pressure between the minimum and maximum values shown on the rating plate. For more information on gas line sizing,
consult the utility or Chapter 2 of the National Fuel Gas Code.
Figure 10 shows typical gas piping connection to the CGS-C boiler. A sediment trap must be installed upstream of all gas
controls. Install a manual shut-off valve outside the jacket and ground joint union as shown.
The boiler and its gas connection must be leak tested before placing the boiler in operation. When doing this, the boiler
and its individual shut-off must be disconnected from the rest of the system during any pressure testing of that system at
pressures in excess of 1/2 psi. When pressure testing the gas system at pressures of 1/2 psi or less, isolate the boiler from the
gas supply system by closing its individual manual shut-off valve.
