Gas piping to the boiler must be sized to deliver adequate gas for the boiler to fi re at the nameplate input at an inlet 

pressure between the minimum and maximum values shown on the rating plate. For more information on gas line 
sizing, consult the utility or the National Fuel Gas Code.

 

Figure 8.1 shows typical gas piping connection to the FCM boiler. A sediment trap must be installed upstream of all gas 

controls. Install the factory provided manual shut-off valve outside the jacket with a 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 ½ psi. When pressure testing the gas system at pressures of ½ psi or less, isolate the boiler 
from the gas supply system by closing its individual manual shut-off valve.
