valve
may have to be installed outside of the unit.
3. Use wrought iron or steel pipe for all gas lines. Pipe dope
should be applied sparingly to male threads only.
