Cleaning the Sediment Trap 
The sediment trap removes contaminants (moisture and 
fine  particles)  from  gaseous  fuels  before  they  enter  the 
fuel regulator. Accumulated moisture and  particles  must 
be emptied from the  sediment  trap per local codes and 
guidelines. 
Proceed as follows to cle
an sediment trap:
1. Rem
ove intake side panel. See Intake Side Panel 
Removal.
2. T
urn generator fuel supply OFF.
3. See Figure 4-10. Unscrew and remove cap (A).

4. Use 
a  clean-out  tool  (not  provided)  to  remove 
accumulated moisture and  particles  from  cap and 
body (B).
5. Wipe
 inside of each component with a clean, dry, 
lint-free cloth.
6. Sea
l threads of cap with appropriate sealing com-
pound. Install cap and hand-tighten. 
7. T
ighten  cap  with  an  appropriately  sized  pipe 
wrench. DO NOT overtighten.
8. T
urn generator fuel supply ON. Inspect for leaks by 
spraying all connection points with a non-corrosive 
gas leak detection fluid. The solution should not be 
blown away or form bubbles.
9. Install intake side panel. 
Post Maintenance Checks
1. Perform required maintenance procedure(s).
2. Install 
intake side panel and front panel if removed. 
(See  Intake Side Panel Removal and Front 
Access Panel Removal.)
3. Install 7.5A
 fuse in control panel.
4. Complete Install W
izard information. 
5. Pr
ess AUTO button on control panel. Allow unit to 
run for one minute with no load (if running during a 
utility outage).
6. Set 
MLCB (generator disconnect) on generator to 
ON (CLOSED).
7. T
urn main utility disconnect ON (CLOSED). 
The system is now in AUTO. 
NOTE: If 
correct utility is present at this time, generator 
will perform its usual shutdown process.
Performing Fuel System Leak Test
All  products  are  factory-tested  before  shipping  to  verify 
the  performance  and  integrity of the fuel system. How-
ever, it is important to perform a final fuel system leak test 
bef
ore  starting  the  generator. The  entire  fuel  system 
should be tested from supply to regulator.
See  Figure 4-11.  Perform  a  final  fuel  system  leak  test 
after generator installation. The 
test will identify possible 
leaks at all connection points (A).
It is best practice to perform a fuel system leak test 
du
ring normally-scheduled maintenance.
Figure 4-11. Connection Points to Leak Check
Inspect for leaks by spraying all connection points with a 
no
n-corrosive  gas  leak  detection  fluid.  The  solution 
should not be blown away or form bubbles.

DANGER
Explosion and fire. Fuel and vapors are extremely
flammable and explosive. No leakage of fuel is
permitted. Keep fire and spark away. Failure to do
so will result in death or serious injury.
