8.6 — Gaseous Fuel System Checklist
NOTE: See Chapter 5 for more information.
 Are fuel supply lines properly sized and installed? Were fuel supply lines purged and leak tested?
 Are sediment traps and drip legs installed to remove water and condensate from the gas flow?
 Is the fuel pressure regulator properly sized?
 Is a pressure test port installed before the fuel shutoff solenoids at the inlet to the unit mounted regulator?
 Does the generator have a dedicated fuel line which is not shared with any other appliances?
 Is the regulator sized to have a fuel flow delivery rating (CFH) at least 10% greater than the 100% rated kW fuel con-
sumption requirement of the generator?
 Is the fuel pressure regulator approved for a mechanized engine application?
 Does the fuel pressure regulator have an accuracy rating of 1% or less and/or have a maximum allowable pressure
drop of 1-2 inches w.c. under all operating conditions, that is, static, cranking, running at no load, and running at full
load (as measured at the primary fuel pressure regulator)?
 Does the fuel pressure regulator have a spring rating of 5-14 inches w.c.?
 Does the system use black iron piping or other approved gas line?
 Is the gas line rigidly mounted and protected against vibration?
 Is a length of flexible hose installed between the generator connection point and the rigid supply piping? Is the flexi-
ble hose straight without bends, twists or kinks?
 Is the piping correctly sized to maintain the required supply pressure and volume under varying load conditions?
 Was an approved pipe sealant or joint compound used on all threaded fittings?
 Is a fuel shutoff valve installed near the unit? Was proper operation of the fuel shutoff valve verified?
 Was the Final Operating Test performed to verify that the system operates correctly in all modes of operation?
 Is there any evidence of leakage at any hoses, clamps or fittings?
 Do these parameters meet all applicable codes and local jurisdiction?
8.7 — Electrical System Checklist
NOTE: See Chapter 6 for more information.
 Is all wiring correctly sized for load and length of run?
 Is all wiring correctly routed?
 Is all wiring correctly connected?
 Are wire lugs fastened to buss bars using appropriate hardware? Is hardware properly tightened to specified torque?
 Are all other terminals correctly tightened using the specified torque?
 Are batteries correctly sized?
